First Claim
Patent Images
1. A surface cleaning head comprising:
- (a) a front end, a rear end and first and second opposed lateral sides;
(b) a main body having an entrance to an enclosed air flow passage and a front portion that extends forwardly from the enclosed air flow passage, the front portion having a central brushless, planar portion and laterally spaced apart side portions that extend to the first and second opposed lateral sides such that, when the surface cleaning head is positioned on a surface to be cleaned, a lower surface of the front portion is spaced from and faces the surface to be cleaned; and
,(c) an air flow passage extending from the front end to an air outlet, the air flow passage includes an open lower sided passage located between the lower surface and the surface to be cleaned when the surface cleaning head is positioned on the surface to be cleaned that extends concurrently horizontally and rearwardly to the entrance to the enclosed passage,wherein each side portion has a depending wall that extends downwardly from the central portion and is angled rearwardly and inwardly to define a sidewall of the open sided passage.

15. A surface cleaning head comprising:
-
(a) a front end, a rear end and first and second opposed lateral sides; (b) a main body having an entrance to an enclosed air flow passage and a front portion that extends forwardly from the enclosed air flow passage, the front portion having a central brushless, planar portion and laterally spaced apart side portions that extend to the first and second opposed lateral sides such that, when the surface cleaning head is positioned on a surface to be cleaned, a lower surface of the front portion is spaced from and faces the surface to be cleaned; and
,(c) an air flow passage extending from the front end to an air outlet, the air flow passage includes an open lower sided passage located between the lower surface and the surface to be cleaned when the surface cleaning head is positioned on the surface to be cleaned that extends generally horizontally and rearwardly to the entrance to the enclosed passage, wherein the open sided passage extends rearwardly to a laterally extending passage that extends transverse to a forward direction of travel and has a lower extent that is open, the laterally extending passage is provided between a forward depending wall that is located rearward of the side portions and a rearward depending wall, and extends to each laterally opposed side. - View Dependent Claims (16)

17. A surface cleaning head comprising;
-
(a) a front end, a rear end and first and second opposed lateral sides; (b) a front portion having a central portion and laterally spaced apart side portions, the side portions extending inwardly from the laterally opposed sides, each of the central and side portions having a lower rigid planar surface that is spaced from and faces a floor when the surface cleaning head is positioned on the floor with the lower surface of the side portions located closer to the floor than the lower surface of the central portion, the central portion extends rearwardly from the front end and the side portions are defined by depending walls located at the lateral sides of the lower surface of the central portion that extend rearwardly and laterally inwardly whereby the central portion has a lateral width that decreases in a rearward direction; (c) a laterally extending passage positioned rearward of the front portion, the laterally extending passage extending transverse to a forward direction of travel and has a lower extent that is open, the laterally extending passage is provided between a forward depending wall that is located rearward of the side portions and the central portion and a rearward depending wall, and extends to each laterally opposed side; and
,(c) an air flow passage extending from the front end to an air outlet, the air flow passage includes an open lower sided passage located between the lower surface of the central and side portions and the surface to be cleaned when the surface cleaning head is positioned on the floor. - View Dependent Claims (18, 19, 20, 21, 22)
