First Claim
Patent Images
1. A vacuum comprising:
- a base including an air intake port;
a handle coupled to the base such that the handle is pivotable about a first axis between an upright position and an inclined position;
a suction source operable to generate an airflow that is drawn through the air intake port;
a dirt collection device configured to separate debris from the airflow; and
a scroll having an air conduit, the scroll in fluid communication with the air intake port and the dirt collection device such that the scroll directs the airflow and debris in a direction from the air intake port toward the dirt collection device,wherein the scroll is pivotably coupled to the base about a second axis that is different than the first axis.

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.
