The Karcher WV 1 is a battery-powered window vacuum designed to make cleaning smooth surfaces like windows, mirrors, and tiles much simpler. This handheld device uses a lithium-ion battery that provides up to 25 minutes of runtime on a single charge, which is enough to cover areas up to 70 square metres. It works by suctioning away moisture and dirty water, leaving surfaces dry and streak-free without the need for traditional cloths. Weighing only 0.5 kg, the vacuum is lightweight and ergonomic, making it easy to handle during extended cleaning sessions. It features a 100 ml water tank and a container-style dust collector that can be emptied hygienically. The device is compatible with standard window cleaning agents, provided they do not contain spirits or foam. The package includes the vacuum and its charger, offering a practical solution for anyone looking to remove condensation or grime from glass and ceramic surfaces quickly.
