Tosima W2
Score: 71/100Rankings

The Tosima W2 is a compact, AI-driven window-cleaning robot offering 3800Pa suction and 5 m safety rope for safe high-rise use. Its short 20-25 minute runtime and lack of app control limit longer or integrated cleaning sessions. Best for users needing quick, hands-free spot cleaning on medium-size panes.

The CHOVERY CL3 is an ultra-lightweight AI-driven window cleaner with dual-side spray and up to 30 minutes of cordless operation. Its corded primary design and modest battery backup limit freedom on large jobs. Ideal for users who need a portable, safe solution for windows, mirrors or tiles up to 30 m².

Professional reviewers and editors commend the CHOVERY CL3 for its ultra-lightweight construction, strong suction and AI-based navigation, noting that these features deliver secure, efficient cleaning on large vertical surfaces while the safety rope and battery backup add confidence. However, they also caution that the device remains fundamentally cord-powered, and the water spray output may fall short for very large jobs.
Everyday users love the robot's light weight and ease of handling, praising the dual spray for streak-free results and the reliable no-slip performance on big windows. Recurring complaints focus on the corded design limiting freedom of movement and the relatively short 30 minute battery backup, as well as the need to refill the spray bottle frequently.
