Great Value. But don't even think about buying a roomba without that storage tank. Our house is large, but the roomba runs out of room 3 times in one day of cleaning. It's fine with the tank because it will go back to the base and empty itself and keep going...but man would I be frustrated if it did 1/3 of the house and I had to empty it every single day.

Easy set up! Let it map home then i can divide up rooms and assign names. Set it to do house when i leave home. Come home to clean house everyday! Wife loves it.....Happy Wife Happy Life!

Didn’t work well for us. Was going all over the place. Had to watch it like a kid because it would constantly get stuck and was very loud. Sometimes I think reviews on items are staged. This item was not even close to what reviews said.

This iRobot Roomba is a dream come true. No more messing with dust and dirt. It does sound like a jet taking off when it empties, but other than that just program it and forget about it. I always have clean floors now and it is wonderful!!!!!

2 golden retrievers. With the older first generation I had to go behind it a vacuum a second time. Took a shot with the new self cleaning model. No clogs. No second vacuuming session. It works excellent. Huge improvement with mapping and coverage. The added bonus, is that it’s MUCH quieter than the old model.

The Roomba i3 3556 is fabulous! Henry (that’s what we named ours) comes out at 3:00 am and vacuumes the first floor in and hour and a half, takes himself home and empties himself. The only thing that we have to do is keep the filter clean and the sensors, ends of the rollers and wheels clean of pet hair, all quite often. Henry does get “stuck” on our black registers sometimes (something about Black makes this happen, but if you keep the sensors clean it helps) so we put dining room chairs over top of them to keep him from rolling on top of them. It may seem like it’s roaming aimlessly at first, but it does establish a pattern and it gets the job well done. You can control it from your phone.

Overall I’m glad I made this purchase. It does take longer than I expected to vacuum which can be inconvenient at times. We’ve been using the Roomba for a month consistently and have had a few hiccups but have always been able to resolve them. I do think there’s somewhat of a learning curve. I do love that I can turn it on when I leave home and come back to clean floors. I do have to remember to move the dining room chairs, for example, if I know I want the Roomba to vacuum that day.

Ii love my I3+ room a. It’s the best of 5 I’ve bought! It’s smarter than I am! With several cats and dogs traipsing through the house, it’s absolutely necessary to keep the fluff at bay. My floors have never been so hairless! Oh, and my kittens are mesmerized. Great feline entertainment.

I like the i3+EVO now, but not when I got it home from the store. I was disappointed when I open the box and found no manual with in the box. I have to ask my grandson to help and shown me how to operate and what were the use of each function on the machine. The second I was disappointed is Sam's does not sell the refill bags? Is it make sense if sam's is selling the machine should Sam's makes the refill bag available for order?

We’re tech savvy, but this was the most frustrating device we’ve ever purchased. “Empty bin” error message would not clear. There’s no manual, everything is online. Spent way too much time watching the YouTube instructions…..that didn’t clear the error.
