Abstract: A vacuum cleaning system including a robotic unit including a traction arrangement that defines a ground plane, and a docking interface for receiving a handheld vacuum cleaner. The docking interface defines a suction port, an electrical port, and a predefined interface geometry. The docking interface is reconfigurable from a first configuration for engaging with a first handheld vacuum cleaner, and a second configuration for engaging with a second handheld vacuum cleaner which is different to the first handheld vacuum cleaner. Conveniently, the system includes a robotic unit or module that is dockable or engageable with multiple handheld vacuum cleaners, thus allowing some flexibility with the type of machine that they are able to use with the robotic unit. This provides a cost effective solution for the user, because if the user upgrades their handheld vacuum cleaner that new handheld vacuum cleaner can still be used with the robotic unit.

Abstract: A vacuum cleaning system including a robotic unit including a traction arrangement, a docking interface and an articulated arm defining an end effector. The end effector includes a suction tool. The robotic unit defines a suction flow path which extends from the suction tool to the docking interface. The system further includes a handheld vacuum cleaner configured to be docked with the docking interface, the handheld vacuum cleaner including a vacuum motor for drawing air through the suction flow path when docked with the docking interface.

Abstract: A vacuum cleaning system including a robotic unit including a traction arrangement, and a docking interface for receiving a handheld vacuum cleaner, and a handheld vacuum cleaner configured to be docked with the docking interface. The handheld vacuum cleaner includes a vacuum motor for drawing air through a suction flow path defined by the robot unit when docked with the docking interface. The handheld vacuum cleaner includes a main body from which extends a battery pack. When the handheld vacuum cleaner is docked with the docking interface, it is configured such that the battery pack extends over the top of at least part of the robotic unit. Conveniently, the robotic unit and the handheld vacuum cleaner may share one or more common suction tools, which means that both machines can be optimised for the surfaces they are intended to clean.

Abstract: A vacuum cleaning system including a robotic unit including a main body, a traction arrangement defining a ground plane, and an articulated arm. The articulated arm includes an upper arm section and a lower arm section, wherein the upper arm section is attached to the main body at a shoulder joint, and wherein the lower arm section is attached to the upper arm section at an elbow joint, and wherein an end effector is defined at a distal end of the lower arm section. The articulated arm is configured such that the end effector is movable angularly about a first axis with respect to the elbow joint and is movable linearly along a second axis with respect to the elbow joint. The vacuum cleaning system equipped with a robotic arm that is able to bend and flex due to the pivotable upper and lower arm portions, but also extend and rotate through the lower arm or ‘forearm’ portion, providing improved dexterity for the machine.

Abstract: A wand and hose assembly for a vacuum cleaner includes a suction wand fluidly connected to the end of a suction hose by a duct and the duct incorporates an articulating joint for allowing articulated movement of the suction wand relative to the end of the suction hose. The wand and the duct are arranged for telescopic sliding movement relative to one another, and the articulating joint is moveable into a position in which the wand can slide telescopically through the duct for retraction into the suction hose.

Abstract: An upright vacuum cleaner comprising a vac-motor for drawing dirty air in through a floor-engaging cleaner head on the vacuum cleaner, a separating apparatus for separating dirt from the dirty air, an elongate air duct for carrying air to or from the separating apparatus, and a suction wand which is stored on the vacuum cleaner and which can be connected to the separating apparatus via a hose as required to clean above the floor. The external surface of the air duct defines an elongate recess for receiving the stored suction wand such that the air duct partly surrounds the stored wand. This provides a compact configuration.

Abstract: A cleaning appliance of the cylinder type comprises a separating apparatus for separating dirt from a dirt-bearing fluid flow, and a floor-engaging rolling assembly. The separating apparatus comprises a first cyclonic separation unit having a low efficiency cyclone and a second cyclonic separation unit having a plurality of second cyclones. The rolling assembly comprises a main body and a pair of floor-engaging wheels. The main body comprises a recess in which the separating apparatus is received such that when the cleaning appliance is viewed from either side there is no gap between the first cyclonic separation unit and the rolling assembly along at least 50 to 100% of the full length of the low efficiency cyclone.

Abstract: An upright vacuum cleaning appliance includes a main body having a user operable handle, separating apparatus for separating dirt from a dirt-bearing air flow and a casing housing a fan unit for drawing the air flow through the separating apparatus. A support assembly is connected to the main body for allowing the appliance to be rolled along a surface using the handle. The support assembly includes a pair of domed-shaped wheels which each have a substantially circular rim. The overall size of the appliance is reduced by locating the casing between the wheels, and providing an air duct which extends between the rims of the wheels to convey the air flow from the separating apparatus to the casing.
