    The WV 3 Comfort from Kärcher, the inventor of the Window Vac, brings a streak-free shine to all smooth surfaces and is the ideal solution for particularly convenient cleaning. With the practical Hook!It shower hook, the device can be stored in a space-saving manner and is always within easy reach. The XXL dirty water tank enables longer and more efficient cleaning without constant interruptions. The user-friendly and ergonomic design ensures comfortable handling. In combination with a spray bottle with a microfiber wiping cloth, cleaning with the WV 3 Comfort is up to three times faster than with conventional methods. You get streak-free cleaning results without dripping dirty water. Thanks to 360° Comfort!Clean, the Window Vac can be used in a variety of ways, even at an angle, horizontally, or overhead. The battery run time of 35 minutes enables users to clean areas of up to 1,100 square feet. USB-C charging makes recharging easy.
