    Abstract: A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.

    Abstract translation: 真空吸尘器附件通常包括相对于真空吸尘器附件的抽吸管道漂浮的清洁元件。 清洁元件被支撑在可移动地联接到壳体并且例如由于清洁元件支撑结构的重量的结果而被朝向地板偏置的支撑结构上。 清洁元件可以永久地附接到支撑结构，或者可以是附接到支撑结构的可移除或一次性的垫或片。 浮动清洁元件可以被支撑在吸入管道和真空吸尘器附件的一个或多个车轮之间。 真空吸尘器附件可以可移除地附接到真空吸尘器，例如可与其它表面清洁头互换使用。

    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.
