Our verdict
The W2 PRO is the Winbot without the station, and often the sensible buy. It sprays from six nozzles, plans its route with WIN-SLAM 4.0, resumes after an interruption and returns to where you put it on, detects a frame from 2 mm and an obstacle from 4 mm, and has the edge mode Ecovacs calls an industry first. It holds on with 5,300 Pa in standard mode and 2,800 Pa on the move, compensates the air pressure automatically and keeps its grip for 30 minutes on an internal 3,000 mAh battery if the power fails. You steer it from the app, it gives voice prompts, and at 1.8 kg with a 6 m rope and a 5.5 m cord it is easy to manage. What it lacks is what the OMNI models add: no battery station, so a socket within 6.7 m is a must, a 60 ml tank rated for 40 m², and no claim for the corners.
Pros
- Seven modes on a planned route that resumes after an interruption and returns to start
- Frame detection from 2 mm, obstacle detection from 4 mm
- Pressure compensation and 30 minutes of grip after a power cut
- Omnidirectional app control and voice prompts, 63 dB
- The cheapest W2, with a two-year warranty
Cons
- 5,300 Pa in standard mode, the lowest figure among the Winbots
- Needs a socket: 5.5 m cord plus a 1.2 m mains lead, no battery station
- 60 ml tank rated for 40 m², and no claim for the corners
- Ecovacs states no maximum pane size
Best for
- Ground-floor and interior glass close to a socket
- Anyone who wants the Winbot route planning for the least money
Not recommended for
- Balconies and rooms without a socket, where the OMNI station earns its keep
- Very large panes, where the 60 ml tank runs dry
