Vacuum cleaner
First Claim
1. A vacuum cleaner having:
- a blower for creating suction,an electric motor for driving said blower,an electric motor actuation circuit electrically connected to said electric motor,a dirt collection container,a body, housing said electric motor, said electric motor actuation circuit, said dirt collection container, and said blower, and having defined therein a suction port, an exhaust port, and a suction passage extending therethrough from said suction port to said exhaust port; and
a hose connected at a first end of said body, said hose having a handle at a second end thereof, said handle having a control for actuating said motor, said hose further having hose conductors connected to said control and extending to said first end, and first electrical contact members connected to said hose conductors at said first end;
wherein;
each one of said suction port and said exhaust port comprises respective second electrical contact members for mating with said first electrical contact members when said hose is connected to a respective one of said suction port and said exhaust port, said respective second electrical contact members being connected to said electric motor actuation circuit for actuating said motor in response to user actuation of said control.

Abstract
A canister-type vacuum cleaner is provided in which various electrical functions of the vacuum cleaner may be controlled by the user with controls on the hose handle, whether the hose is attached to the suction port or the blowport. The primary exhaust port is located substantially toward the front of the vacuum cleaner body. During normal operation, air is directed from the hose through the suction port and the motor, toward the back of the vacuum cleaner, and then redirected to the front of the vacuum cleaner, where it exits from the primary exhaust port. The vacuum cleaner is also provided with a reduced wheelbase, for greater maneuverability. Two wheels are mounted on the underside of the vacuum cleaner body, near the vacuum cleaner'"'"'s center of gravity, and a caster is mounted near the front of the vacuum cleaner. The vacuum cleaner can therefore be rotated about an axis passing adjacent the cleaner'"'"'s center of gravity and perpendicular to the surface being cleaned, as well as an axis passing between the two wheels. Additional casters may be mounted on the underside and toward the back of the vacuum cleaner body, for additional stability.
