About this item

  • Revamped drivetrain and ultra-Precise Laser Navigation, as used in autonomous cars, makes it harder to trap robot vacuum, even in complex environments.
  • Comprehensive app control, including map saving, no-go zones, and power setting, give you total control of robot vacuum no matter where you are.
  • Intense 2000pa Suction, enough to lift AA batteries, easily picks dust off floors and can even drag trapped dirt from deep inside carpets.
  • Supersized battery, good for over 180 minutes of non-stop cleaning, is more than enough to clean most homes in one session.
  • It precisely maps an entire level of your home and can recognize up to 4-levels. Put it on the floor you need, press the Clean button, and it will figure out where it is and automatically apply any No-Go Zones and Invisible Wall you have in place.

Quiet design

App control

anti-falling

Multiple Cleanup Modes

Choose the right cleanup mode for any given need, with 5-levels of cleaning power, generating increasing amounts of suction and noise. Available modes are Quiet, Balanced, Turbo, and MAX.

Surprisingly Quiet

Powerful suction does not have to mean loud. The robotic vacuum treads a delicate balance giving you maximum power for less noise so that you can clean with less disruption to your home life.

Total App Control

Control the robot completely from anywhere with an internet connection. Start or stop a cleanup, set schedules, change suction levels, and more.

*Note: Only works with 2.4G Wi-Fi.

Built-In Fall Protection

Clean right to the edge of stairs and ledges without worry. Four onboard cliff sensors, two in front and two in the back, scan the ground and stop the robot from going over edges.

Automatic Top-up Charging

When cleaning larger spaces, the robotic vacuum will clean until its battery is low, then it will return to its dock and recharge to 80% capacity before continuing with the cleanup.

Remote Control

Take control over exactly where the robot goes, and drive it to where you need it using either the “Pin & Go” function or by driving your robot using virtual joysticks on your phone.

Accessory Maintenance Scheduling

Various robot vacuum accessories will need cleaning and replacing at different times. Use the app to check when each item needs to be checked and even receive recommended replacement notifications.

Floating Main Brush

The floating main brush adjusts its height for the perfect clean, dropping close to the ground when cleaning hard floors and rising on the carpet for proper carpet agitation.

For Optimal Use:

Use on low- to medium-pile carpets, tile, wooded and hardwood floors. Not suitable for high-pile carpets.

I REALLY wanted to like this vacuum
1 Star
I REALLY wanted to like this vacuum
I had been researching robot vacuums for a few months and when some of the side-by-side vacuum review sites started talking about the Roborock S4 being the new "must buy" robot vacuum, I was pretty excited. Amazon had a $40 off discount for early buyers, and so my sales pitch to my wife began. She wasn't wanting to spend the money, but I convinced her that it would allow our house to stay more clean without work from us.We are on the tail end of a major 7 month (and counting) home remodel job and we put in new hardwood flooring through most of our upstairs as a part of it. That means that any bit of dog or cat fur stands out pretty easily, and my wife is a bit OCD about clean floors. Sounded like a great match, so we jumped in and bought it.We didn't try it out right away as there were too many known obstacles due to construction, but after a few days, I wanted to try it out. The floors were bare except for some basic furniture, and I blocked off one section of the dining room where there were tools and such as well as the main hallway since some work was being done down there so that the Roborock would just ignore it. Things seemed to go well... for the most part.It got stuck a few times on the bare floor. That's right. It struggled going over pretty much every floor vent. We have 4 different styles down currently as we decide which one we are going with long term. They are all just barely above the surface and none of them have large gaps. Oh, and the S4 wanted to suicide itself down the stairs. Twice during that first cleaning, it went along the top edge of the stairs, and dropped one wheel over the edge and stopped. I didn't think too much about it because I figured that after it mapped the house, I could just put a no-go line there. I did this test during the day when I was home, but my wife was not. I wanted to work out the bugs before showing it to her.Fast forward a couple of days. Time to try the cleaning again. Same setup as before, and off it went. It got stuck in all of the same vent spots, but managed not to drop a wheel off of the top of the stair (YAY), and it was pretty cool. We weren't sure what to do about the vent covers though, and after getting stuck on the 6th one, we canceled the vacuum job as we were leaving the house.Then it happened... We opened up the rest of the floor after tools and construction to the floors was done. Put the rest of the furniture in the house, and put down some rugs.The Roborock started off and I had high hopes. Now that the whole floor was open and everything was in place, I could finally get the full map of the house to set any no-go lines and areas... My enthusiasm was short lived. Stuck on air vents, ok, we knew that would happen, but then it got stuck under the dining room table. The chair legs are big enough for it to fit through, but it just bounced around under there for a solid 10 minutes before I had to move a chair to let it find its way out. I thought that the S4 was advertised to be smarter than that??? And then it found the first rug... Stuck... Alarm goes off that it is stuck too. It never made it on to the rug, but had bounced around between a rug, a kitchen cabinet, and the refrigerator long enough that it errored out. Hmmm. Maybe I need to just move the rug a couple of inches to give it some room to work. Nope, it couldn't seem to make it on to the rug. Most of the time (like 98% of the time), only one wheel would go up on to the rug, and then it just couldn't get on the rug completely and would wiggle around over and over and not make progress.I know what you are thinking... Must be thick rugs or shag rugs or something... Nope. These rugs are significantly thinner than a threshold that the Roborock managed to go over, are just normal low pile material, and don't have a pad or anything under them (although we want to add a pad to the main one in the living room at some point). The Roborock just couldn't sort out how to get on to the rugs. The 2% of the time that it did get on a rug, it vacuumed just fine, until it went off the rug and tried to get back on.Not only could it not get on to the rugs, but all of its wiggling around would cause it to not map the house correctly. It thought that it was in the dining room when it was still in the kitchen. It was taking areas that it already cleaned, and then duplicating that area about 15 feet away on the map because it saw it as a new area, it was skewing a large portion of the map on to a 45 degree angle, which really made it get lost.At one point, it was cleaning a random spot on the map, and then its laser saw something that made it think that it was somewhere else and it literally just "jumped" to the new location.Again, every time it got stuck, I tried to leave it exactly in place and just lift it up and back down to reset the error and move the obstacle, or move it only an inch or to so that it would be really close to where it thought it was.Sadly, all of these issues just make it impossible to use. Even if it didn't get stuck and send an alarm for help, it can't map the house correctly, and even if it could do that, it is so noisy when it tries to get on to a rug. We can't run the vacuum at night because this would be too noisy (and it would never finish anyway), and we can't run it during the day because I just don't trust it not to get lost.Maybe we got a bad unit or damaged unit. It was brand new, and while the Roborock boxes (they double box it which is nice) weren't daamged, Amazon put it into a much larger (more than twice the size needed) box and didn't have many of those air pouches for packaging. The Roborock box was free to bounce around inside the larger box and we know how rough the trip can be from warehouse to home.A lot of people LOVE this thing, and I know that this isn't the normal case, but it was absolutely terrible experience for us.I took a number of videos of it getting stuck on the edge of our rugs, and saved screenshots of the swirly motions it took when it encountered the edge of a rug trying to get on to it and how messed up the mapping is.I've included one photo with some comments and things marked.Red is where it was getting stuck on rugs and swirling around. This seemed to be the cause of the rest of the problems.Pink is where it was lost enough that it re-mapped areas, duplicating them because it thought that they were new areas.Blue is where it lost total orientation too and skewed a chunk of the house 45*Green is where it suddenly went from one spot and "transported" itself across the room. It was not picked up or anything, just jumped. At this point I just canceled the cleaning and boxed it up. Sorry Roborock S4, but it just wasn't meant to be.Again, good luck to everyone else. This seems to be a great vacuum for a lot of people, and I REALLY wanted to like it, but when it can't even go on to a low pile rug (even though it can vacuum it if it does make it on to the rug), and then it just gets completely lost/disoriented, it just won't work.PS. Roborock, if you are listening, have someone who speaks English proofread your app. Some words are misspelled... "Enc current cleanup and reset vacuum power?" I assume you meant "End" and not "Enc"? I saw a couple of others too.

