4. A brush assembly according to claim 1, wherein the first agitator body comprises a main body portion having an outer tapered surface such that the diameter of the rotatably mounted end of the first agitator body is greater than the diameter of the free end.

5. A floor brush assembly for a surface cleaning apparatus according to claim 1, wherein the first agitating body comprises a body portion having an outer cylindrical surface such that the diameter of the rotatably mounted end of the first agitating body is equal or substantially equal to the diameter of the free end; the first stirring body is provided with a spirally extending bristle row in the direction from the mounting end to the free end, the bristle row extends outwards and radially to a first radial distance from the first stirring body, and the first radial distance is sequentially reduced in the direction from the mounting end to the free end.

6. A floor brush assembly for a surface cleaning apparatus according to claim 1, wherein the first agitating body comprises a body portion having an outer cylindrical surface such that the diameter of the rotatably mounted end of the first agitating body is equal or substantially equal to the diameter of the free end; a protrusion part extending spirally and a bristle row arranged on the protrusion part are arranged on the first stirring body in the direction from the mounting end to the free end, and the bristle row extends outwards and radially from the protrusion part; the projection extends radially outward from the first stirring body to a first radial distance that decreases in order in a direction from the mounting end to the free end.

7. The surface cleaning apparatus floor brush assembly of claim 6, wherein the protrusion includes a base and a pair of ridges, the base and the pair of ridges being arranged in series radially outward of the first agitator body, the row of bristles extending outward from the base, the row of bristles being disposed between the pair of ridges and the top end of the row of bristles extending from the pair of ridges.

8. A surface cleaning apparatus floor brush assembly according to claim 7, wherein the base has a second radial dimension and the rows of bristles have a constant third radial dimension, the second radial dimension decreasing in sequence in a direction from the mounting end to the free end such that the first radial distance decreases in sequence in a direction from the mounting end to the free end.

9. A surface cleaning apparatus floor brush assembly according to claim 7, wherein the base has a constant second radial dimension and the rows of bristles have a third radial dimension that decreases in sequence in a direction from the mounting end to the free end such that the first radial distance decreases in sequence in a direction from the mounting end to the free end.

10. A floor brush assembly according to claim 1, characterised in that the first agitator body and the second agitator body are driven by different motor assemblies.

11. A brush assembly according to claim 1, wherein the housing comprises a removable cover removably connected to the housing for at least partially covering the second agitator body but not the first agitator body.

12. A floor brush assembly for a surface cleaning apparatus according to claim 1 or 11, wherein the housing comprises a non-removable cover for at least partially covering the first agitating body but not the second agitating body.
