Getting started

Maintaining your machine

Useful tips

Don't overfill it

Keep one eye on the bin and empty it as soon as debris reaches the MAX marker to maintain suction.
Reach anywhere

The instant release wand's long hose reaches all over and releases in one smooth action. Just attach the right tool for the job.
Safely store tools

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