Powerful Cleaning - Scheduled Around Your Life
Whether you’re relaxing at home or out enjoying life, the Roomba i3+ EVO robot vacuum takes care of stubborn dirt and messes with a Premium 3-Stage Cleaning System and 10x the Power-Lifting Suction*. *Compared to the Roomba® 600 series cleaning system
Clean by Room, You're in Control
Roomba i3+ EVO learns your home and creates an Imprint Smart Map so you can direct it to clean any room you want, any time you want—either on a set schedule or in the moment.
Don't Lift a Finger for Months
Now you can forget about vacuuming for months at a time with the Clean Base Automatic Dirt Disposal that allows the i3+ EVO to empty itself into an enclosed bag that captures 99% of particles as small as .7 microns and holds up to 60 days of cleanings.
Precision Cleaning in Tidy Rows
The robot vacuum cleans intelligently in straight lines back and forth, to thoroughly clean your floors while navigating around furniture. When the i3+ EVO needs to recharge, it will resume right where it left off ensuring a complete clean.
Focused Cleaning You Can Count On
iRobot's Patented Dirt Detect Technology allows the Roomba i3+ EVO to detect dirtier areas of your home and clean them more thoroughly. Integrated sensors tell the robot where it can and can’t fit, so it doesn’t get stuck under furniture.
Perfect for Homes with Pets
Instead of using a single bristle brush, Roomba i3+ EVO uses Dual Multi-Surface Rubber Brushes that flex to adjust to different floor types and avoid getting tangled with pet hair.
Stays One Step Ahead of the Mess
The i3+ EVO learns your cleaning habits and can offer up suggestions—even suggesting extra cleanings during peak pollen or shedding season.
Clean by Voice
Start cleaning one room or every room with Google Assistant and Alexa* and let the robot take care of messes in the moment. *Works with Google Home and Alexa enabled devices. Alexa and all related logos are trademarks of Amazon.com or its affiliates. Google is a trademark of Google LLC
Flexibility to Clean Around Your Life
The i3+ EVO can be set to automatically start cleaning when you leave and stop when you come home. And with Cleaning Time Estimates Roomba tells you how long each room takes to vacuum in the iRobot Home App.
Getting Smarter & Smarter
Quality that lasts. Intelligence that grows. Your robot vacuum gets new features through automatic software updates—for a smarter level of clean.

Highly recommend!!!
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I should've bought this roomba way earlier. Works like a charm and does what you want it to do. Easy to use and set up. It maps your home and updates itself with every clean so if you need certain room cleaned, it'll get the job done fast and effectively. The Roomba itself is quiet, the only noisy part is when the Roomba is dumping all the dirt collected into the base, and even then it's only for a few seconds. It also pairs with Google Home and Alexa to make things even easier for you

Looks pretty modern and sleek, It's a great helper
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Honestly this is very useful especially if you ever think you're gonna be lazy or just don't want to always clean up or or you're very busy this is very convenient and does everything you need to do yes it's not perfect there's way higher end models that do an amazing job, But the price to performance especially if you get this on sale it's really good does exactly what you need it to do it gets around corners yes it does sometimes get caught on cables but most of the time it doesn't, pretty good job and sometimes can go around it or over it, The reason why these rumbas specifically do a better job it's because of the bottom has 2 rollers to Collect any dirt then regular vacuums that have one single roller, And if you're wondering about animals it does just fine if you have a dog that sheds a lot more that has very thick hair you might need to change the bag every so often maybe once a month if not it could probably last up to 2 to 3 months for one bag depending on your floor how dirty it is not bad for price, Esthetically it looks pretty good it looks modern and even on tight little corners wherever you set the home at it's pretty easy to use on the app and Can find itself to go home when it needs to empty the bin and continue its job even if you put it in a corner, Hopefully this helps somebody out there!

Excellent after learning curve
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Its quite remarkable how well this can create a map without the use of cameras. I dont like the idea of having a camera on wifi going around my house. The learning curve for the robot is about 3 days, about a week for me in terms of figuring the device out. People are having problems that are easy to fix. A little time on youtube helped me learn how to clean the bag full sensor which is a common problem. Wise words of advice are take care of your machines because they take care of you (cleaning the bin is easier than cleaning the whole floor) It gets tons more dog hair out of my carpet than i ever have without ever clogging (husky german shep mix) but the bag does get full quickly. Id be very interested in a reusable bag since i used 3 in the first week which is pricey. Seems like a way for the company to generate more profit, i get it. A small hook can help you pull the hair out of the bag to keep reusing it. All in all this robot has massively improved my life and is worth every penny. Fixing its small issues is much less time consuming than actually vacuuming the entire house yourself daily. This model has the same brushes and motor as the higher end ones!

Amazing vacuum at an amazing Black Friday price.
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love this smart vacuum. Was worried with having a dog the vacuum would not fully clean my home but I am really amazed. I have it run once a day and it dose a outstanding job. I love the fact it has a smart tracking feature and shows me where it was and where it had to spend a little more time with a deep deep cleaning feature. It will not fully replace your standard vacuum but will make it feel very obsolete only needing it for places the iRobot i3+ cannot reach. The vacuum is nice and quiet but still able to retain amazing suction the loudest part about this device is when it empties it’s self and sounds like a jet taking off I may be exaggerating a little but it is loud. With a sales tag this Black Friday of $399 without a doubt was worth it. It may not be as smart as the i7 with the room mapping but again at that price worth it. In conclusion this is one of those moments when I actually asked myself why didn’t I get this sooner.

