The new battery-operated Karcher T 9/1 Bp dry vacuum cleaner effortlessly combines cordless flexibility with the performance and cleaning quality of a mains-operated dry vacuum cleaner. The high-performance lithium-ion battery has a runtime of 24 minutes (46 minutes with eco!efficiency) – enough time for intensive cleaning. The battery can be changed quickly and easily at any time as required so that extended work intervals are possible. The robust and low-noise machine is customised to the needs of hotels and retailers and can also be used when the area is open to the general public. The battery-operated dry vacuum cleaner is also suitable for building service contractors or transport operators – for example, for fast intermediate cleaning of the vehicle. The accessories are included as standard. A battery, a quick charger, as well as a tearproof fleece filter bag, which compared to traditional paper filters can absorb twice the amount of dirt.
