Abstract: In general, the present disclosure is directed to a force-sensing arrangement for use in surface cleaning devices, such as a vacuum device, that allows a user-supplied force to be translated into a command signal to cause the surface cleaning device to accelerate forward, reverse or to veer/turn in a desired direction. In an embodiment, the surface cleaning device includes a nozzle, wheels, motor(s) to drive the wheels, and an upright handle portion. The surface cleaning device includes a force-sensing arrangement with load cells coupled at a position where user force is transferred from the upright portion to the nozzle. The force-sensing arrangement detects the user supplying a relatively small amount of force and translates the same into measurement signals. A controller coupled to the load cells utilizes the measurement signals to determine or “infer” a desired direction of travel.

Abstract: In general, the present disclosure is directed to a hand-held surface cleaning device that includes circuitry to communicate with a robotic surface cleaning device to cause the same to target an area/region of interest for cleaning. Thus, a user may utilize the hand-held surface cleaning device to perform targeted cleaning and conveniently direct a robotic surface cleaning device to focus on a region of interest. Moreover, the hand-held surface cleaning device may include sensory such as a camera device for extracting three-dimensional information from a field of view. This information may be utilized to map locations of walls, stairs, obstacles, changes in surface types, and other features in a given location. Thus, a robotic surface cleaning device may utilize the mapping information from the hand-held surface cleaning device as an input in a real-time control loop, e.g., as an input to a Simultaneous Localization and Mapping (SLAM) routine.
