11 . The vacuum cleaner according to claim 6 , wherein the at least one rib includes a first rib located on a first axial side of the first axial location and a second rib located on a second axial side of the first axial location, wherein the second rib includes a forward portion connected to the front wall, a rearward portion connected to the rear wall and turned only toward the first axial location of the outlet port to define a flow guide.
12 . The vacuum cleaner of claim 11 , wherein the first and second ribs are mirror images of each other.
13 . The vacuum cleaner according to claim 11 , wherein the rearward portion of the first rib and the rearward portion of second rib are angled toward each other.
14 . The vacuum cleaner according to claim 11 , wherein the at least one rib includes a third rib located on the second axial side of the first axial location, wherein the third rib includes a forward portion connected to the front wall, a rearward portion connected to the rear wall and angled only toward the outlet port to define a flow guide.
15 . The vacuum cleaner of claim 14 , wherein the rearward portions of the second and third ribs are parallel.
16 . The vacuum cleaner according to claim 14 , wherein the surface cleaning head includes a brushroll belt positioned at a second axial location, and wherein the second and third ribs are located on opposite sides of the second axial location.
17 . The vacuum cleaner according to claim 1 , wherein each rib of the at least one rib includes a downwardly curved portion for accommodating the brushroll.
18 . The vacuum cleaner according to claim 1 , wherein the brushroll housing includes a top housing coupled to the bottom housing to at least partially surround the brushroll, wherein the outlet port is positioned along a rearward wall of the top housing.
19 . The vacuum cleaner according to claim 1 , wherein the bottom housing is integrally molded as a single piece including the front wall, rear wall, and the at least one rib.
20 . A vacuum cleaner comprising:
a suction motor operable to move working air through a working air flow path from a suction inlet to a clean air outlet;
a dirt separator located along the working air flow path to separate dirt from the working air; and
a surface cleaning head including
