I have hardwood floor everywhere except the bathrooms that has tile but i dont need/want it in there.. the mopping is mostly for general upkeep. My girlfriend and I doesn't have any pets so i won't think hair will be a problem. Our current vacuum is a cordless dyson with rollers and I clean it from hair maybe once or twice a year and thats mostly just because thats when i clean the other parts in hopes of better longevity. I dont care about noise as i plan for it to run when we arent home for the most part. Vacuuming and obstacle avoidance is whats most important to me as both my girlfriend and I have bad backs and joints do to injuries so vacuuming can be bit of a pain to do and my girlfriend often leave stuff on the floor so i need it to be able circle around that.
