Smart dirt level display

The washer will detect the floor dirt level in real time. When the floor or the roller brusher is found to be dirty and the screen animation shows a yellow background, and you are recommended to clean the current location repeatedly. If the background remains yellow when the floor is already clean, you should start self-cleaning.

Suction Mode: Used to remove water buildup on the floor.

Quiet Mode: Suitable for relatively clean floors to deliver a noise-free experience and secure a longer battery life to clean more floors.

High dirt level: When the floor or the roller brush is found to be dirty and the screen animation shows a red background, and you are recommended to switch to Turbo Mode to clean the current location. If the background remains red when the floor is already clean, you should start self-cleaning as prompted or manually clean the pipe and the roller brush.

Low Areas Mode

When the angle between the handle and the floor is below 25°, the vacuum mop will automatically switch to the Low Areas Mode. As such areas are generally filled with lots of hairs, dust, and flu, the machine will intelligently adjust the suction power to avoid dust floating around.

Note: DO NOT lay the machine horizontally when not in use to prevent backflow of sewage and damage to the machine.

About self-cleaning and drying

•When self-cleaning starts, the vacuum mop will intelligently select the right cleaning strategy based on the dirt level, including high-temperature roller brush disinfection and cleaning, pipe disinfection and cleaning, and intensive disinfection. •When iron drying starts, the vacuum mop will iron dry the roller brush and hot-air dry the pipe and filter by default.

Note: Self-cleaning intelligently lasts for 3-5 minutes depending on the dirt level and clean water volume.

Note: Iron drying lasts for at least 30 minutes, and the vacuum intelligently adjusts the time based on the roller brush humidity and wearing.

Warning: DO NOT touch the heating plate during or shortly after iron dying, otherwise, you may get burned.
