They then hit the separation device. there the drops partially pass through the separating device. Any solid particles that are carried along are not thereby complete separated and emerge again at the air outlet. If the device is out of operation again, cleaning liquid can enter the the motor above evaporate.

For this it is necessary to first fill the opening unscrew the lid closing the container, then unscrew the fastening cap from the motor shaft and then to remove the separator from the motor shaft. Only then can remove the container from the base after loosening it. Designed through this changing the fluid becomes cumbersome and difficult.
  • the invention has for its object the generic wet cleaning device to be trained so that handling when changing the liquid is relieved.
  • the rotatably driven Separator connected to the liquid container so that he removed it together with him to change the fluid becomes.
  • the separator therefore does not have to be separate from the liquid container or be removed from the blower motor. Accordingly the liquid container can be easily combined with the Attach the separator to the wet cleaning device again. Designed through this changing the liquid is very easy and problem-free. This is helped by the fact that the liquid container is formed in two parts is. So the container top can be removed, so that the liquid is simply emptied from the lower part of the container and into it can be filled.
  • the liquid container is above, next to or around the engine arranged. This easily avoids that the cleaning liquid can evaporate into the engine when the device is turned off. This will cause mold to form on the device parts safely avoided.

Also a comparatively small device size and one significant weight reduction can be achieved. It is also advantageous that the center of gravity of the device is shifted as far down as possible can be achieved and thus the greatest possible stability becomes.
