Very disapointed customer. Good idea for a product but only why it lasts. Several months ago I spent a bunch of money on your product because it was the best there was according to reviews. I bought a factory refurbished unit as I could not afford the 500+ for a new one. It was promised to come with warranty. After two weeks the robot would just die. I called support and they sent replacement batteries. Those lasted a day. After many failed attempts of getting support, and waiting for an "email" to return it for repair (more money I would have to spend, not only for the shipping, but the repair) I contacted seller. They are worthless also and I will never buy a product from
Woot.com again. Needless to say your product is garbage and I wasted a lot of money. I should have went with the competitor. I thought I would have received better customer support but instead I got took. I should have known better and trusted my instincts. Now I have a heavy paper weight that has constant batter errors asking for a restart. What a waste of money! Warning to all future customers. Go with another brand!
