They can work. They're better than swivel casters. That just isn't saying much, though.
Honestly, skid pads would work quite well to replace casters, if it weren't for the bumps in the floor. (Though that could be dealt with--see if you can get a look at 1266's rookie robot.)
FYI, I don't know of a single problem with 330's omnis last year, and they took a heavy pounding. AM plastics, I want to say 8", dual configuration.
The trick with omni wheels is to put two wheels per wheel, placed so that the rollers on one wheel fill in the between-roller gaps on the other wheel (the dual configuration I mentioned above). It provides a smoother ride, reducing wear and tear on the wheel overall.
