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.

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.

Determining a start-up operation mode of a wetting system of a cleaning device

In a vacuum cleaner utensil () comprising a suction opening () and a lint picker () at a side of the suction opening (), the lint picker () is mounted in a recessed portion having a plurality of rims (-) along lines at an angle between 20° and 70° to a longitudinal axis (A-A) of the suction opening () that form edges pointing towards the suction opening (). Preferably, the lint picker has a plurality of triangular-shaped elements (-). Preferably, the lint picker has a plurality of elements (-) that have first and second boundaries along lines at an angle between 20° and 70° to the longitudinal axis (A-A) of the suction opening (), an angle between the first and second boundaries not exceeding 120°. Another aspect of the invention provides a vacuum cleaner comprising a suction unit, and a nozzle arranged for being coupled to the suction unit, wherein the nozzle is formed by such a vacuum cleaner utensil ().
