traction hub motor. brush head gearmotors and vacuum motor. When the drive pedal is pressed, both the brush head and the squeegee will move to the
working position, and as soon as it is in contact with the ground the brush head gearmotors and the vacuum motor start working in full working order. If the
machine stops and the foot pedal is released during the operation, the brush head body will start to rise to return to the rest position, and after a period of
time the gearmotors will switch o󰀨. The squeegee body will stay in contact with the oor for a few seconds, after which it will raise up from the ground and
return to its rest position. For all these phases the vacuum motor will continue to operate, only after a few seconds that it has returned to its rest position will
it switch o󰀨, this is to allow the motor to collect all the liquid in the vacuum hose. During these phases, the symbol of the vacuum motor on the instrument
panel display will blink, and it will only stop when the squeegee is in its rest position and the vacuum motor is o󰀨. If reverse is carried out with this program
active, the squeegee will move to the rest position, the vacuum motor will keep working for a pre-set time and then it will switch o󰀨.
Scrubbing without drying function:
With the selector in scrubbing without drying mode, it is possible to scrub the oor without vacuuming the detergent solution applied. The main actuators
active are those of the traction hub motor and the brush head gearmotors. When the drive pedal is pressed, the brush head will move to the working position,
and as soon as it is in contact with the ground the brush head gearmotors start working in full working order. If the machine stops and the foot pedal is
