Roborock S7 MaxV keeps my laminate floors dust free.
Although the Roborock S7 MaxV is not light on the wallet it has proven thus far to have been well worth the money spent. I did several weeks worth of research before buying this robotic vacuum cleaner. I chose not to buy the new S8 because I have all laminate flooring, no carpet anywhere and the S7 single roller seemed the logical choice. I ended up getting the black S7 MaxV and the white Auto-Empty charging dock separately because it was cheaper and there did not seem to be anyplace selling both the units in black.
=== THE VACUUM CLEANING UNIT ===
* The initial rapid (no vacuuming option) LIDAR MAPPING is exceptional in it's accuracy although if a room has ceiling to floor mirrors the LIDAR laser ranging will think that what's in the mirror is another room and it will show on the map on your cell phone app. Just create a "no-go" zone for that area and no problem. With each successive cleaning the machine seems to fine tune it's "understanding" of each room. However if one completely rearranges everything in a room it may take a run or two for it to fully adapt.
* The OBSTACLE AVOIDANCE artificial intelligence exceeded my expectations. That said, when I do manual vacuuming I always move things around some to get to various tight spots so I do something similar for this robotic vac before turning it loose and I'm not lugging around a manual vac while doing so. Obviously if an object is very small it will not be considered an obstacle and it will go over it and try to suck it into it's dust bin. Sometimes an A/C power cord will fall into this category and it will wrestle with it and in my experience it eventually just leaves it but I just make sure I clear such wires before sending the gizmo on it's vacuum run.
The obstacle avoidance feature has 2 settings with one being less strict than the other setting. I use it on the less strict setting so that it navigates narrow spaces more thoroughly. This can result in it bumping a door that is ajar such that it shuts itself into a room and can't get out by itself to either go on the next room to vac or to the charging dock. I just wedge rubber door stops under the ends of such doors and they stay put during operations. The MaxV variant of the S7 has the more advanced AI obstacle avoidance system and to me was worth the extra cost. The newer S8 units have similarly capable obstacle avoidance systems using just slightly different technology.
* Roborock's mapping app for the cell phone does the job and and can be updated automatically. My only very minor issue with it is that when dividing rooms or marking off "no-go" zones on my smaller Android phone it can get a bit fiddly but I think most people have iPad sized phones these days so likely won't find this an issue.
=== THE AUTO-EMPTY DOCKING UNIT ===
* The docking unit is pretty straight forward and does a stellar job of emptying 95-100% out of the vacuum's sealed on-board dust bin into the sealed bag within the sealed container on the dock. The dock has an additional HEPA filter which prevents essentially any particles from escaping into the air around it. It can be rather loud during this operation which will at most only last 30 seconds. The empty frequency can be adjusted from "Smart", "Light", "Balanced" and "Max". the "Max" runs the full 30 secs and the other 3 are pretty much left up to the AI to figure out. Not sure what the diff is between the "Smart" and "Balanced". I just use "Balanced" and if in doubt manually run it from the app which will go 30 secs. I haven't filled the bag yet because it claims to hold 1-4 months worth of dust but that depends on how many pets, kids, foot traffic and where one lives as to how much service will be had from the bag. Also with this older (released early-2022) Roborock Auto-Empty units used with the model S7 MaxV vacuum a non-bag canister can be obtained which I purchased just in case inflation (no pun) makes buying bags a "no-go" zone. I don't think Roborock is offering that option with their latest S8 units. I just swap the container holding the bag with the special container using no bag.
=== THE APP USED TO CONTROL EVERYTHING ===
* I mentioned what I deemed the most significant aspects of the app above but it has other features which can be found in the manual and on Youtube.
Bottom line is I am most pleased with my new Roborock vac. It keeps my house clean with really minimal effort. I am a bit of a technical geek (retired programmer/analyst) so maintaining the thing is more fun than a chore to me. It also made me laugh one time when I sent it on a mission to vacuum the wash room. I heard the unit's voice announce that it was leaving the dock to go clean. It rolled out into the living room where I was sitting and at first seemed to be looking around as though lost moving to and fro then after a few seconds of roving it suddenly figured out what to do and went straight through the dining are to the wash room to finish it's mission. This likely is not as amusing put into words as it was to watch.
