Cleans pretty well but bumps into everything. Other models I have seen have sensors that allow them to move around objects this one just bounces off like a bumper car. Guess that's why it was on sale.

Room a has worked without fail since purchasing last month. We use it on hardwood floors daily and the robot does a good job of keeping the floors clean. Great value for the price!

Purchased about a year ago. This Roomba did okay for about six months. Then it was in constant error mode for some reason or another and getting stuck in places that my old Roomba never did. Now it is just giving the same error and won't work at all even though we've followed the instructions.

I am enjoying getting our house cleaned while I am working on other tasks around the house. This little machine does a great job of cleaning. I would never trust it to clean when I wasn't home to supervise though, because it does get caught up on a few areas and more importantly, it can never find home to recharge. If I go outside for awhile I have to search to find it if it dies during a cleaning job. Also, it has yet to develop any kind of routine for cleaning. It wanders around for a couple of hours. Eventually it gets almost everywhere it is supposed to, but I have no idea how it determines where to go.

Total Junk. Spend the extra money and buy one of the "i" series, you'll be glad you did. This vacuum basically operates like a ping pong ball that randomly bounces around your house. It gets lost every time and can't find its base, so the battery dies and you find it randomly around the house. This vacuum also frequently gets stuck. The canister does not hold enough for the vacuum to clean the 900 or so square feet I require. I purchased this to aid in efficiency around our house, ultimately it added another task each day.

I The unit doesn’t hold a lot of dirt and would go for a little bit and then stop, with an error message. I would clean the rollers and a little bit later, same issue. Needless to say, but I returned the unit to Sams. Too much money for something that doesn’t do as it is supposed to.

We had this item to keep our solid surface and carpet area clean. The unit did pick up loose dirt but never covered the entire available area. It would cover one room then return to its base with an error When I returned home and heard the portable battery operated unit working I knew the device was too expense you to keep I returned the into to Sam’s for a refund today!

We use the Roomba in our bedroom. It does a very good job vacuuming, but rarely returns to the base. It gets stuck somewhere most of the time. We have an adjustable bed which has several “legs” under the frame and it generally gets stuck under there. This Roomba does not use navigation and just bounces around semi-randomly (aside from edges which it tends to follow). It bounces back and forth between the bed legs and can’t find its way out. Would have given it 5 stars for its performance otherwise. Would be great if you don’t have Chairs, beds or other furniture around where it can get stuck.

I love the Roomba. I named him Bob so I could use my husband's name and the word "vacuum" in the same sentence. I thought our house was fairly clean. Then came Bob. He manages to find dirt every day, but he goes places other vacuums and brooms can't go.

This has been a great help for since I don’t seem to have a lot of time lately. It does a great job from what I’ve seen. You do have to go around and check for problem area’s or basically puppy proof or Baby proof the house. Other than that it has been wonderful. You do have to dump it’s bin after every use which isn’t difficult after the first time figuring out how to do and blowing off the filter and wiping down the unit every now and then
