Dreame’s global premium square-mop platform spans three related lines that share one consumable family: the first-generation Dreame L10 Ultra, the second-generation Dreame L10s Ultra and Dreame L10s Ultra SE, and the flagship Dreame X10 Ultra. When any of these robots returns to the dock trailing faint streaks across hard floors, produces a stale smell from the mop-wash station, or triggers a brush-error alert sooner than expected, the cause is almost always a consumable past its service interval. This guide sets out the full maintenance schedule and explains where each model in the L10 and X10 Ultra family diverges in its upkeep.
Why Dreame L10 Ultra, L10s Ultra and X10 Ultra robots need more frequent maintenance
A liftable mop plate that elevates on carpet but keeps the pad in constant contact on hard floors
Every model in this family uses a flat mop pad that lifts automatically when the robot transitions from hard floor to carpet, then lowers back to cleaning position when it returns to hard floor. This lift mechanism is the defining feature of the L10 and X10 platform and the reason it can clean mixed-floor homes without manual pad removal. The mechanism introduces a pivot point and a lift motor that require periodic attention, as the underside of the mop arm accumulates mineral deposits from damp pad contact over months of operation. On the Dreame L10s Ultra and Dreame X10 Ultra, the auto-lift feature means the pad is lowered precisely on every cleaning pass, which maintains consistent pressure and distributes pad wear more evenly than a fixed-height system, supporting the longer end of the one-to-three-month replacement window.
A rubber main brush that resists hair wrap but compacts fine hair in end-cap bearings
All models from the Dreame L10 Ultra to the Dreame X10 Ultra use a one-piece rubber roller. The rubber construction resists the tight hair coils that cause brush stall on bristle-type brushes, but fine hair still migrates to the end-cap bearings at both shaft ends and compacts there over time. Once packed in the bearings, that hair applies a continuous drag that the brush motor absorbs as additional current draw. Left unchecked, this shortens motor bearing life and eventually triggers an over-current brush error. Every model benefits from an end-cap inspection every one to two weeks, and the rubber fins themselves need replacement after five to seven months of daily use when they visibly flatten and lose their edge-sweeping profile.
Multifunctional dock stations introduce additional maintenance points beyond the robot itself
The Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra dock stations wash the mop pad, refill the clean-water tank automatically, empty the onboard dustbin into a sealed bag, and apply hot-air drying after every wash cycle. Each of those functions introduces its own maintenance obligation. The wash nozzles accumulate mineral scale in hard-water regions. The dirty-water tank fills with residue-laden water after every run and develops odour within two to three days if not emptied. The hot-air dryer vent grilles at the base of the dock collect lint and need a periodic wipe to maintain airflow. The Dreame L10 Ultra‘s simpler dock requires less dock-side attention overall, but the dirty-water tank emptying obligation remains the same across all generations.

First generation — Dreame L10 Ultra (5,300 Pa)
The Dreame L10 Ultra is the platform’s first generation. Running at 5,300 Pa with a flat liftable mop and a mop-wash dock that washes pads and applies fan-assisted drying, it operates with less filter loading pressure than the second-generation models. This translates into a four-to-six-month filter replacement window, the longest on the platform. The L10 Ultra does not include a sealed auto-empty dustbag on all regional configurations; on variants without the bag dock, the onboard dustbin is emptied manually and the dustbag interval does not apply. Regional OEM code Dreame RLS5L is the market-specific identifier for this generation and follows the same service schedule in every respect.
Second generation — Dreame L10s Ultra and L10s Ultra SE (7,000 Pa)
The Dreame L10s Ultra and Dreame L10s Ultra SE represent the second generation of this platform. Both raise suction to 7,000 Pa and add a fully multifunctional dock station with automatic dustbin emptying, clean-water auto-refill, and hot-air mop drying. The increased suction shortens the filter replacement window to three to five months and the sealed dustbag needs replacement every two to four months. The additional dock functions introduce two further monthly maintenance tasks: nozzle descaling and dryer-vent lint wipe. Regional OEM codes Dreame RLS6L and Dreame RLS6LADC correspond to L10s Ultra platform variants and follow the identical consumable set and maintenance schedule without modification.
