The terms "electric window vacuum" and "electric window cleaner" are usually used interchangeably for various devices that are designed to make window cleaning easier and more effective. In addition to window vacuums, there are also window cleaning robots and battery-powered window wipers.
Intelligent window cleaning robots work independently, at least in theory. They clean windows by themselves but do need to be constantly monitored when they’re operating. They are also relatively complicated to install. While many battery-powered window wipers are a good replacement for a spray bottle and a cloth, they do not have a suction function.
