iRobot - 650

"I seriously love iRobot hardware vacuum performance as in the amount of dirt they pick up"

"They're great at picking up litter and combing embedded pet hair out of carpet."

"Never had any issue with roomba when it come to vacuuming up dog food or anything that size."

"I also don't think the Roomba 600 series need cloud features."

"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."

"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."

"Honestly emptying the bin yourself after it’s done takes 30 seconds :)"

"These 2 both still work. ... 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."

"It has had two battery replacements in its life, and has had a replacement main board once, which added the schedule feature. ... considering you can change all of the parts with a screwdriver and a bit of basic knowledge (how to plug/unplug things)"

"$20"

"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."

"pretty common, cheap"

"my roomba 600 has outlasted all the fancy lidar ones my friends have bought. ... I've had it for almost a decade"

"We have had an iRobot Roomba for 17 years. ... This Roomba, with replacements when things wear out, has outlived most other appliances we have."

"Older roombas are simple, reliable, durable, effective, and cheap. ... 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."
