Ecovacs Winbot W2 Omni
Score: 82/100Rankings
The ECOVACS Winbot W2 Omni is a portable window-cleaning robot with industry-leading suction and up to 110 minutes of untethered runtime. Its heavy system weight, variable runtime claims and long charging time are notable trade-offs. Best suited for tall-window homeowners who need safe, outdoor-capable cleaning.
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.
Professional reviewers commend the W2 PRO OMNI for its industry-leading safety architecture, long untethered battery life and the ability to clean large glass areas quickly and quietly. The portable OMNI station is highlighted as a differentiator that enables true outdoor use, while the robot matches the performance of the larger W2 PRO model but with added portability and a slightly quieter acoustic profile.
Everyday users consistently praise the robot's ease of use, reliable cleaning results and the convenience of cleaning high or outdoor windows without ladders. The long battery life and quiet operation are frequently mentioned as positives, while a few customers note the heavy package and occasional variability in runtime as minor drawbacks.
