iRobot - 650

If it's just one room, get one of the old random bounce around Roombas with the bristle roller. 500 or 600 series. They're great at picking up litter and combing embedded pet hair out of carpet. I have a 692 I keep just for that. They're also super cheap because everyone wants the self-emptying models now. I see the older ones pretty often at thrift stores and Facebook Marketplace for under $30.

Older roombas are simple, reliable, durable, effective, and cheap. But they don't have smart navigation or mapping where you can ask them to clean specific areas. If you want navigation they become less cheap and less durable. I have a 10yo 600 series roomba and a new Roborock Q5. Q5 is great but I'm skeptical that it's going to last as long.

I’ve had many roombas from the 650, i7, S9x3 (they sent me 3 replacements), and a braava jet 240. They work good for awhile, but the crappy software updates, constant errors and resets broke me. I seriously love iRobot hardware vacuum performance as in the amount of dirt they pick up, but the software is absolute garbage and a vacuum is completely useless if it can’t navigate correctly. I still have my first 650 bouncing around in my basement and the i7 has been moved to garage duty. The S9 ended up in pieces. My main two robot vacuums are roborocks and I love their navigation. I wish I could take the navigation from a Roborock and put it into a roomba.

I bought a Roomba that can mop and vacuum (pricey models are great). I bought a bunch of replacement rags/mops on Temu for a few euros, and exchange them every now and then. All you have to do besides that is fill its water tank with clean water and floor soap. I also went on my Roomba's App, drew out a map of my house, and set a cleaning schedule for every single day on setting 'deep clean'. And he keeps the floors like 98% spotless, while we have 2 long-haired dogs and 1 short hair cat. We still vacuum and mop ourselves like once a week or so. But if need be we could easily skip that. The difference has been amazing. Googly eyes are optional. ;) Why do it yourself if a robot can do it for you?

See if you can find an older Roomba at a thrift store. I thrifted my Roomba 650 for $25. Replaced a couple of simple parts. No app, does its job

I have a Roomba 564 Pet I bought when my son was 6 months old. He's now 14 and the Roomba would be still doing the job if this little bastard had not screwed the elly plaque's screwheads. I bought a new battery I cannot replace because of that (I'll Dremel them out after the Spring clean out). So it was working since 2011, August. The other Roomba, a 600 something bought on discount in a clearance sale when my son was 6 or 7, is still going strong. I wonder how the Dreame L50 Pro Ultra is going to perform. It is my Mother's Day present, but we're not done with the Spring-clean so it just worked in the living-room.

I'd recommend an older roomba model as well, 500 or 600 series. They're very easy to take care of and repair, clean really well, are simple, and last. I have one of those cheap ionvac models you've probably seen. It's better than I expected, but an older roomba is way better still.

My neighbor threw away a perfectly good 960 and I've been using it for three years, 3 times a week on 750 sq ft. (It had hair wrapped around the brushes, once I cleaned it out it ran just fine). It's easy to take apart and clean. I haven't had to change the tires yet, they are still going strong. I'm still on the original battery as well. The bin latch to the filter breaks easily (I've gone through 2 and now I just leave it broken). I do have to clean hair out of the brush ends often but that's easy enough to do. It's hasn't broken down on me yet. On my old 650, I replaced the side brush motor and tires which would be the same process on this model. I'm very happy with it especially since it was free.

We have had an iRobot Roomba for 17 years. We initially bought the 535, it’s been upgraded with the new bin (aero vac 2) and running gear from the later 600 series It has had two battery replacements in its life, and has had a replacement main board once, which added the schedule feature. It cleans better than the 780 models relatives have. This Roomba, with replacements when things wear out, has outlived most other appliances we have. You can still buy the 600 series which is based on the same platform, and if ours ever became unrepairable, we would buy one. Heck, considering you can change all of the parts with a screwdriver and a bit of basic knowledge (how to plug/unplug things), a second hand one would be fine.

I beta tested a shark and an update randomly disconnected it from the app and it would not connect again and their beta test support was useless in getting it reconnected. Tried blaming it on my mesh system. I went as far as to get a stand alone router/wifi from my internet provider and hook that up and try to connect it that way and still the same thing. The app would freeze once it found the robot, even after updates. I really liked how the vacuum worked up until then but I’d never buy one after that. My 600 series Roomba and i3 Roomba have never had Wi-Fi issues on any of our network iterations over the years. I ended up buying a Eufy over Black Friday.
