Purchased mine refurbished from Amazon June 15, 2017. As of writing this, it is December 14, 2019 and my roomba is still working without any hiccups. I purchased a two year warranty on it through Amazon and never had to use it. I have been pretty vigilant about changing the two brushes out every 1-2 months. I change the side brush out as needed as well as the bin filters. These replacement parts are inexpensive and worth keeping the roomba working properly.
Right in the beginning, I thought the side brush module had broken, and roomba sent me a new one. I never replaced it, it just started working again. I learned to take it apart though and pull the hair our of it to keep it running better. Today ... I realized the side brush module actually WAS broken this time. The white pin that holds the brush was unstable and caused the side brush to grind as it went. Since I had a replacement on hand, I went ahead and changed it out (which was super simple). I blew out the insides while the bottom cover was off and changed all my brushes. Put it all back together and it runs like a champ again.
I purposely sought out the 770 for it's features. The specific roller brush, the HEPA filters. This was always the one I wanted. The lower models and the higher models did not have all the features that this one had that I wanted. I have had no regrets on my purchase. I would probably consider buying the 770 again, and not a new model should this unit ever take a turn for the worst.
Our household consists of one steady inside cat with 2-3 that come in and out. Plus, my husband got a truck dog this year so when she is home she is an inside animals. It blows my mind each time I empty the bin. I am like "all this came from our house?" I am surprised how much junk this picks up and we don't even wear shoes in the house.
I will also say ... contacting Roomba, which I think I did twice, was always a pleasure. They were always helpful and kind.
What can I say? 2.5 years have gone by and my vacuum still runs like a champ!

7 years and counting! Go Rosie... Go Rosie!
Rosie was the robotic maid from the Jetsons, my kids named the Roomba Rosie. This is my first Amazon review. Usually I speak up when a product fails. In this case I am really impressed that this vacuum runs 6 days a week in out house for just past 7 years! I wish more electronics were made to last this way. Good job to the engineers at iRobot! Well done. Thanks to Amazon history I can see I've replace dates battery, brushes and recently the side brush motor for $40. but it still works well. I emptied the hopper last night and it was full. Something oddly satisfying about seeing that clear bin full of dirt. I love the way it goes under the couch, dressers, beds, etc. and gets those hiding dust bunnies. Hope you find this helpful.

I hate to say "it's changed our lives" because that sounds like marketing crap, but it's changed our lives.
