Description:
The washing function
of the machine
is obtained by the interaction of the
cleaning solution with the dirt present
on the floor.
To facilitate
and enhance this inter-
action, is used a system of mechanical
rubbing which consists in a device
which rubs on the floor.
This device
in this case a cylindrical
brush, has the function to mechanically
remove the dirt from the ground and
facilitate the reaction between the dirt
and cleaning solution.
An electric brushless motor
provides
the rotational movement of the brush
coupling shaft.
To the shaft
is coupled the brush that
rotates together with the shaft itself.
After lowering the base to the ground,
the brush touches and rubs on the
floor providing the desired mechanical
rubbing.
