The world needs to know of the Roomba's greatness.

Summary: Lets first address the question that we all have asked ourself when contemplating the purchase of a robotic vacuum, "this thing can't actually work, can it?". The definitive answer, without a doubt, is YES IT CAN!!! This Roomba is awesome- plain and simple. Buy it. Just do it. You will be glad you did. It is no joke, and it is not a toy (although my dog seems to think it is). It's great. It's wonderful. It works.
Summary: Effective sweeper, reasonably efficient in coverage pattern, easy to clean brush mechanism. The side sweeper is a simple but helpful addition to the main brush action. The price range is reasonable for a device that has four guidance sensors that seem to take it on an intelligent route. I don't have pets, but the Roomba does a first rate job on cleaning my carpets of debris left by humans. .
Summary: Wanted a Roomba FOREVER. Finally ordered this model. Wasn't aware that it lacks the programming feature, but after a few days I didn't even care. I would never use it, and here why: Sometimes I leave soda cans etc on the floor in the living room or a bag of garbage by the front door, and not having the programming gives me time to pick everything up before I run the vacuum.
Summary: This is our 7th Roomba in 9 years. Sounds like they must not last, eh? Well, we have 2 dogs, 2 cats and a parrot with copious dander. Thus, we keep at least one Roomba running 8 - 12 hours a day. Seriously. So, we've just worn out the 400 series. We have the 630 and the 650. Both are huge improvements over earlier models. The motor and inner electronics are now fully encased, making it harder for hair, dust, etc. to clog up the works.
Summary: It ran for about 15 minutes and then quit. Unit is very loud while it did run. Customer service sent out rear wheel modules for me to change. I replaced them, did not work. Customer service is horrible. Returning this unit and getting my money back.
