Okay, so this thing is actually a life changer for a couple reasons.1) We have a labrador. Even with consistent brushing, her hair is always EVERYWHERE and coagulates in corners on the floor and under our couch (which this robot can scoot under).2) I now am horrified at the realization of how much crap and nastiness accumulates in the floor of a house within 24hrs. I'll never be the same.The pictures of the dust bin below are from single runs 24hrs apart in our small, carpeted bedroom. EVERY, SINGLE, DAY, this little robot picks up an ENTIRE bin's worth of dust and hair from our bedroom, as well as a full bin from our kitchen and living room which is hardwood. It's actually insane - it's not like we live in a palatial mansion, they're normal sized rooms - and I'll never look at the floors of my house the same ever again.As far as the robot itself (which I've affectionately named Ding Dong), it's adorable and does everything it needs to do efficiently and effectively. It's a little louder than I expected it to be, especially when it's running over carpet or when I have the vacuum power turned all the way up, but since I'm running this during the day, it's a complete non-issue. This thing could sound like a jet engine in my living room and I would still give it 5 stars because of how well it cleans.The app is also intuitive and easy to use. I don't like that it requires wifi to work because I'm a privacy fiend, so I set it up with an old cellphone on a network that's only used by roborock and other smart home devices. The beta mapping feature works wonderfully; I have my rooms setup and can quickly tell Ding Dong which rooms I want her to clean. The app also has a maintenance category which will keep you informed on when routine tasks should be performed, such as cleaning the brush or replacing a filter, as well as an instruction manual built in to help you through your first days of usage without needing to flip through a booklet. Other appliance app developers should be looking at this one and taking notes.I should also mention that we got almost $200 off the list price because of the Amazon sale and another coupon I found online, so for me, the price point was great. If I had needed to pay $429 or $499 (current list price), I don't know that this would be five star. I do feel that $500 is a bit overpriced, especially considering the discontinuation of the S4, which is what I was originally intending to purchase. Having a more expensive model (eg, the Max) is all well and good, but the price is a bit more problematic when the original model is no longer available (ESPECIALLY when there is a *visciously competitive* market for used or "open box" S4s on resale sites like ebay). I also wish Roborock would change their website to reflect that the S4 is no longer sold; currently, the page for the original S4 links to this listing here for the Max. I find that misleading.So, overall, since I was able to buy the S4 Max at a steep discount, I'm over the moon with this purchase. Ding Dong is a huge time saver, and within the span of a week, she has made a noticable improvement to the air quality in our house... So much so that I'm starting to form a belief that access to a robot vacuum should be a universal right. If you've got the extra cash and have been holding off pulling the trigger on a robot vacuum, let me be the first to suggest that you treat yourself. I really don't think you'll regret it; even at MSRP of $500.

I've only had my Roborock S4 for short time, but I'm very impressed. I'm the veteran of 3 previous robo vacs and this is the first one that actually does what it's product description advertises. I'm sick of vacs that randomly clean, don't respect boundariesand don't clean very well.1. It does very well near stairwells. I have an open stairwell on my main floor going to the lower level and 2 previous vacs have made s swan dive down the stairs or through the opening to the floor below - one just ignored the boundary strips and went right over. This guy went up to the stair opening, paused, and backed off - every time I've run it and I've kept a close eye on it when it gets near the stairs. Its cliff sensors really work. I've now drawn walls and a no-go zone as added insurance but I feel pretty good about it not making the Thelma and Louise dive the previous 2 did.2. It's a quality vac. It just feels more sturdy and the brushes are rubber and don't seem to tangle as much. Also, you can wash out the filter - this is a real bonus cause those suckers cost a bundle. They suggest that you do clean it and rinse it between uses.3. I love the mapping. Once you run it for the first time, it creates a map in the Roborock app and you can then create no-go zones or virtual walls. You can also send it to just one room or area to clean. I just tried that out and had it go to the furthest room from it's base and it made beeline right to the room, cleaned and returned to the dock.4 It is efficient and I love, love, love the lines it leaves in my carpeted spare room - something I never achieve when I vacuum.5. I previously ordered a Roborock 5 last year but returned it when I couldn't hook it up to the internet - but that was my error. I didn't realize my phone wouldn't automatically pick out the right band - this only connects to 2.4gh, not 5. It's easy to connect and the app is easy to understand. Also, there are a couple really good tutorials on YouTube to show you how to use the app features that I found helpfulI figured out that I had to change the wifi connection to 2.4 on my phone with the Amarey I ordered to replace the Roborock I returned - Amarey is one of the vacs that took a swan dive and now only runs in circles or one corner of the room. Anyway, I got so frustrated with that piece of crap I started looking again and saw they had redesigned the Roborock 4 to work without mopping (I didn't want mopping) at a much cheaper price than the 5 or 6 models. Actually, I'm glad it turned out that way because I love this guy so much. It is exactly what I envisioned when I found I wanted a robot vac.One thing - make sure to clear your floors and move chairs in your kitchen or dining room the first time you run the vac while it's making it's initial map. That way it gets a clear vision of your floor plan. You won't have to do it every time afterwards. Also, I have a dark bathroom with no windows and it mapped it but didn't clean it the first time I ran it so I turned on the light the next time and it went right in and has gone in since.If you are looking for a good mid priced robot vac - check this guy out.
