A baghouse cleaning system comprises an elongated air accumulator configured to retain pressurized air and extend over a row of filter bags. An elongated air tube extends along the air accumulator and venturis extend from the air tube. The venturis blow pressurized air streams down into the filter bags to remove particles attached to an outside filter bag surface. A valve fluidly couples the air accumulator to the air tube and an actuator is configured to move the cleaning arm linearly over different rows of the filter bags. A sensor may determine when the filter bags need to be cleaned based on a measured air pressure. A controller can actuate the cleaning arm to clean the filter bags based on preprogrammed cleaning patterns, the amount of measured air pressure, and/or other detected environmental conditions.