Alexa, tell Rita to clean the house.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I could not be happier with the product. It was a splurge. My iRobot name is Rita. She mapped the whole floor area after a two separate passes. She occasionally bumped into furniture while mapping but it wasn’t aggressive. Eventually I would dim the lamps, overhead lights and watch it shine the flashlight brighter and brighter to be able and see the area. After a couple time it began learning the area and would remove itself from the base and take off. When it approached an object it will slow way down and just as it is within inches it gentle touches the object and final learns to avoid it all together and move around it. A perk to me is the mapping. You are able label rooms and even set some spaces as off limits, so no closing the door, etc. A great thing for me is it works with Alexa and my phone. Alexa, tell Rita to clean the house. I still get a charge out of that. Oh, one last thing. I’ve seen reviews that read when docking and disposing of dirt the vacuum should like a turbine engine. Not to my ears. I hear something along the realm of a shop vac. I get around hearing that by scheduling cleaning while I out. I’m sure you’ll enjoy the purchase as much as I do.

LOVE IT!!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We have a Dogo Argentino puppy who is shedding like crazy. Now I’ve owned my fair share of big dogs but have never had this much shedding with any of them. I run this roomba 3x a week at night while we’re asleep and then the night before I do the floors just to save me some time. We have travertine floors and a 3500sq ft house. I just did the weekly maintenance on the device and you can CLEARLY tell it’s working. It’s even picking up my hair, my daughters hair and my sons girlfriends hair. It’s also been raining so the dog tracks in so much dirt. Trying to convince my husband to be me the mop device now! Lol You won’t regret buying this. We do have two area rugs that it goes over and it isn’t the best on the rugs when it comes to the dog hair but is works for the crumbs my 4 year old. I’ve been trying to convince my best friend to get one. She is like me and has a pet peeve about dirty floors. Once the vacuum bag is full I plan to cut it open to really see how well it’s been working but I can tell by looking at my floors that it’s a game changer! You do have to buy vacuum bags and filters. I just had my husband blow the filter off with our air compressor and it looks brand new. If you keep up with the maintenance I think it will last you much longer. The add on’s aren’t expensive tho.

Q: QuestionHow do you get it to automatically or self empty? Mine seems to need me to hit the empty bin button on the app to perform this "automatic" function.
Asked by briand.
- A:Answer I figured it out. It only seems to self empty if it makes it home on its own. My previous runs it got stuck and couldn't make it back and when I docked it manually it didn't automatically empty even though it was full.
Answered by briand
Q: QuestionAny issues with stairs? I want this for my second floor which is all carpet. I'm afraid it will fall down the stairs.
Asked by Bailey.
- A:Answer The Roomba i3+ has Cliff Detect Sensors built into the robot to allow for a whole home clean without worry of falling down any stairs or submerged living areas. The robot will detect the drop off, move away and continue cleaning.
Answered by iRobot representative
Q: QuestionCan the bag inside the docking station be re-used? Can I empty the bag into the garbage and put the same bag back in?
Asked by Marsh3423.
- A:Answer You could but they were not designed for reuse. When you pull the bag out, you pull up on a tab the closes off the opening to the bag. There are after market reusable bags available from third parties.

Q: QuestionDo you have to have internet for this model to work
Asked by Anonymous.
- A:Answer No. You can run it without WiFi, you just won't be able to enjoy all the features that come with app.

Q: QuestionHow large of an empty space can this handle? I have a 1700-sq ft space that's empty. I like my little Roomba 614, but it keeps having an existential crisis if I don't litter the floor with heavy obstacles to let it know it's not alone in the universe.
Asked by Harry.
- A:Answer The i3 should have no problem navigating an empty space. It will clean until its battery is too low to continue and will then go back to the Clean Base to recharge. Once the battery is sufficiently charged it will resume cleaning. The i3 will repeat this process until it has determined that the entire space has been cleaned.
Answered by iRobot representative
Q: QuestionWhat if the robot hits liquid
Asked by EdH.
- A:Answer We have 5 dogs, 4 of them are old and accidents happen. We also own 6 roombas. 2 with the disposal systems. I usually only run the roombas when I am at home, or the dogs are outside. It happened a couple of times that I did not see the little accident until I saw the streaks of pee all over my floor. Only a mop and bucket will help that and you have to take the roomba apart to clean it thoroughly. That is the only downfall. I love my roombas. Could not keep my house as clean of dog hair and the dirt they bring in without them. Just watch for any liquids.
Answered by Roomba
Q: QuestionDoes this vacuum work on carpet and floor?
Asked by Debbie.
- A:Answer That is correct! The Roomba i3+ is designed to clean both carpet and hard floors like hardwood or tile. Which the i3+ is able to transition between the two. Meaning that items like area rugs are able to be vacuumed or going from room to room.
