Abstract
The improved vacuum cleaner is a recirculating type vacuum cleaner with a suction mechanism, air retrieving passageway, and dirt collecting member, that has an detachable nozzle formed as an elongated hollow hose that is attached between the exhaust port on the surface of the vacuum body and an inlet on the vacuum head. The nozzle is adapted to push air downward onto the surface to be vacuumed to dislodge dirt and particles in the surface where the air and dirt into air retrieving opening on the vacuum head.
Claims17
An improved vacuum cleaner comprising:
- a body and head;
- an air retrieving passageway, the air retrieving passageway having a first end connected to the head and a second end connected to the body, the air retrieving passageway configured to receive air and dirt from an air retrieving opening within the head;
- a dirt collecting member attached within the body;
- an exhaust port positioned on a surface of the body, the exhaust port configured to allow air to exit the body after passing through the air retrieving opening and the dirt collecting member;
- a suction mechanism;
- wherein the suction mechanism is attached within the body, the suction mechanism configured to suck air and dirt into the air retrieving opening and then into the dirt collecting member, the suction mechanism including a motor to drive a fan to create a negative pressure wherein when the negative pressure is created, the fan expels air from behind the fan, creating back-pressure that pushes air and dirt downward through the body, the dirt collecting member configured to receive air and dirt passing through the air retrieving opening that is pushed down by the back-pressure of the suction mechanism and downwards gravity;
- and
- a nozzle;
- the nozzle located outside the body, the nozzle having a first end detachably coupled to the exhaust port, the nozzle having a second end detachably coupled to the head, the nozzle configured to push air from the exhaust port out through an air pushing opening within the head and into the air retrieving opening.

A method for pushing and collecting dirt comprising:
- a providing a vacuum, the vacuum having a housing, the housing including a body and head;
- an air retrieving passageway, the air retrieving passageway having a first end connecting to the head and a second end connecting to the body, the air retrieving passageway configured to communicate with an air retrieving opening within the head, a dirt collecting member attaching within the body;
- an exhaust port positioned on a surface of the body, the exhaust port allowing air to exit the body after passing through the air retrieving opening and the dirt collecting member;
- a suction mechanism, wherein the suction mechanism is attached within the body, the suction mechanism sucking air and dirt into the air retrieving opening and then into the dirt collecting member, the suction mechanism including a motor to drive a fan to create a negative pressure wherein when the negative pressure is created, the fan expels air from behind the fan, creating back-pressure that pushes air and dirt downward through the body, the dirt collecting member receiving air and dirt passing through the air retrieving opening that is pushed down by the backpressure of suction mechanism and downwards gravity;
- and
- detachably coupling a nozzle to the vacuum, the nozzle located outside the body, the nozzle having a first end detachably coupled to the exhaust port, the nozzle having a second end detachably coupled to the head, the nozzle pushing air from the exhaust port out through an air pushing opening within the head and into the air retrieving opening.

An improved upright vacuum cleaner comprising:
- an air retrieving passageway, the air retrieving passageway an elongated tube;
- a nozzle, the nozzle an elongated tube;
- a vacuum head, the vacuum head having an inlet for receiving the nozzle and the air retrieving passageway;
- and
- the air retrieving passageway having a first end detachably coupled to an air retrieving opening in the vacuum head;
- the air retrieving passageway having a second end configured to connect to a vacuum body;
- the nozzle having a first end detachably coupled to an air pushing opening in the vacuum head, the nozzle having a second end configured to connect to an exhaust port of the vacuum body, the exhaust port configured for pressurized air to be pushed from the exhaust port through the nozzle to the vacuum head to dislodge particles on a surface.
