Fine dust appears to bypass the cyclone and collect directly on the pre-motor filter.

Safety first: Remove the battery pack before disassembling the cyclone.

• 1. Disassemble cyclone: Remove the dust bin and separate the cyclone assembly according to the manual.
• 2. Clean cyclone parts: Use a soft brush to clean the cyclone cone, mesh, and inlet slots. Do not use water unless the manual allows it, and ensure complete drying before reassembly.
• 3. Check for damage: Inspect the cyclone cone for cracks or missing pieces. Replace the cyclone assembly if damaged.
• 4. Observe fill level: Always empty the bin before it reaches the max fill line to maintain cyclone efficiency.
