The world's first lithium-ion cordless window and flat surface wet vacuum, the Karcher WV50 Power Squeegee helps reduce the time, labor and mess associated with traditional cleaning methods. Simply spray the cleaning solution of choice, turn the vacuum on and run the blades along the surface - it's that easy. Easy to use and cost effective, the WV50 Power Squeegee eliminates the wiping, rubbing and mess required when using paper or cloth towels and you'll save money by not having to wash cloths or throw away paper towels. Plus, the WV50 Power Squeegee is ideal for those who suffer from arthritis, carpel tunnel or other joint and muscle aliments that make rubbing or wiping a painful process. Ideal for most non-porous surfaces, the WV50 Power Squeegee can clean windows, mirrors, sky-lights, tiles, smooth granite and stone surfaces - without leaving any streaks. It features double-layered 11 in. blades made of long-lasting neoprene and edge-to-edge suction on any flat surface. The WV50 Power Squeegee is powered by an advanced lithium-ion battery that offers a higher energy output and runs up to three times longer between charges. Thanks to its cordless design, you can use the WV50 Power Squeegee anywhere. It comes with a 12-volt wall charger that automatically maintains a peak battery charge level and the WV50 Power Squeegee has an LED indicator that shows when the device is fully charged.
