S4A Edge is what I have. I have been very happy with it. You do have to stay on top of the filter in the vacuum and the bag in the base. I have it vacuum a few of my rooms each day and vac and mop with the lowest solution level all the rooms once a week.

All of my family have Roborock. The Basic S4. 5 years and still running with no issues. Like anything, you do the basic maintenance, and they will work. I am shopping for the Qrevo next. Hopefully I get a good price on Black Friday.

For carpet only, I would use a cheap Roborock S4. You can find some for like under a $100.

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 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

S4 running daily for 5 years and Max running daily for a year.

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.
