Bests & Worsts Reviews from Amazon

EDITED: I HAVE SINCE HAD SEVERAL ISSUES WITH THIS UNIT. NOT ONLY DOES IT NOT WORK LIKE ADVERTISED I GET ERROR MESSAGE AFTER ERROR MESSAGE. AMAZON WONT HELP, EVEN THO I AM A PRIME MEMBER AND SPEND THOUSANDS WITH THEM, IROBOT HAS TROUBLE SHOOTED FOR HOURS AND NOW SEND A REPLACEMENT AND FROM THE BOX IT WONT WORK. ALL I WANT IS MY MONEY BACK. SAVE YOURSELF THE ISSUES DONT BUY THIS IT IS A PEICE OF JUNK. YOU WONT GET HELP THEY JUST WANT YOUR MONEY. I wanted to love this but for 450.00 it doesnt somewhat it should. I have laminate medium colored wood and it leaves tire Mark's and a horrible haze on my floor and I've tried all different ways to clean and even bought the reusable pads. I dont understand how an item that costs this much would not clean like it should. Maybe mine is defective. I may have to contact Amazon. I'm sad!
