Roborock QR 798 maintenance set

The Roborock QR 798 is a market-variant SKU of the Qrevo L platform. It delivers 10,000 Pa suction through a single DuoRoller main brush, drives dual spinning mop pads with a 10 mm carpet lift, and docks into a Multifunctional station that runs a three-stage mop wash and auto-empties the robot’s onboard bin into a sealed dust bag. The platform is mechanically identical across all named models and regional codes, so this kit fits every variant.

This set supplies Plus.Parts® direct-fit alternatives to the original Roborock parts QV35A/QV35S MAINTENANCE SET: a rubber main roller brush, four anti-tangle side brushes, four washable filters, four dust bags and four mop pads – 17 parts in all. The sealed dust bag is the consumable owners most often misjudge on this platform. Roborock rates the bag for several weeks, but in practice the auto-empty cycle runs after every session, and compacted fibrous content – pet hair especially – throttles airflow through the transfer port before the bag itself looks full. When the transfer stalls mid-cycle the onboard bin stays loaded, so the next run starts with reduced capacity and debris backs up into the brush chamber. Replace the bag on a fixed three-to-five-week calendar rather than waiting for a full-bag indicator, and shorten that to three weeks in a pet home.

Keep the rest of the service schedule tight alongside the bag. Tap the HEPA filter edges weekly and replace every two months – at 10,000 Pa the element loads faster than on the 5,500 and 7,000 Pa Qrevo tiers. Inspect the DuoRoller brush weekly, clearing wrapped hair and both end-cap bearing holes, and replace every five to seven months. Clear the side-brush posts weekly and swap the pair every three to six months. Inspect the mop pads at eight weeks and replace when the rim nap has worn or persistent discolouration remains after a dock wash. Wipe the dock spray nozzle monthly and the dirty-water tank every two to three days. Clean the LDS port and cliff sensors with a dry cloth weekly. Behind the set is a real team at VacuumReviews.eu, so if the auto-empty cycle stalls or the bin stays loaded, reach out and we will help you trace it to the bag or the transfer port.
