You actually can't tilt a Genesis like you can a
Brinsea. The
brinsea tilts to 45 degrees. That's the idea turning angle according to hatchability research. Anything less than that hurts hatches. You'd have to stand the Genesis up on two or three phone books to get that angle, and all your eggs would fall over.
To clean the top section (above the plastic grate) you take six screws out and just wash it with soapy water. Instructions are in the manual. I don't do it for every hatch but maybe every other. It takes ninety seconds tops.
Maybe I'm just lucky, but I've run them in conditions ranging from 70 percent humidity (early fall) to 20 percent humidity (right now, with the ground frozen and the pellet stove going 24/7) and I never have any trouble getting a rock-solid RH. When it's wetter outside, one well equals 37-40% humidity and two gets you 60+ for lockdown. When it's dry, two wells equals 37% and two sponges or maxipads equals 65%. I've been looking at a hygrometer that says 65% for the last two days, never varies. When I saw it drop to 62 when I got up this morning I added more water (wells were empty) and in less than a minute it was at 65 again.
The biggest thing for me, for sure, is NO DUMB LOCKDOWN in the
Brinsea. You can open it as often as four times a day according to the manual and in my experience you can do it even more often if you add hot water each time you open it. No soul-searching about taking out hungry or thirsty chicks, no freaking out because the incubator is out of water and the RH is dropping, no sitting and watching and being unable to intervene.
