For fast and efficient cleaning of machines, vehicles, laboratories and construction sites: the Kärcher wet-dry vacuum cleaner is a general-purpose machine for professionals in various fields. This compact multi-purpose vacuum cleaner features an automatic Tact cleaning filter and a moisture-resistant flat pleated filter to remove large volumes of contaminants during long working periods. Liquid and solid contaminants can be reliably collected in a durable 30-liter container that has a bumper and solid metal wheels. Easy operation and operation via the new central rotary switch of the machine facilitate the work. The machine is accompanied by newly developed and highly improved components that can be easily stored in the integrated suction hose and has the ability to store components. Rubber surfaces and attachment options mean that tools and boxes can be slidably mounted on the flat head machine or even attached to it.
