Robotic vacuum cleaning system

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.
