This maintenance guide comes from years of hands-on customer support for robot vacuum owners, now published here for anyone to use rather than kept inside one support inbox. Several of the models and parts named below link out to Plus.Parts®, the maintenance parts store run by the same company behind this site, and that is also where much of the experience behind this guide comes from.
The Ecovacs Deebot T20 series combines 6,000 Pa suction with dual OZMO Turbo spinning mop discs at 180 RPM, backed by an Omni station that washes those pads at 55°C and dries them with hot air between missions. This guide covers the complete maintenance schedule for the Deebot T20 Omni
, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, Deebot T20e Omni, T20 Omni Station (CH2232), Ecovacs DLX23, and Ecovacs DLX53, with a model comparison of how each variant differs in service scope.
Why Deebot T20 series robots need more frequent maintenance
Dual spinning mop pads impose a higher per-session load on disc fibres than flat-drag mopping systems
The OZMO Turbo assembly drives each mop disc at 180 revolutions per minute with a consistent downward contact pressure against the floor surface. On a flat-drag platform the mop pad travels in a single forward direction, and each fibre accumulates distance at a roughly uniform rate across the pad face. On the T20, each revolution drives the outer-circumference fibres through a substantially longer circular path than the fibres near the spindle, so the outer band accumulates mechanical wear significantly faster than the inner zone. The outer fibres glaze and compact first, losing their ability to lift captured soil from the floor. That compacted outer zone continues to contact the surface and redistributes collected residue rather than removing it, meaning the cleaning quality of each pass degrades silently before any visual change is apparent on the pad surface. The 55°C auto-wash cycle in the Omni dock manages ongoing hygiene between pad swaps but cannot restore compacted fibre structure once the mechanical damage has occurred. Every T20 model, from the Deebot T20 Omni to the Deebot T20e Omni, runs through mop pad service intervals on a shorter calendar cycle than owners transitioning from flat-drag platforms are accustomed to expecting.
6,000 Pa suction saturates the HEPA filter at a faster rate than lower-pressure platforms
The T20 moves a significantly larger volume of air per session than a typical 2,000 to 3,000 Pa robot vacuum and pulls correspondingly more fine particulate through the HEPA medium with each pass. The filter shifts from white to mid-grey on a shorter cycle than owners of lower-pressure platforms expect. A filter at mid-grey saturation restricts airflow through the pleated medium, and the suction motor compensates by drawing additional current to maintain the target pressure. That sustained extra current generates heat in the motor assembly at the same time the impeller is already operating near its rated load, compressing effective motor service life ahead of the normal replacement window if the filter is not swapped at the correct interval. The colour shift from white to mid-grey is the practical replacement trigger, not a perceptible drop in suction at the floor nozzle, because by the point a user can detect reduced suction the filter has already been degrading motor performance for several weeks. On the Deebot T20 Pro Plus and Deebot T20 Max Omni, which are most commonly deployed in larger homes with extended daily sessions, the two-month filter interval is the practical target rather than the upper boundary of the recommended range.
The 55°C dock wash cycle links robot and station maintenance into a single coupled chain
The T20 Omni Station (CH2232) washes the spinning pads at approximately 55°C after each mopping session, then dries them with hot air over a cycle of around two hours before the robot is cleared for its next mission. At wash temperature, dissolved minerals in mains water precipitate onto the spray nozzles and drainage channel faster than in a cold-rinse system. A nozzle carrying even a thin limescale film delivers water unevenly across the two pad surfaces, so one disc returns to the floor surface noticeably wetter than the other and produces asymmetric floor coverage on the next session. The dirty-water tank collects the combined residue of floor soil, pad fibres, and mineral wash-off from every cycle. A tank rinsed every two to three days rather than left to accumulate between infrequent empties prevents that residue from re-entering the next wash cycle, where it would progressively raise the organic and mineral load on the spray nozzles and shorten their effective service life. The maintenance obligations of the robot consumables and the dock components are directly coupled: attending to one side while deferring the other results in accelerated degradation across the entire platform.
