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

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

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
