Extractor tank assembly
A recovery tank for a surface cleaning apparatus such as an extractor is provided. The apparatus comprises a base positionable on the surface to be cleaned and includes a suction nozzle having a suction inlet in fluid communication with a duct and an exhaust outlet. The recovery tank is mountable to the base and has one or more walls and a bottom surface. The recovery tank includes a tank inlet extending through the bottom surface, wherein the tank inlet is positioned adjacent the base and operatively coupled to the duct outlet when the recovery tank is mounted to the base. A tank air outlet extends through the bottom surface, wherein the tank air outlet is positioned adjacent the base and operatively coupled to the exhaust outlet when the recovery tank is mounted to the base. A tank air outlet tube extends into the recovery tank from the tank air outlet.

5. The apparatus of claim 1 , the recovery tank further including a tank inlet tube extending into the recovery tank from the tank inlet.
6. The apparatus of claim 5 , wherein at least a portion of the tank inlet tube is spaced from the one or more walls to create a gap between the tank inlet tube and the one or more walls.
7. The apparatus of claim 6 , wherein the portion of the tank inlet tube is spaced from the one or more walls to allow fluid to flow around the portion of the tank inlet tube spaced from the one or more walls.
8. The apparatus of claim 6 , wherein the one or more walls comprise a front wall, wherein the tank inlet tube is spaced from the front wall.
9. The apparatus of claim 5 , wherein the tank inlet tube extends into the recovery tank in a rearward direction.
10. The apparatus of claim 1 , wherein the base includes a front portion and a rearward portion, and wherein the upper portion is operatively coupled to the rearward portion of the base.
11. An apparatus for cleaning a surface, the apparatus comprising:
a base positionable on the surface to be cleaned, the base including:
a suction nozzle having a suction inlet; and
a duct in fluid communication with the suction inlet and having a duct outlet; and
an exhaust outlet rearward of the duct outlet;
an upper portion operatively coupled to the base pivotable between an upright storage position and an operating position; and
a recovery tank removably mounted to the base, the recovery tank having one or more walls and a bottom surface, the recovery tank including:
a tank inlet extending through the bottom surface, wherein the tank inlet is positioned adjacent the base and operatively coupled to the duct outlet when the recovery tank is mounted to the base;
a tank air outlet extending through the bottom surface, wherein the tank air outlet is positioned adjacent the base and operatively coupled to the exhaust outlet when the recovery tank is mounted to the base; and
a tank air outlet tube extending into the recovery tank from the tank air outlet.
12. The apparatus of claim 11 , wherein at least a portion of the tank air outlet tube is spaced from the one or more walls to create a gap between the tank air outlet tube and the one or more walls.
13. The apparatus of claim 12 , wherein the portion of the tank air outlet tube is spaced from the one or more walls to allow fluid to flow around the portion of the tank air outlet tube spaced from the one or more walls.
14. The apparatus of claim 12 , wherein the one or more walls comprise a rear wall, wherein the tank air outlet tube is spaced from the rear wall.
15. The apparatus of claim 11 , the recovery tank further including a tank inlet tube extending into the recovery tank from the tank inlet.
16. The apparatus of claim 15 , wherein at least a portion of the tank inlet tube is spaced from the one or more walls to create a gap between the tank inlet tube and the one or more walls.
17. The apparatus of claim 16 , wherein the portion of the tank inlet tube is spaced from the one or more walls to allow fluid to flow around the portion of the tank inlet tube spaced from the one or more walls.
18. The apparatus of claim 16 , wherein the one or more walls comprise a front wall, wherein the tank inlet tube is spaced from the front wall.
19. The apparatus of claim 15 , wherein the tank inlet tube extends into the recovery tank in a rearward direction.
