Abstract: A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.

Abstract: A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner includes a suction inlet that introduces the air into the body and a first cyclone in the body. The first cyclone separates foreign substances from the air introduced into the suction inlet. The vacuum cleaner includes a dust separation module having a filter unit that separates foreign substances from the air introduced from the first cyclone. The dust separation module also includes a second cyclone arranged within and separated from the filter unit. The second cyclone includes a cyclone base, a storage unit arranged adjacent to a lower portion of the second cyclone, and a cyclone array coupled to the cyclone base. The cyclone array allows the air to pass through an upper portion of the second cyclone and discharge the foreign substances collected by the second cyclone to the storage unit.
