AI summary

A vacuum cleaning system comprising a robotic unit (2) including a traction arrangement, and a docking interface (84) for receiving a handheld vacuum cleaner (6), and a handheld vacuum cleaner configured to be docked with the docking interface. The handheld vacuum cleaner (6) comprises a vacuum motor for drawing air through a suction flow path defined by the robot unit when docked with the docking interface, wherein the handheld vacuum cleaner comprises a main body from which extends a battery pack (26). 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. Advantageously, the invention provides a particularly user friendly cleaning system for a user who is able to use the handheld vacuum cleaner for spot cleaning or larger cleaning tasks, but is then able to dock the handheld vacuum cleaner onto the robotic unit for autonomous cleaning tasks. Advantageously, the configuration of the battery pack extending over the main body of the robotic unit means that a relatively heavy component is held close to a central position over the main body which is helpful for mass distribution as the machine moves around the floor. 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. The suction tools may be passive, that is without a motorised bush bar or agitator, such as may be the case for floor tools optimised for hard floors, or the suction tools may be motorised which makes them particularly suited to piled floor coverings such as carpets and rugs.