UPDATE 05-05-2023: After more time with this Roborock S7 MaxV I felt relating some additional experiences may be useful to some. Although I have not used the vacuum's mopping feature at all because my main interest is in it's vacuuming and superior navigational capability over time I began noticing my laminate flooring suddenly looking shinier. Mind you I hadn't manually mopped in an embarrassingly long time so this vac was doing better than I with my excellent Miele canister vac which I now only use to occasionally tune up the Roborock of accumulated surface dust from it's missions. The robot vac shamed me into actually doing a proper mopping of the floor. Now it will stay that way.
The point here is that prior to using this type vacuum it is very useful to first thoroughly clean the floors (or carpets) as a baseline THEN use this spiffy device to keep it that way on a daily basis as it has for me. I'm an older widower living alone now for 8 years and I try to keep the place as clean as possible. With the S7 MaxV it's like having a service regularly vacuuming the floors. I live in the mountains and it takes no time for dust to accumulate here so again I am quite satisfied with this particular robotic vacuum.
UPDATE 06-06-2023: After a couple months of owning the Roborock S7 MaxV and it's self-empty docking station I can say that using it to clean my laminate flooring once a week is more than adequate for a single guy living in a 2050 square foot single story home. I fired if up a lot the first week or so to assess it's capabilities. It was cleaning overkill for my purposes BUT I have zero pets and just one person with no carpets. My experience might have been different had I not first baseline super cleaned the house before beginning to use this vacuum. I mention this because I watched many reviews with videos showing problems with too much pet hair or "dirt" accumulated in the vacuum's dust bin before the thing could even finish a trip around their home's flooring. I've concluded that carpets are tougher for these machines which is why I have no issues with it's performance. Also if a home has 2 adults, 3 kids, 3 dogs, a cat or two and live in the country expecting one of these things to do a perfect job might be a big ask. Particularly if one does not have regular vacuum schedule adjusted to the amount of daily/weekly accumulated dirt. I get buy once a week but a household such as the one described above might require a daily run to avoid massive dirt accumulation in the dust bin before it's finished doing it's thing.
The bottom line here is that this machine appears to be well designed both from a hardware and software standpoint but even artificial intelligence and sturdy hardware have their limitations.

Fabulous robovac
Color: Black01
I bought this as a replacement for my iRobot Roomba j7+ (7550). We have been loyal iRobot fans for years but their quality lately has been subpar. The j7+ was a perfect example of it...I spent so much time messing with it getting stuck & having issues I might as well have pulled out the Kirby and just vacuumed myself. After research this machine constantly came back as highly recommended. So far, I can see why!! It does occasionally get stuck under my Island but other than that it works wonderfully and my floors are cleaner than they've been in a long time. The app features are great...I love that I can see mid function exactly where it has cleaned, it was easy to use and program. It works so fast too! The Roomba used to take 6 hours or so to do the 2200 sq feet on our first floor but this one usually does it in less than half that time. And it's soooo much quieter. I've been on Teams meetings with it in my office w/me and no one noticed. I highly recommend this unit!!

It’s not quite perfect, but it’s so much better than cleaning by hand.
I’m going to frame this review as a series of responses to what I imagine are common concerns for potential buyers.
Q. This version doesn’t come with the fancy dock. Is that bad?
A. Yes and no. The robot has an internal dustbin of perhaps 20 cubic inches volume, which is enough to clean a few large rooms in a row without filling up, but only if they’ve been cleaned already recently (which thankfully is usually the case after a while if you’ve set a proper cleaning schedule). That said, since the robot runs as little as once per week or as much as 4 full runs per day (“full run” here meaning the robot runs until its battery reaches 20% and it has to return to dock), depending on your schedule, if a lot of dirt is introduced or you haven’t run it recently, it can get tiresome to empty the dustbin manually. On the one hand, that’s still a lot less effort than manually shoving a vacuum into every corner of the space, but since the robot uses a semi-enclosed dustbin rather than a filter bag, you have to shake all the dust and fibers out of the bin by hand which inevitably leads to a small cloud of dust in your face and around your trash bin. I lasted less than a week before I decided to order the auto- empty, or “plus” dock.
