Abstract
A surface cleaning apparatus is provided with a base assembly, an upright assembly, and a fluid recovery system. The base assembly includes a base housing, a brush chamber, at least one brushroll in the brush chamber; and a removable brush housing. A portion of the brush chamber is removable with the brush housing.
Claims20
An accessory tool for use with a cleaning apparatus, the accessory tool comprising:
- a tool body including a forward portion defining a first plane and a second plane, wherein the first plane converges with the second plane at an intersection;
- a wet suction nozzle having a wet suction nozzle inlet disposed at the first plane;
- a dry suction nozzle having a dry suction nozzle inlet disposed at the second plane, wherein the wet suction nozzle inlet is fluidly isolated from the dry suction nozzle inlet such that only one of the wet suction nozzle inlet and the dry suction nozzle inlet can be moved into contact with a surface to be cleaned at a time, and wherein a first agitation feature is disposed between the wet suction nozzle and the intersection and a second agitation feature is disposed between the dry suction nozzle and the intersection, wherein the tool body is free of nozzle inlets disposed between the first agitation feature and the second agitation feature;
- a diverter fluidly connected to the wet suction nozzle and the dry suction nozzle, separately, to selectively adjust said accessory tool between a wet cleaning mode and a dry cleaning mode;
- a removable collection chamber supported at the tool body, the removable collection chamber being in fluid communication with the dry suction nozzle and configured to recover dirt and debris recovered by the dry suction nozzle;
- and
- a hose connector disposed on the tool body, the hose connector including a working air conduit opening and a fluid opening.

An accessory tool for use with a cleaning apparatus, the accessory tool comprising:
- a tool body including:
- a forward portion defining a first plane and a second plane;
- and
- a rear portion including an actuator;
- a wet suction nozzle disposed at the first plane spaced from and positioned forward of a first agitation feature;
- a dry suction nozzle disposed at the second plane spaced from and positioned rearward of a second agitation feature, wherein the wet suction nozzle is fluidly isolated from the dry suction nozzle, and wherein the first plane converges with the second plane at an intersection disposed between the wet suction nozzle and the dry suction nozzle, and further wherein the tool body can be pivoted forward about the intersection to move the wet suction nozzle into contact with a surface to be cleaned and also pivoted rearward about the intersection to move the dry suction nozzle into contact with the surface to be cleaned, wherein the tool body does not draw suction between the first agitation feature and the second agitation feature;
- and
- a fluid distributor disposed between the wet suction nozzle and the dry suction nozzle, the fluid distributor including a spray nozzle positioned within a fluid distributor chamber that is open to the surface to be cleaned and which includes a fluid outlet adjacent a wet suction nozzle inlet through which fluid can be dispensed onto the surface to be cleaned.
5 more elements
An accessory tool actuatable between a wet cleaning mode and a dry cleaning mode, the accessory tool comprising:
- a tool body;
- an actuator operably connected with the tool body and movable between a first position that adjusts the tool body to said wet cleaning mode and a second position that adjusts the tool body to said dry cleaning mode;
- a wet suction nozzle disposed on a forward portion of the tool body;
- bristles disposed adjacent the wet suction nozzle;
- a dry suction nozzle separate and distinct from the wet suction nozzle, wherein the dry suction nozzle is disposed between the wet suction nozzle and the actuator, and wherein the wet suction nozzle is fluidly isolated from the dry suction nozzle;
- a diverter fluidly connected to the wet suction nozzle and the dry suction nozzle, separately, to selectively adjust said accessory tool between said wet cleaning mode and said dry cleaning mode;
- nubs disposed adjacent the dry suction nozzle, wherein there are no suction nozzles disposed between the bristles and the nubs;
- and
- a collection chamber removably supported at the tool body, the collection chamber only in fluid communication with the dry suction nozzle.
