A strong value now that Ecovacs lists it at $399 with the station. TechRadar got very dirty windows clean in one cycle and the robot never lost grip. Corners still need a hand wipe, and newer W2S models claim more suction.

An older but still sold design from a specialist window robot maker, now priced between the Mova N1 and the Ecovacs Omni models. Independent testing is thin and dated, and its small twin tanks and 20 minute backup trail newer rivals. Consider it mainly if you want a Hobot with frameless edge detection from a US store.
