Our previous coach had the electric flush and I had to replace the fuse about 4 times plus I had to clean the slot for the blade due to paper getting caught in it.
Our current coach has a pedal flush with a ball instead of the blade and we love it. Ours is a Sealand with the ceramic bowl. I do have to clean the ball with a brush but this one is much more convenient to use and there is no dependence on 12V. I keep a one gallon jug of water next to it (we had a problem with a control board and lost all 12V to the coach).
