Abstract
A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.
Claims19
A surface cleaning apparatus comprising:
- a) a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid,
- b) an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a cyclone axis of rotation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit, the liquid blocking collar is provided on the treated air outlet conduit at an elevation below an inlet to the treated air outlet conduit and above the cyclone fluid inlet;
- and,
- c) a solid and liquid collection chamber in communication with the separated element outlet,
- wherein the inverted cyclone has a cyclone sidewall and the separated element outlet is provided in the sidewall of the inverted cyclone, and
- wherein the cyclone fluid inlet has a width in a plane transverse to the cyclone axis of rotation and the liquid blocking collar is located radially inwardly from the cyclone sidewall by a distance that is at least equal to the width.
A surface cleaning apparatus comprising:
- a) a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid,
- b) an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a first end, a first end wall, a second end, a second end wall, a cyclone axis of rotation and a sidewall extending between the first and second ends, the first end having a cyclone fluid inlet and a cyclone air outlet and the second end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated air outlet conduit;
- and,
- c) a solid and liquid collection chamber in communication with the separated element outlet,
- wherein the cyclone fluid inlet has a width in a plane transverse to the cyclone axis of rotation and the liquid blocking collar is located radially inwardly from the cyclone sidewall by a distance that is at least equal to the width.
