Why does the VB100 have a motor protection filter and does it have to be cleaned or replaced?

The motor protection filter protects the battery-powered vacuum cleaner from contamination.

The regular visual inspection and maintenance of the motor protection filter is particularly important for the long service life of your battery-powered vacuum cleaner. The motor protection filter can be cleaned again and again. However, it must not be cleaned with water or liquid cleaners!

You only have to replace the motor protection filter if it is extremely dirty or sticky, or if the filter bag has been damaged.
