Abstract: An industrial sweeper operates by rolling along a floor to be cleaned, pushed or pulled, including: a brush with a horizontal axis depending on the use position of the industrial sweeper on a horizontal floor, a collecting pan for collecting dirt swept by the brush, the collecting pan mounted and able to pivot between a closed and working position and a wide open position allowing the pan to be emptied, a suction turbine downstream of the collecting pan suctioning dust into the collecting pan when in closed position, two wheels for resting on the floor, an air filter, an unclogging mechanism for unclogging the air filter. The air filter is fixed on the collecting pan and the unclogging mechanism includes an end stop to block travel of the collecting pan in its wide open position, the end stop causing a shock at the end of the collecting pan opening movement.
