Abstract

A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.

Claims

1. A surface cleaning head comprising:

a housing having a front side, a back side, a first lateral side and a second lateral side, the housing defining a suction conduit with a suction conduit opening on an underside of the housing between the front side and the back side;

a brush roll rotatably mounted to the housing within a brush roll chamber, wherein the suction conduit passes through the brush roll chamber and at least a portion of the brush roll is proximate the opening of the suction conduit;

a leading roller mounted to the housing in front of the brush roll;

a removable cover removably coupled to the housing for covering the brush roll chamber and the brush roll and at least partially covering the leading roller; and

at least one latching mechanism configured to engage the removable cover to removably couple the cover to the housing, wherein the latching mechanism includes a latch finger configured to engage the removable cover proximate the front of the housing when the removable cover is coupled to the housing and a latch actuator configured to retract the latch finger and release the cover.

2. The surface cleaning head of claim 1 wherein the latching mechanism includes first and second latching mechanisms proximate the first lateral side and the second lateral side, respectively.

3. The surface cleaning head of claim 1 wherein the latching mechanism is isolated from the brush roll chamber.

4. The surface cleaning head of claim 1 wherein the removable cover includes at least one tab extending from the back portion of the removable cover for engaging the housing.

5. The surface cleaning head of claim 1 wherein the removable cover includes a seal that engages a perimeter of the housing around the brush roll chamber.

6. The surface cleaning head of claim 1 wherein the leading roller is removable when the removable cover is removed.

7. The surface cleaning head of claim 6 wherein the removable cover engages at least one end of the leading roller and holds the leading roller in the housing.

8. The surface cleaning head of claim 1 wherein the removable cover is completely removable from the housing.

9. The surface cleaning head of claim 1 wherein the removable cover includes a bumper located at the front side of the housing when the removable cover is coupled to the housing.

10. The surface cleaning head of claim 9 wherein the bumper includes at least a portion that extends in front of the leading roller.

11. The surface cleaning head of claim 1, wherein the leading roller includes a cleaning element that is softer than a cleaning element of the brush roll.

12. The surface cleaning head of claim 1, wherein the leading roller has a smaller diameter than the brush roll.

13. The surface cleaning head of claim 1, wherein the brush roll includes at least one arrangement of shorter stiffer bristles and at least one arrangement of longer softer bristles, wherein the longer softer bristles are longer and softer as compared to the shorter stiffer bristles.

14. A surface cleaning head comprising:

a housing having a front side, a back side, a first lateral side and a second lateral side, the housing defining a suction conduit with a suction conduit opening on an underside of the housing between the front side and the back side;

a brush roll rotatably mounted to the housing within a brush roll chamber, wherein the suction conduit passes through the brush roll chamber and at least a portion of the brush roll is proximate the opening of the suction conduit;

a leading roller mounted to the housing in front of the brush roll;

a removable cover removably coupled to the housing for covering the brush roll chamber and the brush roll and at least partially covering the leading roller; and

at least one latching mechanism configured to engage the removable cover to removably couple the cover to the housing, wherein the latching mechanism includes a latch finger configured to engage the removable cover proximate the front of the housing when the removable cover is coupled to the housing and a latch actuator configured to retract the latch finger and release the cover.

15. A surface cleaning head comprising:

a housing having a front side, a back side, a first lateral side and a second lateral side, the housing defining a suction conduit with a suction conduit opening on an underside of the housing between the front side and the back side;

a brush roll rotatably mounted to the housing within a brush roll chamber, wherein the suction conduit passes through the brush roll chamber and at least a portion of the brush roll is proximate the opening of the suction conduit;

a leading roller mounted to the housing in front of the brush roll; and

a removable cover removably coupled to the housing for covering the brush roll chamber and the brush roll and at least partially covering the leading roller;

wherein the leading roller is removable when the removable cover is removed; and

wherein the removable cover engages at least one end of the leading roller and holds the leading roller in the housing.
