How to Fix / Troubleshooting
Safety first: Remove the battery before clearing blockages.
- Empty bin: Ensure the dust bin is emptied before it reaches the max fill line.
- Check nozzle and wand: Look for clogs near the nozzle opening and in the lower wand. Clear any obstructions.
- Inspect cyclone assembly: Make sure the cyclone and bin are assembled correctly and seated firmly.
- Check flap valves: Some models have rubber flaps to prevent backflow. Inspect for tears or deformation and replace if damaged.
