Thanks to its battery operation, the WD 1 Compact Battery multi-purpose vacuum cleaner offers maximum freedom of movement, can be used without a power connection, and is also extremely compact and lightweight. Depending on the 18 V Battery Power battery (not included), the vacuum cleaner operates for 10 to 20 minutes. Additionally, the WD 1 Compact Battery features a robust 7-liter plastic container and a cartridge filter for conveniently vacuuming both dry and wet dirt without the need for filter changes. Other features include an optimized suction hose and special accessories such as a crevice nozzle and upholstery nozzle, which significantly contribute to optimal dirt pickup and ensure thorough cleanliness, especially during car interior cleaning. The flexible rubber band for securely fixing the suction hose is also practical. Additional extras like the blowing function, the "Pull & Push" closure system, the ergonomic carrying handle, and accessory storage make working with the WD 1 Compact Battery a pure pleasure. Furthermore, thanks to compatibility with the 18 V battery platform, batteries from other 18 V Battery Power devices can also be used in the WD 1 Compact Battery.
