Abstract: A vacuum cleaner including a vacuum motor configured to draw an air flow through an air flow path of the vacuum cleaner; a dirt separator having dirt, receptacle; a display screen; and a controller configured to control images displayed on the screen. The dirt receptacle has a closed configuration in which it can receive dirt separated from the air flow, and an open configuration in which dirt contained in the dirt receptacle can be emptied therefrom. The controller is configured to display video instructions on the screen.

Abstract: A vacuum cleaner includes: a vacuum motor; one or more time of flight sensors configured to generate first sensor signals dependent on the proximity of an object to the one or more time of flight sensors; a capacitive sensor located in proximity to a handle of the vacuum cleaner and configured to generate second sensor signals dependent on whether a user is gripping the handle; and a controller configured to: process the generated first and second sensor signals to determine whether the vacuum cleaner is actively being used by the user; and in response to determining that the vacuum cleaner is actively being used, activate the vacuum motor.

Abstract: A vacuum cleaner includes: a plurality of sensors configured to generate sensor signals; a vacuum motor; and a controller comprising first and second modules, wherein: the first module is configured to process the generated sensor signals to generate a plurality of control signals; the second module is configured to process the plurality of control signals to generate an output signal indicating that the vacuum cleaner is currently being used; and the vacuum motor is configured to activate or deactivate in dependence on the output signal.

Abstract: A vacuum cleaner is provided for cleaning a surface. The vacuum cleaner includes a main body, a tool, a projection surface, and a projector. The tool has a connector end for connection to the main body and a cleaner end opposite the connector end. The projection surface is provided on the tool, for displaying projected information thereon. The projector is configured for casting a projection including the projected information onto the projection surface.

Abstract: A vacuum cleaner including a vacuum motor configured to draw an air flow through an air flow path of the vacuum cleaner; a dirt separator having dirt, receptacle; a display screen; and a controller configured to control images displayed on the screen.

Abstract: A handheld vacuum cleaner includes a pistol grip which is positioned generally transverse to a longitudinal axis of the vacuum cleaner that runs from a front end to a rear end thereof. It also includes an air inlet positioned forward of the pistol grip, and a vacuum motor configured to draw dirty air into a dirt separator of the vacuum cleaner through the air inlet and exhaust clean air from the vacuum cleaner through an air outlet. The handheld vacuum cleaner further includes an electronic visual display which faces generally rearwards. The handheld vacuum cleaner may be part of a stick vacuum cleaner.
