I bought a Shark from Sams 6 months ago and for some reason the it quit charging. I returned it to Sams to exchange it, but they didn't sell Sharks anymore. I then chose this Roomba to replace it. I didn't think, I would like it because years ago I had one that just bounced around with no routine. Well to my surprise this Roomba works so much better than that Shark did. It cleans faster and so much better. I really loved my Shark but since I tried the Roomba there is just no comparison in the cleanliness of my floors. I have an English Bulldog and he shed everywhere. I would run my shark twice to get the floors clean. My Roomba cleans with one pass and doesn't get hung up as much as my Shark did. I would buy again tomorrow if something happened to this vac.

Other than some minor issues with initial setup, usage of the vacuum has been almost completely hands free since I installed it. With the mapping technology and the vacuum base station, the i3 does a stellar job of cleaning, making its way back to home, and emptying its vacuum effortlessly.

After having the i3+ for over a year there were several things I hated. Although we have a large house it would take 5-6 hours to vacuum it and emptied itself and recharged a few times. It would also get stuck under furniture. I didn't mind the noise and loved that it emptied itself. I contacted iRobot and after a few emails they told me that's the way it is. I was ready to get rid of it and then saw that they added a mapping feature. I mapped our downstairs and set up virtual barriers. I then programmed it to do a different area every weekday. It now takes 30-60 minutes and does a great job. A friend came over and complimented us on how clean our floors are. I just bought another i3 for our upstairs.

My iRobot is powerful and does a thorough job. Even when my dog had an accident, my iRobot powered right through that pile of Poop over and over, trying to break it down and suck it up. It kept right on going over my living room carpet until eventually it made it to my kitchen, where I finally came down stairs that morning to find the fecal Jackson Pollock. After I got over the initial shock and horror, I was thoroughly impressed that in did not break. The design is pretty top notch to keep the sludge of poop out of the mechanics and battery. It was very easy to take apart and clean. It came with replacement rollers, brushes, and filter to make it even easier.

I set it to work on Mondays, Wednesdays, and Fridays at 9:00. He does a good job when he wants to, at least once a day, he gets lost, runs his battery down and i have to look for him, and with a dead battery , it is hard to find him. My first Roomba was smarter than this one. I gave it to my granddaughter and it is 3 years old and still working!!

Works great!!!!
