Seriously I was AMAZED how good this cleaning robot was. I've always been skeptical about cleaning robots aimlessly bumping about the house all day "cleaning." However there is a HUGE difference between a robot that cleans aimlessly and one that cleans methodically. This robot is the later. Even when I heard that it is a methodical cleaning, I was highly skeptical about its capabilities. I figured it'd get lost, get stuck, become trapped and die not being able to go back to its charger, etc. BOY WAS I WRONG!!!
The robot works by spinning a laser on its head that maps out its surroundings and crates a map of your home. The laser is surprisingly accurate, I can see individual chair legs and sofa legs of my furniture on the map. It then rolls around your home creating a physical border that defines the rooms. It then "fills in" the map area in sections with consistent back and forth runs.
The best feature of the robot is that it's surprisingly smart in its path-finding. It doesn't just reject an area as soon as it bumps into something like chair leg or even a wayward movable object. It tries to CIRCLE around the obstruction. The difference is that it squeezes itself into the nooks and crannies of hard to reach objects to clean them instead of just leaving them blank. The first time my robot bumped into my chair leg, I thought "Oh great" it'll think that it's a wall and nothing under the chair will be cleaned." Instead it kept probing itself around the leg and eventually squeezed itself between the chair legs and cleaned underneath the seat. Furthermore, the chair was next to a row of other bar stools creating a tunnel of legs and the robot squeezed itself between all the legs and cleaned underneath them. It astonished me even more that it found its way back out of the tunnel of legs and back onto its route!!!
I'm constantly expecting it to get stuck somewhere and get lost leaving entire areas of my home uncleaned but so far it has not happened. It even works on my rugs (low to medium pile carpets) quite well - going from carpet to hardwood floor with ease. Others have complained about carpet use but so far it's not been a problem for me. The only problem I've had so far was that it can't cross the bit of marble floor stop that separates my living room from the bathroom. The floor stop seems to be too high for it to climb over. Finally it does not do well with cables and wires. Loose charging USB phone cables and extension chords get tangled in its rollers and once I found it back at its charging station with an iPhone USB charger stuck inside. It dragged the cable around the entire apartment. I've learned to secure loose cables so they don't get in the way. It is a vacuum after all and all vacuums' weaknesses are loose cables. Additionally I've noticed since it maps with a laser, I have a floor mirror that reflects the light. My robot thinks my floor mirror is a magical portal to a new dimension.
Noise is surprisingly quiet. I was expecting a hive of angry bees but it's a dim hum. There's not even a huge difference between the "balanced" and "max" speeds. I actually fell asleep once while it was cleaning. In terms of suction, it's not as good as a dedicated vacuum like a Dyson. I've tested by throwing a few torn pieces of tissue paper next to it while it was running. The tissue paper didn't get sucked up. It only sucks up items right underneath it, which is find considering it runs in tight parallel lines around your home for max coverage.
The app and Alexa integration is also great. I set biweekly cleaning schedules when I'm not home to maintain a high level of cleanliness. It's so smart and dependable that I feel comfortable with it running without any monitoring. I can be at work and track its progress on my phone. I can also tell it to clean a specific area on the phone app, draw a do not enter area, or divide the apartment by rooms to clean a specific room. Finally the Alexa integration is also great, I can easily tell Alexa to clean the apartment. It also has a great spot cleaning feature where you pick up the robot, and clean the spot-cleaning button and it will clean a small area where it was placed.
I have not tried the mopping feature yet. By most review accounts it's not great as it just drags a wet rag around the room. It also doesn't stop on carpets so you'll get a wet carpet from using it. I'm not expecting much but I primarily use it for vacuuming anyways.
If you're looking for a robot vacuum, I wholeheartedly recommend this! This is so much better than "dumb" robots that bump around randomly. Cleaning my 780 square foot apartment takes approximately 45-50 minutes which is surprisingly fast and took only 35-40% of my battery. Every time it runs, I'm constantly surprised by how effortless and smart the path-finding is. Until now I was never a believer of artificial intelligence but I am now!
All hail our new mechanical overlords!

-Mapping-Only requires one run through an area to develop a complete map of the floor. I have two floors and it mapped both floors perfectly. My previous vacuum required 2-3 practice runs to develop a map and even then it still considered a downstairs room which was about 80% of the size with a different configuration to be the same as an upstairs room. Via the phone application, one can place no Zones for vacuuming and no Zones for mopping on the same map. Sizing the no Zones takes some trial and error. For my no mopping zones, I had resize the no go Zones 3 different times to perfect this for one area.
-Navigation-It is very efficient and takes less than 1/2 time to vacuum a room/floor from the iRobot i7. A room that took the iRobot i7 37 minutes takes the Roborock s6 16 minutes. The application allows you to see in real time the vacuum path that Nikola is taking. It also does not bump into walls or furniture like other robotic vacuums, which the i7 did; so I named it Mr. Magoo. Also, because it uses Lidar, I can vacuum the entire downstairs at night without turning on the lights.
-Battery life-It is said that the battery life is up to 180 minutes. This is true only if one is using it on the lowest suction. If you have all medium pile carpet, the battery life is closer to 90 minutes. The vacuum will return to the docking station when the battery gets to about 20-25% of its charge. When it charges up to 75%, it will restart from the area it left to finish that area. My downstairs, approximately 1,200 square feet, is a combination of medium pile carpet, 15% of the area, low pile area rugs, 35% of area, and hardwood floors, 50% of area, and this takes the vacuum 71 minutes. Upstairs, 1,500 square feet, is 90% medium pile and 10% tile and this takes about 93 minutes of vacuum time which does not include time to recharge as it drops below 20-25% charge.
-Quiet. It makes so little noise compared to other robotic vacuums. I am able to keep the tv on normal volume and Nikola can vacuum away.
-Software-The updates are great. With the latest update, you can map and save at least 2 different floors and I believe up to 3 floors. The vacuum can now clean over carpet that has black patterns or color whereas before this was not possible. My favorite part of the application is the "Maintenance" screen that shows how much time left to replace/clean certain parts of your vacuum. For example, I have 131 more hours left and then I should replace my filter or in 11 hours more of vacuum time, I should clean the bottom cameras/indicators on the vacuum, etc.
-Mopping-I was not looking for a mop in a vacuum but I'm pleasantly surprised at how well the mop function works. The mop tank is not large but it can mop about 1,000 square feet of flooring. I used mostly water and some Bona to mop the hardwood floors and it seems to do a good job.
-no Handle-My only suggestion would be to include a built in handle for the Roborock s6. It takes me 2 trips to move the docking station and the vacuum from one floor to another only because the vacuum unit does not have a built in handle that I can carry with only 1 hand.
-6-5-20 Update on Rugs with black patterns. After my review, I noticed a number of others indicating that the s6 does not vacuum over rugs with black patterns. I read the same on various forums before I purchased Nikola. In fact, in the Facebook Roborock group, there was an entry on October 2019 that showed an s6 user with the same rug that I had (shown in the above photo) where he said the s6 could not navigate over his black patterned rug. So, I purchased a non-black patterned rug at the same time I purchased Nikola. (I hate needing to purchase one thing after buying something else; just like there is no such thing as a "free" dog.) Both the s6 and the new rug were supposed to arrive on the same day. Unfortunately, the rug arrived a week later but I was anxious to use Nikola. Over the week, he easily vacuumed 3 different times over my rug with the thick black patterns.
Thus, I’m assuming there was a software update that arrived after viewing the October 2019 entry in the Facebook Roborock group forum that allows for the s6 to vacuum over rugs with thick black patterns. Or, the hardware that came with my white s6 is a later version to allow for this.
