3.4.3 Useful cleaning tips

Sweep the floor before carrying out wet cleaning. This not only enhances the cleaning effect but also reduces wear of the machine's working tools. If the floors are really dirty or wax needs to be removed, treat the floor twice. In the first step, scrub the floor with a detergent suitable for the degree of soiling; the squeegee remains raised for this. Leave the detergent for approx. 5 to 10 minutes; subsequently scrub the floor again and work with a lowered squeegee.

Note

• Only use detergents suitable for automatic machines (foam retarded). We recommend use of our detergents and care agents specifically developed for the machine. These products meet the requirements of the German Detergent and Cleaning Agent Act (WRMG).

• Observe correct dosing of the detergent. Correct dosing saves money and protects the environment. Strong foam formation is a sign of excessive dosing and impairs machine operation.
