Abstract
A mobile sweeper includes an air blast pickup head having air intake and exhaust ports communicating with the exhaust of a blower and the input of a debris plenum, respectively, for suctioning debris from a surface being cleaned and depositing the debris in the debris plenum. In order to control the dust caused by the air movement, a source of pressurized water is injected in the form of minute droplets into the air stream in advance of the pickup head air intake and in advance of the debris plenum input.
