There are many different brands of vacuum robots out there- ranging from $200 to $800. Roomba being very well known brand catches more attention.This is Roomba's entry level vacuum robot, meaning also least expensive of their lineup, which also means the minimal features.Depending on your requirement and budget, hope you find my review helpful to decide if this is the right product for your needs. I would say - requirement is very important to understand as that may allow you to pick the right product.First, I would like to share my test in different rooms.To test this robot, I let it loose in my bedroom that needed some serious floor cleaning (dust and hair stuck on the rug). I have rug underneath my bed, 2 side tables, 1 dresser, 1 filing cabinet and 1 ikea cabinet with 3 doors. I removed every other item such as fan, iron board etc from its way. I set up the dock and released the robot. I was in the kitchen cooking. It got stuck only once underneath side table for which I got a notification on my phone (Irobot app). The end result - A FANTASTIC JOB. I am more than impressed! Except 1 corner the room was spotless, the rug is nice and clean. As you can see in the pictures posted, the prompt that my roomba is stuck and needs help and the time it took to clean the room. When I went up to check, the robot was back parked on its dock! Next few pictures show the amount of dust and hair extracted from the floor and the rug. The hair were all tangled in the wheel and it took few minutes to clean it all out. All the parts are easily removed for cleaning which is a BIG +My living room was a different story. Why? Because my rug has black patches and it just completely avoided those area and got stuck and would just randomly stop.My kitchen - cleaned it super well from end to end - all the edges. I cannot specify enough to remove all the items from the floor- such as chairs, shoes, wires, toys, etc. The more open space it has the more better job it does.My observations--light weight - comes with a handle to easily move from one room to the other-The clean pattern is zig-zag and it's own algorithm, but it does try to cover as much area as possible.-If you have pet that sheds hair, you will be SO HAPPY with this robot :)-If it finds area with more dirt/debris, it will try to clean multiple times.. does it pretty well-So far it has done great job in coming out from under the bed, sofa, table- has stuck only onceIt also seamless move from floor to rug. It has avoided stairs, but it just stops. So, I have to move and restart-The battery life is great- I have done room after room and does not need a lot of time to recharge-I have open room concept with no doors on the main floor, so I create barrier so that Roomba stays in one room. You can either buy virtual wall from Roomba or put boxes, books etc. You can also try a piece of black rug - as it seems to avoid black!!-This Roomba is Wi-Fi ready and also easily integrates with Alexa/ Google. Through Roomba app, you can create your schedule when you want to run it and operate it remotely. I have seamlessly used Alexa to start, stop and return to its base commands. Check out my video- Many third party parts are available such as filters, brushes, rollers etc at a reasonable cost- Cons-I feel the power is not enough to collect everything - 800+ series uses 5times more power- The rollers are not tangle free - Hairs get stuck onto the spinning - so frequent cleaning is necessary - Upper models offer tangle free rollers-filters are not high efficiency-No advance navigation system to help with multi room - which means you will need to move Roomba around yourself - or else it will get lost and might not clean all the areas.-It won't recharge and resume like the upper costlier models-It may be difficult to thoroughly clean small tight spaces such as bathroom or passages-It DOES NOT come with virtual wall. You will have to purchase as extras. And make sure you purchase that is compatible with 600 series!TIPS:1) Before you run your Roomba try to have your floor clean of toys or clothes lying around as it can mess up the machine and change directions.2) Empty your dust bin daily and clean all the parts. They easily come off for thorough cleaningDespite all the cons, I am extremely happy with this product because IT SAVES TIME and keeps your floors super clean. While I am cooking, Meera (yes you can name your Roomba :)) is actively cleaning my rooms. It does such a great job that I may not even have to do my weekly vacuum. The reason I am giving this 4 star is because of hair getting tangled and roomba not able to clean my living room because of black patches.The video shows my command to Alexa and how wonderfully it works(see how it avoids black patches on my rug) . You can make it work while you are doing other chores, out of house, program it to run at specific time or just do 1 room a day! In my opinion you won't be disappointed.If you have any questions, please let me knowIf you find my review helpful to decide if this product is a right buy for your needs or not please click YES button below.
