With our cordless ash vacuum cleaner AD 2 Battery, the quick removal of ash from wood-burning stoves, pellet heating systems or charcoal grills becomes a dust-free child's play. The powerful 18 V Kärcher Battery Power interchangeable battery with Real Time Technology for displaying the battery life on an integrated LCD display ensures the necessary endurance. In conjunction with well thought-out innovations, such as the ReBoost function for effective filter cleaning at the push of a button, a high and, in particular, constant suction power is guaranteed at all times. Coarse dirt, ash or even fine dust particles are reliably vacuumed - thanks to the beveled hand tube, even in hard-to-reach places. The flexible suction hose made of coated metal and the flame-retardant 14-liter collecting container guarantee the highest level of safety. And thanks to the robust flat pleated filter with an upstream metal coarse dirt filter, the exhaust air also remains dust-free. After the work is done, the suction hose is simply inserted into a recess in the housing of the device and everything is stowed away to save space.
