This schedule comes from Dreame’s US-A01 L50 Ultra manual. Confirm the manual and model label for your robot and base station; an English manual does not establish the same hardware or procedure for UK or Canadian units.
Care intervals
| Component | Manufacturer schedule |
|---|---|
| Used-water tank | Clean after each use |
| Dust-box filter | Clean every 2 weeks; replace every 3–6 months |
| Washboard filter | Clean every 1–2 months |
| Dust bag | Replace every 2–4 months |
| Mop pads | Replace every 1–3 months |
| Main brushes | Replace every 6–12 months |
| Dust-box filter and side brush | Replace every 3–6 months |
| Listed sensors, contacts, water-refilling inlet, vents, and signaling area | Clean monthly |
Use the manual’s intervals as a starting schedule. It says actual use and special circumstances may call for earlier care. It does not assign the used-water tank’s after-use interval to the clean-water tank.
Filter and wheel care
Remove the dust box and filter using the manual’s sequence. Tap the filter basket gently, then rinse the box and filter with clean water only. Do not use detergent or scrub the filter with a brush, finger, or sharp object. Dry both parts completely before reinstalling; the manual’s illustration indicates 24 hours.
The omnidirectional wheel may be rinsed, but dry it completely before reinstalling. Do not separate its axle and tire with excessive force. For the robot sensors, charging contacts, station signaling area, and auto-empty vents, use a soft dry cloth; a wet cloth may damage sensitive parts. The used-water tank float moves, so do not force it while cleaning.
Clean the used-water tank after each task and follow the manual’s station steps. Keep hands away from an operating hot-water outlet. Routine care does not authorize opening the pump, motor, battery pack, or electrical sections.
