Breathtaking Suction

Powerful HyperForce suction creates up to 2000Pa of suction power, pulling dirt and pet hair off wooden floors as easily as it dredges it up out of carpets. Ideal for picking up after messy kids and hairy pets.

Keeps Carpets Bright

Automatic Carpet Boost automatically ramps suction power to maximum when a carpet is detected, providing a more thorough vacuum. The floating main brush lifts up to agitate the fibers of the carpet itself, smashing out trapped dust to leave carpets bright and clean.

Long-Lasting Cleaning

One charge of its battery gives up to 180 minutes, or up to 300sqm, of cleaning, with all debris securely captured in a large 460ml dustbin.

The control is yours

Using the Roborock app, drop up to 10 No-Go Zones and 10 Invisible Wall on every level without a single hardware add-on. Use this to keep S4 Max away from precious items, troublesome furniture and more. The control is yours.

Problem Area Cleaning

When you need to clean a specific area not a whole room, draw Zone around it, set the suction power you want, and send S4 Max on its way. You can create up to 5 zones at once and every zone can be cleaned up to 3 times to really tackle tough dirt.

Automatic Top-Up Charging

Clean larger spaces automatically. If the battery runs low, the robot will go back to recharge, then continue where it left off.

    First time robovac user. Roborock S4 max worth the money!
    5 Stars
    First time robovac user. Roborock S4 max worth the money!
    Purchased a “used like new” item. Didn’t look used at all and according to the order it came from Roborock. The new one had a $70 coupon but this one still came out $80 cheaper than that one.I was VERY impatient. I only waited until it charged about two hours, to 65%. It got to wall mapping the last two rooms (bottom center and bottom right) before it had to go back for a recharge. Well a couple hours later I was impatient again and didn’t want to wait for a full recharge (78%), so I hit the “clean” button in the app and Piglet, yes that’s her name, announced “resuming cleaning”. It finished and again returned to the dock at which point it saved the final map in the app (make sure you turn on map saving!)I had to empty the bin three times in the process, about a third of the way through each time. Would I like a self empty unit? Yes. Was I willing to spend that much to get a self empty unit? Heck no. I was already skeptical and I figured I have to empty my Shark upright every time I vacuum so what’s the big deal?I named my rooms, set up a couple virtual walls and no-go zones. Pretty easy even on the small phone screen for someone with pudgy fingers.I’m pleasantly surprised. I didn’t expect the carpet to look as decent as it did when Piglet finished. It got under dressers. Vacuuming under the beds without moving them! Even squeezed beside the toilets. Make sure stuff is out of hiding places high enough for the bot to get under and it will probably figure it out!Oh and the thresholds. The apartment has about 3/4 thresholds if not closer to an inch - I hate them but I digress. The master bath it just went up and over easy peezy lemon squeezy! The main bath it went up and got stuck. I thought uh oh I’ll have to keep an eye on Piglet when she’s doing that floor. Nope - she backed up a little, turned to more of an angle, and up she went.Of course your results may vary. I was tempted to use the iRobot j7+, considering the warranty and maintenance parts and all - but dang after you cancel the membership it won’t work anymore?! Heck no. Especially being a first timer for robovacs, it didn’t seem feasible to spend that money per month just to end up with an unusable unit if I cancel the membership even after I’ve made enough payments to outright purchase the unit. The replacement items for Piglet are VERY reasonable (my first box set I just picked up for $20, and it has two brush rollers, four filters, four side silicone brush “things”, a mini screw driver, brush roller cleaner, and two other things I’ve no idea what they are).I’d recommend the Roborock S4 max. I’m happy with this purchase. And I hope Piglet is happy in her new home!

    5.0 out of 5 stars Best purchase I have made in a while!
    Reviewed in the United States on June 9, 2021
    I rely on reviews heavily when making purchases, yet I don’t take the time to write reviews for the many, MANY things I purchase from Amazon— until now... After researching numerous robotic vacuums- both well-known brands and brands I had never heard of before, I ordered the Roborock S4 Max. Best purchase I have made in a while and already well worth the money! I received the vac quickly and the set up and operation was so easy. I downloaded the app, connected to our WiFi, and everything has worked flawlessly. Our house is a little under 2,000 square feet and it vacuums our entire home on one charge (takes about an hour and 40 min., with over 35% battery life left upon completion). We have mixed flooring- most of the house being hard wood, and then carpeted bedrooms. It goes over and adjusts for each flooring type and gets our rugs, as well. The noise level is very quit and the suction is great. I wondered if I would second guess myself not getting a self-emptying vac, but I am glad I did not- there was no need! When I empty it after it has cleaned our entire home, it is full, but not overflowing (we have a cat that sheds and children running in and out of the house bringing things in on their feet, too. Just remember to turn the unit over occasionally to get the hair out of the brushes- we have three girls with long hair in our home). I have used the vac both while being at home and while away and it is so easy to see where it is at right from my phone. It maps out our home perfectly and gives detailed information such as meters cleaned, battery life, and amount of time it has taken. You can also create no-go zones and choose specific areas to clean, if you desire. This was a fantastic investment and has already saved me hours of cleaning. I have nothing but positive things to say about this machine and hope that its longevity is just as great.
