    Abstract: A vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator, and an illumination system. The agitator is rotatably disposed at least partially within the agitation chamber and includes an agitator body defining an illumination chamber. The illumination system is at least partially disposed within the illumination chamber and includes at least one light source. Alternatively, a vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator rotatably disposed at least partially within the agitation chamber, an illumination coupled to the vacuum body and including at least one light source, and a light guide configured to redirect light emitted in a first direction from the at least one light source to a second direction.

    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: An example of a robotic cleaner, consistent with the present disclosure, may include a body, an agitator chamber defined in the body, a suction motor fluidly coupled to the agitator chamber and configured to cause air to flow into the agitator chamber, and at least one air jet assembly coupled to the body, the air jet assembly being configured to generate an air jet, the air jet being configured to urge debris toward the agitator chamber.
