Hobot 2S Window Cleaning Robot – Dual Ultrasonic Spray, App Control, 72 W

The Hobot 2S (HOBOT-2S) is a square window cleaning robot that holds itself on the glass by vacuum suction. Two ultrasonic nozzles spray a fine water mist while it works across the window, and you control it from the app or the remote.

Key features

• Dual ultrasonic spray: two nozzles turn water into a 15 micrometre mist to dampen the glass as the robot cleans.
• AI path planning: the robot cleans in linear, zigzag and N-shaped patterns and adjusts its route as it goes.
• Two water tanks: two replaceable 26 ml tanks feed the spray nozzles.
• Backup battery: a built-in UPS battery keeps the robot held on the glass for 20 minutes if the power is cut.
• App and remote: control it over Bluetooth from the app or with the remote, with voice alerts and over-the-air firmware updates.
• Edge sensors: edge-leakage sensors detect the edge of the glass.

Size and fit

The robot measures 24 x 24 x 8.6 cm and weighs 1.3 kg. It works on windows of at least 40 x 40 cm and comes with a safety rope rated for 200 kg.
