Introductory comment
OMNIA 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.
