Context of this review: First time buyer of any model of IRobot Roomba vacuum. Purchased the J7+ that includes the robot and the waste station. I do like it. It is not perfect but after a couple of days of use, I am impressed. There is a learning period for both myself and the robot. 1) First off, after unboxing, put the station in and put the robot into position to charge for a few hours. While charging download the app to your phone and connect. Read the user manual about how the ring light on the robot works. It is context based - charging, vacuuming, etc. - and means different things based on the context. 2)The light on the waste station is peculiar and does not stay on when plugged in and charging. Nor does the light on the robot stay on when charging. There is a momentary initial light on each. 3) I should have read up on from their support website about Smartmaps first. After a full charge, I let the robot run through the first floor of my home. On the initial pass, It was able to do about 2.5 rooms before it needed to be recharged. While recharging, I mistakenly cancelled the initial full floor job. It worked out OK after the second full floor job - completing the first map and a new second map at the same time. Be prepared to walk around with your robot to train it where not to go. I was able to use the pause button on the phone and the top button on the robot. However, it may be better to hit the sense bars on the robot to initially avoid areas while you create the first couple maps. Subsequently, I plan to mark out the no-go zones. 4) Apparently, the position of the charge station is very important. You may want to plan this out in advance even before buying. The station needs to be near an outlet and have a clearance on each side of 1.5 feet, more distance is required if near a stairway. I am not sure how this effects your first maps if you move your station to another location on the same floor. iRobot advises getting a second waste station if you move your robot between two floors - one station for each floor. Clearly, the station position is important for the robot to know. 5) Preparation of your home for the robot can be important before using it. Pet food bowls, electrical cords, and floor mats are some of the things to consider. I found the robot had problems with a raised fireplace hearth. It was low enough to try to go on top of it but had trouble negotiating while trying to vaccuum along the edge. The fire place hearth is one area I plan on giving a no-go zone to, as well as the pet food bowls. Because preparation is needed, I am not sure how useful scheduling is going to be, unless you have a sparse home with no pets and little moveable furniture. 6) Maintenance - While on the first job ever, the vaccuum managed to wrap a cat play string around the rotating brush. I had to stop the robot and unwrap the string. (note to self - pick up all string) There was also cat hair around the rotating brush in the in joints of roller shafts that also needed clearing. I can see how maintenance is going to be a recurring thing with the robot, when you usually ignore your upright vaccums, but for emptying its bag and cleaning filters. Maintenance costs are going to be more than your upright vacuum, which you may want to consider with the upfront purchase costs. 7) Cleaner home? With hair shedding pets, I can see how one's home may remain cleaner if you regularly run the robot. The robot can also run under some things (some couches, some cabinets) where you cannot vacuum with an upright. However, there are likely to still be some areas/rooms where you don't want to run the vacuum robot - areas near food bowls, cat litter boxes, and bathrooms. 8) With a camera on the front of the robot, I think there is much that the irobot can do in programming it to clean better and navigate better. 9) I have much to learn about using the robot due to my inexperience. However, I think I can make this work to keep my home cleaner.

Roomba does not have LIDAR navigation. I do have another robot that is LIDAR so I can give a rough pros and cons of the two type of navigation system. Roomba relies more on bumping into things and it's map to navigate. There's good and bad. The bad is that it will often go around the house as if it's a drunk bumping into furniture and objects. The robot needs to learn your floorplan and that can take a long time since it's bumping into everything. It took me about 5 runs of my whole house. Each run took about 3 -4 hours since my house is 2500 sq ft. Prior to it learning my house, it's navigation looked like it was non existent. I thought I had just bought the dumbest robot especially compared to my inexpensive $300 LIDAR robot. However, once the robot declared that it had learned my floorplan everything changed and I began to see the benefits of the iRobot navigation system. Even after learning my floorplan, the iRobot still takes forever navigating around table and chair legs. Bumping and taking multiple attempts to escape the forest of chair legs, but surprisingly, it has never gotten stuck in my house. I have set it to vacuum my entire house several times and in total it has vacuumed about 20,000 sq ft in it's lifetime so far and it has never gotten stuck. We have kids so there's a lot of toys and miscellaneous items everywhere so that's amazing to me. My LIDAR robot on the other hand navigates beautifully around furniture but it can't see cords or other lower to the ground objects and it constantly gets stuck on these objects. Also