1. Check the condition of the brush and replace if necessary. Brush must be replaced when bristles are about 15 mm. high.
Refer to "REMOVING THE BRUSH" and "INSTALLING THE BRUSH" to replace it. Working with a brush that is too worn
may cause damage to the floor.
2. Use another type of brush rather than the standard brush. To clean floors with exceptionally tough dirt, we recommend the
use of special brushes that are supplied on request and according to your specific needs.

Too much foam is generated
Check that a low-foam detergent has been used. Add if necessary a small quantity of anti-foam liquid to the recuperation tank.
Remember that more foam is generated when the floor to be cleaned is not very dirty. In this case use a more diluted detergent
solution.