The mop auto-lift mechanism collects debris at each carpet transition on the robot undercarriage
When the T20 detects a transition from hard floor to carpet, both mop plates raise approximately 9 mm to prevent the spinning discs from dampening the pile. The lift mechanism sits in a frame on the underside of the chassis that accumulates hair, lint, and floor grit at each rug-edge crossing. A lift frame carrying accumulated debris cannot complete the full 9 mm travel, and a plate that reaches only two-thirds of the designed clearance before stalling still allows the spinning disc to brush against low-pile carpet surfaces and leave damp tracks. Owners typically attribute this symptom to a mopping sensitivity setting or a dock configuration issue rather than to a mechanical clearance fault caused by a preventable accumulation point on the undercarriage. Clearing the lift frame and the plate mounting clips at every pad swap, rather than only when damp tracks appear on carpet, keeps the mechanism within its designed travel range and avoids a diagnostic pattern that originates from accumulated debris rather than any component fault in the robot or dock.

Shared consumables architecture across all T20 robot variants
The Deebot T20 Omni, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, Deebot T20e Omni, Ecovacs DLX23, and Ecovacs DLX53 share an identical robot chassis and the same hardware core. All service intervals in this guide apply equally to every named robot model because the consumables specification, the suction motor configuration, and the mop disc mounting system are uniform across the entire range. Where these variants differ is in the accessory bundle included in the retail box and in dock finish options offered in particular regional markets, not in the replacement parts or the service schedules themselves.
The T20 Omni Station as an integral part of the T20 service scope
The T20 Omni Station (CH2232) is the dock unit paired with every T20 robot variant. It houses the water heating element for the 55°C pad wash, the hot-air drying fan, the dirty-water tank, the clean-water reservoir, the auto-empty dustbag compartment, and the spray nozzles. Owners who maintain robot consumables on schedule but defer dock maintenance will encounter declining pad wash quality, progressive dock odour from accumulated tank residue, and auto-empty transfer failures that originate in the station hardware rather than in any fault within the robot body. The station’s maintenance obligations sit alongside the robot consumables rather than below them in priority.
Replacement parts and service intervals
Main brush roll
Clean every one to two weeks. Replace every six to nine months. The T20 platform uses a single floating rubber brush with spiralling vanes rather than bristle fibres. The floating mount allows the brush to conform passively to minor floor-level variations during each suction pass, improving debris capture across tile grout lines and hardwood board joins. The primary debris accumulation points are the two end caps, where the brush shaft passes through the bearing seats. Hair and compacted dust at the end caps introduce lateral drag on the shaft that the floating suspension cannot compensate for, loading the brush motor with a sustained resistance that is undetectable during a running session but accumulates over weeks of daily use. Inspect both end caps at every cleaning interval by removing the brush and rotating it by hand. Any resistance beyond what is present with clear end caps indicates compacted material that should be removed before reinserting the brush. Replace the roll when the rubber vanes show permanent flattening, when floor-surface grip is visibly reduced, or when end cap clearing is required more than once within a single week, as that cadence is a reliable early indicator that the brush has reached the end of its efficient working life. An individual main brush roll is not yet listed as a separate product for any T20 configuration, so wherever a specific model is named in this guide the link leads to that model’s Maintenance Set, which includes the brush roll as standard content, for example on the Deebot T20 Omni, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, and Deebot T20e Omni.
HEPA filter
Clean every one to two weeks by tapping the frame firmly on all four sides over a waste bin to dislodge surface loading from the pleated medium. Replace every two to three months under daily use. Use the colour shift from white to mid-grey as the replacement trigger rather than waiting for a perceptible suction reduction at the floor nozzle, because by the point reduced suction is detectable the filter has already been degrading motor performance for several weeks. Do not wash the filter under running water or wipe the pleats with a damp cloth. Water saturation collapses the electrostatic capture layer in the HEPA medium irreversibly, and a filter that passes a visual inspection after washing no longer captures particulate at its rated 0.3-micron threshold. It should be treated as failed regardless of its appearance after wetting. On the Deebot T20 Pro Plus and Deebot T20 Max Omni, which are most frequently deployed in larger homes with extended daily sessions, the two-month interval is the practical operating target rather than the three-month ceiling of the recommended range. A standalone HEPA filter is not yet listed as its own product for any T20 model, so the two links above and every other model mention in this guide lead to that model’s Maintenance Set, which includes the filter as standard content.
