Clean the bin and cyclone

A damp or musty smell is caused when dust in the cyclone has come into contact with water.

It may not be a direct contact with water, for example when vacuuming pet hair that is slightly damp, this moisture will combine with the dust in the cyclone causing the smell.

Additionally the smell may occur if the filter goes back into the machine wet.

Remove the bin by pressing the catch on top of the carry handle.

Push the button to release dust directly into a dustbin or bag.

Release the bin from the cyclone by pressing the button on the back of the cyclone.

Clean the cyclone with a dry cloth and shake or tap firmly to remove all dust from inside the fine dust collector.

WARNING: Do not get any part of the cyclone damp or wet.

You can use cold water to clean the clear bin.

WARNING: Do not use detergents or other chemicals.

Ensure the bin is completely dry before attaching back to the cyclone, and press firmly on the centre of the clear bin base to close before placing back on the machine.
