BACKGROUND

Extraction cleaners are well-known surface cleaning apparatuses for deep cleaning carpets and other fabric surfaces, such as upholstery. Most extraction cleaners, or deep cleaners, comprise a fluid delivery system that delivers cleaning fluid to a surface to be cleaned and a fluid recovery system that extracts spent cleaning fluid and debris (which may include dirt, dust, stains, soil, hair, and other debris) from the surface. The fluid delivery system typically includes one or more fluid supply containers for storing a supply of cleaning fluid, a fluid distributor for applying the cleaning fluid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning fluid from the fluid supply container to the fluid distributor. An agitator can be provided for agitating the cleaning fluid on the surface. The fluid recovery system usually comprises a recovery container, a nozzle adjacent the surface to be cleaned and in fluid communication with the recovery container through a working air conduit, and a source of suction in fluid communication with the working air conduit to draw the cleaning fluid from the surface to be cleaned and through the nozzle and the working air conduit to the recovery container.

Many extraction cleaners for household use are uprights, and include a base and an upright body having a handle for directing the base across the surface to be cleaned. Some extraction cleaners have been provided as autonomous robots, which carry the systems on an autonomously-moveable unit.

BRIEF SUMMARY

An aspect of the present disclosure relates to a cleaning tray for a surface cleaning apparatus having a base assembly with a suction nozzle and an agitator, including a body forming a tray having a recessed portion configured to at least partially surround at least one of the suction nozzle or the agitator, and an insert selectively received within at least a portion of the recessed portion and configured to engage the agitator.

Another aspect of the present disclosure relates to a self-cleaning method for an extraction cleaner having a fluid supply container and a fluid distributor, including docking an extraction cleaner in a cleaning tray having a recessed portion configured to sealingly receive a suction nozzle and an agitator of the extraction cleaner and having an insert configured to engage the agitator, rotating the agitator such that engagement with the insert scrapes debris from the agitator, distributing cleaning fluid from the fluid supply container into the recessed portion via the fluid distributor, and suctioning the cleaning fluid from the recessed portion into the extraction cleaner.

Yet another aspect of the present disclosure relates to a cleaning tray for a surface cleaning apparatus having a base assembly with a suction nozzle and an agitator, including a body forming a tray having a recessed portion configured to sealingly receive the suction nozzle and the agitator, the body having guide walls extending upwardly and configured to align the base assembly of the surface cleaning apparatus within the cleaning tray, and an insert selectively received within at least a portion of the recessed portion and configured to engage the agitator.
