Useful tips

  • Don't overfill it

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

  • Reach up high

    Press the release catch to adjust the extension tube. Listen for the click when it's at the right length.

  • Safely store tools

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