Replacement parts and service intervals
Rubber main brush roll
Inspect every one to two weeks. Remove the roll and clear any wrapped hair along its full length with scissors or a seam ripper, then check the end-cap bearings at both shaft ends for compacted fine hair and clear with a toothpick. The roll should spin freely by hand before reinstalling. Dreame’s platform guidance recommends replacement every six to twelve months. The lower end of that window applies in pet households and homes with long-haired occupants; the upper end is realistic in single-occupancy flats with minimal shedding. On the 7,000 Pa models, the higher continuous suction pressure flattens the rubber fins faster and draws the replacement interval toward six months under daily use. Reduced carpet pick-up despite a thorough cleaning session is the most reliable end-of-life indicator.
HEPA filter
Tap the filter firmly on all four sides over a waste bin every one to two weeks to dislodge accumulated debris. Do not wash the filter with water unless the packaging specifically confirms it is washable; washing degrades the HEPA medium’s pleating even when the filter looks intact after drying. Replacement intervals follow the suction tier: every four to six months on the Dreame L10 Ultra at 5,300 Pa, and every three to five months on the Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra at 7,000 Pa. A consistent mid-grey colour across the filter face is the visual signal to replace regardless of elapsed weeks.
Side brush
Inspect the side brush mounting post every week. Hair and long fibres accumulate at the base of the stem and progressively load the small motor that drives the brush. Clear any wrapped material with fine scissors or a toothpick, being careful not to pull hard on the flexible arm. Replace every three to six months, sooner in pet households. A bent or asymmetrical brush produces uneven reach along walls and into corners and should be replaced immediately rather than straightened; the flexible material takes a permanent set once deformed. Dreame’s manufacturer guidance across this platform aligns with a three-to-six-month replacement window, consistent with observed wear in typical residential use.
Mop pads
The dock’s wash cycle handles daily hygiene but does not reverse physical degradation of the pad fibre over time. Dreame’s maintenance guidance recommends replacement every one to three months under daily use. The flat liftable pad design used across the Dreame L10 Ultra, Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra distributes pressure evenly across the pad surface, which supports the longer end of the manufacturer window in moderate-traffic homes. Inspect at eight weeks. A pad that feels stiff after a wash cycle or no longer fully absorbs a splash of water on its surface has passed its effective service life and should be replaced.
Dock dustbag
The sealed auto-empty dustbag on the Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra captures material transferred from the onboard dustbin after every run. Dreame’s guidance puts the replacement interval at every two to four months, or approximately seventy-five days of daily use. A full bag causes the next auto-empty cycle to fail mid-transfer and leaves the onboard dustbin unable to accept new debris on the following run. The sealed design prevents fine dust from escaping into the room during replacement, which matters in homes where a household member has pollen or pet-dander sensitivity. On the Dreame L10 Ultra, the dustbag interval applies only to configurations that include an auto-empty dock; on variants where the onboard dustbin is emptied manually, this interval does not apply.
Dock dirty-water tank and spray nozzles
Empty and rinse the dirty-water tank every two to three days across all models in this family. After rinsing with fresh water, wipe the interior with a cloth and allow it to air-dry briefly before reinstalling; a wet tank reintroduces the bacterial growth the rinse was meant to remove. In hard-water regions, soak the tank in a solution of equal parts white vinegar and water for thirty minutes once a month to dissolve mineral build-up. On the Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra, also wipe the dock’s mop-wash spray nozzles monthly; scale build-up on these nozzles causes uneven water delivery to the pad and is the primary cause of streaking on hard floors after an otherwise normal dock cycle. Increase that frequency to every two to three weeks in hard-water regions.
Sensor windows and lidar turret
All models on this platform use a rotating LDS lidar turret mounted on top of the chassis, keeping the navigation sensor well above floor-level dust. A dry microfibre wipe of the rotating turret window every two to four weeks is enough to maintain reliable laser ranging. On models with an AI-enabled forward-facing camera, wipe the camera window weekly on the same schedule as the underside cliff sensors. Smudged sensors cause unnecessary detours around clear floor space and in persistent cases prevent the robot from completing its cleaning map. Do not use cleaning solvents on the lidar window; a dry cloth is the only recommended method.
