Robot vacuum leaves lines of dirt and hair on the floor, especially behind it.

Safety: Turn OFF the robot.

Steps:

• Check main brush condition: Remove the brush and inspect bristles. If they are very short, bent, or missing, replace the Bagotte main brush.
• Inspect brush guard: Ensure the brush guard clicks firmly into place and is not warped.
• Verify dust bin seating: Remove and reinsert the bin until it locks fully. A loose bin can cause poor suction at the brush.
• Check seals/gaskets: Look for foam or rubber seals around the brush opening and bin interface. If torn or missing, replace the brush guard assembly or dust bin.
