Possible Causes

Dust bin overfilled, Cyclone separator clogged with fine dust, Blocked wand or hose, Misinstalled or saturated pre‑motor filter

How to Fix / Troubleshooting

Safety first: Turn OFF the vacuum and remove it from the charger before disassembly.

  • Empty the bin: Remove and empty the dust bin. Tap it gently to dislodge compacted debris.
  • Clean cyclone assembly: Detach the cyclone unit from the bin (if separate). Use a soft brush to remove fine dust from the cyclone cones and mesh screens. Do not wash unless the manual explicitly allows it.
  • Check wand and hose: Look through the wand and any flexible hose for blockages. Push out clogs with a blunt, non‑sharp rod.
  • Service filters: Remove the pre‑motor filter and HEPA filter. Tap gently to remove dust; wash only if labeled washable and dry completely before reinstalling.
  • Inspect seals: Ensure all gaskets and seals between the bin, cyclone, and motor housing are intact and seated properly to prevent air leaks.
