I currently run my S6 on the first floor of our house. I ran the S4 through the same cleaning routine and it’s finishing about 10% faster and picking up a lot more hair and dander. The S4 will be running in my upstairs going forward since its 100% carpeted.
I do want to callout an issue I’ve seen others bringing up. The S4 was consistently having an error 5 - main brush blocked at the 14-15 min mark and then every 8 mins after. I emailed Roborock and they sent out an update that corrected the problem the next day.
There is a newer model of this item:

I wanted to love it so badly!!! BUT...

The long and short of it... It throws a ton of errors when sweeping on carpet!!---- Here's what happened ------We have had a Roborock S5 for several months and LOOOVE it!!! Never had a problem and always consistently swept our upstairs! When I realized Roborock just came out with an S4 I decided to buy one! It appeared it would have all the great features we loved about our S5 plus the benefit of having "room by room scheduled cleaning"! It didn't have the mop which was fine (we never used the mop feature of the S5 anyway)Well..... I excitedly unpacked and setup the S4 and sent him scooting around the house (I always love watching these robots map out our house in no time!) Soon after the S4 started sweeping my daughter's room (note: her room has low pile carpet) the S4 stopped with a "Main brush blocked" error! "Hmm..." I thought, "never had that before... well it must just be a random thing..." So I reset it... and then soon it was randomly going in circles.... Yea like crop circles in the middle of the open floor... {see the video} after it fumbled around doing circles it threw another error "Side brushed blocked" I reset this and... then soon "Vacuum is stuck please move to open area"....Long story short, it took the S4 45 minutes and endless amounts of random errors to sweep the same room the S5 has been sweeping error-free in 8 minutes.I believe this could be fixed with a firmware update, so I will gladly come back and update my review to reflect any positive improvements. Roborock... please... please!! please!!! update the firmware for the S4 to function like the S5!!!

This vacuum is awesome! At first, I was just on the verge of sending the vacuum back because of the issues that some of the other reviews have stated of the main brush getting stuck on carpet. I figured I'd take my chances and contact customer service over this issue to see if they could help. Even though it was a few days worth of emails back-and-forth with customer service the issue was resolved! Roborock pushed an update to my vacuum and I just went into the app and updated the firmware and I have had no issues with it getting stuck for the past few days. Before the update it would say the main brush was jammed every 15 or 20 feet, even it wasn't, and it was extremely inconvenient especially if you were away from home because you would have to keep hitting the clean button. Not sure why they would have launched this vacuum without this bug being completely fixed but atleast it was resolved. They said they would be pushing the update to all vacuums soon so I'm sure the issue will be completely be resolved for all customers.
The mapping feature is phenomenal! The initial vacuum of your house will take twice as long because it has to map out your house and will almost seem disoriented but after it saves your house's layout the vacuuming is much more efficient. It will go around the edges of each room and then do the perfect Z from side to side throughout. You can merge each rooms or unmerge rooms to create separate rooms for cleaning. The virtual no-go zones have also been great so you don't have to deal with magnetic tape. I have an area rug that has a fairly high pile and can't be vacuumed with these robots.
The battery life is great if you run it in standard but I usually run it on turbo so it only last about 70 minutes which still isn't bad. It does not complete my house in one clean but it recharges and picks up where it left off so it's no big deal at all. It will run over small toys and get stuck if the toy get under the vacuum just right but I'm sure every single vacuum on the market has the same issue.
I wouldn't call this a con but it's a bit annoying that you can't switch the meters to feet, or atleast I haven't found a way.
Overall it's a great vacuum and I would recommend.

Hasta ahora va bien, el sistema de mapeado es de lo mejor que he visto y navega increíblemente bien. Cabe mencionar que la aspiradora tiene un modulito encima que hace que sea muy alta, así que no pasará completa por debajo de ningún mueble que no esté alzado a menos de 10 cms. Es muy grande comparada con otras que he visto (alcanza casi 34 cms de diámetro). No es recomendable para espacios muy pequeños, no pasará en espacios angostos. Este modelo no trapea. Adquiérela si buscas un robot que solamente aspire, haga mapeado y tenga conexión WiFi (si no te importa perder horas esperando a que se conecte), eso lo hace muy bien. Si puedes vivir sin el mapeo entonces hay muchas otras opciones más económicas.
