A device for extracting drilling sludge for use at difficult to access locations on a building site includes a main body. The main body has a cavity on a lower side of the main body and a drilling sludge that is disposed in the cavity during a use of the device is extractable from the cavity by a suction device. The main body also has an extraction opening which opens into the cavity.

Device for extracting drilling sludge and the use thereof

An arrangement of components in a portable wet vacuum cleaner, wherein the wet vacuum cleaner includes a container for collecting a liquid-dirt mixture. The component arrangement is characterized, in particular, by a sloping sealing plane as the upper termination of a collecting container of the wet vacuum cleaner, wherein the sloping sealing plane includes a filter unit. In a second aspect, the invention furthermore relates to a wet vacuum cleaner having a component arrangement of this kind.
