- Spray
- Three nozzle spray

- 3,000 mAh battery
- Frameless
- Supported
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.

- Yes
An older but still sold design from a specialist window robot maker, now priced between the Mova N1 and the Ecovacs Omni models. Independent testing is thin and dated, and its small twin tanks and 20 minute backup trail newer rivals. Consider it mainly if you want a Hobot with frameless edge detection from a US store.
