Symptoms
- Fine scratch marks appear after vacuuming hard floors
- Scratches worse in the vacuum's turning path
- Debris visible stuck to wheels or brush roll edges
- Scratching noise heard while vacuuming
Likely causes
- CommonDebris embedded in wheelsA small stone or hard debris caught in a wheel can drag and scratch the floor as it rolls.
- CommonBrush roll set too low for hard floorsBristles or hard plastic edges of the brush roll can scratch delicate finishes if set for carpet height.
- PossibleHard plastic edges of the nozzle contacting the floorSome nozzle designs have exposed plastic edges that can mar soft or finished wood.
- Less commonWorn wheel material exposing a harder coreRubber coating on wheels can wear away over time, exposing a harder, more abrasive surface underneath.
What to do
- Turn off and unplug the vacuum, then inspect the wheels closely for embedded debris.
- Remove any stones, glass shards, or hard debris stuck in the wheel treads.
- Check the brush roll height setting and switch to the hard floor or lowest aggressive setting if available.
- Look at the nozzle's edges for any exposed hard plastic that contacts the floor directly.
- Test on an inconspicuous area of the floor after cleaning the wheels to see if scratching stops.
- Consider a dedicated hard floor attachment if your vacuum has one, since it's designed without an aggressive brush roll.
- If wheels show worn-through rubber, they likely need replacement to prevent further scratching.
