The powerful battery-powered ash vacuum AD 2 Battery is specifically designed to reliably and safely remove coarse dirt as well as fine dust particles. A flexible suction hose made of coated metal, a flame-retardant collection container with a volume of 14 liters, and a robust flat-fold filter with a pre-filter for coarse dirt made of metal ensure maximum safety and dust-free vacuuming. The innovative ReBoost function provides consistently high suction power by cleaning the filter at the push of a button from ash and dust. The powerful 18 V Kärcher Battery Power exchangeable battery with Real Time Technology displays the battery runtime on an integrated LCD screen, providing the necessary power and endurance. Hard-to-reach areas are easily accessible thanks to the angled hand pipe. A clever recess for inserting the suction hose in the housing of the compact device facilitates space-saving storage after use. Please note that this model does not include the battery, and an additional battery charger is required.
