The floor tool shown may vary from the product selected but the process remains the same.

Don't overfill it

To maintain suction, keep an eye on the bin and empty it as soon as debris reaches the MAX marker.

Wash the filter regularly

Rinse under a cold tap until the water runs clear – you don't need any detergents. Leave to dry fully (at least 24 hours) before refitting.

Safely store tools

Clip accessories onto the vacuum's tool holster so you've always got them to hand.
