  • ๐Ÿšซ Mineral water (even still) - due to high hardness.
  • ๐Ÿšซ Soap solutions or detergents (except special ones for vacuum cleaners Xiaomi).
  • ๐Ÿšซ Hot water โ€“ can warp plastic tank parts.

If the vacuum cleaner does not spray water after filling, check:

  1. Air in the system (shake the tank to blow the plug).

7. Frequent questions and problem-solving

We have collected answers to the most popular questions of users of Xiaomi vacuum cleaners with the wash function.

The vacuum cleaner doesn't spray water, even though the tank is full.
The reasons may be as follows: ๐Ÿ”Œ The tank is not tightly closed - check if you hear a click when installing. ๐ŸงŠ Frozen water (relevant for cold rooms) - let the vacuum cleaner heat up to room temperature. ๐Ÿ”ง Clogging sprayers - clean them with a needle or compressed air. ๐Ÿ“ฑ Firmware failure - restart the vacuum cleaner (hold the power button for 10 seconds). If nothing helps, contact the service center - possible failure of the pump.
Can I pour hot water for better laundering?
No! Hot water (over 40)ยฐC) can: Deform the plastic tank, damage the O-rings, disable the water level sensor (electronically controlled models) Use room temperature water (20-25)ยฐC) To remove persistent contaminants, it is better to increase cleaning time or use a branded detergent.
How often should I change the water in the tank?
Depends on the intensity of use: ๐Ÿ  Daily cleaning: drain water after each use and flush the tank. ๐Ÿ“… Cleaning 2-3 times a week: it is enough to change the water once every 3 days, but dry the tank after each cleaning. ๐Ÿšซ Leave water for a week or more: this will lead to mold and bacteria.
The vacuum cleaner started smelling damp. How do you eliminate the smell?
The unpleasant smell is caused by the bacterial proliferation in the tank. To eliminate it, wash the tank with a solution of vinegar (1:3 with water) or hydrogen peroxide (3%). Dry all the parts in the air (you can use a dryer in cold mode). Place a bag of silica gel (from a shoebox) in the tank to absorb moisture. Next cleaning, add 1-2 drops of tea tree essential oil (natural antiseptic). If the smell remains, check the hoses and filters - perhaps mold appeared there.
Can you use a vacuum cleaner without water, only for dry cleaning?
Yes, but with reservations: โœ… Robot Vacuum-Mop โ€“ you can turn off the wash function in the application and use only a brush. โš ๏ธ Vertical vacuum cleaners (Dreame) W10) โ€” It is not recommended to include without water in steam harvesting mode, since the heater can overheat. ๐Ÿ”‹ For all models: if the water tank is removable, it can simply not be installed.

To avoid mistakes and extend the life of your Xiaomi vacuum cleaner, follow this algorithm:

Use only distilled or boiled water|Check the integrity of the sealing rings|Do not exceed the mark MAX tank-house|Make sure the tank is tightly closed (click!)|Select the correct mode in the application (Mopping/Steam)|After cleaning, drain the water and dry the tank-->
