650

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.

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

So many questions. Namely, how the hell does a company that was once at the top of its market let itself go to seed like this? And secondly, why on earth what I need my fucking vacuum cleaner to be connected to the cloud? My iRobot 650 that I bought used over a decade ago is still going strong.

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.

The older Roombas could be set to clean once per day at a specified time, so you could have 7 scheduled cleanings. There are buttons to set the clock and then a cleaning time for each day of the week. I still have 2 of them, one is a 650 and the other is a 500 something. I don't think they make them anymore, but I am sure you could find one. These 2 both still work. I don't have an app for them, but I have a 3 foot dowel rod I use to push the start button, If you have connection problems or simply don't want to connect to the internet, the solution is to not connect. Just push the start button. The advantage of the Roomba brand is that you can get replacement parts easily and they run forever. There's lots of info on how to repair them. Don't know if the other brands have that knowledge base yet.

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’ve never understood this. I have an old Roomba 630 that “blindly bounces around” and it’s fine. Bought almost a decade ago and I still use it every day. Easy to get spare parts on eBay. I dread the day that it dies and I need to buy a cloud-connected model. How much better are these newer mapping / cloud-connected ones? Do they really add that much value?

I have one basic Roomba that moves around randomly and another that supposedly maps the space. The cheaper, random movement robot is vastly superior in all ways.

No robot vacuum is going to do well with stones and if there’s snow, it’s going to get wet when it melts. You’d probably want to get something industrial quality, like Makita or Pudu, but those are HUGE and probably will be too big for 600 sqft. If you meant pebbles when you said stones, you might have a better chance with one of the older iRobot Roombas (500-600/Professional series) with the high capacity sweeper bin. They are cheaper on eBay now and don’t have as many problems as the Dirt Dogs. I don’t think any household robot is going to clean up stones at all. And even if they somehow do, it’s going to get clogged in the auto emptying dock.

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.
