What is the best vacuum for overall duties?

I pose this question to mothers because you know how important a vacuum can be when you have toddlers and children. I'm trying to find the best vacuum... and I don't care about cost. My house has marble & granite floors, ceramic tile, and wood floors... with area rugs throughout. I've been forever looking for the best vacuum for all my needs. One that has good suction, has easy onboard tools that actually meet all needs, has a long enough hose that when being used, doesn't tip the vacuum over. I don't care if it's with bag or bagless.