because LIDAR isn't bumping into things to navigate it gets stuck under my couch because the fabric under my couch sags and the LIDAR robot will travel underneath the couch but then think it's blocked in by the fabric when it tries to leave the couch area. The iRobot doesn't have this problems because whenever it's in doubt it just goes barreling through and utilizes the bump sensor to feel around. The other problem with my $300 LIDAR unit was that it would sometimes do a cleaning run but mistakenly think that there is a new floorplan and erase the old one. It's more sensitive to changes because it's LIDAR hardware can detect small changes. This is probably more a software issue. The iRobot on the other hand, is very hesitant to change it's map. That is good in that it has never erased my current floorplan or made incorrect modifications, however, the initial "learning of the floorplan" is a bit harder if it doesn't discover all your rooms. Getting it to discover new rooms is more difficult since the floor plan is locked in. I've found the best way to get it to discover new rooms after it has "learned the floorplan" is to do an area clean and just draw a box where to new room should be. Once I did that, it would explore that area and declare it found a new space and then it was added to the floorplan. A few other more minor issues is that the Roomba software is polished but also very limited on options as compared to my inexpensive LIDAR unit. For example, I can't set how often the Roomba should self empty or the quiet times (they removed the beta feature for quiet times). These are important features since the self empty dock is very loud. Much louder then my LIDAR robots self empty dock. I'm not that sensitive to noise. The noise level is just a design flaw. I can't imagine going forward they will keep this design. If you live in a small apartment then you should definitely be aware that you will be disturbing your neighbors or yourself when it self empties. It's louder than my large shop vac.

01/02/2023 Update: I just had to provide this update for Anyone thinking about buying an iRobot device. Today I sent my J7 roomba out to clean the back bedrooms - which it has done on an established map many times before. On the first try - it wandered aimlessly, went back to the base station after 15 minutes and said "all done". NOT possible - the run time is typically 70 minutes - so I sent it out again. After 20 minutes it said "localization failed" - meaning this More Onic thing could not find itself on the previously established map. So - I sent it out a third time - which proved to be the charm - as it then completed the cleaning task. Of course because of the cheap battery (iRobot chose to send this vacuum with a wimpy 32 watt hour battery - oh yeah - for an additional $20 on this $600+ product they COULD have included a battery with TWICE the capacity - but Nooo- their hand in your pocket) it had to return to recharge after an hour, then completing the task in another 7 minutes. Just as another FYI - I'd previously noted a thin nylon line protruding from one of the main drive wheels. I am a pretty accomplished do-it-yourself-er, and after finding details on FixIt, decided to open the thing up. It is really quite straight-forward, BUT - the drive wheels were designed on purpose to prevent you from fixing them. The last gear on the drive wheel is pressed on over splines, requiring a lot of careful pressure for removal with a flat blade screwdriver to avoid destroying the gear. And even then, the wheel does NOT want to come out of the housing - I suspect because of the splines. Using 2 screwdrivers (one acting as a block) I was able to develop sufficient space between the wheel and the housing to remove the nylon tag, as well as a bunch of debris that had developed over the past year. Reassembly was a snap, and we were off to the races. As a part of this fix I needed to remove the bottom cover. After doing so, I noticed the battery only partially filled the battery space (see photo)!! The battery capacity on the OEM battery is listed at 32 Wh (watt hours), or 2.22 Amp Hours (Ah). Many on-line battery supply houses list replacement batteries up to or exceeding 5.6 Amp Hours - or almost 3 times the run-time of the OEM battery. Buyers scammed by iRobot again !! 10/19/22 update. One of the poorest performing mapping robot vacuums I've ever seen. Despite being in use for almost a year, it continues to bump it's way along the room maps - almost like it's never been there before. In addition, I've been unable to figure out how to add an unmapped closet to the current map. Just leaving the closet door open - the thing just pokes it's nose in, then ignores it. Battery life is pretty poor - it'll vacuum for about 1 hour, then needs to recharge (no change compared to when new). It sees wires hanging down along a wall, and marks them as obstacles, avoiding several feet of carpet in the area. Even on a new job - upon identifying - say a chair leg - it fails to remember that, and bumps into it over and over again. It takes over 30 minutes to vacuum around our kitchen table with 4 chairs. Although I like the self-emptying feature, most other robot vaccums offer the same. I found our previous square nose vacuum did a far better job in corners. To add insult to injury - when I made several suggestions to iRobot on how they might improve their mapping system, they pretty much yelled at me for making suggestions, claiming they could never use those suggestions as it might violate 'intellectual property rights'. When this thing dies, I'll be going back to Neato - or possibly Shark. Roomba i7 Mapping Fails (4 mapping runs and 2 vacuum all runs) (12/31/21) Very discouraged. Got a Roomba i7+ (Auto Bin Empty) for Christmas (actually well before but ran it several times to be sure it worked). I sent it out first on a mapping only run - and it ended with the expected first-run 'mapping in progress' notice. Sent on a second mapping run - same notice. OK - sent it out on a vacuum all run - error message = unable to complete vacuum all as requested (map still 'in progress"). Sent on the third mapping run - ended with the 'mapping in progress' notice. Second Vacuum All run - "unable to complete all as requested" (Mapping still 'in progress). 