Fine dust accumulates around the connection between dust bin and main body, with visible leaks during use.

Safety first: Remove the battery and detach the dust bin.

• Clean seal and mating surfaces: Wipe the rubber seal and plastic mating surfaces with a dry or slightly damp cloth. Remove any grit or hair.
• Inspect seal condition: Look for tears, flat spots, or hardened rubber. Replace the seal or bin if damaged.
• Refit carefully: Reattach the bin, ensuring it is aligned and fully latched without gaps.

Persistent leakage after seal cleaning usually indicates the need for a new dust bin or seal kit specific to your Zanussi cordless vacuum model.
