It has been shown that lint from textile material can easily lead to a clogging of a main filter (the second filter). If, for example, a HEPA filter is used as the main filter, cleaning is only possible with great effort.
  • the cleaning operation is effective.
  • the first filter can then also be cleaned with relatively little structural effort.
  • the filter unit is designed as a filter cassette or filter box and can therefore be handled as a whole.

  • the first filter has a min least approximately square or rectangular shape on an upper surface.
  • a cleaning machine with the filter unit can be implemented in a simple manner and the filter unit can be positioned on the cleaning machine in a space-saving manner.
  • the first filter has a height of at most 5 cm. As a result, it can be easily positioned on the housing and connected upstream of the second filter. It is particularly advantageous if the filter can be removed from the housing in order, for example, to be able to knock out or blow out the second filter in an effective manner.
  • the second filter is designed as a main filter; the second filter is arranged in an inner space of the housing; the second filter is designed as a flat pleated filter or a round filter; the second filter comprises a surface filter medium and / or a depth filter medium; the second filter is a particulate filter and / or is a HEPA filter and / or is a ULPA filter and / or is a filter for dust class H or M according to DIN-EN60335-2-69, Annex AA and / or is a Filters of at least particle class H13 according to EN1822-1; the second filter is permanently or detachably connected to the housing.

  • the bottom of the housing is permeable to a suction flow so that it can flow through the second filter.
  • the housing has a receptacle for the first filter, the receptacle being designed as a guide for the first filter and the first filter sitting in the receptacle in the manner of a drawer. The first filter can thus be easily positioned on the housing for a cleaning operation and removed from the housing in order to be able to clean the second filter itself, for example.
  • the first filter forms an independent unit which can be handled as a whole and can be detached from the housing. This results in easy access for an operator.
  • the housing is designed and the second filter is arranged on the housing in such a way that the second filter can be knocked out via the housing.
  • the housing is "hit" against an object in order to loosen dirt particles from the second filter and to be able to remove them from the filter unit.

It is thereby also possible to clean the filter unit (without it being removed from the floor cleaning machine), and in particular to carry out an automatic cleaning. The cleaning only has to be carried out on the first filter, so that a filter such as a HEPA filter can also be used as the second filter, which cannot be cleaned or can only be cleaned with great effort or which can be removed from the floor cleaning machine for cleaning got to.

  • a filter cake 200 on the first filter 146 coherent structures 198 are formed.
  • the squeegee strip 166 acts on the filter cake 200 or on the coherent structures 198, large parts and in particular also accumulated dirt particles in corner regions 202 are carried along.
  • the squeegee strip 166 can remove dirt particles from the first filter 146 in addition to its direct area of influence. It is then not necessary for the wiper strip 166 to protrude into corresponding corner areas 202.
  • the effective length 194 of the squeegee strip 166 is smaller than a corresponding diagonal and, for example, is equal to or smaller than a corresponding width of the first filter 146 parallel to the sides 172a, 172b.
  • the control and / or regulating device 196 automatically carries out the cleaning process in a time-controlled manner. After the aforementioned specific time interval, the fan motor 65b is switched off and the drive motor 160 of the cleaning device 158 is controlled accordingly. The squeegee 166 then performs its oscillating pivoting movement. This oscillating swivel movement is carried out for a certain period of time.
  • the control and / or regulating device 196 then switches the drive motor 160 off again and turns on the fan motor 65b for another cleaning operation, provided that the floor cleaning machine has not been switched off at the main switch in the meantime.
  • the floor cleaning machine according to the invention can be used to effectively clean textile floors.
  • An automatic cleaning can be carried out.
  • the floor cleaning machine shows an effective cleaning effect, it is compact and can be operated by an operator in a simple manner.
  • battery operation of the floor cleaning machine 10 can be implemented in a simple manner.
  • At least one side broom 204 is arranged on the floor cleaning machine 10.
  • the side brush 204 protrudes beyond the front end 16 of the base 12. Furthermore, it protrudes laterally beyond the base 12 in order to enable cleaning close to the edge.
  • the side broom 204 is driven in a rotational movement, with a corresponding axis of rotation being oriented transversely and, for example, perpendicular to the installation plane 42.
