I used a power bleeder I bought for my son but I did not put the fluid into the bleeder as is the normal practice. If you put the fluid in the bleeder, you do not have to worry about the level in the container above the master cylinder because it will just flow from the bleeder. But the disadvantage is you put fluid in the bleeder which is difficult to clean out and attracts moisture. I put it into the master cylinder container but have to refill between wheels. I just make sure it's full, pressurize, and then crack a bleed valve and let it run a bit (through a hose into an old soda bottle).

Two people works but you have to be coordinated. The person pumping the brakes cannot let up until the bleed valve is closed. If they do, you pull in air.
