Introductory comment
GENIE B is a floor scrubbing machine which, via the
mechanical action of the rotating brush and the chemical
action of a water/detergent solution, can clean any type of
flooring. As it advances, it also collects the dirt removed and
the detergent solution not absorbed by the floor.
The machine must be used only for this purpose. Even
the best machines will only work well if used correctly and
kept in good working order. We therefore suggest you read
this instruction booklet carefully and read it again whenever
difficulties arise while using the machine. If necessary,
remember that our assistance service (organised in
collaboration with our dealers) is always available for advice
or direct intervention.
Intended use
The scrubbing machine is designed exclusively for the
professional cleaning of surfaces and floors in industrial,
commercial and public environments. The machine is only
suitable for use in closed (or at least covered) places.
The machine is not suitable for use in the rain, or under
water jets. It is FORBIDDEN to use the machine in places
with a potentially explosive atmosphere, for picking up
dangerous dusts or inflammable liquids. In addition, it is not
suitable as a means of transport for people or objects.
