A fair buy only at its current discount. Modern Castle found it decent on its own and much better with window cleaner added, but it missed the glass edges. Buyers who want strong edge cleaning should look at newer models.

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.

Hobot 2S
- Appliance Retailer (8.5/10): Reviewer found a streak free finish that is hard to get by hand and called it worth the investment for larger homes. Source