Q. What about my privacy? I heard this model has a camera.
A. It does. It also has an onboard AI to process the images from the camera so it doesn’t need to send them to the cloud for processing. It’s not my job nor my area of expertise to tell you how much privacy you need, but i will say that I’ve had the robot for most of a week and my router has logged a total traffic of about 500MB from the robot. Since I’ve been monitoring the robot from my phone at work and used the remote access function, that’s a reasonable amount.
Q. Remote access?! But what if someone used that to drive around my home taking pictures of my stuff?
A. Well, assuming that they didn’t go to the effort of brute forcing their way past the encryption on the connection, they’d have to have your login information for the app (they’d have to know which brand of robot you got to even know which app to use) and they’d have to enter the dot-pattern lock code that the app asks for every time you use the remote function, and that’s assuming you enabled that function at all, as it’s disabled by default and can only be enabled by physically interacting with the robot. But even assuming that they got past those hurdles, they’d then have the privilege of directing the robot to crawl across your floor at ~5 inches per second while announcing that “remote viewing is active”, and they’d still only have a camera view from 1.5 inches over the ground, which isn’t a great perspective from which to steal someone’s data. Combine that with the fact that the robot is incapable of opening doors and the remote connection can be terminated by pushing any of the easily accessible buttons on the slowly moving robot, and you aren’t exactly left with the stuff of nightmares.
Q. What about the AI? Is it going to take over the world?
A. Well, I can’t be sure about larger AIs, but the one in this robot is nearly smart enough to avoid getting the robot trapped by chairs with crossbars for feet and not quite smart enough to find a way to roll over ethernet cables without tangling them. It helps the robot navigate and it lets you look at pictures of objects the robot has identified as obstructions (if you have that option enabled), but it’s not going to be thinking circles around even the average housepet.
Q. What about this mopping function?
A. I wish I could say that it’s amazing and I don’t think I’ll ever mop again, but that just isn’t so. Mostly it’s because my house was built over half a century ago and the robot was designed last year, but my kitchen is the main area that needs to be mopped and it is unfortunately filled with the sort of cupboards that overhang the floor by a couple inches - just low enough that the robot can’t get under them. As a result, the major splash zones right under the ledge go completely untouched by the mopping operation. As if that weren’t annoying enough, the mop attachment has no way to actually remove fluid from the surface it’s cleaning, so cleaning with it is kinda like putting a moist washcloth on a string attached to a stick and kinda dragging along the ground over the stains: not the most immediately effective option. That said, with enough passes and cleaning of the mop attachment proportional to the amount of material to be cleaned, it eventually gets most of the floor pretty clean. And since individual passes are essentially free as far as personal effort goes… it’s good enough I guess. I just wouldn’t go for this model if all you need done is mopping.
Q. What about the price?
A. Well, at 2-5 times the cost of manually operated vacuums, it is definitely an investment, and it does fall a little short in some ways. For example, it doesn’t agitate carpet as energetically as most vacuums and doesn’t suck quite as hard either, so it’s unlikely to get as much cleaning done on the first pass as other vacuums. Then again, each pass is a significant investment of your time and effort with a regular vacuum, whereas with the robot you just have to tell it where you want it to clean, how many times, and what level of suction or scrubbing to do and it will do the rest on its own (note: it will charge in between cleaning cycles if it needs more charge to be able to finish, but it will resume once it has enough charge and will remember where it left off. second note: depending on which dock you have, you may be required to intervene to empty the dustbin, as well). The other main flaw is that there are some things it just can’t do. The robot is incapable of fitting into tight spaces and can’t climb stairs, so cleaning those areas is right out. In addition, the vacuum roller is several inches from the edge of the robot, so while the side brush can sometimes push loose debris into the vacuum, that pretty much only works on tile, wood and other flat non-porous surfaces. Thankfully, humans and most of our preferred living partners tend not to travel those areas much either, but you can still expect to occasionally need to shove a conventional vacuum around into those awkward spaces. And of course the stairs. In any case, I suppose it’s a long investment, but some napkin math tells me that over the course of the next year, I’ll save approximately 40 hours of cleaning. Assuming the robot lasts past the initial year (given how easy it is to maintain, I rate that as very likely), it will have paid for itself by then in saved labor.
