iRobot Roomba i7 (7150) Robot Vacuum- Wi-Fi Connected, Smart Mapping, Works with Alexa, Ideal for Pet Hair, Works with Clean Base

We already own one roomba (roomba 860, bought in 2016). WE use the old one 2 to 4 times a weeks and still runs great after 4 years (to my surprise we didn't have to replace the battery yet).However I really wanted to get a new "smarter" roomba to run on the first floor and keep the old roomba on the ground floor to clean rooms in parallel. The roomba I7 has been a game changer.1) NAVIGATION: the I7 is so much smarter in navigation compared to the old 860. The old 860 was using a random pattern that was very unefficient and very time consuming. The i7 is methodical with parallel strokes and finishing by vacuuming the room edges. It gives me reason to believe all room as been vacuumed and it is a lot faster so can get more job (more sqft) done in the same amount of time. If it runs out of battery during a cleaning it will go back to the dock station, recharge, and resume where he left off: altough we don't really use this feature (we typically plan cleaning runs that are well within a battery charge) it is a nice one.2) SMART MAPS and APP: the smart map is so useful. No need to baby sit the roomba by putting lighthouse (the light fences) or move it room to room manually. Now with the app I just choose which room I want clean and the roomba undock, goes to the room(s), clean only that room(s) and come back to charge once finished. Making a schedule on the app is very fast and easy. Remote start is also a nice thing (example we checked in the morning that kids have not left stuff in their room and then we can start the roomba after leaving so he does his job undisturbed).We didn't buy the self cleaning station. The price premium was excessive and we didn't think it was necessary. We always clean the roomba after each run (we have a normal vacuum that we use to vacuum the dust bin and the rollers). Said that it is probably a nice feature for families with different habits / needs.The two cons that I have is thata) the dust bin is smaller than the old roomba. Said that it has never been an issue for us. We run the roombas in short task (30 minutes cleaning in average) and we clean it up after each run, so the risk of overfilling is very low for us. Said that it coud be a minus with familieis with different habits.b) it will NOT run in the dark, it needs light to operate (otherwise the camera cannot detect the rooms). Again this is not an issue for us as we always run it during daytime when we are home or in the office.Based on this roomba i7 is a 5 stars for us and we stronlgy recommend it.

I was really excited to get a Roomba for my new apartment and it is something I've wanted to purchase for some time now.I decided to spend a bit extra to get a nicer model with a few key functions like the ability to control it from an application and schedule by room. I've used this feature a few times and it's amazing - being able to just clean my kitchen while I'm lounging in the living room, or clean my bedroom while I'm making dinner - It's awesome!However... This Roomba is just not what I expected, especially for the price, wow.First of all, this thing runs in random circles around my spaces - it swears that it follows some planned path but it runs into everything most of the time and hasn't learned very much apparently.Second, and my biggest complaint, is that it gets stuck, on EVERYTHING. Rugs, Chairs, Barstools... the list goes on. Not only that, but it will make an aggressive effort to climb over or on something that it shouldn't and gets itself stuck then weakly spins it wheels before complaining that it needs help.I'm frustrated and disappointed that even though I just arrived at work, I have already received a notification that its somehow stuck. I have walked around with this thing 5+ times to see where the problem areas are and I just can't win.I've had to block off multiple sections of my place because it gets stuck on the tiniest of chair legs, and even sends a cliff alert only to be found resting on the edge of a rug????????? That's ridiculous.For nearly $600, I wish I had purchased a Dyson hand held that would do a quick and thorough job. - like wow the regret is real with this one.This thing spends more time getting errors and "stuck" messages than it does actually cleaning my apartment. It also leaves bits of debris everywhere - including bits of paper and such that you think it wouldn't have any issue at all picking up.Really disappointed... We have a really long way to go with these robot vacuums, they're just not very good yet.Ps. The "Rate Features" function is useless. Sure, it has good battery life and works with Alexa, but it can barely do a full run of my apartment without errors and getting stuck or missing sections.Update:I have never had such a frustrating and disappointing experience from a piece of technology this expensive. These are so unbelievably unintelligent it boggles my mind how they’re advertised. If you enjoy spending the amount of time it would take to vacuum your place cleaning up every little thing on the groundI have never regretted buying something more than this. I would have been better of spending the money on a hand held Dyson and spend 20m vacuuming vs the 1h 30m this thing takes running into walls, getting stuck on the smallest things and going back over things 4-5xThere are many things that have benefited from automation, and vacuuming is NOT one of them.
