How to Fix / Troubleshooting

Safety: Remove the battery before cleaning filters or airways.

  • Empty bin and inspect: Empty the dust bin and check for clumps at the inlet and cyclone.
  • Clean pre-motor filter: Remove, tap off dust, and if washable, rinse under lukewarm water. Allow to dry for 24 hours before refitting.
  • Clean post-motor filter: Tap gently to remove dust or replace if heavily soiled.
  • Check wand and tools: Look through the wand and each tool for obstructions. Remove any debris.
  • Test suction at main unit: Run the vacuum with no wand or tools. If suction is strong at the main inlet but weak at the floorhead, the blockage is in the wand or head.
