Description

    FIELD
  • [0001]
    The present disclosure relates to a floor scrubbing machine.
  • BACKGROUND
  • [0002]
    Conventional floor scrubbing machines have a supporting base for at least one rotating brush and for at least one dispenser of a washing liquid.
  • [0003]
    To the rear of the brush, along the forward direction of travel of the machine, there is a squeegee that retains the washing liquid and the dirt removed from the floor so that they are picked up by an intake so as to leave the floor dry and clean.
  • [0004]
    A tank for the washing liquid, which supplies the dispenser, and a tank for collecting the dirty liquid drawn by the intake are mounted on the supporting base.
  • [0005]
    In current machines, the tank for the washing liquid and the tank for collecting the dirty liquid are arranged laterally with respect to a vertical central plane of the machine and therefore the machines have a considerable lateral space occupation, which makes them awkward to use in tight spaces, such as for example in a home environment.
  • [0006]
    Furthermore, these tanks are arranged inside an enclosure and their removal from the supporting base for ordinary operations for maintenance and cleaning of the machine is very awkward to perform.
  • SUMMARY
