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 pleated filter with a pre-filter made of metal ensure maximum safety and dust-free vacuuming. The innovative ReBoost function provides consistently high suction power by cleaning the filter of ash and dust at the push of a button. The necessary power and endurance are supplied by the powerful 18 V Kärcher Battery Power exchangeable battery with Real Time Technology, which displays the battery life on an integrated LCD screen. Hard-to-reach areas are easily accessible thanks to the angled hand tube. A clever recess for inserting the suction hose in the housing of the compact device facilitates space-saving storage after work is done. Please note that this model does not include the battery and requires an additional battery charger.
