- the turbine T and the first motor Ml are housed in a chamber k and the collector here consists of a flexible bag S with a breathable wall, enclosed in a compartment K delimited upwards and laterally by a rigid waterproof wall and downwards by the membrane M which ensures the separation with the suction chamber k.
- the membrane M can be part of the bag S.
- the turbine T sucks in the compartment K and evacuates the air sucked in a volute 11 which opens into a chamber 12 communicating with the outside through orifices.
- a beater broom in the form of a rotary brush driven by a second motor M2.
- the reference E designates a rechargeable battery which accommodates in a casing A placed under the turbine T and which serves to supply direct current to the two motors Ml and M2.
- the bag S is wedged inside the compartment K by means of projections D integral with the internal wall of the said compartment K and has an opening 20 which fits onto an outlet 21 of a device 30 making it possible to selectively put the communication l inside the bag S, either with a conduit C connected to the beater broom, or with a connector 40 to which one end of a flexible conduit 41 can be fixed, which is equipped at its other end with a suction device 42.
- the reference N denotes a means of gripping the vacuum cleaner in the shape of an inverted U and which can be mounted sliding on the frame.
- FIG. 2 shows the electrical supply circuits of the two motors M1 and M2 according to the state of the art.
- a first general switch SI allows the electrical supply of the first motor Ml for driving the turbine T, in the mixer operating mode and in the suction operating mode.
- a second switch S2 allows, in the closed position, the electrical supply of the second motor M2 of the beater blade B if the first switch SI is also in the closed position.
- Figure 3 shows the electrical wiring of the vacuum cleaner 1 according to the first aspect of the invention which will now be described in detail.
- the two motors Ml and M2 are arranged in series and the first switch SI allows the supply of the two motors Ml and M2 in the closed position.

- the first switch SI When using the vacuum cleaner in beater mode, the first switch SI is in the closed position and the second switch S2 is in the open position. The sum of the voltages applied to the motors Ml and M2 is then equal to the voltage of the battery E.
- the first switch SI When using the vacuum cleaner in suction mode, the first switch SI is in the closed position and the second switch S2 is also in the closed position. The second motor M2 is then shunted or short-circuited. The voltage applied to the first motor Ml is equal to the voltage of the battery E.
- the first switch SI When the vacuum cleaner is at rest, the first switch SI is in the open position.
- the control member of the two switches SI and S2 ensures that in the rest or stop position, the second switch S2 is also in the open position.
- Tables 1 and 2 below show as an example the voltages U (Volt) applied to the motors Ml and M2, the intensity of the current I (Ampere), the power P (Watts), the depression DP (mm of water); and the speed of the turbine N (in number of revolutions / minute), depending on whether the bag S is clean (table 1) or dirty (table 2), in the beater operating mode.
- Table 3 below shows the same values in the case of operation in suction mode, in which the first motor Ml alone is supplied with electric current, depending on whether the bag S is clean or dirty.
- FIGS. 4 and 5 show the device 30 which allows the interior of the bag C to be selectively placed in communication either with the conduit C or with the connector 40 of the flexible conduit 41.
- This device 30 is in the form of a button 31 rotatably mounted around an axis of rotation 32 coaxial with the outlet 21 on which is mounted the opening 20 of the bag S.

In the cylindrical cavity 34 open in opposite directions, perpendicular to the axis X, on the one hand, the connector 35 of the conduit C and the connector 40 of the flexible conduit 41 of the suction device 42.
- the cylindrical body 33 has a bent channel 36, one end of which opens opposite the outlet 21 and the other end of which opens onto the periphery of the cylindrical body 33 and can be placed opposite one of the connections 35 or 40 by rotation of the button 31 around the axis 32.
- the button 31 also has on its external face a gripping means 37, in the form of an ear intended to allow, by manual gripping, the rotation of said button 31 around the axis 32.
- the cylindrical body 33 has near the inner end bearing against the bottom of the cavity 34, a zone 38 which has a diameter smaller than that of the other part of the body 33, and which has at its periphery two cam paths 39a and 39b arranged in parallel planes perpendicular to the axis 32, intended, the first 39a, to control the first switch SI and, the second 39b, to control the second switch S2, these switches SI and S2 being mounted in housings provided at the periphery of the cylindrical cavity 34 and substantially diametrically opposite.
- the first cam path 39a is formed by the cylindrical periphery of the zone 38 and by two diametrically opposite protrusions 44 and 45, while the second cam path 39b is formed by the cylindrical periphery of the zone 38 and by a single protrusion 46 disposed in the immediate vicinity of the protuberance 45.
- the protuberances 44, 45 and 46 are located in the plane of symmetry of the button 31 which contains the center line of the bent channel 36.
- the switch SI In the position of the button 31 shown in FIGS. 4 and 5, the switch SI is closed, the switch S2 is closed and the flexible conduit 41 is in communication with the interior of the bag S via, the connector 40, the channel bent 36 and the outlet 21.
- the first motor Ml is supplied with current
- the second motor M2 is bypassed
- the vacuum cleaner operates in suction mode.
- the switch SI If the button 31 is rotated 180 °, in either direction, about the axis 32, the switch SI is closed, the switch S2 is open, and the conduit C is in communication with the interior of the bag S via the connector 35, the bent channel 36 and the outlet 21.
- the two motors Ml and M2 are thus connected in series and supplied by the battery E.
- the vacuum cleaner then operates in beater mode.
- the button 31 can be easily removed from its housing, which safely causes the switches SI and S2 to open and the motors Ml and M2 to stop. This arrangement makes it easy to clean the bent channel 36 in the event of a jam.
- the device 30, which allows the interior of the bag C to be selectively placed in communication either with the conduit C or with the connector 40 of the flexible conduit 41, is identical to that shown in Figures 4 and 5 and described above.
- the switch SI in the closed position then causes the electrical supply of an electronic power circuit which includes a microprocessor managing the electrical powers delivered to the motors Ml and M2, depending on the opening and closing of the switch S2.