OZMO Turbo mop pads
The Omni station auto-washes the spinning pads at 55°C after each mopping session, managing routine hygiene between scheduled pad replacements. Inspect both pads every two months and replace when the surface texture has reduced noticeably, when the fibres feel stiff or compacted after a completed wash-and-dry cycle, or when persistent discolouration remains across the pad face despite multiple hot-wash cycles. Do not extend the replacement interval past two months on the basis of visual appearance alone. The mechanical degradation of pad fibre structure from sustained 180 RPM spinning contact precedes visible surface deterioration by several weeks, and a pad operating past its service life actively redistributes captured soil back across the floor surface with each pass rather than simply cleaning less effectively. In pet-owning households or homes with high-traffic hard floors, inspect both pads at six weeks and replace on observed fibre condition rather than calendar date. Individual mop pads are listed separately for every T20 robot model in this range: the Deebot T20 Omni
, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, Deebot T20e Omni, Ecovacs DLX23, and Ecovacs DLX53 pad pair can each be ordered on their own rather than as part of the full Maintenance Set. No mop pad listing exists for the T20 Omni Station itself, which is expected since the station is a dock unit rather than a mopping robot.
Side brushes
Inspect weekly. Replace every three to six months as a matched pair. The T20 deploys a dual side brush configuration, one brush positioned on each leading corner of the chassis, rather than the single side brush used on simpler platforms. Inspect each post weekly and remove hair or thread from the base using the supplied cleaning tool. Replace both brushes together even when only one shows obvious wear. Installing a new brush alongside a worn brush does not deliver the even wall-edge coverage that the dual-brush configuration requires, and the less-worn brush will typically reach visible failure within a few weeks of a single-unit replacement. A side brush whose bristles are bent, splayed, or no longer radiating evenly from the post cannot bridge the designed gap between the chassis edge and the skirting board. Because the T20 routes its cleaning path differently along each wall of the room, a single worn brush produces a visible debris line along only one wall, which is typically the first symptom owners notice that a matched-pair replacement is needed. Side brushes are not yet listed as a standalone product for any T20 model, so mentions of the Deebot T20 Omni, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, and Deebot T20e Omni throughout this section link to each model’s Maintenance Set, which includes the matched side brush pair as standard content.
Dock dustbag
The auto-empty dock houses a 2.5-litre dustbag and transfers the robot’s internal dustbin content into that bag at the end of each session. Replace the bag every four to eight weeks under daily use. A bag at or beyond its fill line cannot accept the transfer, causing the robot to complete its next session without an empty cycle and to stop mid-run with a bin-full notification. Do not empty the bag manually and reinstate it. The internal baffle that prevents fine dust from escaping into the dock airflow path collapses when the bag is opened and cannot be restored. A reused bag allows fine particulate to bypass the dock filter stage and accumulate on the fan housing and heating element, introducing a progressive source of dock odour over subsequent weeks that is difficult to trace without opening the station casing. The dock dustbag is listed as its own product for every model in the range: the Deebot T20 Omni
, Deebot T20 Pro, Deebot T20 Pro Plus, Deebot T20 Max Omni, Deebot T20e Omni, Ecovacs DLX23, Ecovacs DLX53, and the T20 Omni Station (CH2232) can each be ordered independently rather than as part of the full Maintenance Set.
Dock dirty-water tank and spray nozzles
Empty and rinse the dirty-water tank every two to three days, or more frequently in households where the robot mops daily across a large floor area. The T20 Omni Station (CH2232) completes a full pad wash after every mopping session, filling the dirty-water tank faster than stations that leave pad cleaning to the owner between uses. Rinse the tank with fresh water, wipe the gasket seal before reinserting, and inspect the tank seat for grit that could prevent a clean seal on reinstallation. A compromised seat allows water to track into the dock base cavity over repeated sessions. Inspect the spray nozzles monthly by wiping each nozzle face with a damp cloth to clear limescale deposits, or every two to three weeks in moderately hard-water areas. A thin limescale film is sufficient to deflect the spray angle and deliver water unevenly across the two pad surfaces before the nozzle appears visibly blocked from the exterior. If both pads consistently return from the dock with one side less clean than the other, inspect the nozzle on the underperforming side first before investigating the pads themselves.
