Robot vacuum leaves streaks of fine dust or a trail behind it, especially on hard floors.

Safety first: Turn off the robot before removing the bin.

Steps to resolve:

• Verify filter installation: Remove and reinstall the filter, ensuring it is fully seated and oriented correctly.
• Inspect filter gasket: Check the rubber or foam seal around the filter for tears or deformation; replace the filter if damaged.
• Check bin for cracks: Examine the dust bin for cracks or warping that could allow dust to escape.
• Clean bin interior: Wipe the inside of the bin with a slightly damp cloth and let it dry completely before reinstalling.

When to replace parts: If dust trails persist, replace the filter and, if necessary, the dust bin assembly.