4th mapping run - ended with 'mapping in progress'. Sure - we have a 4400 SqFt home, but the Roomba reports only 1700 SqFt mapped. Watching the device - it shows NO EVIDENCE of having been there before - running the exact same search pattern as before, bumping over and over into the same objects it encountered in previous runs. It was unable to detect the 1-1/2" step-down into our laundry room (hung up there until I placed a barrier in the way (it failed to recognize my magnetic no-go strips)) Any suggestions would be appreciated. Given the size of my one-story house, I will close doors and otherwise create obstacles to make 3 separate maps. I spoke with iRobot Customer Service who confirmed that was the right approach. Reposition the base station within each of your 3 maps and create a unique map for each section of the house. When you want to vacuum that area, put the base station in the spot where mapping was begun, select the map of that area, and initiate cleaning. Kind of a kludge, but we can make it work. No excuse for them NOT including a simple hall effect sensor for magnetic strips.

It can be a b*tch to setup. But I LOVE my Roomby! It works great with dog hair, hardwood floor and our carpets. I have animal allergies (its a cruel joke, because I am a hardcore dog fan and we have the sweetest most perfect Greyhound ever.) I was having to spend an incredible amount of time vacuming. After using Roomby I don't have to vacuum our laminate floor multiple times a day or even daily. Although the floor can't have sticky bits, or the Roomba will just spread it around! It works absolutely perfectly for pet hair/dander and human hair/dander! My dog has very coarse fur (think the texture of Chihuahua hair except much longer) and sheds much more than you would expect for a Greyhound I'm taking off one star because it once fell down the stairs, and if you unplug it, it can be frustrating to setup! I will say it is VERY good at avoiding items. My dog with be walking around and it completely avoids her! Saves me a lot of time! Tip to remember as you are setting up-it does not connect to 5g networks (I don't think anyways.) and it has to be connected to the same wifi as your phone! So make sure your phone is connected to the non 5g network before starting!

I purchased an off brand robot vacuum a couple years ago when I moved into a new home with all laminate flooring on the first floor. It was a huge disappointment. I finally decided to spend the extra money and purchase this roomba. I have long hair that constantly sheds, 3 cats, and a messy partner with his equally mess 12 year old son living in my house. The mapping function is really cool. I love that I can set up difference spaces and say I just want the kitchen done or I want the whole first floor. For the most part, the roomba covers all designated areas. Really cool function: after a cleaning session, roomba sends me pictures of obstacles asking for feedback. I have to confirm it’s a true obstacle and have the option of saying it’s temporary or it’s a keep out zone (eg peloton cord area). I can also tell roomba it’s drunk and that’s not an obstacle and to go back and clean the area. It even sent me a picture of my boyfriend’s shoes so I knew he didn’t move out of the way for roomba 😂. Technically it’s supposed to spot solid piles of waste and avoid (I’m thinking cat vomit). That being said, I do a quick visual sweep because I’m not sure I trust it especially for small and flattened vomit piles. I’ve read some funny but horrifying reviews about other roomba models going over dog poop and painting the house with it. Not worth the risk to me and I will only run it when I’m home, despite having the option to do otherwise. It always finds its way home. My other brand struggled with that. It auto empties too which is nice. Only downside is I have no idea how much dirt it is or is not collecting because the bag is sealed. Guess I’ll find out after 60 days? App works great! No complaints. Couldn’t even get my last brand to work on the app. Biggest negative is noise. This is not quiet. Not as loud as a regular vacuum, but enough that you likely won’t run it while sleeping. When it empties its bag, it literally sounds like a plane taking off. The cats HATE that part, but they survive. Bottom line: if you are looking for something to effectively do light clean up on days between deep cleans, this will not disappoint. If you are expecting to never vacuum or mop again, this is not for you. I would definitely recommend this to anyone with pets, kids, or is just kind of messy and wants to extend time between deep cleaning. Disclaimer: I have only used on laminate floors and a low pile rug. I cannot speak to how it works with extensive carpeting.

