Our take
HOBOT 298
It cleans glass reasonably well and is useful for inaccessible windows, but it is extremely loud and still leaves some finishing work for you.
Owners report generally satisfactory glass cleaning and reliable movement across large panes.
Noise is the standout complaint — owners compare it with a full-size vacuum cleaner — and the final result is good rather than perfect.
Glass-cleaning jobs that benefit from ultrasonic spray nozzle.

What owners and reviewers say
A verified 298 purchaser found it helpful for approximate everyday cleanliness, but their follow-up reported repeated tank leaks and a later hardware fault.
Useful, with a finish compromise
The purchaser’s initial assessment distinguished keeping windows reasonably clean with less effort from achieving the finish they could obtain manually. That is a more measured account than assuming the robot either replaces hand cleaning completely or provides no benefit.
[1]A documented repair experience
Their tank began leaking after a few uses. A replacement arrived fairly quickly, but the follow-up described another leak, small cracks near the fasteners and a hardware error that prevented starting. They ultimately withdrew their recommendation. This is evidence of one buyer’s repeated trouble, not proof that every 298 develops the same fault.
[1]What to weigh in the evidence
The report is useful because it follows the purchase through replacement rather than stopping at unboxing. It remains an older individual case, however, and does not establish whether later production changed the tank or whether present-day service arrangements are comparable.
[1]The previously linked noise discussion was inaccessible. This summary uses a separately checked purchaser report instead.
