Vacuum cleaner brushroll cleaner configuration
First Claim
1. A vacuum cleaner head comprising:
- a housing having a front end, a back end spaced from the front end, a lower surface extending between and joining the front end to the back end, and a suction opening through the lower surface and proximate the front end;
an agitator chamber located above and in fluid communication with the suction opening;
a suction passage extending from the agitator chamber towards the back end of the housing;
an agitator comprising a spindle rotatably mounted to the housing to rotate about a rotation axis that extends through the agitator chamber, one or more agitating devices positioned between a first end of the agitator and a second end of the agitator projecting from the spindle to a first radial height one or more friction surfaces that extend to a second radial height;
a cleaning member comprising one or more edges that extend parallel to the rotation axis from the first end of the agitator to the second end of the agitator, the one or more edges being movably mounted to the housing to move between a first cleaning member position in which the one or more edges do not engage the agitator, and a second cleaning member position in which the one or more edges engage at least one of the one or more friction surfaces on the agitator to remove debris from the agitator during rotation of the agitator; and
a pedal extending from the back end of the housing, the pedal being movable between a first pedal position in which the pedal does not place the cleaning member in the second cleaning member position, and a second pedal position in which the pedal places the cleaning member in the second cleaning member position.

Abstract
A vacuum cleaner head with a housing having a front end, a back end, a lower surface extending from the front end to the back end, and a suction opening through the lower surface. An agitator chamber is the suction opening, and a suction passage extends from the agitator chamber towards the back end. An agitator having a spindle and agitating devices is rotatably mounted to the housing. A cleaning member is movably mounted to the housing to move between a first position in which it does not engage the agitator, and a second position in which it engages the agitator to remove debris from the agitator during rotation of the agitator. A pedal extends from the back end of the housing and moves between a first pedal and a second pedal position to place the cleaning member in the second cleaning member position.
