摘要： In a vacuum cleaner nozzle (N) comprising one or more rear wheels (RW), a hinge (H3) is arranged to lift all one or more rear wheels (RW) from a floor (F) when a suction tube (ST) connected to the nozzle (N) is rotated around a longitudinal axis of the suction tube (ST), e.g. after the nozzle (N) has been rotated by more than 45° by means of a further hinge (H2) in order to position a relatively short side of the nozzle at the front of the nozzle in the nozzle's motion direction so that the nozzle is able to clean relatively small spaces that could not be entered if a relatively long side of the nozzle is at the front of the nozzle in the nozzle's motion direction. If the one or more rear wheels (RW) comprise at least two rear wheels, the hinge (H3) is arranged for simultaneously lifting the rear wheels (RW) from the floor (F). Preferably, the hinge (H3) is bi-stable, to which end the hinge (H3) may be provided with magnets (M1-2, M3-4) or a bi-stable spring (S) to fix the hinge (H3) either in a first position in which the one or more rear wheels (RW) are arranged to touch the floor (F), or in a second position in which the one or more rear wheels (RW) are arranged to be lifted from the floor (F). A vacuum cleaner advantageously comprises such a nozzle.

摘要： A brush, rotatably arranged in a cleaning device for cleaning surfaces, is described. The brush includes a core element and brush elements arranged on the core element. The brush elements are arranged in a bristle field extending in a direction of a longitudinal axis of the brush and in a peripheral direction about the longitudinal axis. Further, the brush elements include fiber hairs. Furthermore, a linear mass density of at least tip portions of the brush elements is lower than 15 g per 10 km. In addition, an average of a packing density of the brush elements in the bristle field is lower than 15,000 brush elements per 1 cm2 so as to ensure that for the purpose of moving the brush during a cleaning action, only a relatively small amount of energy is needed.

摘要： A cleaning device for cleaning a surface is described. The cleaning device includes at least one cleaning element and a wetting system to supply a cleaning liquid to the at least one cleaning element. The wetting system is operable in one of at least one normal operation mode and a boost operation mode involving an increased supply rate of the cleaning liquid with respect to the at least one normal operation mode. During start-up of the cleaning device in a wet cleaning mode thereof, a start-up operation mode of the wetting system is determined to be one of the normal operation mode or the boost operation mode on the basis of assessment of an actual value of at least one parameter that is indicative of whether or not the at least one cleaning element is in a wet cleaning condition.

摘要： A cleaning device designed to clean a surface includes a cleaner nozzle to face the surface to be cleaned and to perform a cleaning action on the surface, where the cleaner nozzle accommodates at least one rotatably arranged brush including flexible brush elements having tip portions which are intended to contact the surface. The cleaning device includes a force-actuable mechanism that is responsive to a change of a user force on the cleaning device acting to press the cleaner nozzle against the surface when the cleaner nozzle is in an operational position on the surface, and that is functional to cause a change of a value of at least one parameter of operation of the cleaning device, thereby enabling more intuitive handling of the cleaning device by a user.

摘要： A vacuum cleaner utensil comprises a plurality of elements (Lx) flexibly mounted to a central area (C) to provide a suction opening at a side of the central area (C) corresponding to a current movement direction (MD) of the vacuum cleaner utensil out of a plurality of possible movement directions, while reducing a possibility for air to enter the central area (C) from a plurality of other directions. The central area (C) may rotate around its 5 center. The elements (Lx) may rotate with reference to respective axes (A) provided on the central area (C). The elements may be mounted to a single axis (Ac), and have a flexible first part having a first thickness, followed by a second part having a second thickness exceeding the first thickness, wherein—when pushed together as a result of movement—the second parts of neighboring elements (Lx) reduce a possibility for air to enter the central area (C) from 10 between the neighboring elements (Lx). The elements (Lx) may be arranged for collecting dirt from crevices (CV) over an entire operating diameter (D) of the vacuum cleaner utensil as defined by the elements (Lx). The invention also relates to a vacuum cleaner comprising a nozzle formed by such a vacuum cleaner utensil, and may relate to a robot vacuum cleaner formed by such a vacuum cleaner utensil.15