Q. If there was one more thing you’d add to make this product better, what would it be?
A. Fast charging. The robot will automatically attempt to return to its dock when it drops below 20% power. Using the basic charging dock, it takes just over 4 hours to charge after that. In a world where most phones can charge from 20% to 80% in less than an hour (some in less than 15 minutes), I’m not entirely sure why this robot takes over 4 hours to charge. There is something to be said for the longevity gains to be had from slow charging over fast charging, but I think I would have preferred a setting in the app with an explanation attached and a slot on the side of the robot for installing a new battery. I’d like to stress that this is not a critical feature of this robot, but it would be nice to be able to schedule all the cleaning for when I’m at work, but it requires too much battery charge, and the dock can’t replenish it fast enough.
Q. Overall, are you happy with the robot?
A. Yes. Very. I was happy enough with it when all it had done was clean my carpets, but for an extra kick, I decided to ask it to clean my garage, in which everything from woodworking to machining to welding is performed and which hadn’t been cleaned for 2 years. Not only did the robot not catch fire or explode (not even a little, though it did ask me to clean its roller), but it actually cleaned up all the dust, sawdust, metal filings, welding sparks and stray leaves! I honestly hadn’t been sure it would survive that sort of torture test, especially since the manual says it’s only for indoor home use and my garage is not the environment the designers meant when they wrote that. So far, I’m quite impressed and I just hope I can find a way to make it do its job without buying every accessory and replacement part under the sun, since you kind of have to expect that sort of nonsense with companies that try to convince you their product catalogue is a lifestyle.

Color: Black01
I own three of these. One was used at my former home; the other 2 were purchased for my 3 level new home (basement, 1st flr, 2nd flr).
"Are you crazy? Are you made of money? What a waste. You're lazy!"
It could be that all of those are true. It could be that none of them are. I believe that none of them are. I work A LOT. And while I am infatuated with the ease of mopping with those manual "tornado" spin mops, I am also an automation freak.
The older version (which is close to identical and uses the same parts -- which I still own and use) impressed me quite a bit as far as cleaning, vacuuming, mopping. It impressed me enough that when the other two went on sale, I purchased additional ones for this probably too large house. Total spend is probably $1,600 for all three over the course of 2-3 years. I also bought knock off replacement parts (filters, bags, mop heads) and they work great.
Here's what you do to have a good experience: I don't run them on a schedule. I manually run them. This forces me to walk the house to make sure there are no dog accidents or unnecessary debris on the floor. My robots have never encountered dog urine or dog poop so I can't really say whether this device would identify and handle it. I think I would like to avoid testing out it's avoidance abilities in that regard. But, I do want to get rid of anything laying on the floor so dog beds go up on the couch, scale gets picked up and stuff like that. If you are going to vacuum and mop, try to vacuum and mop everything. Phone charging cords and the most likely culprit for getting tangled.
Once I walk the house and see that there's an unobstructed path and everything has been picked up, then I run a cleaning cycle. You could choose a full cycle or just some areas or just some rooms. Useful if you work from home and do not want a robot in there. Works great. You can also define "No Go" zones on a map. Works great.
(My gf has those really long pile area rugs that are like fake animal fur -- like the pile is wispy and 3" long -- and these do not play well with those rugs -- they get stuck every time. No Go allows us to clean everything and the robot avoids the rugs perfectly.)
The bottom line is that you are the one with the brain, not the robot. Put the robot in a position to help you. Make the robot's job easy and you will be very happy. If you have pets or kids, DO NOT run it on a schedule Walk the house first.
1. Walk the area and pick up.
2. Check waste and water tanks and garbage bag and dump/fill if necessary;
3. Run it.
4. Dump/refill tanks so its ready to go the next time.
I will often run basement, first floor and second floor at the same time. The layouts are complicated, but the robots have no problem. It rarely gets stuck. Occasionally, a magnetic mop pad will come loose, which is an easy fix. For the most part, these things run very quietly and they do a fantastic job.
My basement is all tile and my workout room has thick rubber mats. The robot goes up and cleans the mats and cleans everything else very well.
My first floor is wood floors plus tile and includes a laundry room a bathroom, kitchen, etc. Because the floor tile is that 'rough stone' texture, it does make a clicky clack sound, but it also does a very nice job of mopping and vacuuming. We have a couple of low pile rugs and there's never a problem with them or anything else on the first floor. The area and room features are usefull to vac and mop the kitchen area after food prep.
