You can clean windows, mirrors, shower cabins and tiles very quickly and easily with the Karcher WV1 Plus. Before you start, fill the spray bottle with water and detergent. With the microfiber cloth you spread the soapy water over the surface and remove the biggest dirt from the mirrors or windows. Then pick up the windscreen wiper, which you pull over the surface from top to bottom. You can soak up the water and dirt in the reservoir. When you're done, simply empty the reservoir and take a satisfied look at the clean windows.
