of "Let robots serve everyone".

【Easy to Use】The machine needs to be

connected to the power supply. Just press a button to turn it on, and the two

wheels of the window cleaner can move freely on the surface of the window or

wall. If the red light flashes, you need to check whether the power supply is

correctly connected.

【Automatic Water Spraying】This window cleaner adopts an

ultrasonic nozzle design. You no longer need to spray water manually, and you

can clean the windows more thoroughly and cleanly. For every 1.4 ml of water,

1 square meter can be cleaned.

【Brushless Motor】The upgraded brushless motor

has a high suction power to firmly fix the window cleaner on the vertical

glass surface for high - speed and high - pressure cleaning. Don't worry about

it falling during operation.

【Efficient Cleaning】The motor of the vacuum

cleaner works with a microfiber cleaning cloth, which completely wraps around

during rotation and wipes away dust without damaging the glass surface. Stains

won't spread, and the windows will be cleaner. It comes with 10 microfiber

cleaning pads (5 pairs), which are replaceable and machine - washable, saving

money and being environmentally friendly.

【Safety Protection】In case of a power outage, the

built - in backup battery will automatically activate and keep the cleaner on

the window for 20 - 25 minutes. An alarm also reminds you that you can connect

a professional 150 - kg load - bearing climbing safety rope to the robot to

provide a third layer of safety protection.
