I don't have much in the way of upper body strength, so take this FWIW...I can barely roll my PG500 around on a concrete patio.
Regarding going through the house...The wheels are hard plastic. I'm sure that they'll scratch a wood floor. I'd get a moving blanket, get the unit on it and drag the blanket across any hardwood floor areas. Or put down cardboard or something to protect the hardwood.
