International Classification:

F41A 29/00
B08B 9/053
B08B 9/04

Abstract:

A bore cleaner for a tank that literally crawls through the bore of the tank, and in the process of crawling through the bore, cleans the interior walls of the bore with very little user intervention or monitoring. The bore cleaner extends and retracts as it moves through the bore of the tank, and as it extends and retracts, brushes on the present invention rub against the inside of the bore of the tank and remove debris. When the bore cleaner reaches one end of the bore of the tank, slight user intervention is necessary to reverse the direction of the brushes on the bore cleaner.
