"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)"
"iRobot is cool cus they seem to like Makers tinkering with their products sonthey make them very easy to fix. ... You can swap batteries out, motors, wheels... anything."

"Self emptying is the best upgrade ... haaaated emptying that thing constantly"
"I upgraded to a roomba with the self emptying thing and I love it."
"Now we have two good ones (iRobot) with the bin that they self empty into when they get full. ... Before we got the one with the bins, it would get full and need emptying before it finished a whole cycle. Now it goes and empties itself and then goes back to cleaning."

"Granted the Roborock S50 is from a different era, but what the actual heck - clean/dirty water tank, washes mop with hot water, dries it, auto dispensers detergent, has a swinging mop, lifts the side brush during mopping (!), is dead silent when mopping only. My floor is cleaner than it’s ever been.."
"their tech features just aren't as advanced as some of the newer brands ... If you want something with... mopping, etc, you probably want a Roborock"

"That makes them clench down, and therefore makes them hard to push and pull on that type of carpet. ... it was very difficult to push on that carpet until I adjusted it."
"Only if you have a few, small low pile rugs. The turbo head isn meant for carpeting."
"All 3 are excellent options though as long as you don’t plan on having wall to wall carpets or more rugs/thicker pile rugs over the next 20 years or so."

I bought a Roborock S4 back in 2020 and it still works great. I maintained it regularly but now Roborock stopped selling the main brush replacements so I need to try 3rd party. If I'd known ahead of time, I could've bought in bulk but I guess 5 years is a long time for a robot vacuum anyway
r/RobotVacuums • Robot vacuum that will last ->S4 running daily for 5 years and Max running daily for a year.
r/BuyItForLife • The Best Robot Vacuum that Lasts? ->Also have an s8 with vibrarise. I’ve read that the super “in” dual rotating mops aren’t proven to be better than vibrarise. What I will say is that I think mops on robot vacuums are still a “maintainer/extender” feature than a true mop up stains type of feature. If you manually mop, the s8 will make it so you have to do it less often. It’s not a replacement for that first initial manual mop. Besides that, I’ve enjoyed the s8 as it was an upgrade from my original s4. Obstacle avoidance is pretty good, although, I’m just used to tidying up before running it now a days.
r/Roborock • Is the VibraRise System of the S8 worth it? ->I have a 9 month old so everything you said applies to me… I will say I haven’t checked on the ramp thing but the s8+ I bought last year works very well. It goes over the mats. The reason I bought it was because I wanted better than obstacle avoidance. I was coming from an S4 (not max) which had none. This does a good job, is self empty and does mop too. The mop is a vibrating mop bit the spin type of a revo. This doesn’t bother me as robot mopping still isn’t great no matter what you get, until you’re shelling out $1500+. Even then, I don’t think mopping tech has “matured yet”. I ultimately would just recommend a robot vacuum that has good obstacle avoidance as you just don’t want it to get stuck places since you’re spending time with your kiddo and not worrying about cleaning/picking up as much
r/Roborock • Baby gates and play mats ->I just replaced a Roborock S4 which I have been using since 2019, with a Roborock Qrevo Curvx. Man, what an upgrade! The S4 was still running fine, but I wanted something with a mopping function. Ran it yesterday, and the new Curvx did an amazing job. I was really impressed by the amount of new features which can be found in these robo Vacuums now. I believe the added cost for the high end models are worth it… as they have functions that lower cost models will not.
r/RobotVacuums • robot vacuum black friday cyber monday deals to check out? ->I need a good one for my mix of hardwood and carpets that won't tangle with husky hair Self empty and mopping capabilities. Good mapping tech to avoid kids toys. Currently have a roborock S4 which does ok but constantly tangles hair, doesn't fill dust bin all the way, leaves clumps on floor. Any recommendations?
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->I have two Husky s and been reading about the qrevo edge s5a, although the dream l40 is still available, I'm leaning towards the roborock since I already have one and been pretty happy with it.
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->I’ve had my roborock s4 max for years and I love the thing.
r/homeassistant • What's the best robot vacuum and mop IYO? Is it really worth its expensive price tag you paid? ->I also have two S4s. I don't run them too frequently but yeah they're about the same age and I haven't had issues with either.
r/BuyItForLife • The Best Robot Vacuum that Lasts? ->My S4 is thankfully still going fine (except it 'mystically' stopped cross-hatching), however i did want something with some basic obstacle avoidance and having replaced the original use-case for the S4 with something that had an auto empty dock, i really wanted that function too. I get your waste to have a mop function and not use it, and i also understand the getting used to manually emptying every day, but honestly, the ease and improvement in suction when the bin is frequently (and automatically) emptied, is worth it. For the mop, manufacturers are shoving one on there whether it's any good or not, it's a check box for the showroom brochure, i would just ignore the fact it has one. Now, i replaced my S4 with an Q10 S5+ - it's the auto-dock'd version (the +) and whilst it has the fancier mop compared to the otherwise identical Q10 X5+, for some reason, the S5+ is frequently available for $299 on sale. Finally, bear in mind our S4 has a great/large dust bin capacity, that's not typically the case with newer models, they're more or less designed to have an auto empty dock to compensate. To go back to my point of getting max performance during the vacuum run, i have mine empty every 15 minutes, keeps the bin and the filter more clear, as the more full the bin, the lower the suction will be. I tried various replacements for the S4 for carpet-only performance, and the Q10 was the best.
r/Roborock • S4 Died After 4 Years, Looking for a no-mop replacement, what to buy? ->upvoting this. Love my roborock, just bought a second. My S4 Max has been going strong for like 3-4 years now, hell, maybe longer.
r/homeassistant • Robot vacuum recommendation ->Really? I have 2 GSDs and my Roborock is a game changer.
r/CleaningTips • Are the robot vacuums worth it? ->I have an s4 and a s8 pro ultra
r/CleaningTips • Are the robot vacuums worth it? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
