Washing the filter
Removing the filter
Remove the filter unit by twisting it counterclockwise. Gently pull away from the machine.
Gently tap the filter unit to remove any excess dust and debris before washing it.
Wash the filter unit in cold water only: do not use detergent, or wash it in a dishwasher or washing machine.
Wash the pleated paper element of the filter unit first; hold the filter unit under a cold water tap with the foam element downwards and run cold water over the pleated paper. Continue washing until the water runs clear.
Wash the foam element of the filter unit next; hold the filter unit under a cold water tap with the foam element downwards so that dirty water does not contaminate the pleated paper element. Run cold water over the inside and outside of the foam element and squeeze the foam gently to expel the dirt. Continue washing until the water runs clear.
Wash the outside of the filter unit. Then fill the unit with cold water, place your hands over the open ends and shake gently. Repeat washing the elements and outside of the filter unit until the water runs clear.
Gently shake the filter unit to remove any excess water and leave to drain with the foam element end facing up.
Drying
Leave the filter unit to dry completely in a dry environment with good airflow, for a minimum of 24 hours. Check that the filter unit is completely dry.
Refit
To refit, return the filter unit to the main body and twist clockwise until it clicks into place.
The filter unit may require more frequent washing if vacuuming fine dust or if use is mainly in Boost mode.
