Brush bar spins intermittently or slows down significantly on carpet

Safety first: Unplug the machine before servicing the brush bar.

• Remove and clean brush bar: Take out the brush bar and thoroughly remove hair and fibres from the bristles and end caps.
• Lubricate or replace bearings: If the end caps contain bearings, check for smooth rotation. Lightly lubricate with a suitable light machine oil if serviceable, or replace the brush bar if bearings are sealed and rough.
• Replace belt: Even if not broken, a stretched belt can slip under load. Fit a new genuine Vax belt.
• Check carpet height: On models with height adjustment, raise the brush height slightly on very thick carpets to reduce load.
