A dust collector with convenient loading and unloading dust collecting barrel includes a base plate fixed on an outer periphery of a bottom of an air guide cylinder, an operation unit whose end is pivotally arranged on the base plate, linking members disposed on said operation unit and connected to a dust collecting barrel lid located under the air guide tube. Accordingly, when a user lifts up the operation unit, the linking members move the dust collecting barrel lid upwards. The upward movement separates the dust collecting barrel lid from the dust collecting barrel, so the dust collecting barrel is easily detached. The action of swinging the operation unit swings down allows the linking members to move the dust collecting barrel lid downwards, so the dust collecting barrel lid closes the dust collecting barrel. Therefore, the user loads and unloads the dust collecting barrel quickly and conveniently.

A vacuum collection vehicle may include a chassis, a vacuum container, a filter unit, a first discharge conduit and a second discharge conduit. The filter unit may include a filter housing that supports a filter independent of opposing interior walls. The vehicle may include a storage container supported by the chassis and containing a vacuum source or hose reel. The vehicle may include inner and outer collection receptacle supports for supporting collection receptacles within the vacuum container.

Devices for collecting patient excretions utilize existing suction sources and facilitate the cleaning of bedding and/or a patient. Patient excretion collection devices comprise a collection reservoir and a collection wand which are attached to an existing source of suction.

The present invention pertains to a method and apparatus for cleaning soot, creosote, and other materials adhered to the interior walls of a chimney using a mobile cleaning and vacuuming unit. The apparatus is comprised of a pressurized water delivery system, a vacuum system, a chimney cleaning attachment having a plurality of spray nozzles arranged radially about a central axis, and one or more extensions. The required length and corresponding number of extensions are attached to a pressurized water delivery system as needed to access the chimney interior. The chimney cleaning attachment is mechanically affixed to the free end of the extensions and the device is lowered into a chimney. The water delivery system delivers high pressured water to the nozzle abrade the undesirable material within the chimney. A vacuum system positioned near the base of the chimney removes the water and substances that are dislodged during the washing process.

A robot cleaner includes a body, a first rotating plate, a second rotating plate, a first mop, a second mop, a first support wheel, a second support wheel, and a first lower sensor. The first lower sensor is configured to sense a relative distance from a floor. The first lower sensor is located between the first support wheel and the second support wheel, and is located further away from the first rotating plate and the second rotating plate than the first support wheel and the second support wheel. The robot cleaner may move while being supported by the first mop, the second mop, the first support wheel, and the second support wheel, and easily avoid a cliff in which the floor suddenly drops.

A dust separator including a top member having a top member having an inlet port arranged to supply dust-laden air and an outlet port arranged to remove clean air, the top member having a lower portion configured as a lip and having a radius which equals diameter of the inlet port, and a dust separator plate, housed within the lip, having a passage with at least one opening arranged to remove the dust from within the top member.

A vacuuming apparatus for collecting and disposing of sharps waste is disclosed. The sharps waste may include a used hypodermic needle. The vacuuming apparatus includes a passageway including a sidewall defining an interior chamber. The passageway includes an open suction end and an open nozzle end dimensioned to receive the sharps waste. The vacuuming apparatus includes a discharge port located at the suction end and in gaseous communication with a container, such as a used sharps container. The vacuuming apparatus includes a fan, that when operated, is configured to move air from the open nozzle end to the suction end and into the container such that the sharps waste may be moved in an airstream from a surface proximate to the open nozzle end into the container.
