Robot vacuum leaves marks or scratches on delicate floors.

Safety first: Turn the robot OFF and inspect the underside carefully.

• 1. Inspect main brush: Check for stiff, frayed, or broken bristles that could scratch surfaces. Replace the Electrolux main brush if damaged.
• 2. Check front caster: Spin the front caster wheel. If it is rough, chipped, or does not rotate freely, replace the caster assembly.
• 3. Look for protruding screws: Ensure all bottom plate screws are flush with the surface. Tighten any loose screws.
• 4. Smooth sharp edges: If any plastic edges are rough from wear, lightly smooth them with fine sandpaper, taking care not to alter functional surfaces.
• 5. Test on a small area: After repairs, test the robot on a small, inconspicuous area of the floor to confirm no further marking.
