| 摘要 |
This document discusses, among other things, a cleaning apparatus including a housing, at least one fan contained within the housing, a suction inlet in communication with a low pressure side of the fan and defining a suction flow path extending into the suction inlet, and a gas outlet proximate the suction inlet, the gas outlet defining a gas outlet flow path extending in or near the suction flow path. An example method includes blowing a gas from an apparatus toward a particulate matter and lifting the particulate matter off a surface, drawing the particulate matter into the apparatus, and collecting the particulate matter in the apparatus.
