Our verdict
The S7 Pro cleans the way a hand does, only faster: two cloths shuttle back and forth 600 times a minute over a 4 mm stroke, one lifting the dirt the twin ultrasonic nozzles have loosened with a 15-micron mist, the other wiping away the marks on the next row. It holds on with 4,800 Pa over a suction area enlarged by 40%, and the reciprocating mops cut friction enough for 12 cm/s, about 2.6 minutes per square metre. ELB sensors read air leaking at a seal or a frameless edge and bumps against a frame, and it is rated for laminated glass, seamless mirrors and balcony glazing. It runs a zigzag route from a 4 m cord that extends to 8 m, with a 4.5 m rope rated to 230 kgf, 20 minutes of backup, voice prompts you can replace with your own recording, an app and a remote. HOBOT publishes no tank, weight, dimensions, noise or warranty figures, names no radio for the app, offers no feed and no press kit, so no photograph here, and the Wi-Fi flag follows the catalogue's app-control convention.

In detail
Cleaning
It sprays water. It moves at 12 cm/s.
Grip and fit
Suction of 4,800 Pa keeps it on the glass, with pressure compensation. It detects the pane edge, so frameless glass is fine. It also works on other smooth surfaces.

After a power cut it holds on for 20 minutes. A safety rope is included.
Navigation and control
It plans its path. It comes with a remote. It gives voice prompts. The cable reaches 4 m.