Charging contacts
Wipe the robot charging contacts and the corresponding dock terminal contacts every four to six weeks using a dry cloth. The T20 returns to the Omni station after every session to charge, auto-empty, and complete the pad wash cycle, so the contact faces accumulate a film of floor dust and mop humidity on a shorter cycle than robots that dock only once or twice per day. A contaminated contact face does not immediately prevent charging but introduces a resistance that causes the station firmware to register a docking alignment fault before any actual charging failure occurs. Cleaning both sets of contacts takes approximately five seconds and prevents the alignment-fault diagnostic cycle that results from contacts that appear intact but carry a thin conductivity-reducing layer on their surface.
Battery
The Deebot T20 series uses an integrated rechargeable lithium-ion battery. Under daily use, a well-maintained battery delivers consistent runtime for two to three years before replacement is warranted. The practical signal for replacement is a sustained drop in runtime to below 60 to 70 minutes per charge cycle under normal operating conditions, rather than an in-app charge-level warning alone, which reflects charge acceptance rather than usable capacity. A battery that charges fully but no longer covers the robot’s mapped area in a single run is the clearest indication that capacity has declined beyond the threshold where runtime can be recovered by adjusting mission frequency. Keep the charging contacts on the robot and dock terminal clean at all times, as a resistive contact surface causes the station firmware to misread the charge acceptance rate and can partially mask genuine battery degradation. Do not leave the robot in a fully discharged state for extended periods. Sustained deep discharge below the minimum cell voltage accelerates permanent capacity reduction in the lithium-ion cells and shortens the functional battery service life relative to units kept on regular charge cycles.

Common problems and their maintenance causes
Mop leaving a dull streak or film on hard floors after a completed session
This is the most consistently reported symptom across the T20 platform and traces to mop pad condition in almost every instance. The outer-circumference fibres on each OZMO Turbo disc accumulate a glaze from sustained 180 RPM contact loading that the 55°C auto-wash cycle cannot reverse once the fibre structure has compacted. Replace both pads as a pair and run one full cleaning session on sealed hardwood or tile to confirm whether the result improves before investigating any other cause. If streaking continues after fresh pads are fitted, inspect the dock spray nozzles. A nozzle carrying even a thin limescale deposit deflects the spray pattern and delivers water asymmetrically across the two pad surfaces, so one disc returns to the floor noticeably dryer than the other and produces a consistent streak along one side of the robot’s mopping path. If both pads produce an equally poor result after a nozzle clean, rinse the dirty-water tank thoroughly before the next session. A tank that was not fully emptied can reintroduce dissolved soil into the pad wash water, depositing a thin residue film back onto the pad surface as the wash cycle contacts the fibres.
Dock emitting a sour or stale odour after a mopping session
The most common cause is a dirty-water tank that has not been rinsed within the previous two to three days. Residue held in the tank at wash temperature develops an odour more rapidly than owners typically expect, especially after sessions that collected pet hair, food debris, or organic material from kitchen or bathroom floors. Empty the tank, rinse with lukewarm water, wipe the gasket, and confirm the tank seat is free of grit before reinserting. If the odour returns within 24 hours of a clean tank installation, inspect the pad-drying fan vent on the station body. A vent partially blocked by accumulated floor dust prevents the hot-air drying phase from completing in full and leaves the pads damp enough to develop mildew between sessions. Clearing the vent allows the drying cycle to complete correctly and returns the pads fully dry before the next mission. On the Deebot T20 Pro Plus and Deebot T20 Max Omni, which run longer daily sessions and accumulate more pad residue each week, treating the two-to-three-day tank rinse as a fixed interval rather than an upper limit avoids the odour cycle entirely under normal conditions.
Suction noticeably weaker than when the robot was new
Replace the HEPA filter first. At 6,000 Pa a loaded filter produces a proportionally greater reduction in effective suction than on a lower-pressure platform, because the motor is operating near its rated airflow ceiling with limited headroom to compensate for restriction in the pleated medium. If suction remains reduced after a filter swap, check the main brush end caps. Compacted hair at the end caps restricts airflow through the brush aperture in a way that is not visible during a running session and reduces the effective suction at the floor nozzle without any accompanying change in motor tone or operational speed. If both filter and end caps are confirmed clear, check the auto-empty dustbag fill level. A bag at or near its fill line blocks the airflow path between the robot dustbin and the dock filter stage and can produce a suction deficit before the robot registers a bin-full notification in the app, particularly in firmware builds that monitor capacity by weight sensor rather than by optical detection.
