A Pleated Filter in your multi surface cleaner acts as a protection to the dirty water tank!
The unique pleated filter enables non-stop vacuuming of wet and dry dirt – without any filter exchange or interruption of work. As the filter doesn't get wet, the otherwise necessary working steps are eliminated: remove the filter, let it dry, re-install. This saves time and allows a high level of flexibility during its application.
If the airflow from your cleaner is blocked for extended periods of time it can put an additional stress on your motor. Replace a damaged or clogged filter with the quality replacement to ensure optimum performance.
