Fmart W7
Score: 77/100Rankings
The FMART W7 combines 4000 Pa suction with dual-sided ultrasonic spray and AI navigation for reliable window cleaning. Its battery runtime varies and reliance on a power cord can restrict fully cordless use. Suited for homeowners and offices with multiple framed windows.
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 consider the W7 a solid, no-nonsense window-cleaning robot that delivers strong suction and effective dual-spray cleaning. Its AI-driven navigation and safety tether are praised, but the device is seen as an incremental upgrade rather than a breakthrough, especially on very large panes where runtime and cordless freedom become limiting factors.
Everyday users appreciate the ease of app control, the streak-free results, and the safety features that let them clean high-rise glass without ladders. Recurring complaints focus on the limited battery life, the need to replace consumable pads and nozzles, and occasional assembly errors that affect performance.
