Brush Cleaning And Maintenance
After each session of carpet cleaning, the brushes and
the brush housing should be cleaned. Before cleaning
or changing the brushes, always unplug the machine
from the power supply.
Brushes are removed without tools. After handle is in
locked position, tilt the machine back and rest on
handle. To release brush from spring clip pull spring clip
away from brush end cap. Lift brush out of machine.
The brushes may be soaked in warm or hot water using
mild detergent, and then rinsed with warm water.
Brushes with crushed bristles can often be restored to
original condition by soaking in hot water.
Keep brushes clean and free from debris. Rotate
brushes after every use as this will increase the life
span of the brushes and ensure even wear.
Before reinstalling brushes, clean out machine brush
housing and hopper by wiping with a clean damp cloth.
