Our take
HOBOT S7 Pro
Useful for maintaining large or hard-to-reach panes, but not a replacement for manual cleaning. Reviewers consistently like the secure grip and routine cleaning while criticising the noise, slow pace and need for supervision.
It works well on lightly soiled glass, feels secure on the window and can save effort on large panes that are awkward to reach.
It is loud, slow, needs repositioning between panes and struggles with stubborn grime and perfect edge cleaning.
Large framed or frameless panes needing active scrubbing.

What reviewers found
TechRadar found the S7 Pro especially effective on lightly dirty indoor glass, while weathered outside panes still showed streaks. Its strongest case is reducing effort on large windows.
Maintenance versus heavy dirt
In TechRadar’s test, indoor glass partitions finished clear and navigation covered the pane well. Outdoor patio doors improved substantially but retained streaks and occasional track marks. A dry pass before wet cleaning improved results; this remains maintenance cleaning rather than assured removal of stubborn deposits.
[1]Window fit and handling
The reviewer’s 32 cm-wide pane was too narrow for the robot to clean. Frameless partition edges were detected successfully, but the unit detached once during testing, making the tether part of the actual routine. It needs mains power; its backup battery is for temporary adhesion during an outage.
[1]Controls and the remaining work
A tested 1.3 m² pane took roughly seven and a half minutes, followed by moving the robot. The reviewer disliked the remote’s aiming requirement and loud prompts. An update confirms app support through HOBOT LEGEE, correcting the original review’s claim that an app was unavailable; the reviewer had not yet tested that app.
[1]One extensive test supports these observations; its original app-support criticism was subsequently corrected.
