Abstract: A cleaning device includes a cleaning device body and a replacement head. The cleaning device body includes an elongated handle, a housing and a replacement head mounting section. The replacement head has a pad that is intended to clean a surface, such as a floor and is removably attachable to the cleaning device body. The housing includes a circuit board having at least one sensor capable of sensing motion. The handle includes at least one button that can turn on/off either a vacuum source or a jet nozzle that sprays cleaner fluid. The cleaning device body further includes at least one light mounted thereon. The at least one light is illuminated when the button is pressed and then the at least one light remains illuminated until a predetermined amount of time has passed during which neither the button has not been pressed nor motion sensed by the sensor.

Abstract: The present disclosure is generally directed to techniques for radial alignment of motor components relative to each other to achieve a motor with a rotor bore having sub-micron end-to-end deviation. In an embodiment, a rotor bore alignment tool is disclosed herein that can be inserted between motor components, and more particularly, apertures/through holes defined by each of the motor components such as housing sections and a stator assembly. The rotor bore alignment tool includes expandable members that can be selectively transitioned to an extended position to cause each of the motor components to be radially aligned prior to securely coupling the same in a so-called "stack" to form a motor. Once the motor components are coupled together, the resulting motor includes a rotor shaft extending from end-to-end that preferably includes a sub-micron deviation of less than 10 microns, and more preferably less than or equal to 5 microns, for example.

Abstract: Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. A cleaning head is coupled to a body of the vacuum cleaner via one or more suspension elements that comply to horizontal oscillations of the cleaning head imparted by an offset bearing of a vertical gear drive driven by a motor mounted to the body. A vacuum source draws air in from a suction nozzle at a forward underside portion of the cleaning head adjacent to a cleaning pad, and the air travels through an air filter disposed between the vacuum source and the collection chamber. In some embodiments, the air filter comprises one or more pleats adjacent to the vacuum source.

Abstract: A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber that has a sealing surface and at least one opening. The opening is provided to allow air, dust and debris to be drawn into the dust chamber during use. The sealing surface defines a sealing surface plane and the opening defines an opening place. The relative angle between the sealing surface plane and the opening plane is preferably between about -20 degrees and +150 degrees. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.

Abstract: In general, the present disclosure is directed to nozzle control circuitry for use in surface cleaning devices that preferably reduces overall power consumption of a surface cleaning device by detecting the start of a cleaning operation by a user before energizing one or more components such as an agitator. The nozzle control circuitry can detect a cleaning operation based on data output from one or more sensors (also referred to herein as operation sensors). For example, the nozzle control circuitry can communicate with at least one of a motion sensor such as an accelerometer, an orientation sensor such as gyroscope, and/or an air pressure sensor operatively coupled within a dirty air inlet to detect the presence of generated suction.

Abstract: An adaptive sensor array system and method includes receiving one or more signals from a sensor array and compare the received signals to one or more object detection threshold values, determining if the robotic cleaner was moving along a travel path for a predetermined period of time, window W, in response to a determination that the robotic cleaner was operating in straight-line motion during the window W, calculating a value of the received detected signals from the sensor array during one or more calibration periods C of the window W, and adjusting one or more of the object detection threshold values based on the calculated value during the window W. A sum of all the calibration periods C during window W is less than a length of the window W. One of the calibration periods C may start at a beginning of the window W.

Abstract: A vacuum cleaner system includes an agitator and nozzle assembly having an agitator configured to rotate about a pivot axis and a suction tube. The agitator includes an agitator body having an agitator suction inlet and defining a suction tube chamber. The suction tube chamber extends along at least a portion of the pivot axis and includes a suction tube opening disposed at one end thereof. The suction tube is received through the suction tube opening and partially into the suction tube chamber, and includes a suction tube inlet. The agitator is configured to rotate about the pivot axis relative to suction tube such that the agitator suction inlet and the suction tube inlet partially overlap and an air flow path is established which extends through agitator suction inlet, into suction tube chamber, through suction tube inlet, and into the suction tube.
