1. A portable spray device for spraying pretreatment liquid to an area of a fabric shirt, the portable spray device comprising:
a housing portion having a leading end, a trailing end, a first lateral side, and a second lateral side,
a first wheel positioned at the first lateral side of the housing portion, and having a first axis of rotation,
a second wheel positioned at the second lateral side of the housing portion, and having a second axis of rotation,
at least a third wheel positioned at the leading end of the housing portion, and having a third axis of rotation,
at least one motor attached to the housing portion for rotating the first wheel and the second wheel,
a sprayer attached to the housing portion at the trailing end thereof, and being configured to spray the pretreatment liquid therefrom, and
a controller configured to activate the at least one motor to rotate the first wheel and the second wheel, and configured to activate the sprayer to spray the pretreatment liquid therefrom,
wherein, when the first wheel, the second wheel, and the third wheel are positioned on a portion of the fabric shirt, the controller is configured to activate rotation of the first wheel and the second wheel to move the portable spray device from a first position on the fabric shirt to a second position on the fabric shirt, and to simultaneously operate the sprayer to spray the pretreatment liquid in a spray area on the fabric shirt during movement of the portable spray device from the first position to the second position, and
when the first wheel, the second wheel, and the third wheel are contacted to the fabric shirt, a first plane perpendicular to the first axis of rotation passes through the first wheel and the spray area, a second plane perpendicular to the second axis of rotation passes through the second wheel and the spray area, and a third plane perpendicular to the third axis of rotation passes through the third wheel, through the spray area, and is positioned between the first plane and the second plane.
