- the suction chamber can be sealed well and a high suction force is provided. As a result, can effectively suck cracks and the like on the surface to be cleaned.
- the first position or the second position can be adjusted via the movement mechanism. This allows an operator set by a corresponding stroke, if he wants to have an increased suction, in particular for a scoring, or if he wants to release the openings in a normal suction, to allow a high dirt pickup of dirt particles on the surface to be cleaned.
- the movement mechanism is designed such that it couples the position of the at least one movable strip to a stroke direction of the floor nozzle on the surface to be cleaned.
- a coupling to a forward stroke direction and to a reverse stroke direction is provided. If the openings are released for a forward stroke, then a "normal" dirt pickup is possible. For example, if the openings are covered for a reverse stroke, then effectively scratches and the like can be sucked out.
- the corresponding function is set automatically.
- the abutment means comprises a first longitudinal side, a second longitudinal side spaced from the first longitudinal side, a first transverse side disposed between the first longitudinal side and the second longitudinal side, and a second transverse side spaced from the first transverse side and between the first longitudinal side and the second longitudinal side is arranged, wherein the openings are arranged on the first longitudinal side and / or the second longitudinal side and wherein the at least one movable strip is associated with the first longitudinal side and / or the second longitudinal side.

- the means movable to the bottom body comprises a roller device, and in particular that the second arm is coupled to the movable device in the region of the roller device.
- the roller device can be used to "detect" which stroke direction is present in a simple manner, and this detection result can then be easily determined by the coupling of the second arm, which is preferably coupled to the movable device in the region of the roller device, to the first Arm and thus transferred to the at least one movable bar.
- first arm and the second arm are hinged to each other via a guide device, which allows a relative displacement between the first arm and the second arm, wherein the guide device comprises in particular a recess pin guide (link guide).

- the resulting positions 108 (in broken lines) and 114 of the movable bar 104 are shown, wherein the first position 108 of the movable bar 104 corresponds to the first position 162 of the device 160, and the second position 114 of the movable bar 104 with the second position 164 of the device 160 corresponds. This results in extended application possibilities.
- the floor nozzle can be basically the same design as the floor nozzle, which is described in the non-prepublished international application PCT / EP2015 / 054764 dated 6 March 2015 by the same applicant, the floor nozzle 10 then the additional functionality of the movable bar 104 in comparison to having the floor nozzle described in PCT / EP2015 / 054764.
- the floor nozzle 10 In a cleaning operation of a vacuum cleaner, which is provided with the floor nozzle 10, the floor nozzle 10 is placed on the surface to be cleaned 72. In a hard surface cleaning function, the contact device 74 is brought into its operative position, so that it touches the face 72 to be cleaned with its end face 76. Depending on whether the floor nozzle 10 is moved on the surface to be cleaned in the forward stroke direction 64 ("pushed") or in the reverse stroke direction 66 ("pulled"), the movable bar 104 is in the second position 114 (release position) or in the first position 108 (cover position).
- An operator can thereby adjust over the stroke direction of the floor nozzle 10 on the surface to be cleaned 72, in which position (108 or 114), the movable bar 104 is located.
- the lifting device automatically adjusts the position of the strip 104.
- the automatic adjustment is made in accordance with the "natural application", so that an operator can use the
- Position adjustment does not have to think, but the correct position, as mentioned, automatically adjusts itself.
- the movement mechanism 116 has been described in the context of the first arm 118 and the second arm 128. It can be provided that a plurality of elements are provided corresponding to the first arm 118, which are spaced from each other. It is also possible that a plurality of elements corresponding to the second arm 128 are provided spaced from each other.
- the at least one movable bar 104 is then held by these first arms 118. Accordingly, the second arm or arms 128 then couple to the first arms 118.
- a locking device 170 is provided (see FIG. 2), which serves to fix the first position 108 and / or the second position 114, so that the moving bar does not move even if the lifting direction is changed. As a result, it is possible in particular under the control of an operator to determine in which position the strip 104 is held.
- the detection Device 170 is formed so that the second position 114 can be fixed. As a result, the bar 104 is set "in a non-operative position".
- the first position 108 is determined. Thereby, the movable bar 104 is constantly in an operative position, regardless of whether a forward stroke or backward stroke of the floor nozzle 10 takes place.
- an operator may set both the first position 108 and the second position 114 as alternatives.
- the locking device 170 By the locking device 170, the automatic adjustment of the position of the movable bar 104 in its first position 108 or in its second position 114, depending on the stroke direction of the floor nozzle 10, so to speak, "off".
- the movement mechanism 116 is blocked.
- the locking device 170 includes a switch 172, which is accessible to an operator.
- This switch 172 is arranged, for example, on the upper side 24 of the housing 12 or on a lateral side, such as the first side wall 18.
- the switch 172 is coupled to an element 174, which acts on the movement mechanism 116 and can effect a corresponding blocking of the mobility of the quiet 104.
- the element 174 is a pin member which is supported in the housing 12 so that it can act on the recess 134 of the recess pin guide 132.
- the pin element 174 is arranged and dimensioned such that it blocks the first position 108 (FIG. 5).
- the pin member 174 may also be immersed in the recess 134, wherein the immersibility is controlled via the switch 172.
- a pivotal movement of the first arm 118 is blocked by the pin member 174 blocking relative movement of the pin 136 to the recess 134.
- a direction of insertion 176 for the pin element 174 is indicated.
- the element 174 is correspondingly slidably mounted in the immersion direction 176, in order to allow immersion into the recess 134 or a replaceability.
- the storage of the element 174 is, depending on the embodiment, such that the second position 114 can be fixed or the first position 108 can be fixed. It is also possible to provide a plurality and in particular two corresponding elements 174, wherein an element serves to fix the second position 114 and an element to fix the first position 108. It may alternatively be provided a single element corresponding to the element 174, which also has a mobility transverse to the immersion direction 176, depending on the position of the switch 172, which is then in particular a rotary switch, a determination of the first position 108 or the second Position 114. (In another switch position, the element 174 is then positioned so that it does not act on the recess pin guide 132.)
