- Our score: not scored yet
- Price: $600 (checked Oct 26, 2026)
- Status: on sale
- Best for: large glass doors and picture windows
- Skip if: your windows are small or split into many panes
- HTML version: https://robotsforthat.com/robot/ecovacs-winbot-w2s-omni/

## Verdict

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.

## Pros

- 8,000 Pa suction claim
- Station stores the robot and manages the cable
- TruEdge edge scrubber
- Handles frameless glass

## Cons

- Loud during use per Teltarif
- Can drip onto the windowsill
- High price for the size of the tank