Robot reporting a mop-plate error or pad-seat fault at start-up
This error most commonly indicates that a mop plate has not seated fully after the previous auto-wash cycle, typically because one of the magnetic mounting clips carries a compressed-fibre film left by pads that were near the end of their service life when last installed. Remove both pads, wipe each clip contact face thoroughly with a dry cloth, and reseat them firmly on their mounting points. If the error persists after reseating, examine each clip contact point under good light with the robot chassis face-down. A thin film of compacted fibre on the contact face prevents the magnetic connection from registering correctly and generates the seat-error flag without any visible mechanical damage to the clip or the mounting point. A clip contact requiring cleaning more than twice within a fortnight is a reliable early indicator that the pads are due for replacement rather than that any dock or robot hardware fault is present.
A visible debris line along one wall only after a complete cleaning run
One side brush has worn ahead of its counterpart. Because the T20 routes its wall-following path differently along each room edge, uneven wear between the two side brushes produces a coverage gap that appears along only one wall rather than uniformly around the perimeter. Replace both brushes as a matched pair even when the second brush passes a visual inspection. Installing a new brush alongside a worn brush does not deliver the even wall-edge coverage that the dual-brush configuration requires, and the less-worn brush will typically reach visible failure within a few weeks of a single-unit replacement. If a debris line persists immediately after a fresh matched pair is fitted, confirm that both brushes have clicked fully onto their drive posts. A brush that has not fully seated rotates with reduced extension and produces a coverage gap indistinguishable from a wear pattern on the first several runs after a swap.
Damp tracks on carpet after a mixed vacuum-and-mop session
The mop auto-lift mechanism is not reaching its full 9 mm clearance travel. On the T20 platform this almost always traces to a lift frame that has accumulated hair and floor grit at repeated rug-edge crossings. Clear the lift frame with the supplied cleaning tool, wipe the plate mounting clips, and run a test pass over a low-pile rug before committing the robot to a full session. If damp tracks persist after a clear lift frame is confirmed, inspect the underside of each mop plate for compacted debris that is preventing the plate from tilting fully upward when the lift signal fires. A plate that achieves approximately two-thirds of its designed clearance before stalling still allows the spinning disc to contact low-pile carpet surfaces even though the robot’s internal sensor reports the lift event as completed, producing damp marks that owners typically trace back to mopping settings rather than to a mechanical clearance issue on the undercarriage.
Dock failing to complete the auto-empty transfer or rejecting the robot on return
Dock acceptance relies on clean charging contacts for the alignment confirmation step that precedes the auto-empty sequence. A film of floor dust or mop humidity on the contact faces reads at the firmware level as a docking misalignment event before it causes an actual charging failure. Wipe the robot contacts and the dock terminals with a dry cloth and retry before investigating any other cause. If the dock continues to reject the robot after contacts are confirmed clean, check the dustbag fill level. A bag at or beyond its fill line cannot accept the debris transfer regardless of contact condition, and some firmware versions log the resulting event as a mechanical rejection rather than generating a bag-full notification in the app. Replacing the bag resolves the rejection without any further intervention in these cases.
What consistent maintenance protects over time
On the T20 platform the consumable chains are interdependent in ways that accelerate in proportion to how long any single item is deferred. A saturated HEPA filter forces the suction motor to draw additional current through a restricted airflow path, adding sustained heat to the drivetrain that also powers the brush roll impeller. A mop pad operating past its two-month service interval introduces more dissolved floor soil into the dock wash water per session than a fresh pad, raising the mineral and organic load deposited on the spray nozzles with every pump cycle. A nozzle with an advancing limescale build-up delivers water asymmetrically, reducing the effectiveness of the 55°C pad wash and advancing the next pad replacement date before the calendar interval is reached. A dirty-water tank not rinsed within the correct frequency reintroduces that accumulated residue into the next wash cycle, compounding the nozzle load further. The chain moves consistently toward shorter downstream consumable life whenever any single upstream item is deferred past its correct replacement point, and the rate of degradation across the system accelerates rather than remaining linear as each additional deferred item adds its contribution.
The Plus.Parts® Maintenance Set covers the complete T20 service scope in a single order: the floating rubber main brush, the HEPA filter, the twin OZMO Turbo mop pads, the dual side brushes, and the dock dustbag. Keeping a complete set on hand removes delivery lead time as a reason for extending any interval past its correct replacement point, which is the most common practical cause of a filter or mop pad running two to four weeks beyond the point where it is still delivering its rated performance for the platform.
