Vacuum cleaner with improved suction inlet

In a vacuum cleaner head having a housing with a suction inlet at its bottom and a rotatable brush connected to the housing, the improvement comprising:

• the housing having a pocket in front of the suction inlet in which the rotatable brush is located, the pocket being separate from the suction inlet with a wall of the housing being located between the pocket and the suction inlet;
• at least two motors, the first one of the motors being connected to an impeller and a second one of the motors being connected to the rotatable brush;
• said suction inlet extending upward from the bottom of the housing substantially entirely perpendicular to the bottom of the housing between an entrance to the suction inlet and an exit aperture in a wall at the top of the suction inlet;
• the suction inlet having an upper section with a generally uniform shape and a lower section with a non-uniform shape;
• and
• the lower section having straight front and rear wall sections in which two of the rear wall sections uniformly taper towards the front wall section as they approach lateral ends of the suction inlet, and two straight top wall sections uniformly taper downwardly from the upper section as they extend towards the lateral ends of the suction inlet.

A vacuum cleaner floor traveling head comprising:

• a first motor;
• an impeller connected to the first motor;
• and
• a housing enclosing the motor end forming a suction inlet at a bottom of the housing, the entire suction inlet extending upward perpendicular to the bottom of the housing with an exit aperture in a wall at the top of the suction inlet;
• a rotatable brush, the housing including a pocket in the bottom of the housing and in front of the suction inlet having the rotatable brush therein, the housing having a wall separating the suction inlet from the pocket;
• the suction inlet having an upper section with a generally uniform shape and a lower section with a non-uniform shape;
• and
• the lower section is larger in cross-sectional area than the upper section and the upper section has an exit directly into a collection assembly where air velocity increases from the lower section to the upper section and then decreases from the upper section into the collection assembly.