Battery
The lithium-ion battery pack inside the Dreame L10 Ultra, Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra is sealed within the chassis and operates reliably for eighteen to twenty-four months under daily use before remaining charge capacity begins to affect cleaning coverage noticeably. The earliest reliable signal is the robot returning to dock mid-run more frequently than it did when new, even after completing a full overnight charge. Charge contacts on the underside of the robot and the corresponding dock pins should be wiped with a dry cloth every four to six weeks; oxidised contacts reduce charging efficiency and can cause the robot to report a full charge state while actual stored capacity is lower than the indicator suggests. If the robot no longer completes its typical cleaning zone on a single charge after confirming the contacts are clean and the charging cycle ran fully, the battery has reached the end of its serviceable life and warrants replacement.

Common problems and their maintenance causes
Suction noticeably weaker than it used to be
The HEPA filter is saturated. Remove it and inspect; if the medium has shifted from white to a consistent grey, replace it regardless of elapsed weeks. If the filter still looks clean, inspect the suction inlet at the top of the onboard dustbin for a caked-dust blockage and check the main brush chamber for debris packed behind the roll. On the Dreame L10s Ultra and Dreame X10 Ultra, a partially failed auto-empty cycle can also leave the onboard bin half-full after docking; the robot treats this as normal but the reduced dustbin capacity limits debris capture on the following run.
Mop pads returning with streaks or damp patches on hard floors
Work through three causes in order. First, the dock spray nozzles have partial mineral build-up and are delivering uneven water to the pad during the wash cycle; wipe the nozzles and, if scale is visible, descale with dilute citric acid. Second, the pad fibre has reached end-of-life and is redistributing residue rather than lifting it; replace the pad. Third, on the Dreame L10 Ultra, confirm the pad plate is fully latched to the mop arm; a partially seated plate contacts the floor unevenly and leaves a characteristic irregular streak pattern.
Dirty-water tank smells of stagnant water
The tank was not emptied on the two-to-three-day schedule. Empty it, rinse thoroughly under running water, and wipe the interior dry. If a faint smell persists after a fresh-water rinse, soak the tank in equal parts white vinegar and water for thirty minutes, rinse again, and allow it to air-dry completely before reinstalling. Never reinstall a wet tank; residual moisture promotes the same bacterial growth the rinse was meant to remove.
Auto-empty cycle fails or onboard dustbin remains full after docking
The dustbag has reached capacity, or the transfer chute between the robot’s dustbin and the dock is blocked by fine dust. Replace the bag first; this resolves the problem in most cases. If the cycle still fails with a fresh bag, wipe the docking port at the base of the robot and the port seal on the dock with a dry cloth. Fine dust accumulates around the seal over months of docking cycles and breaks the vacuum needed for clean transfer. On the Dreame L10s Ultra SE, confirm the onboard dustbin is fully seated after any manual inspection; a bin pushed in by one step rather than two will not align with the dock’s suction port.
Brush roll not spinning or brush-error alert appearing
Compacted fine hair in one or both end-cap bearings is applying enough drag to trigger the robot’s over-current protection. Remove the brush roll and inspect the shaft fittings at each end. Clear all wrapped material with a toothpick and wipe the bearing seats clean. The roll should spin freely by hand before reinstalling. If the brush error returns within a few days of cleaning, the bearings have worn past their service life and the roll needs replacing. This is most common on the Dreame X10 Ultra and Dreame L10s Ultra toward the six-month mark in pet households running daily at 7,000 Pa.
Robot detours around clear floor space or will not leave the dock
The lidar turret window or forward-facing camera has accumulated enough contamination to generate false obstacle readings. Wipe the rotating turret window with a dry microfibre cloth and the front camera window on the same pass. If the problem persists, inspect the cliff sensors on the underside of the chassis; a thin film of fine dust can blind these sensors and the robot interprets the blinded sensor as an edge it must avoid, producing erratic pathing or refusal to depart the dock.
Persistent damp smell from mop pads after the dock cycle completes
The pad has reached end-of-life and is retaining moisture even after the dock’s drying phase. On the Dreame L10s Ultra, Dreame L10s Ultra SE, and Dreame X10 Ultra, also check that the dryer vent grilles at the base of the dock are not blocked by lint; a partially blocked vent reduces airflow and leaves pads damp even when the dock reports a successful drying cycle. Clear the vent grilles with a dry brush, then replace the pad if the smell persists after the grilles are confirmed clear.
