If you're encountering a blockage or loss in performance with your Dyson V12 Detect Slim™, it could be because you need to clean your filter. To do so:

• Remove the filter by turning it anticlockwise. Gently pull it away from the machine.
• Gently tap the filter unit to remove any excess dust and debris before washing it.
• Wash the filter in warm running tap water. WARNING: Please do not use detergent, do not wash in a dishwasher or washing machine.
• Wash the pleated paper element of the filter unit under warm running tap water with the foam element downwards and run warm water over the pleated paper. Continue washing until the water runs clear.
• Wash the foam element of the filter unit under warm running water tap with the foam element downwards so that dirty water does not contaminate the pleated paper element. 
• Run warm 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 warm 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.
• Leave the filter to dry for a minimum of 24 hours in an environment with good airflow. Ensure that the filter is completely dry before reinserting it into the machine.
• Insert the filter back into the machine. Turn the filter clockwise until it clicks into place.
• The filter may need to be washed more frequently if you are vacuuming a lot of fine dust, or if the machine is predominantly being used in Boost mode.
