Product Description

HOBOT-388 is a glass-cleaning robot with a vacuum motor inside that generates strong suction power to allow it to stay attached to the glass. The new patented invention carries a detachable water tank along with an ultrasonic spray nozzle which nebulizes water to mists then sprays it evenly on glass simulating the effect of human breath on the glass. HOBOT-388 has two specially-design cleaning wheels that can freely move on the glass, and even walls. The screw-in DC power jack design can avoid losing power during usage, while the embedded UPS (Uninterrupted Power System) can prevent the robot from falling off the window for 20 minutes even in case lost power; ultimately, the safety rope can endure the impact force up to 200kg to catch any fall. The reusable lint-free Microfiber cloth is used on both cleaning wheels to attain superior glass cleaning. HOBOT has AI Technology that can calculate paths, auto-detect window edges, and auto-clean entire window. Beside equipped remote control, HOBOT-388 can be controlled by iOS and Android devices via blue tooth connection.
