Surface cleaning apparatus
A surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the liquid collection container and the solid collection chamber are emptyable concurrently.
1. A surface cleaning apparatus comprising:
a) a surface cleaning head having a front end having a dirty fluid inlet; and,
b) an upright section moveably mounted to the surface cleaning head, the upright section moveable between an upright storage position in which the upright section is supported by the surface cleaning head and a reclined surface cleaning position, the upright section comprising:
i) a first stage non-cyclonic liquid separator having a liquid collection container, a liquid separator fluid inlet downstream from the dirty fluid inlet and a liquid separator fluid outlet;
ii) a second stage cyclone separator comprising a cyclone chamber and a solid collection chamber exterior to the cyclone chamber, the cyclone chamber having a cyclone chamber fluid inlet, a cyclone chamber dirt outlet in communication with the solid collection chamber and a cyclone chamber fluid outlet, wherein fluid exiting the liquid separator fluid outlet passes to the cyclone chamber fluid inlet without passing through the solid collection chamber; and,
iii) a suction motor downstream from the second stage cyclone separator,
wherein the liquid collection container and the solid collection chamber are emptyable concurrently.
2. The surface cleaning apparatus of claim 1 , wherein, when the upright section is in the storage position, the solid collection chamber is positioned at a same elevation as the liquid collection container.
3. The surface cleaning apparatus of claim 1 , wherein the solid collection chamber is positioned laterally beside the liquid collection container.
4. The surface cleaning apparatus of claim 1 , wherein, the solid collection chamber and the liquid collection container are removable concurrently from the upright section.
5. The surface cleaning apparatus of claim 4 , wherein the solid collection chamber and the liquid collection container are removable from the upright section in a closed configuration.
6. The surface cleaning apparatus of claim 4 , wherein the first stage non-cyclonic liquid separator and the second stage cyclone separator are removable concurrently from the upright section.
7. The surface cleaning apparatus of claim 4 , wherein the solid collection chamber and the liquid collection container are of a unitary construction.
8. The surface cleaning apparatus of claim 7 , wherein the solid collection chamber and the liquid collection container are integrally formed.
9. The surface cleaning apparatus of claim 4 , wherein the first stage non-cyclonic liquid separator and the second stage cyclone separator are removable in a sealed configuration other than the liquid separator fluid inlet and the cyclone chamber fluid outlet.
10. The surface cleaning apparatus of claim 1 , wherein the solid collection chamber and the liquid collection container have an openable top.
11. The surface cleaning apparatus of claim 10 , wherein the openable top comprises the cyclone chamber.
12. The surface cleaning apparatus of claim 11 , wherein the solid collection chamber is positioned laterally beside the liquid collection container and the cyclone chamber has a cyclone axis of rotation that intersects the liquid collection container.
13. The surface cleaning apparatus of claim 11 , wherein the solid collection chamber is positioned laterally beside the liquid collection container and the cyclone chamber overlies the liquid collection container.
14. A surface cleaning apparatus comprising:
a) a first stage non-cyclonic liquid separator having a liquid collection container, a liquid separator fluid inlet downstream from the dirty fluid inlet and a liquid separator fluid outlet;
b) a second stage cyclone separator comprising a cyclone chamber and a solid collection chamber exterior to the cyclone chamber, the cyclone chamber having a cyclone chamber fluid inlet, a cyclone chamber dirt outlet in communication with the solid collection chamber and a cyclone chamber fluid outlet, wherein fluid exiting the liquid separator fluid outlet passes to the cyclone chamber fluid inlet without gassing through the solid collection chamber; and,
c) a suction motor downstream from the second stage cyclone separator,
wherein the liquid collection container and the solid collection chamber are emptyable concurrently.
15. The surface cleaning apparatus of claim 14 , wherein the solid collection chamber is positioned laterally beside the liquid collection container.
16. The surface cleaning apparatus of claim 14 , wherein, the solid collection chamber and the liquid collection container are removable concurrently from the surface cleaning apparatus.
17. The surface cleaning apparatus of claim 16 , wherein the solid collection chamber and the liquid collection container are removable from the surface cleaning apparatus in a closed configuration.
18. The surface cleaning apparatus of claim 14 , wherein the first stage non-cyclonic liquid separator and the second stage cyclone separator are removable concurrently from the surface cleaning apparatus.
19. The surface cleaning apparatus of claim 18 , wherein the first stage non-cyclonic liquid separator and the second stage cyclone separator are removable in a sealed configuration other than the liquid separator fluid inlet and the cyclone chamber fluid outlet.
20. The surface cleaning apparatus of claim 14 , wherein the solid collection chamber and the liquid collection container have an openable top and the openable top comprises the cyclone chamber.
