    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.

    Abstract: A cleaning apparatus includes an end cap assembly for use with an agitator. The end cap assembly includes a stationary end cap, a rotating end cap, and a fragmentor. The stationary end cap is secured to and stationary with respect to a housing of the cleaning apparatus. The rotating end cap is coupled to the agitator and rotates with the agitator relative to the housing. The stationary and rotating end caps define a gap extending radially inward therebetween. The fragmentor is disposed within the gap and is configured to break debris which enters the gap into smaller pieces. The fragmentor may be disposed on a surface of the stationary end cap facing towards the rotating end cap and/or on a surface of the rotating end cap facing towards the stationary end cap. The fragmentor may include a cutting blade and/or an abrasive surface.