How the T20 series models differ
Every T20 robot variant runs the same hardware core, the same consumable set, and the same service intervals. The practical differences between models come down to what is included in the retail bundle, how the unit is classified in the Ecovacs parts catalogue, and what deployment context the model is designed for. The sections below address each variant and what its designation means for owners ordering replacement parts or planning a service schedule.
Deebot T20 Omni and Ecovacs DLX23
The Deebot T20 Omni is the reference configuration of the T20 platform, shipping with a standard accessory bundle alongside the complete Omni station. It is registered in the Ecovacs spare-parts system under the Ecovacs DLX23 hardware designator, which is the platform code under which the robot body appears in regional maintenance documentation and dealer spare-parts catalogues. Both the Deebot T20 Omni consumer name and the DLX23 hardware designator refer to the same robot hardware. The full maintenance schedule in this guide applies without modification to either designation, and replacement parts ordered under either name are functionally interchangeable.
Deebot T20 Pro, Deebot T20 Pro Plus, and Ecovacs DLX53
The Deebot T20 Pro extends the standard T20 Omni accessory bundle with a richer in-box configuration, typically including a spare filter or an additional pair of mop pads to cover the first replacement interval. The Deebot T20 Pro Plus extends the Pro configuration further, with additional bundled consumables and in some markets a finished dock cover option available at the point of retail. Both the T20 Pro and T20 Pro Plus appear in the Ecovacs hardware catalogue under the Ecovacs DLX53 platform designator. The robot chassis, the consumables specification, and all service intervals are identical to those of the T20 Omni and DLX23. The richer accessory bundles of the Pro and Pro Plus tiers mean many owners of these models begin with a stock of spares already in hand, which typically supports correct replacement intervals through the first year of ownership without a separate parts order.
Deebot T20 Max Omni
The Deebot T20 Max Omni is the upper-tier T20 configuration offered in most markets, typically sold with the most comprehensive retail accessory set in the range. It is most commonly deployed in larger homes that require longer and more frequent daily sessions. Because run time on this model is typically greater than on the standard T20 Omni or T20e Omni, the two-month filter interval and the two-month mop-pad inspection interval are the practical operating targets for this variant rather than the upper limit of the recommended range. Dock maintenance cadences, particularly the dirty-water tank rinse, are also reached more quickly in a high-usage deployment and should be treated as minimum intervals rather than approximate guidelines. Scheduling the first pad inspection at six weeks from installation rather than two months is a practical approach for Max Omni owners running full-home mop cycles daily.
Deebot T20e Omni
The Deebot T20e Omni is the entry-point T20 configuration, sold with a narrower initial accessory bundle than the Pro or Max Omni variants. Despite the leaner out-of-box contents, the consumables specification is unchanged from the rest of the T20 range. The same HEPA filter, the same floating rubber main brush, the same OZMO Turbo pad specification, and the same 2.5-litre dock dustbag apply to the T20e Omni as to every other named robot model in this series. The full maintenance schedule in this guide is directly applicable without adjustment. Owners of the T20e Omni should expect to source a first set of replacement consumables independently at around the two-month mark given that the entry-level bundle typically does not include spare parts beyond the initial set fitted at purchase. The dock dustbag is the item owners most often need to source separately first, since the entry-level bundle frequently ships without a spare bag: the Deebot T20e Omni dustbag can be ordered on its own rather than as part of the full Maintenance Set.
T20 Omni Station (CH2232)
The T20 Omni Station (CH2232) is the dock unit paired with all T20 robot variants and carries its own maintenance obligations that are as consequential for sustained floor-cleaning quality as the robot consumables themselves. The station contains the water heating element for the 55°C pad wash, the hot-air drying fan assembly, the dirty-water and clean-water tanks, the auto-empty dustbag compartment, and the spray nozzles. Owners who treat the station as a background component rather than as a first-class service item encounter declining pad wash quality as nozzles accumulate limescale, progressive dock odour from unrinsed tank residue, and auto-empty failures that trace back to the station hardware. The CH2232 designator is used in Ecovacs service documentation and some regional parts catalogues to identify the station unit when ordering dock-specific components such as the dirty-water tank assembly or the spray nozzle set.
