ABSTRACT:
A method and a washing machine for cleaning of rugs or mats having a nap or pile side, whereby the rugs or mats are successively conveyed along a conveying path and are exposed to cleaning operations, at least one of which is a pulsating operation, during which each mat or rug is also exposed to a relatively abrupt change of direction of conveyance in order to open an area of pile at the pile side of the mat or rug. The change of direction preferably has a radius of curvature in a range between 1.5 cm and 15 cm during an angular change of direction of approximately 180 degrees. The cleaning fluid used in one operation is for saving of energy preferably used also in another earlier cleaning operation on the mats or rugs, possibly after having been conditioned for this earlier operation.
