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.

A good pick for people with large panes who want a station that holds the battery and reels in the cable. Teltarif found it cleaned everyday dirt evenly but left light lines after one pass and dripped on the sill. Skip it for small or barred windows, where it saves little time.
