Device for cleaning heavily contaminated tanks, basins, pipes and containers, has two slanted rotating attachments, such as brushes, chain runs and belt loops as cleaning features

摘要

The device has two slanted rotating attachments, such as brushes, chain runs and belt loops as cleaning features. The impurities are cleared by suction by the cleaning features in the centrally arranged transport. The running speed of two drives of the attachments is controlled at different speeds for directing the device to the left or right. The rotating attachments are guided along the suction device for cleaning, so that the area is kept free for sucking larger objects, such as stones or lumps to prevent clogging.