What consistent maintenance protects over time
Every consumable on this platform influences the wear rate of the next one in the chain. A partially loaded HEPA filter forces the main motor to draw additional current to maintain rated suction, shortening motor bearing life measurably over eighteen to twenty-four months of daily running. A compacted brush end-cap applies the same category of quiet drag. A full dustbag that interrupts the auto-empty cycle leaves debris in the onboard bin that the robot carries into the next session, loading the filter faster than designed. A dirty-water tank left full for four days reintroduces bacterial growth onto freshly washed pads, which then produce the floor streaks that owners read as a mop-pad problem, when the root cause was a tank-emptying task skipped twice in a row. Staying on the schedule across every component keeps each subsystem within its design parameters and extends the practical service life of the robot by a year or more compared with irregular maintenance.
The Plus.Parts® Maintenance Set covers the complete service scope for this platform, including the main brush roll, HEPA filter, side brush, mop pads, and dock dustbag, in a single order. It is a direct functional alternative to the original Dreame RAK11, DRE-L10SU-KIT, and RAK12 consumables with the same fit, dimensions, and filtration specification. Having a complete set on hand removes the risk of extending any single component past its replacement interval while waiting for a part to arrive.
How the L10 Ultra, L10s Ultra and X10 Ultra models differ
The primary maintenance difference across this platform is suction power and dock generation, which together determine filter replacement interval, dustbag frequency, and the additional dock-side cleaning tasks an owner needs to manage. The Dreame L10 Ultra is the first-generation flagship of this line. Running at 5,300 Pa with a flat liftable mop and a mop-wash dock, it occupies the lowest filter-loading tier on the platform with a four-to-six-month replacement window. Its dock washes pads with cool water and applies fan-assisted drying rather than the active hot-air system found on later models. Some regional L10 Ultra configurations include a bag-based auto-empty dock; on those that do not, the onboard dustbin is emptied manually. Regional OEM code Dreame RLS5L is the market-specific product identifier for L10 Ultra platform units and follows every service interval described for the L10 Ultra without any modification.
The Dreame L10s Ultra is the second-generation model. The suction increase to 7,000 Pa shortens the filter window to three to five months and the improved multifunctional dock station adds auto-refill, sealed auto-empty, and hot-air mop drying to the maintenance picture. The L10s Ultra’s auto-lift mop mechanism lifts the pad more precisely on carpet transitions than the L10 Ultra’s earlier system, which contributes to slightly more even pad wear across the surface. Regional codes Dreame RLS6L and Dreame RLS6LADC are L10s Ultra platform variants sold in specific markets; both use the identical consumable set and maintenance schedule as the L10s Ultra. The Dreame L10s Ultra SE is a simplified variant offered in select markets whose dock may omit auto-refill on some configurations, but mop-pad and filter intervals remain identical to the full L10s Ultra.
The Dreame X10 Ultra is the flagship of this consumable family. It matches the L10s Ultra’s 7,000 Pa suction and full multifunctional dock, placing its filter at three to five months and its dustbag at two to four months. Maintenance mirrors the L10s Ultra across every component. The X10 Ultra represents the peak of this platform generation: owners running it daily at full suction should expect to reach the three-month filter mark and the lower dustbag boundary in high-traffic homes, and should budget accordingly when planning their annual consumable order.

My L10s Ultra started leaving streaks on the kitchen tiles after about four months. Replaced the mop pads and the problem was gone immediately, I had underestimated how quickly they wear out with daily mopping.
The roller brush on my X10 Ultra gets tangled with long hair really fast. I check it every ten days now and it’s much quieter when it runs. The tip about not letting the mop pad dry while still attached is one I’ll keep in mind.
After six months with the L10s Ultra SE, the HEPA filter was visibly grey and suction had dropped. Replaced it as part of a full kit and the performance is back to what it was at unboxing.
I was confused about whether the L10 Ultra and L10s Ultra share the same filter, glad the comparison table makes that clear. Ordered the right one this time instead of guessing.
