| 20080201898 | SELF-CLEANING FILTER ARRANGEMENT WITH ACTIVATION SIGNAL FOR FLOOR CARE APPARATUS - A floor care apparatus has a filter with an intake and out take. A first pressure sensor is arranged on the intake while a second pressure sensor is arranged on the out take. A controller connects to the sensors to receive signals indicative of relative pressure. Whenever a predetermined pressure differential between the signals is achieved, an undesirable load on the filter is deemed occurred and initiation of a self-cleaning of the filter begins. In this manner, filter cleaning only occurs on an as-needed basis and user intervention is avoided, thereby adding convenience. The controller is also able to ascertain a clogged airway condition. Various features contemplate pressure sensor signals arranged to scale suction as positive pressures, meeting the predetermined pressure differential at other than a maximum pressure differential between the first and second pressure sensors, and scaling the predetermined pressure differential relative to the maximum pressure differential. | 08-28-2008 |
