The spot treating device includes features that allow a user to conveniently spot treat laundry articles and provides for an improved visual rendering of the laundry articles during a treatment operation. ## Claims ### Claim 1 A washing machine appliance defining a vertical, a lateral, and a transverse direction, the washing machine appliance comprising: a cabinet including a top panel, the top panel defining an opening; a tub positioned within the cabinet; a wash basket rotatably mounted within the tub, the wash basket defining a wash chamber for receiving articles for washing; and a spot treating assembly for treating articles, the spot treating assembly comprising: a hose fluidly connected with a water supply; and a spot treating device, comprising: a housing defining a main opening extending therethrough and one or more spray openings fluidly connected with the hose for dispensing a wash fluid; and a magnifying device disposed within the main opening of the housing for magnifying articles. ### Claim 2 (depends on 1) The washing machine appliance of claim 1, wherein the housing extends between a top and a bottom along the vertical direction, and wherein the magnifying device comprises a first lens disposed within the main opening at or proximate the top and a second lens disposed within the main opening at or proximate the bottom of the housing. ### Claim 3 (depends on 2) The washing machine appliance of claim 2, wherein a vantage point is defined above the top of the housing along the vertical direction, and wherein the first lens has a convex shape with respect to the vantage point and the second lens has a concave shape with respect to the vantage point. ### Claim 4 (depends on 1) The washing machine appliance of claim 1, wherein the one or more spray openings comprise at least one spray opening extending between an inlet and an outlet, and wherein the at least one spray opening tapers between the inlet and the outlet. ### Claim 5 (depends on 1) The washing machine appliance of claim 1, wherein the housing extends between a top and a bottom along the vertical direction, and wherein a vantage point is defined above the top of the housing along the vertical direction, and wherein the magnifying device comprises a lens having a top surface and an opposing bottom surface, the lens disposed within the main opening such that the top surface of the lens is positioned at or proximate the top of the housing and the bottom surface is positioned at or proximate the bottom of the housing, and wherein the top surface has a convex shape with respect to the vantage point and the bottom surface has a concave shape with respect to the vantage point. ### Claim 6 (depends on 1) The washing machine appliance of claim 1, wherein the spot treating device further comprises a brush attached to the housing. ### Claim 7 (depends on 1) The washing machine appliance of claim 1, wherein the spot treating device further comprises an illumination device attached to the housing. ### Claim 8 (depends on 1) The washing machine appliance of claim 1, wherein the spot treating device further comprises a scraper, wherein the scraper is retractable within a recess defined by the housing of the spot treating device. ### Claim 9 (depends on 1) The washing machine appliance of claim 1, wherein the housing defines a fluid delivery channel fluidly connecting the one or more spray openings with the hose and with one another, and wherein the fluid delivery channel extends annularly about the main opening. ### Claim 10 (depends on 9) The washing machine appliance of claim 9, wherein the fluid delivery channel comprises an inlet, and wherein the spot treating device further comprises an inlet valve positioned at the inlet for selectively allowing a flow of wash fluid into the spot treating device. ### Claim 11 (depends on 10) The washing machine appliance of claim 10, wherein the spot treating device further comprises: an actuation mechanism for actuating the inlet valve between an open position and a closed position; and an activation mechanism for triggering the actuation mechanism. ### Claim 12 (depends on 1) The washing machine appliance of claim 1, wherein the housing defines a fluid delivery channel fluidly connecting the one or more spray openings with the hose, the fluid delivery channel comprising a first channel and a second channel, and wherein the one or more spray openings comprise at least one tapered spray opening along the first channel and the one or more spray openings comprise at least one non-tapered opening along the second channel, the fluid delivery channel having an inlet, the spot treating device further comprising: an inlet valve positioned at the inlet of the fluid delivery channel for selectively allowing a flow of wash fluid into the first channel and selectively allowing a flow of wash fluid into the second channel. ### Claim 13 (depends on 1) The washing machine appliance of claim 1, wherein the hose is a spiral hose moveable between an extended positon and a retracted position. ### Claim 14 A washing machine appliance defining a vertical, a lateral, and a transverse direction, the washing machine appliance comprising: a cabinet including a top panel, the top panel defining an opening; a tub positioned within the cabinet; a wash basket rotatably mounted within the tub, the wash basket defining a wash chamber for receiving articles for washing; and a spot treating device for treating articles, comprising: a housing; a fluid delivery conduit fluidly connecting the spot treatment device with a fluid supply; and a magnifying device attached to at least one of the fluid delivery conduit and the housing for magnifying articles. ### Claim 15 (depends on 14) The washing machine appliance of claim 14, wherein the housing comprises a main body, a top member extending outward from the main body, and a bottom member extending outward from the main body and spaced from the top member, the main body, the top member, and the bottom member defining a cavity, and wherein the spot treating device comprises: an ultrasonic plate for conveying ultrasonic vibrations to articles, the ultrasonic plate attached to the top member and disposed within the cavity, the ultrasonic plate and top member defining a plurality of spray openings for dispensing a wash fluid onto articles; and a suction plate for collecting wash fluid dispensed from spray openings, the suction plate attached to the bottom member and disposed within the cavity. ### Claim 16 (depends on 14) The washing machine appliance of claim 14, further comprising: a top panel, the top panel defining a cavity sized to receive the spot treating device. ### Claim 17 (depends on 14) The washing machine appliance of claim 14, wherein the magnifying device is attached to the fluid delivery conduit by a linked shaft comprised of a series of frictionally attached links. ### Claim 18 (depends on 14) The washing machine appliance of claim 14, wherein the magnifying device comprises a frame and a shaft extending from the frame, wherein the washing machine appliance further comprises: a clamp sized to receive the fluid delivery conduit and comprising a clamp shaft extending therefrom; and an extension shaft extending between a proximal end and a distal end, the proximal end coupled with the clamp shaft via a ball socket joint, and wherein the distal end of the extension shaft is coupled with the shaft of the magnifying device via a ball socket joint.
