ABSTRACT:
Vacuum apparatus for sucking up pollutants with a suction mouthpiece maintained at a given distance above the ground. The mouthpiece is partially defined at least on one side by rollers guided loosely on the apparatus and held in place during operation by the vacuum created in the apparatus. The rollers enable the apparatus to operate effectively over rough ground and to pick up relatively large pollutants.
