I rarely move mine, but when I do the wheels are a must (obviously) unless you want to unload the whole thing. I also like having it on wheels so I can blow out the area under it. Having everything off the ground helps with shop clean up for sure. I used 3” wheels which were a mistake. I use 4” poly on everything else and it all moves fine, these cheaper 3” hard plastic wheels suck. I put them on because they were cheap and I f if it’s I wasn’t going to move it much.  Buy once, cry once.
