Extraction cleaner with cleaning and debris separation
The present disclosure provides a cleaning device comprising a body, a suction source, and a suction head operably coupled to the body and defining at least one suction opening in fluid communication with the suction source. The suction opening intakes debris from a surface to be cleaned. The suction head comprises a wall, an agitator configured to agitate the surface, and a fluid dispenser configured to dispense fluid onto a portion of the wall prior to making contact with the surface.
1 . A cleaning device, comprising:
a body;
a suction source; and
a suction head operably coupled to the body and defining at least one suction opening in fluid communication with the suction source, the at least one suction opening being configured to intake debris from a surface to be cleaned, the suction head comprising:
a wall,
an agitator configured to agitate the surface to be cleaned, and
a fluid dispenser configured to dispense fluid within the suction head onto a portion of the wall prior to making contact with the surface to be cleaned, wherein a maximum width of the portion of the wall is greater than a maximum width of the agitator.
2 . The cleaning device of claim 1 , wherein the suction head further comprises a first suction inlet and a second suction inlet, both fluidly coupled to the suction source.
3 . The cleaning device of claim 2 , wherein the first suction inlet is disposed forward of the agitator and the second suction inlet is disposed rearward of the agitator.
4 . The cleaning device of claim 1 , wherein an angle between the portion of the wall and the surface to be cleaned is between about 0 to about 30 degrees.
5 . The cleaning device of claim 1 , wherein the fluid dispenser is disposed above the portion of the wall.
6 . The cleaning device of claim 1 , wherein the fluid dispenser is a first fluid dispenser and the suction head further comprises a second fluid dispenser, and wherein a width between the first fluid dispenser and the second fluid dispenser is less than the maximum width of the agitator.
7 . The cleaning device of claim 1 , wherein the fluid dispenser comprises a manifold cover and a plurality of spray nozzles integrated within the manifold cover.
8 . The cleaning device of claim 7 , wherein the manifold cover is configured to block at least a portion of the debris from reaching the plurality of spray nozzles.
9 . A cleaning device, comprising:
an upright body; and
a cleaning head operably coupled to the upright body, the cleaning head being configured to move across a surface to be cleaned and comprising:
at least one suction nozzle configured to draw in debris from the surface to be cleaned,
an agitator disposed adjacent to the at least one suction nozzle, the agitator being configured to agitate the surface to be cleaned, and
a fluid dispenser disposed at a first wall of the cleaning head and configured to dispense fluid onto a second wall of the cleaning head such that the dispensed fluid spreads over a width of the second wall prior to contacting the surface to be cleaned, the fluid dispenser comprising a manifold cover having a plurality of spray nozzles integrated therein, the spray nozzles being configured to dispense fluid onto the second wall.
10 . The cleaning device of claim 9 , wherein the second wall is curved and positioned vertically above the agitator such that the dispensed fluid flows downward via gravity from the first wall onto the second wall and onto the surface to be cleaned.
11 . The cleaning device of claim 10 , wherein the second wall extends longitudinally along a length of the agitator and includes one or more deflectors positioned beneath the fluid dispenser to promote lateral dispersion of the dispensed fluid.
12 . The cleaning device of claim 9 , wherein the spray nozzles are spaced apart to distribute fluid across the width of the second wall.
13 . The cleaning device of claim 9 , wherein a maximum width of the second wall is greater than a maximum width of the agitator.
14 . The cleaning device of claim 13 , wherein the fluid dispenser is a first fluid dispenser and the cleaning head further comprises a second fluid dispenser, and wherein a width between the first fluid dispenser and the second fluid dispenser is less than the maximum width of the agitator.
15 . The cleaning device of claim 9 , wherein the at least one suction nozzle comprises a first suction inlet disposed forward of the agitator and a second suction inlet disposed rearward of the agitator.
16 . The cleaning device of claim 15 , further comprising a diverter valve fluidly coupled to the first suction inlet and the second suction inlet, the diverter valve being selectively configurable to direct suction flow between the first suction inlet and the second suction inlet.
17 . The cleaning device of claim 9 , wherein the fluid dispenser is fluidly coupled to at least one standpipe configured to vent air.
