36. THE MACHINE DOES NOT CLEAN WELL
1. Check the state of wear and tear of the brush and, if necessary, replace it (the
brush must be replaced when the bristles are about 15 mm long).
2. Use a different kind of brush to the one fitted as standard. For cleaning floors
where the dirt is particularly resistant, we recommend the use of special brushes
supplied upon request and according to needs (see “CHOOSING AND USING
THE BRUSHES”).
37. THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check the squeegee rubbers are clean.
2. Adjust the inclination and height of the squeegee (see the “ADJUSTING THE
SQUEEGEE INCLINATION AND HEIGHT” paragraph).
3. Check the suction tube is correctly inserted in its housing on the recovery tank
and in the suction nozzle in the squeegee. Check it is not clogged too.
4. Check the inner filter of the recovery tank is not dirty and, if necessary, clean it
thoroughly.
38. EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity
of antifoam liquid to the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this
case the detergent solution should be more diluted.
