Choosing guide
Whether a window-cleaning robot works well depends partly on which side of the glass it needs to clean. Exterior cleaning is the most common use case among the models reviewed on this site, so you get the widest choice and generally strong ratings. Interior cleaning covers a smaller group of models, still well rated but with fewer options to compare. Check a model's rating for the side you actually need before buying, since a strong score on one side does not guarantee the same result on the other.
