Query: Remanufactured? No Thanks.

Love those Irobot products and everything they're capable of doing. In fact, this was my third purchase, but my first remanufactured product. What a headache! The product worked correctly just three times, then died. Both technical support and customer service from Irobot were helpful and prompt, but still took weeks to resolve the issues. I tried a different way of recharging, which didn't work. Then they replaced the battery, but that still didn't solve the problem. Ultimately I had to send the product back, then waited more than a month for a replacement, which was on backorder. Finally, they substituted a different model, and which works just as advertised. I'd never buy another remanufactured model. But I still believe in Irobot.
