Carpet or hard floors? I have a roborock S4 pure and it is fantastic on my hard floors for cat hair. for carpet, I have a shark navigator lift away and it does a really good job at get pet hair out of carpet and off the couch.

I’ve been running a Roborock S4 close to five years. Has been great with basic maintenance. Only part I’ve had to change out is the battery. Cost $50.

Have also owned roborocks since the S4. The only big downside is IF something does go wrong past their 1 year warranty you’re completely out of luck. Their in house repairs are prohibitively expensive (costs almost as much as a new vacuum). My dock broke for my S8 Pro Ultra at the 13 month mark and they advised me to buy a second hand one off eBay because they don’t repair docks or sell dock replacements. Their service in the US is absolutely terrible. I ended up getting a new dock off of eBay for way too much money and I’m hoping it lasts more than a year.

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

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.

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

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.

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?

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.
