  • Patent number: 11039722
    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.

  • Patent number: 9943199
    Abstract: This invention relates to a hand-held vacuum cleaner (10). The vacuum cleaner is expected to have particular utility for cleaning locations which are difficult to reach with a conventional vacuum cleaner. The vacuum cleaner (10) has a body (12) with a substantially planar base (22) upon which the vacuum cleaner can rest when not in use, the body having a carrying handle (20), a motor (14) and an impeller (16) located within the body, the vacuum cleaner also having a collector (26, 126) and a battery pack (18), the battery pack providing at least a part of the base (22). The motor and the battery pack are located between the base and the collector so as to lower the center of gravity and make the vacuum cleaner more comfortable for use, especially over long periods. Ideally, the center of gravity is close to the carrying handle, and between the carrying handle and the nozzle so that the vacuum cleaner is slightly “nose heavy”.

    Abstract: A vacuum cleaner includes a base having a foot with a suction nozzle and a handle assembly removably coupled to the foot. The handle assembly is movable between a first position, in which the handle assembly is connected to the foot, and a second position, in which the handle assembly is disconnected to the foot. The vacuum cleaner also includes a canister assembly supported by the base. The canister assembly is removable from the base. The vacuum cleaner further includes a latch supported by one of the foot and the handle assembly. The latch is engageable with the other of the foot and the handle assembly to selectively secure the handle assembly to the foot. The latch is inaccessible when the canister assembly is supported by the base.
