Its rotatable roller brush head with KART technology (Kärcher Advanced Response Technology) allows work on tight bends, thus ensuring maximum manoeuvrability and agility. The powerful, long-lasting lithium-ion battery makes possible long applications, can also be recharged quickly, is completely maintenance-free and lasts up to 3 times longer than typical lead batteries. The excellent equipment of the BR 35/12 C is complemented by the connectible eco!efficiency mode, which lowers the energy consumption considerably at the touch of a button, extends the runtime of the battery and also reduces the operating noise by around 40 percent, thus permitting applications in noise-sensitive areas.