I've had the j7 for about 3 months now and I am very pleased with the performance so far. tl;dr: If you're thinking about upgrading, do it, you'll be happy with it. Previously I had an e6, which worked well, but after about 3 years of running twice a day (I have 2 dogs that shed quite a bit) the rotors stopped working. So instead of fixing/continuing with the e6, I decided it was time for an upgrade. Things I'm impressed with so far - The floor mapping / cleaning AI cleans better than my e6 that just bounced around via an algorithm - Self emptying bin is awesome (I still check the roomba's rollers, brush, and bin periodically to untangle hair, etc) - App has info on when you should replace filter/brush/rollers (didn't see this for my e6) - Base station: Having a flat base that the whole unit drives up on ensures that the charging contacts are aligned. My e6 would occasionally have issues with docking properly. - Obstacle Avoidance: This model will try to identify obstacles and will take pictures of them that you review in the App to help the roomba learn to clean better. So far it has been very intuitive. Things that could be improved / wish list - AI still seems to have a little wonkiness to it. Ironically, I think my e6 navigated around dining room chairs better, but the j7 still gets the job done. - I wish that there was an option in the App to save the pictures of obstacles to your cameral roll. It took a couple hilarious pictures of my dog that I would have loved to have kept. - Zones: When you name a Clean Zone, you can only pick from a list so you can only one zone named "Pet Bed". There needs to be an option to name zones yourself. - Obstacles: When you review the history and see the pictures of obstacles, you only have the option of selecting No Obstacle, Temporary Obstacle, and I don't know. It would be nice to add options for things that are technically obstacles, but do not need to be avoided per se. Such as "Table Leg", "Chair Leg", "Bed Frame", etc.

UPDATE #2: It has now been several more months. I love it I love it I love it. One major issue for me was that it was a pain in the butt to carry the base around in a multilevel home. After rereading the instruction manual I discovered that I’m not supposed to do that, that you can just carry the machine around and place it. As long as it does not have to empty the bin or recharge, it does not necessarily have to begin and end on the charging base. Ok so this has made my life so much easier. I did have to update my maps several times to teach it not to expect the base when it was done, and it has since behaved perfectly well. (The first few times it wandered around for a long time and the program said “searching for base” and I felt sorry for it 🤣. I didn’t want to delete my map that had the base on it and start over because I had to teach it to stay off of a shaggy rug and that took a lot of tweaking). I also have stopped being stingy with use and have given in and am carrying it around and running it more often and sometimes going over areas twice to get all the cat litter, and my house stays so clean. That means I will have to change the filters and rollers more often but oh well! UPDATE: It has now been another month or so. I like the machine more and more and am changing the review to 5 stars. I have continued to tweak the programs I have set up on the app, and its performance improves. Since we have a cat, a major issue is the cat litter which she manages to drag all over. The machine sometimes will miss some litter in certain areas, and since we have dark floors it shows up brightly and drives me nuts. I can tell the robot to go over certain areas twice and that solves that problem. (Honestly the cleaners we hired would sometimes miss just as much if not more because the tiny specks get ground into the carpet). Another thing is that on our smooth wooden floors, the edge sweeping brush sometimes seems to scatter small particles around rather than pushing them into the rollers, and I have to have it go twice in places for that reason too. But with these tweaks it has been doing a really good job!! The suction is very good and the machine is surprisingly quiet. Also I am getting used to it and learning to leave it alone and not follow it around, so I’m much more relaxed about it. Another good thing—in the app the machine will tell you when it needs maintenance. There is a countdown to when I will need to change the filter and rollers, and I see that I will not need to change them nearly as often as I thought! The manual says filter every 2 month and rollers every 6 months, but according to my runtime it is going to be about double that, so I’ve got that going for me, which is nice 😉. ORIGINAL REVIEW: I do like this little machine. I hate and I mean HATE vacuuming and my husband has a bad neck and can’t vacuum. We had hired a cleaning service but it made the cat go crazy and just became much more stressful than it was worth. So we decided to get this realizing it would pay for itself (in the absence of the cleaning service) after a few months. You need to pick up all your things and allow it to make mapping runs when you first get started. The interface is an app on the iPad and it is very straightforward to operate, and you can make detailed programs and constantly tweak them based on the machine’s performance. The suction power and ability to pick stuff up—including cat hair and cat litter—is excellent. It is not very loud. The cat is not bothered by it, and EVERYTHING bothers her, so I am kind of amazed by that. I love that it goes back to its base and empties itself when its little bin is full. I am giving it 4 stars instead of 5 for a couple reasons. It is godawful expensive. I have learned that the replacement rollers and filters are kind of expensive and have to be changed very regularly. Also—and I admit a lot of this is my issue due to OCD—so far I feel like I have to babysit it and be aware of where it is and what it’s doing, which defeats some of the purpose of getting the machine to do the work in the first place. I am hoping this will improve in time since I have tweaked some of the programs and the machine is learning, and I just need to get used to it. Some of this is due to the fact that I have a multilevel home and have to carry the base around and then tell it to go, rather than just setting programs and ignoring it, which can’t be helped. It would be much better in a single level. All in all it’s really good, and has the potential to be great, but time will tell. We will see if the rollers and filters have to be changed as often as it says. Probably the filters do, because of my cat, but maybe the rollers can last a little longer.