5.0 out of 5 stars Full review. Works very well!
Reviewed in the United States on May 24, 2020
The Roborock S4 had been cleaning every other day for a month now. It works very well but lacks a few features. I have 16 inch tile flooring in living room, kitchen and baths. The tile is uneven or not level is a few area's and will catch the corners when cleaning will Bissell crosswave pet. Roborock doesn't have any issues with this. I'm sure if it had the moping attachment it would. We have Dark sealed laminate in bed rooms and hallways.
The S4 does just fine on low pile area rugs and foam bath mats. Even cleans the 2x4 ridged entry rug by the back door just fine.
Has lots of power. I run in balanced mode and it does pick most things up out of the tile gaps. We live in Texas so we get alot of dry grass and sandy dirt tracked in. Corner cleaning is okay and it does just fine under furniture that it will fit under. Around of 4 inch clearance is needed. My bed is 3.4 inches and it will not go under there.
The noise level is just fine in balaced its just a little louder than the microwave. In silent it's a little quieter than the microwave but lacks a little power on silent mode doesn't pick up small sandy debris from tile gaps.
Navigation and mapping are very nice and work well. It's never gotten lost or stuck. The instructions are not that great so it took me awhile to figure out the map to add rooms and no go areas and lines.
I did bump a star for poor Alexa integration and lacking a few other features. You can't tell Alexa to "ask roborock to clean" or "ask roborock to clean the kitchen" nor can you add it to routines where you say "Alexa Good morning" and she tells you the weather turns on the lights and starts the vaccuum. So that is alittle disappointing. It does work with Alexa you link it ask Alexa to open Roborock and then ask it to clean or return to dock. Only commands I've been able to get to work but it is only a whole map clean. You also can't label rooms in the roborock app. The maintenance features that tell you when to change clean ir replace items is great.
I really like the lidar navigation system and not needing lights to navigate well. I really wish Roborock had a self empty bin. The bin size is fine but I do have to empty it every run or every other. If you have long hair dogs that are heavy shredders like sheperd or
husky this may be an issue.
The S4 does just fine with short hair. I do how ever need to clean small amounts of my foot long hair out of the brush roll about once a week.
Overall for the $320 plus tax The Roborock S4 was worth every penny. Almost got a Roomba I7 but decided to save some $$. It would be nice to see some app improvements and better Alexa integration. As well as a self empty bin set up.
