Query: Stay with a new machine

I have a Roomba at my office, and I love it. I decided to try this remanufactured one to take home. The first time I turned it on it seemed to run fine, but then it started this intermittant shuttering, usually after bumping into things. My other Roomba never did this. I turned it off and packaged it back up and sent it back. I probably would have been fine keeping it, it did pick up like it should. It just sounded funny compared to my new Roomba. I am going to buy a brand new one now, remanufactured wasn't worth the savings I would have experienced. But I do love Roombas!