Does not vacuum rooms well. Constantly gets lost. Maps are terrible. iRobot Support useless. I had high hopes for my 1st robot vacuum, $600 j7+ . I found online & studied; Owner’s Guide & “Complete Guide for Imprint Smart Maps and FAQs” I ran many mapping runs & cleaning cycles. Wasted a huge amount of time trying to get this to work as advertised. I searched for online Roomba forums for help & tips. Finally, I called the telephone support & spent ½ hr. With a support rep, who was no help at all. The j7 is very inefficient with time & battery life which would be OK if it actually got the job done. Clean the entire room & do not get stuck. It maps & cleans rooms at strange angle, rather than following the sensible layout of the room, which again is OK if it ended up cleaning the entire room. It would start in one area & w/o finishing, cross over to the opposite side of the room & start there & sometimes, eventually go back to the 1st area to finish. Often leaving a corner or different area unexplored/uncleaned. “Keep Out Zones” Unable to rotate the Red rectangle to align with a sensible barrier. I could make the square as small as 8” x 8” but always at a 45˚ angle so my ‘do not cross’ line was always a series of pointy diamond shapes. This resulted in the keep out area being larger than desired. It worked to stop the j7 from getting hung up but left too much floor uncleaned. I could rotate the map itself but the rectangles rotated along with the map. Support rep unable to help with this. Extremely frustrating! Room Divider lines: Often initially wrong. I can move the line & rotate the line but cannot make the line shorter! In one case, to correctly set the line correctly, between my tiled Entryway & my carpeted Family Room, the divider extended ½ way into the FR at an odd angle. If I was able to adjust the length of that line, I could make it correct. I could not & neither could the support rep. Maps are not correct re depiction of carpet vs. tile floor. This was strange. Often at transitions between rooms the map would have a bizarre carpet area encroaching onto tile & vice versa. Also the transition between rooms was often geographically incorrect. Instead of two rectangular rooms connecting via a doorway in between… Some odd angle would be introduced, which was just… Strange. If you have one floor and the robot can get everywhere, this might be a decent Robo vacuum. I have a single story home with a raised tile entryway. This results in three separate areas that the robot must treat as three different maps. The home base station is only in one of those areas. No matter how many times I tried, following the suggestion from the support rep, j7 continually failed to make a separate map of the entryway! It kept adding the entryway as a new area abutting the living room. This was technically true except the tile is raised 5–6 inches… An absolutely insurmountable barrier for the robot! The instructions and the support rep both state you do not need to move the base home station to other floors or other areas. Simply place the robot in the new area and then either press the button on the robot or press begin mapping or begin cleaning on the app. The robot will map/clean the new area and then since it will be unable to get home to the base station, it will stop, make a musical tone and wait for you to physically move it back to the base station. This absolutely does not happen! What happens is it will clean/map the new area and then the App says: “heading home" and j7 will wander around, bumping into everything, in a failed attempt to go home until it runs out of battery life. So, in summary, I wanted three Maps; 1) front house area, which has the home station, 2) raised tile entryway, no home station & 3) bedrooms and hallway (no home station) hallway is again blocked by the raised tile entryway. I would have no problem letting j7 clean the front house area and go back to the base station to empty the bin or recharge. But, then I needed to be able to physically move it to the raised entryway and tell it to clean and then when it was done to stop and let me move it back to the base station. Same thing with the back hallway/bedrooms. The j7 is incapable of doing this.
