The GlassVac cleans windows and smooth surfaces in two steps. 1: Mix detergent with water in the applicator and spray it on the surface. Stubborn dirt can be removed at the same time with the integrated microfiber cloth, which can be detached for washing. 2: Switch on the GlassVac, place it on the window and start vacuuming. The products tank, which collects the dirty water, can be emptied easily by opening the rubber plug on the tank and pouring out the water. Includes a free garden bag.
