1. A vacuum comprising:
- a handle;
a yoke to receive the handle;
a base distinct from the yoke; and
an axle connected to the yoke, wherein the yoke provides a moment arm anterior to the base,wherein the moment arm is anterior to the base,wherein the base comprises a lifting device that raises the base off a cleaning surface, andwherein the lifting device comprises a biasing device to keep the lifting device receded into the base and a ramp to expel the lifting device from the base when the handle is placed in a locked position.

Abstract
A vacuum cleaner with a reduced frictional force between a vacuum base and a cleaning medium is described. The vacuum has a handle, yoke, body, and base. A handle and yoke distinct from, and behind, the base provides a moment arm anterior to the base when a force is applied. The handle and yoke assembly reduce the friction between the cleaning surface and the vacuum, allowing for larger motor and debris capturing capabilities, with easier handling and maneuverability resulting in advanced and superior cleaning capabilities.

17. A method of reducing the frictional force between a vacuum base and a cleaning medium, the method providing a vacuum comprising:
-
providing a handle, a yoke to receive the handle, a base distinct from the yoke, an axle connected to the yoke, to the wherein the moment arm is anterior to the base; disposing the yoke to provide a moment arm anterior to the base; applying a force to the handle which causes the yoke to be pushed towards a cleaning surface thereby reducing a frictional force of the base against a cleaning surface, raising the base off a cleaning surface when the handle is placed in a locked position; receding a lifting device into the base when the handle is placed in an unlocked position; and expelling the lifting device from the base when the handle is placed in a locked position.

18. A method of reducing the frictional force between a vacuum base and a cleaning medium, the method providing a vacuum comprising:
-
providing a handle, a yoke to receive the handle, a base distinct from the yoke, an axle connected to the yoke, wherein the moment arm is anterior to the base; disposing the yoke to provide a moment arm anterior to the base; applying a force to the handle which causes the yoke to be pushed towards a cleaning surface thereby reducing a frictional force of the base against a cleaning surface, expelling dirty airflow from the base with an airflow duct distinct from the handle; providing a dirt collecting device connected to the airflow duct; sliding the dirt collecting device along a longitudinal axis of the handle; and
raising the base off a cleaning surface when the handle is placed in a locked position;
receding a lifting device into the base when the handle is placed in an unlocked position; and
expelling the lifting device from tile base when tile handle is placed in a locked position. - View Dependent Claims (19, 20, 21)
