DorotheeMW1 year ago000My L20, bought in December, leaves piles of dirt behind when vacuuming. Sensors and brush have been cleaned, bag changed. What should I do?Show in original language (German)Severin821 year ago • purchased this product000purchased this product Helpful answerThe trandparent dust container in the robot is clogged.