The second floor has bedrooms with really old carpet and the rest is tile or wood floors. The vacuum picks up an unbelievable amount of legacy (before I bought the house) hair and dust out of those carpets. I mean, literally an unbelievable amount. Every time it runs, I will sometimes have to manually clean out the bin because of the volume of the hair. After the fifth or sixth cleaning, this is no longer an issue, but it still is pulling up so much legacy dog hair and dust. Quite impressive power.
I run these weekly or in addition as needed with a small amount (table spoon or two or three) of liquid cleaner like Mr. Clean or Lysol and that seems to work very well. I'd avoid putting in a lot because you do not want internal parts to get 'gummy' or clogged.
Overall, these are some of the best technology I've ever purchased. My oldest is maybe 3 years old and still runs perfectly. I look forward to using these for a long, long time. They save me probably 3+ hours per week.

As my initial review, it's a worthy robotic vacuum
As a rule, I do not write reviews based on a few days of use. I’d give it a month or more, observing how it performs. However, in the case of Roborock, I decided to make an exception, I was, quite frankly, a bit impressed by its performance.
Hence, the following is my initial report about S7 MaxV robotic vacuum.
At first, for many years, I owned Roomba and, since years ago it was the only well-known robotic vacuum, I was happy having such a toy. I did not make a reservation, calling my Roomba a toy, despite paying for it over $900, I did not see much use and enjoyed the first “robot” in my house. I was working on a third floor and heard Roomba vacuuming on a first, often bailing it out when it stuck under kitchen cabinets or some other obstacles.
Years passed, and a month ago, I purchased Eufy G40+ (with a cleaning station) to see if 15 years of robot vacuum development made a leap. Well, if to judge by G40 (~$400), it was far from a leap, more of a stumble. But the reviews, and the price, were good. But a few weeks later, I couldn’t take it anymore, watching as the unit would “stuck” in a totally unobscured area, lifting it, placing it nearby, and watching as it would take about six minutes to cover less than 3-5 feet to get back to its charging station (video is available)
I decided to replace Eufy with Roborock and got two units; a Roborock S7 MaxV ($640) and an automatic vacuum station ($300). Since I ordered them separately, the station came a day later, and, for a day, I used S7 as is with its standard dust bin.
Again, time will pass, and I’ll amend my review, giving a more comprehensive statement. But initially, comparing S7 to Roomba and Eufy G40, I was pleasantly surprised. It works just as one would imagine a vacuum robot must perform.
First of all, it’s quick.
It took just one run to map the first floor very accurately.
It’s doubtless.
S7’s cameras, lidar, and all its sensors guide the unit with bewildering precision. Especially on the second run, I was utterly enjoying watching how it was "hugging" every corner, chair legs, cat dishes, electric candles (my wife placed them on the floor), and so on. It seemed that the robot built my house and was very familiar with the floor plan since it was born. I was also impressed that I did not see yet S7 bumping into any obstacle, it slows down and stops, leaving less than a few millimeters between its front pannel and any barrier.
Dust collection.
That is a bit funny. My wife does everything very diligently. She vacuumed the first floor a day before S7 arrived and was a bit surprised when S7 collected almost a full dust bit on its first run. The next day, we used it again, and when I sent her a picture of collected dust (albeit not as much as on the first day), she replied that in her opinion, S7 had some dust hidden inside its body and now it was just showing off. Well, not only it did a great job, but it also was very quiet, considering that we are talking about a vacuum.
The application.
It is ok. A bit buggy, but useful and comprehensive. You can create and name rooms, make no-go zones, and so on. I’m sure the company will continue improving its functionality. But my general complaint/wish is to see the application designers stop using almost the same colors for font and backgrounds. It is so difficult to read and understand anything if texts are written in a small font and the color (of the text) blends with the backgrounds. I wonder who was the first “genius” who decided to implement such a “clever” trick. How must a person with dilapidating eyesight abilities use such apps?
Thus, as a conclusion to my initial impression - S7 MaxV is worth every penny and an automatic dust evacuation unit only adds great value to an already very capable machine.
To be continued.
