The Kärcher WV 6 Plus D500 is a cordless window cleaning system designed for efficient, streak-free cleaning of smooth surfaces. This successor model of the WV 6 Plus features improved silicone suction bar technology and an extended battery life of 100 minutes, allowing for the cleaning of approximately 300 square meters per charge. The system includes 500 ml of window cleaning concentrate and a spray bottle with a microfiber cloth cover for comprehensive cleaning. With a working width of 280 mm and a dirty water tank capacity of 150 ml, this window vacuum operates with lithium-ion battery technology and takes about 170 minutes for a full charge. The ergonomic design includes a precise display with a remaining runtime indicator in minutes for better cleaning planning. Weighing 0.8 kg and measuring 126 mm × 280 mm × 310 mm, this white plastic construction ensures hygienic operation by avoiding direct contact with dirty water during tank emptying. The quiet operation enhances user comfort, while the electronic water suction system guarantees streak-free results on various smooth surfaces such as windows, mirrors, tiles, glass tables, and shower cabins. This model represents the original quality from the inventor of window vacuum technology and offers approximately three times faster cleaning compared to traditional methods, with reliable performance and durable construction for regular household use.
