Machine leaves streaks or fails to lift dirt effectively from carpet

Safety first: Unplug the machine before inspecting the brush head.

• Check bristle length: Inspect the brush roller. If bristles are worn down or uneven, they will not agitate the carpet properly. Replace the SEBO brush roller if bristles are below the wear indicator or noticeably short.
• Adjust height: Set the brush height according to carpet type. For low-pile carpets, use a lower setting; for thick carpets, raise the head slightly to avoid bogging down.
• Clean housing: Remove the bottom plate and clear any lint or debris that may be blocking the brush from contacting the carpet evenly.
• Check brush speed: If the brush seems to slow significantly under normal use, the motor or belt may be weak and require replacement.

Regularly replacing worn brush rollers maintains cleaning performance and protects carpet fibers.
