We have some pretty large windows in the new house and it costs a few hundred dollars to get window cleaners in (I can't be bothered doing it myself and don't have the equipment needed to reach some of the higher windows).

I am looking into a window cleaning robot and was wondering if anyone has had any real-life experiences?

There appears to be quite a few similar ones on AliExpress for pretty reasonable money. Just looking for any feedback if anyone here has tried one like this, or others.

Cheers,

Ben
