  • Patent number: 11019968
    Abstract: 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).

  • Patent number: 9901233
    Abstract: In a method of monitoring pollution of an air filter (Filt1) in a device in which an air flow (A) generated by a fan (F) engaged by a motor (M) passes the air filter (Filt1), the pollution is determined using data representative of a pressure difference (D2) over the fan (F), a pressure difference (D1) over the air filter, and a motor current (I) to the motor (M). The method comprises the steps of: estimating a flow through the air filter from data representative of the pressure difference (D2) over the fan (F), and the motor current (I) to the motor (M), estimating a filter resistance of the air filter from data representative of the flow through the air filter, and the pressure difference (D1) over the air filter, and estimating the pollution of the air filter from data representative of the filter resistance of the air filter.

  • Patent number: 9854951
    Abstract: A vacuum cleaner head has a base and a suction opening in the base. An array of flexible flaps protrudes from the base. The flexible flaps are configured to act on a surface to be cleaned. The flexible flaps are spaced from each other to allow the passage of detritus therebetween in a predefined arrangement. The predefined arrangement of the flexible flaps is configured to promote a non-linear flow path through the array of flexible flaps between an end of the base and the suction opening. A gap between first and second rows of flaps is substantially equal to or greater than a space between adjacent flexible flaps in each of the first and second rows.
