Not sure which one fits your windows?
3 quick questions, then only the robots that fit.
ECOVACS sells eight WINBOT window cleaning robots on its US store that we list, from the palm-sized WINBOT mini to the W3 OMNI, whose station washes its own cleaning pads. Here they are side by side on the specs ECOVACS publishes, so you can match one to your window sizes, how much glass you have and whether you want a station.
Side by side
| Model | Suction (published) | Station | Smallest window | Power-cut hold | Spray |
|---|---|---|---|---|---|
| ECOVACS WINBOT W3 OMNI | 3,300Pa while moving | Washes the pads | Not stated | Not stated | Three nozzles, wide-angle |
| ECOVACS WINBOT W2S PRO OMNI | 10,000Pa | Portable, 18 ft rope | 11.8 x 15.7 in | Not stated | Three nozzles, wide-angle |
| ECOVACS WINBOT W2S OMNI | 8,000Pa | Carry station, cable reel | 11.8 x 15.7 in | 30 minutes | Automatic, 2.7 fl oz tank |
| ECOVACS WINBOT W2 PRO OMNI | 5,500Pa (plus or minus 500Pa) | Portable, cable reel | 11.8 x 15.7 in | 30 minutes | Automatic, 2.0 fl oz tank |
| ECOVACS WINBOT W2S PRO | 10,000Pa | None listed | 11.8 x 15.7 in | Over 30 minutes | Three nozzles, wide-angle |
| ECOVACS WINBOT W2S | 8,000Pa | None | 11.8 x 15.7 in | 30 minutes | Three nozzles, wide-angle |
| ECOVACS WINBOT MINI 2 | 8,000Pa maximum | None listed | 9.8 x 9.8 in | 30 minutes | Ultrasonic, four nozzles |
| ECOVACS WINBOT mini | 7,500Pa | None | 8.7 x 9.8 in | 30 minutes | Ultrasonic, 2.0 fl oz tank |
Suction is ECOVACS’s own figure. The W3 OMNI’s is measured while moving and the MINI 2’s 8,000Pa is its maximum (3,400Pa while moving), so these aren’t measured the same way. Power-cut hold is how long the robot stays on the glass if the power goes out. Specs come from each model’s ecovacs.com/us product page, read Oct 23 and 24, 2026. Where only metric is published, the US figure on this page is our conversion, rounded, with the published figure in brackets on the product pages.
The eight WINBOTs
ECOVACS WINBOT W3 OMNI
The W3 OMNI’s station washes the cleaning pads in about a minute, using 16 high-pressure nozzles and four scrub discs. On the glass it lists 3,300Pa of suction while moving, a three-nozzle wide-angle spray with a 2.7 fl oz (80 ml) tank, TruEdge with Smart Lift for edges and corners, and WIN-SLAM 5.0 navigation with seven modes: Edge, Fast, Heavy-Duty, Spot, Deep, Thorough and Zone. It runs plugged in or on battery, with a two-in-one power and safety cable.
Suits: homes with lots of glass, where washing pads by hand gets old fast.
Worth knowing: ECOVACS doesn’t state how long it holds on if the power cuts out, and its spec table lists six spray nozzles where its feature list says three.

Buy at ECOVACS Full specificationsHow to choose
- Station or not. Four of the eight come with a station: the W3 OMNI (washes the pads), the W2S PRO OMNI, the W2S OMNI and the W2 PRO OMNI (carry stations with cable management and a safety rope). The W2S PRO, W2S, MINI 2 and mini don’t.
- Window size. For small panes, the mini (from 8.7 x 9.8 in) and MINI 2 (from 9.8 x 9.8 in). The W2 and W2S models list 11.8 x 15.7 in as their smallest window.
- Sloped glass. ECOVACS lists the W2S and W2S OMNI for glass tilted up to 45°. It doesn’t publish a tilt figure for the others.
- Suction. The W2S PRO and W2S PRO OMNI list the most, 10,000Pa. Compare the W3 OMNI and MINI 2 with care: ECOVACS quotes a while-moving figure for them.
- Safety. Use the safety rope on any window above ground level. Most of these hold on for 30 minutes if the power cuts out; ECOVACS doesn’t state a figure for the W3 OMNI or W2S PRO OMNI.
