Stops randomly in the middle of rooms with "drop-off detected" errors. Moving it around and cleaning the sensors does nothing, support is wildly unresponsive/unhelpful. Similar issues with it complaining about bin being full when it's not. There is no way to disable or override these erroneous errors.

Overall I enjoy it. Who doesn't like not having to vacuum every day? But the base station requires me to push the bag down every day, or every two days because it will say bag missing. The maps often get messed up, or it won't go all the way to the wall and leave around the walls un vacuumed.

[This review was collected as part of a promotion.] I have never tried any product like this before. I've only used normal old school vacuums, nothing fancy about them. I was intimidated at first, to try the product but surprisingly set up was extremely easy. Directions were easy to follow. I have a very heavy shedding dog and normally vacuum my rugs at least 5 times a week. I got this charged and it started going. I was so impressed with how it mapped out my house, told me the areas that had hazards, and then docked itself right back on it's charger all by itself. I set it to start the next morning at 11:30. The bin was full so I took it out and emptied it. I was amazed with how much hair and debris it picked up. It cleans my whole downstairs (5 rooms) with a very heavily shedding dog in aabout 2 hours and it handles the hair! I only empty it after the 2 hours. I have mostly hardwood floors with area rugs and I'd always get 'tumbleweeds' of dog hair blowing across it or getting caught in corners. Since I got this, I haven't had 'tumbleweeds'! And it cleans my rugs so well that I only bring out the big heavy vacuum 2 times a week tops. However after a few days, it can't seem to dock itself and if it does get itself back on the charger, it isn't aligned. I have to go move it slowly until I see the charging light come on. If I had paid for the product, I'd be unsatisfied with this flaw and I'd probably tell people not to buy it. But I am impressed with all the other aspects. Without that flaw, I would definitely recommend this to family and friends. With that flaw, I want to be honest with them especially for the cost of the product. To me, totally worth it! It's not a big deal to me to twitch it's position and I'm more happy with all of the other functions of this than I am dissatisfied with the one main flaw I've encountered. I would recommend this product regardless, but like I said, I'd give a heads up on that flaw especially for how much these run.

Our j7+ is an upgrade from our old Roomba we bought well over 10 years ago. While the old one worked very well, this new model is vastly improved. It is so much more powerful we noticed a difference right away. The mapping function is truly awesome, it really doesn't stop until it has covered the whole house and the rollers don't get clogged with our cats hair like the old ones did. And the self-emptying feature works extremely well and is a great convenience. Can't say enough about it. The phone app works well but could stand to be a little more intuitive.

STILL TERRIBLE. We've had this vacuum for just about a year now. Started experiencing issues with it about a month in, contacted customer care and they would not refund us. All they did was send us brush replacements and told me that was the issue. No, that did not solve the issues. Constantly having to unplug it and factory reset to get it to work again. I posted a review on this site about two months ago and Irobot reached out to me and offered to send us a brand new vacuum which I thought was nice. We get the new vacuum, get all set up and less than a week later we are having the same exact issues as we were having with the old vacuum. This vacuum is garbage. not worth $800

Very disappointed. Spent a ton of money on this thing in January only for it to completely stop working already. I have followed all the steps and have done everything possible to get rid of "Error 26" and still nothing. Now if I want to fix an already very expensive vacuum, I have to spend MORE money to replace the head module if I ever want it to work again. I guess the old "You get what you pay for" saying doesn't include this pricey machine.

[This review was collected as part of a promotion.] This has been the best vacuum upgrade yet! This has been a game changer when it comes to cleaning and any Roomba upgrade. One of the best features is the napping for areas in the house. Especially right now with the holidays you can tell your Roomba not to go near the Christmas tree or within a certain range of it so it doesn't bump into any decorations. We use the Roomba almost every night once the day is done, and especially in the kitchen. We will tell the Roomba to come out, clean the kitchen and go back. It is definitely one of the most powerful Roomba that we have yet had in our house. The self emptying function is one of the best qualities of the Roomba j9. Although the self emptying function is quite loud it is worth it in the end. You can let the Roomba j9 clean the entire house without having to empty the basket each time it is full. You can leave the house and it can finish the entire cleaning job. I would highly recommend the Roomba j9 self emptying vacuum!

Bought a J7. Was working fine for 2 months, and all of a sudden, it was useless with error 26. Recieved a replacement cleaning head module, it worked twice, and now, getting error 30. Waiting for another replacement cleaning head module. Wish I new I'd be having problems before wasting money on this product.

[This review was collected as part of a promotion.] The J9 self emptying robot vacuum is amazing. Vacuums on a schedule that you choose. Does very well. You can also choose a setting like lightly vacuum or deep vacuum. Very convenient! A big help in my household.

I have a full house with 5 people living in it the roomba helps me soo much less work for me to do. It avoided everything iRobot had said on their website hasn't ate up any wires. I have been owning my roomba for a month and I am in love! I highly recommend. Easy set up although the mapping part had me a bit confused but I figured it out.
