The cheapest way into the W2S line, with the same suction claim and edge scrubber as the Omni. KultureGeek found it cleaned indoor glass well in one pass but noted you manage the cord yourself. Check what is in the box before buying, since Ecovacs US does not list the contents.

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.
