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 sources describe the W120-DP as a cutting-edge 6th-generation model that pushes the limits of slimness and sensor integration, highlighting its auto-adjusting suction and motorized spray as notable advances over previous generations, though independent testing data is lacking.
