17. Q: Why can't the Xiaomi Truclean W30 Pro Wet Dry Vacuum start self-cleaning?
A: The following conditions need to be met for the Xiaomi Truclean W30 Pro Wet Dry Vacuum to activate self-cleaning:
1. The main unit must be on the charging dock, the base must be powered, and the unit must be charging;

A: Use the included cleaning brush of the Xiaomi Truclean W30 Pro Wet Dry Vacuum to remove large debris. Then place the main unit on the Self-cleaning Charging Dock and activate self-cleaning and drying.
Note:
Do not rinse the brush head directly with running water or a showerhead.

19. Q: Is it normal for the water output of the Xiaomi Truclean W30 Pro Wet Dry Vacuum to be large at the beginning and then smaller afterward?
A: Yes, this is normal.
At startup, the water flow is intentionally higher for about 10 seconds to quickly wet the roller brush of the Xiaomi Truclean W30 Pro Wet Dry Vacuum. It then decreases to a steady low flow suitable for cleaning without leaving water marks.

20. Q: Why are there no water marks when pushing the Xiaomi Truclean W30 Pro Wet Dry Vacuum forward, but a thin water film appears when pulling it back?
A: When pushing forward, the roller brush leads, and the squeegee and suction port follow, quickly removing water. When pulling back, the squeegee is in front, so the roller brush leaves a thin film of water behind, which dries naturally within 60 seconds.
To reduce this, use a zigzag cleaning pattern or activate water suction mode after cleaning.

21. Q: What to do if the Xiaomi Truclean W30 Pro Wet Dry Vacuum roller brush occasionally reports "brush entanglement" when in use?
A: The reasons for the roller brush of the Xiaomi Truclean W30 Pro Wet Dry Vacuum to be entangled are as follows:
This happens because the new roller brush has long fluffy fibers. When the clean water tank is full, the added weight reduces clearance between the tank and roller brush , causing slight contact when the roller brush is still dry.
The solutions are as follows:
In the event of a malfunction, simply power the device off and on in normal. The initial strong water flow will moisten the roller brush, and once the brush fibers soften and flatten slightly, normal floor cleaning can proceed. You can also perform a self-cleaning cycle.
Note:
The reduction in fluffiness of the brush after being moistened will not affect the cleaning performance.

22. Q: What to do if the foam comes out from both ends of the roller during self-cleaning on the Xiaomi Truclean W30 Pro Wet Dry Vacuum?
A: If the foam comes out from both ends of the roller during self-cleaning on the Xiaomi Truclean W30 Pro Wet Dry Vacuum, the reasons are as follows:
1. Use of non-official cleaners (like dish soap or high-foam liquids);
2. Excessive use of official cleaner (not diluted properly);
3. Residual cleaning agents (e.g., dish soap, floor cleaner, body wash) on the floor.
The solutions are as follows:
1. Dilute cleaning agent according to official instructions;
2. Rinse the clean water tank using clean water-shake to remove residue;
3. Rinse the roller brush thoroughly under running water;
4. Reassemble and run self-cleaning using only clean water. After bubbles stop, resume with correct cleaner ratio.

23. Q: Why does the brush of the Xiaomi Truclean W30 Pro Wet Dry Vacuum get tangled with long hair?
A: When the Xiaomi Truclean W30 Pro Wet Dry Vacuum’s soft roller brush with high-toughness soft bristles is used, it can effectively reach into gaps to clean dirt. However, it can still get tangled with hair, especially long hair.
Fortunately, resolving this is very simple, just remove the roller brush and use the small cutter on the cleaning brush to lift and remove the hair. Of course, we also recommend doing a preliminary cleanup of the floor before using the device.
