Clean up
I line the "tree tray" with foil (see picture above) so that item doesn't even need to be washed. I wipe the interior down with a sudsy sponge and that's usually enough to remove spatters, then go over it again with the sponge just dampened with plain water. The tricky area is the open nichrome wire heating coils. You can't really do much up there.
The front glass is removable, and that gets hand washed. I've run it through various dishwashers we've owned, but none have been able to get the grease spatters entirely removed.
The spit isn't a big deal to wash by hand. I put the skewers in the dishwasher if I'm going to run it that same night.
The recipe book says to use a 3.5 - 4 pound bird. I always buy a minimum 5-pound bird. They shrink when they cook, and there's no sign of stress on the motor or mechanism. It even handled one that was pushing six pounds, but I try to stay within the 5 to 5.5 pound range.
The gears are a little sloppy, so getting the bird properly trussed and well-balanced on the spit is the key to evenly cooked skin, otherwise you'll get some less done areas where rotation falls forward, and blackened areas where rotation falls behind and the spit momentarily stops as the gears catch up. Balancing the bird on the spit can often take several tries. I twirl the spit by hand to get a feel for which side is heavier than the other, and reposition skewers accordingly. It's trial and error but worth spending the time. Perfect balance isn't likely, but as the bird cooks it becomes lighter, and the rotation becomes smoother.
For me, the finished product is well worth the trouble. I'm not a fan of white meat. It's usually way too dry. That's not the case when it's done in the Roto-Broil. The breast is tender and juicy, the way it's supposed to be, and I'm fine with letting Dave have the dark meat.
