What is the best vacuum for hardwood floors, throw rugs, upholstry, and pets?

I am looking for a vacuum that won't scratch my hardwood floors, easily switches to brush roll for throw rugs, has onboard attachments for upholstry, and works great for picking up pet hair. Also, would prefer that it isn't too heavy or loud, has good suction and doesn't clog, has reasonable power cord & upholstry hose length. I know this is a lot to ask but there's got to be one out there. Any suggestions?
