    This little i2 (Hal) is my first foray into robot vacuums and I purchased it on the recommendation of a friend who has owned a number of different brands/models, including this one. I live in a 2 BD/2 BA condo with hardwoods and carpet. I regularly swept and vacuumed my place but would always turn around and see a dust bunny or clump of cat hair that blew out of some corner which bothered me and incentivized me to get a Roomba.

    Going on a month with Hal cleaning 3X a week, I have to say that I'm rather impressed with it. I was a bit worried during the first weeks when Hal was returning to his docking station 3 or 4 times during his runs to let me know he needed to be emptied. I was beginning to think that I was going to be catering to this device constantly and rethinking my decision to buy him. Turns out that even though I try to keep the place clean, Hal is regularly cleaning in places I never regularly attended to myself like way back underneath beds, under dressers and the like. Hal got me caught up on cleaning there. Now Hal needs to be emptied maybe 1.5 times on an average run, something I can live with.

    Hal does some things wonderfully like map out you living space and making sure to hit each and every corner and under every piece of furniture he can. On the downside, Hal does have issues getting stuck after running up the legs/base of my Barcelona chairs and will go all catawumpus until I go and put him back on a level surface. He doesn't the gradual upward slope of the legs. This happens on low bases of things like floor stand fans too. Hal seems to like to pull at the fringe ends of my Persian carpets too so these get shaken off and put up on an ottoman on days that Hal runs.

    Overall, I have to say that I'm pleased I bought Hal and feel that the rubber brushes do a dynamite job of picking up hair and detritus from both hardwoods and carpet. Especially carpet. I did have to make sure that charging cords, routers, carpets with fringes are tucked away, relocated or picked but this has helped me to make tidy up things too. If you're on the fence about getting one of these, I'd urge you to go ahead and get it. Ultimately it helps immensely in both maintaining a cleaner home and forcing you to declutter.

    Update: Several months in, Hal's dirt cannister is ~2/3 full after a complete run of my home. All in all, Hal was a good purchase and I think he'll last a good while.

    This cute vacuum works really well. It does get full about 3 times per cleaning session. But I only run it when I am home. Unfortunately it is not compatible with the empty tower so I will have to shop more carefully when I purchase my next one. My hair is long below my bra strap and I have to pull the hair out of the sweeper arms and the wheels. Other than that this little guy does an amazing job of getting all of the sand and dirt as well as dog and cat hair off the floor. I am impressed with this as it is my first robot vacuum. It has taught me that I need to look for other options when I shop for the next one. Like it does not allow me to send it to a certain location to clean. It just does it all on its own and sometimes when the dog bed is in the way it never makes it into the living room. I have mostly hard flooring and the living room has a rug. It has zero issues with getting into and off of the rugs. I like it so far but when I upgrade I will be looking into better options for sending it to certain locations to clean as well as being able to empty itself.

    Ricky the Roomba has been working for a month in our home now. He struggles sometimes, but the amount of vacuuming that I don't have to do…90% less!

    Ricky is really starting to learn the layout of the house and how to navigate our almost 1in difference in floor height between our kitchen and living room. This is an almost 30ft stretch so it was a struggle to learn it and where my lack of patience actually hindered his learning progress.

    Don't pick your Ricky up and move him all the way across the house when you get tired of hearing him struggle. Just move him a tiny bit so that it still understands where it is.

    I have 2 high shedding dogs and mechanic husband and Ricky really helps keep the main parts of the house clean. I close my office door and the extra bedroom and let him do his thing. We have a simple floor plan so the i2 works well for us. If the house wasn't an open floor plan rectangle then I would definitely want a higher end device to do smart mapping. '

    Overall worth every bit of the $200. (We also own 2 stick dysons – also worth it)

    We've had "Rosie" for over 2 years now and she does a great job. Have a mix of tile and vinyl plank flooring on our main level and she does great. After removing the carpet and installing the vinyl plank flooring, it was obvious that we had multiple cats. Constantly had cat hair in the corners of the room, but after this purchase you wouldn't know any better. We run it nightly overnight so we don't have to hear it run. It's a little loud, so this make it's easier on everyone as the bedrooms are on the second floor.

    We also us here upstairs on the carpeted bedrooms and it does a great job there as well. After market parts for the filters and brushes are great as well saving on the cost of the OEM stuff but otherwise a great product.

    Returns to charger by itself!

    We've had Roombas since they first came out, but our models have always been the ones you have to locate and return to the charger yourself. As we've got older, getting down on the floor to retrieve a Roomba with a broom from under the middle of the bed has lost its fun element. We love the way this newer model returnes to its base to recharge as needed and then resumes its cleaning program where it left off. Does a really good clean, too, getting all the cat hair and dust. The four Virtual Walls we already had with the old Roombas work just as well with the new one. We have two of this new model and can't
    recommend it highly enough.
