Feature: 1. Vacuum Motor: The robot uses a built in vacuum motor to help it suck in wind, generating 2800PA strong suction with a sound level of 65dB, and a double spiral cleaning head with a microfibre cleaning cloth, which can walk freely on vertical glass surfaces. 2. Edge Detection: Built in intelligent AI technology, the window cleaning robot can detect window frames and obstacles and automatically adjust its direction. It makes window cleaning easier without your manual intervention. 3. Intelligent: The window cleaner intelligently calculates the path and controls the machine by remote control to clean the entire window automatically. Whether it is a window in a tall building or a hard to get to glass surfaces, it can be fully cleaned. 4. Anti Falling: The cleaning robot also features suction preservation, which can run for up to 25 minutes after the unit has been switched off, ensuring that the robot is firmly attached to the window and preventing it from falling out of the window and sounding an alarm in time. 5. Multifunctional: It has three functions of automatic cleaning mode, manual cleaning mode and water spray to meet different cleaning needs, making the cleaning process more flexible and convenient, so that you can enjoy more fun and save more time when wiping windows.
