Ecovacs Winbot W2S Omni
Ecovacs window robot with a portable battery station for big glass
Researched by Riley Hart · updated Oct 26, 2026
SCORED
We started tracking this price on Oct 26, 2026 and have not found a past sale price yet, so we cannot say if $600 is a good deal. Black Friday is Nov 27, 2026, 31 days away, when robots in this category usually get their biggest cuts. Get a price drop alert.
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.
Best for: large glass doors and picture windows. Skip if: your windows are small or split into many panes.
