Vacuum leaves lines of debris behind and does not pick up well from carpets

Safety first: Remove the battery and detach the floor nozzle.

• Inspect bristles: Examine the brush roll. If bristles are very short, uneven, or matted, they will not agitate carpet effectively.
• Clean brush: Remove all hair and fibers. Wash the brush only if the manual allows, then dry completely.
• Check installation: Ensure the brush roll is seated correctly in both end bearings and that the side cap is locked.
• Nozzle settings: If your Bosch nozzle has a hard floor/carpet selector, set it to carpet so the brush can contact the fibers.
• Replace brush roll: If bristles are visibly worn or the core is damaged, replace the brush roll with a genuine Bosch part.
