Excellent (refurbished)
I got a refurbished version of the i4+. It's a great little vacuum. It runs more quietly than our Dyson V6 stick vacuum. It is able to make the transition from hardwood floors to rugs by lifting itself up slightly. It has a bit of trouble with thick rugs on hardwood floor, so it's better to pick those up, but it will usually end up going around. It's great at sensing obstacles, and can even navigate under the dining room table and chairs, though it does take a while. Not having to empty the dust compartment every time is amazing as well. In terms of suction, it isn't quite as powerful as the Dyson, but since we can have it run every day with no effort on our part, it doesn't really matter if it leaves a few dust particles here and there; they'll get picked up the next time. The app is also pretty good. It lets you select which rooms to clean (after you label the map it creates), and has a Send Home function, which is great if you want to end the cycle early. After a month of use, I would definitely buy it again. This item was refurbished. It came in good packaging, though not the original. There were no signs of wear or damage, and everything worked great out of the box. The manual was very short and simple, but I didn't need any more than that. ... show more

No manuals, no QR code for activation, smart maps doesn’t work, won’t climb flat rugs. Useless.
This is an awful vacuum. Believe the bad reviews. There’s a reason eBay and Amazon are flooded with refurbished i4+ Roombas. It was useless for me. They don’t include a hard manual of any kind and the setup is not obvious. They claimed a quick start guide and a QR code were included. The QR code was included but wasn’t recognized. No quick start guide. No one thought to provide a manual for the self emptying feature and the best manual they have, applies to the model without self emptying. Because there was no “this is what is in the box” guide, I thought it was missing a brush and broke into a set of spare parts I bought along with it. That’s $20 wasted. If I had a manual, I could have seen the lopsided design was intentional. But aside from all this, it won’t climb a flat area rug a $110 robot handled just fine. It gets stuck everywhere and looks like it’s confused. But to top it off, the smart map feature is basically a hoax. I ran the mapping feature and then looked for my created map but could not label rooms and it didn’t appear in the smart map section of the app. When I click the smart map link in the the app, it just crashes every single time. I called technical support and the tech experienced the same thing. My $110 Yeedi special cheap model beats this one by a mile. Do not buy this. I will not buy a Roomba again. They should destroy these when they are returned rather than try to find suckers like me who think they’re getting a deal. ... show more

Highly recommend
This is doing a fine job. Set-up via the app is easy. The Roomba will follow your command and map your floors -- room by room. It even has a feature that prevents it from falling down the stairs. And it works with Alexa. It does its job. It cleans well. I recommend you occasionally flip it over and inspect the bottom components, especially, after you first place it in service. We have girls on the second floor and the Roomba collected hair that we didn't realize was under the bed and in the corners. After first use, it was necessary to remove hair from the rollers and spinning brush. Nothing was wrong, we just had a lot of "invisible" hair. I highly recommend inspecting the underside after the first few uses. I like the scheduling feature, and the ability to mark areas on the map you may want to avoid. This is our second Roomba and their customer service was outstanding. After three years with our older model, we experienced a technical issue and customer support helped solve the problem. I'd absolutely buy another. Remember to inspect the bottom; especially, if you have long haired persons or pets. ... show more

Missing Instruction Books & QR code for registering

Great Price, does the job
This is a good price for this self emptying Roomba. It was a refurbished in excellent condition. I’ve had it for a couple months and it works great. I don’t have any problems with it, and it basically looked new coming out of the box. It maps out my rooms and I can decide where it’s going to clean by using the app. They can claim the two rooms that I have mapped out or just one room or even an area if I choose that as a mapped spot. I have always had great results from my Roombas. ... show more

A real back saver
I bought this IRobot based on the Consumer Reports recommendation. It has worked very well. My wife and I are over 80 years old and this vacuum saves a lot of strain on our backs. There was a second reason for purchasing this particular unit. This one was the second highest rated and under $300 while the top rated was over $1500. I will admit that it is not the best for a house with stairs since it doesn't have a sensor for that. Our house is all on one floor and no carpet so it works GREAT. ... show more

Sucks, but not in the way a vacuum should.
I’ve had this Roomba for a couple years. It does such a bad job I don’t think it has finished a complete job more than 5 times. It always fails for no reason or ends up stuck in the same place (a very slightly uneven floor near a corner) I have yet to buy replacement bags after the first set I purchased with the machine. Which means it has barely done any cleaning. What it does do is make a lot of noises. I wish I hadn’t wasted my money, ... show more

Tried this self emptying iRobot vacuum to assist in keeping up between dyson vacuum days once a week (as I have 1 golden retriever). The price seemed right and claimed to work for animal hair. The first use I noticed it would very loudly empty and then leave trails of knotted hair piles. After 3rd attempt the vacuum would not finish the job and even go to the base. I tried getting the app and then it really went downhill. The alerts would start after only 5 passes across reasonable size room, first you clean the rollers, restart, then you empty the self emptying bin (that was empty), then the roller again…. I gave up. Dispute my chronic pain i would rather vacuum by hand twice a week than this hassle every other day. You should not have to babysit the automatic vacuum. Aside from the dog hair battles the vacuum makes wonderful lines like your carpet was vacuumed, but not a whole lot else. My weekly pass with my Dyson confirmed that there is very little cleaning power despite being run 3 times the week prior. Disappointed as I was very hopeful. ... show more
