  • deactivation of the rotating brush 39 can take place in case of need, during cleaning of particularly delicate surfaces, for example.
  • the machine 1 may comprise an electric motor connected to the brush.
  • the portion of the base 2 integrating the main and auxiliary suction openings, 4 and 33, rotating brush 30, turbine 39, door 56 and closing device 34 can be made as one unit separated from the portion of the base 2 housing the boiler 15, if any, the suction means 9 and remaining components of the machine 1, to define a multifunctional device 100 in the form of a separate accessory provided with a connecting end piece 58.
  • the connecting end piece 58 can be connected by means if rigid pipes and/or flexible hoses to the suction means 9 and/or the possible boiler 15, possibly integrated into a holding structure made in the form of a carriage.
  • the closing device comprises a shutter 57 that is slidable or hinged with respect to base 2 close to the mouths 36, 37 terminating at the main 4 and auxiliary 33 suction openings, respectively.
  • shutter 57 is movable between a first position at which as shown in Fig. 10a, it closes mouth 37 of the auxiliary suction opening 33, and a second position at which it closes mouth 36 of the main suction opening 4, as shown in Fig. 10b.
