Washing your Fluffy™ brush bars
Fluffy TM brushbar may not be included in box.
Your machine has two washable brush bars. To maintain optimum
performance, check and wash your brush bars regularly.
Make sure your machine is disconnected from the charger and take
care not to touch the trigger.
Remove your brush bars
Don't put your brush bars in a dishwasher, washing machine, tumble dryer,
oven, microwave or near a naked flame.
Only use cold water to wash your brush bars and don't use any detergents.
Turn the cleaner head upside down. Use a coin to turn the end cap lock 180°
anticlockwise until it clicks into the unlocked position.
Push the end cap up to the open position and slide the brush bar out of the
cleaner head.
Remove the end cap from the brush bar and don't wash it.
Lift the smaller brush bar out of the cleaner head.
Wash and dry your brush bars
Hold your brush bars under running water and gently rub to remove any lint
or dirt.
Stand your brush bars upright as shown. Leave to dry completely for at least
24 hours.
