Score: 81/100
Tosima W5
Score: 68/100Rankings

The Hobot-298 is an AI-driven window cleaning robot that excels on large, frameless glass with ultrasonic mist spray and fast cleaning speed. Its small water-tank capacity and the need for a safety rope limit convenience on smaller panes. Best suited for homeowners with big windows who prioritize speed and streak-free results.

The Tosima W5 is a compact, battery-powered window-cleaning robot featuring 3800Pa suction and dual-direction auto-spray. Its short 25-minute backup time and reliance on a power tether limit autonomous operation. Ideal for users who value hands-free cleaning on vertical surfaces and prioritize safety features.

Professional reviewers consider the Hobot-298 an advanced, AI-driven window cleaning robot that excels on large, frameless glass surfaces. They commend its ultrasonic mist spray, fast cleaning speed, and low-noise motor, while noting that optimal performance still depends on using a detergent and that the device is less suited for small panes.
Everyday users praise the robot for making large-window cleaning effortless, quiet, and streak-free thanks to the mist technology. Common complaints revolve around the need for detergent on tough grime, the effort required to set up the safety rope, limited water-tank capacity, and occasional app or remote connectivity issues.

Professional content is limited to promotional videos and product pages, but reviewers consistently emphasize the robot’s dual‑spray system, AI‑driven navigation and robust safety features as standout strengths. The main criticism from experts is the short 25‑minute battery backup and the absence of app‑based control, which may put it behind more autonomous competitors.
There are no direct consumer reviews, ratings, or testimonials in the available sources, so everyday user sentiment is largely undocumented. Promotional material suggests users would appreciate hands‑free, streak‑free cleaning on smooth surfaces, but no recurring praise or complaints can be confirmed.
