Dave,
Most of them come with caster kits that allow them to be moved easily just so long as you have the wheels going in the right direction. The wheels are wide steel ones that don't pivot easily but once rolling in the desired direction, one person can do it with little effort.
Also, most just use the wheels to move the lift to try different positions in their garage and don't make a daily thing of it. Once placed where you want it, the wheel kits are removed and the lift stays put. A decent four post lift doesn't need to be anchored to the floor either. The wheel kits tend to get in the way if you leave them on and they are a storage problem if you take them off but they are great when you really need them. Note that your electric power to the lift must be removed first unless you are only moving it a few feet or so.
