Cleaning either the Wagner Heads or the Graco** Heads is as simple as unscrewing the external Collar Ring, pulling off the Nozzle Guard, and up ending the Head and rinsing a stream of water through it. Yeah, ya gotta rinse out the Paint Cup too, after your all done painting. (**...btw, the Graco's Needle / Nozzle assembly is Brass, and that makes rinsing off even easier...)
If the paint use is diluted to the point it should be, and it's water based, it is not necessary to rinse the Gun out after every coating if the times between each coating is 30 minutes or under. Also, if the care is taken to take a damp cloth and wipe the nozzle off, things get even better. Otherwise, just a small amount of collected build-up on the Nozzle assembly can result in a reduced sized spray pattern.
But 2 hours? No...because by that time the Latex has a chance to congeal onto surfaces...even those inside the Gun, and although they can be cleaned, cleaning then digresses from mere rinsing to scrubbing using a little Pipe Brush. . A quick rinsing of the Head and Feeder Tube is just that...3 minutes at most.
Now if you plan to use Oil Based paint, get the $50.00 Refurb Graco 2900. It has become the Del Facto standard these days, and it's metal components are ideally suited for Oil Paints, Stains, and Varnishes. The Plastic components in the Wagners WILL demand they be cleaned out ASAP because of the drying agents in such oil derived materials.
