Our Verdict: The reciprocating polish technology genuinely outcleans circular-pad robots — the best scrubbing action in the category.

The HOBOT S7 Pro is the latest flagship from Taiwan-based HOBOT, the pioneer of window cleaning robots. It combines 4,800Pa suction with a 40% larger suction ring than previous models for an exceptionally secure grip on any glass surface.

Reciprocating Polish Technology

Rather than simply wiping, the S7 Pro uses dual mop pads that reciprocate at 600 strokes per minute with a 4mm stroke length. This back-and-forth scrubbing action is far more effective at removing stubborn dirt, hard water stains, and fingerprints than the circular motion used by competitors.

Ultrasonic Precision

Dual 15nm ultrasonic spray nozzles atomise cleaning solution into an ultra-fine mist, loosening dirt without oversaturating the glass. The result is streak-free cleaning at a speed of 2.6 min/m².
