The suction nozzle is configured to extract recovered liquid and dirt. The cleaning tool also includes an internal conduit in fluid communication with the suction nozzle configured to transport recovered liquid and dirt extracted by the suction nozzle. The internal conduit extending longitudinally within the handle portion between opposite ends of the handle portion. The cleaning tool further includes a spray nozzle configured to distribute cleaning liquid forward of the nozzle cover and a supply tube configured to carry cleaning liquid to the spray nozzle. The spray nozzle passes through the suction nozzle or the inlet conduit. ## Claims ### Claim 1 A cleaning tool for an extraction cleaner comprising: a tool body including a nozzle portion connected to an elongated handle portion; a nozzle cover removably mounted to the nozzle portion; a suction nozzle configured to extract recovered liquid and dirt, the suction nozzle formed between the nozzle portion and the nozzle cover; an internal conduit configured to transport recovered liquid and dirt extracted by the suction nozzle, the internal conduit extending longitudinally within the handle portion between opposite ends of the handle portion and having an inlet in fluid communication with the suction nozzle and an outlet configured to connect to an external hose; a spray nozzle configured to distribute cleaning liquid forward of the nozzle cover, the spray nozzle mounted to the nozzle portion; a valve mechanism configured to control a flow of cleaning liquid to the spray nozzle, the valve mechanism mounted to the handle portion peripherally of the internal conduit and in fluid communication with the spray nozzle; and a supply tube configured to carry cleaning liquid to the valve mechanism, the supply tube connected in fluid communication with the valve mechanism and extending at least partially within the internal conduit. ### Claim 2 (depends on 1) The cleaning tool of claim 1, wherein the spray nozzle passes through the suction nozzle or the inlet conduit. ### Claim 3 (depends on 2) The cleaning tool of claim 2, wherein the nozzle portion includes a frontal wall connected to a forward section of the handle portion adjacent a forward end of the internal conduit, the nozzle cover forming a fluid connection between the suction nozzle and the internal conduit, the nozzle cover having an aperture aligned with the spray nozzle configured for the spray nozzle to distribute cleaning liquid through the nozzle cover. ### Claim 4 (depends on 1) The cleaning tool of claim 1, wherein at least a portion of the spray nozzle is connected to and removable with the nozzle cover. ### Claim 5 (depends on 1) The cleaning tool of claim 1, wherein the spray nozzle includes a spray tip, and the spray tip is connected to and removable with the nozzle cover. ### Claim 6 (depends on 1) The cleaning tool of claim 1, wherein the handle portion includes a top wall along a length of the handle portion and a bottom wall connected to the top wall and including a forward section having a recess and a rear section, and the recess of the forward section transitions to the rear section at a step transition area of the bottom wall. ### Claim 7 (depends on 6) The cleaning tool of claim 6, wherein the supply tube extends through an opening formed in the step transition area. ### Claim 8 (depends on 6) The cleaning tool of claim 6 further comprising: a tool body cover attached to the bottom wall over the forward section covering a first portion of the valve mechanism and receiving an actuator in an opening formed through the tool body cover configured to actuate the valve. ### Claim 9 (depends on 1) The cleaning tool of claim 1, wherein the supply tube is configured to connect to a delivery tube carried within the external hose and configured to deliver cleaning liquid from the extraction cleaner. ### Claim 10 (depends on 1) The cleaning tool of claim 1, wherein the supply tube extends through the external hose and configured to deliver cleaning liquid from the extraction cleaner. ### Claim 11 (depends on 10) The cleaning tool of claim 10 further comprising: a cleaning head removably mounted to the nozzle portion, wherein the nozzle cover is removably mounted above a frontal wall of the nozzle portion and the cleaning head is removably mounted below the frontal wall of the nozzle portion, and the cleaning head includes a catch configured to engage resiliently with the nozzle portion. ### Claim 12 (depends on 11) The cleaning tool of claim 11, wherein the cleaning head is disposed in a plane that is at an acute angle with respect to a longitudinal axis of the handle portion. ### Claim 13 (depends on 1) The cleaning tool of claim 1 further comprising: the handle portion having a detent formed by an aperture through a wall of the internal conduit, and the nozzle cover having a button on a resilient member configured to releasably engage the detent through the internal conduit inlet, wherein the button inhibits air ingress through the aperture into the internal conduit. ### Claim 14 (depends on 13) The cleaning tool of claim 13, wherein the button includes a seal engagable with the aperture. ### Claim 15 (depends on 1) The cleaning tool of claim 1 further comprising: a cleaning head removably mounted to the nozzle portion, wherein the nozzle cover is removably mounted above a frontal wall of the nozzle portion and the cleaning head is removably mounted below the frontal wall of the nozzle portion, and the cleaning head includes a catch configured to engage resiliently with the nozzle portion. ### Claim 16 (depends on 15) The cleaning tool of claim 15, wherein the cleaning head is disposed in a plane that is at an acute angle with respect to a longitudinal axis of the handle portion. ### Claim 17 A cleaning tool for an extraction cleaner comprising: a tool body including a nozzle portion connected to an elongated handle portion; a nozzle cover removably mounted to the nozzle portion forming a suction nozzle therebetween, the suction nozzle configured to extract recovered liquid and dirt; an internal conduit in fluid communication with the suction nozzle configured to transport recovered liquid and dirt extracted by the suction nozzle, the internal conduit extending longitudinally within the handle portion between opposite ends of the handle portion, a spray nozzle configured to distribute cleaning liquid forward of the nozzle cover, and a supply tube configured to carry cleaning liquid to the spray nozzle, wherein the spray nozzle passes through the suction nozzle or the inlet conduit. ### Claim 18 (depends on 17) The cleaning tool of claim 17 further comprising: a valve mechanism configured to control a flow of cleaning liquid to the spray nozzle, the valve mechanism mounted to the handle portion peripherally of the internal conduit between the supply tube and the spray nozzle. ### Claim 19 (depends on 18) The cleaning tool of claim 18, wherein the supply tube includes a first portion extending within the internal conduit and a second portion peripherally of the internal conduit, and the valve mechanism is between the second portion of the supply tube and the spray nozzle. ### Claim 20 (depends on 19) The cleaning tool of claim 19, wherein the internal conduit of the handle portion is connected to an external hose, and the first portion of the supply tube extends through the external hose configured to deliver cleaning liquid from the extraction cleaner. ### Claim 21 (depends on 17) The cleaning tool of claim 17, wherein the nozzle portion includes a frontal wall connected to the forward section of the handle portion adjacent a forward end of the internal conduit, the nozzle cover forming a fluid connection between the suction nozzle and the internal conduit, the nozzle cover having an aperture aligned with the spray nozzle configured for the spray nozzle to distribute cleaning liquid through the nozzle cover. ### Claim 22 (depends on 21) The cleaning tool of claim 21 wherein at least a portion of the spray nozzle is connected to and removable with the nozzle cover. ### Claim 23 (depends on 17) The cleaning tool of claim 17, wherein the valve mechanism is actuatable by a trigger.
