Amazing cleaning partner!! Love!
Color: Black - 03
This is my first robot vacuum and I'm in love with it! I love being able to be doing something else, folding laundry, making dinner etc while this is cleaning the floors. Harry, as I've named him, is my cleaning partner. While it by no means replaces the suction on a standard push vacuum It's great at those between cleanings to keep things picked up. We have a dog with long white hair and a cat so hair clean up is always an issue and I'm very ocd about my house being clean. The suction doesn't leave my thick carpet hair free by any means but it's a great help to keep up with it. I read a lot of reviews before buying so wanted to share my experience after having this about two months now and using several times a week. I vacuum the house during the week with Harry and he mops my hard floors on the weekend...and I do a stand up vacuuming with my big vac on the weekend. I hope this helps you! Here are some of my thoughts on how this thing "Harry" works:
MOPPING. This feature is amazing!!! And one of the few robo vacs with the option. I love being able to put a little cleaner and water in the bin and let it do its thing. This model doesn't have the ability to map rooms you want it to clean in (if your carpet butts up to hard floors) but I found an easy solution. As my bar stools and garbage cans need to be moved so Harry can mop everything I just use them to block off my great room so it stays on the hard floors. Leaves my floors pretty dang clean and smelling good, while I do other things! You can also buy magnetic tape to block room's but I don't see the need with my blocking technique, and I just close the doors to my carpeted bedrooms. Wet the pad on the bottom before starting to help get it going, the water in the container slowly seeps out so getting the pad wet ensures its starts mopping right away. Will need to refill water bin about every 30 min. I use a little fresh scent pine sol then fill rest with water.
SUCTION. The suction is great on hard floors gets everything up. The side sweeper is great against walls and cabinets. I have thick carpet so didn't expect it to suck everything up but it does a great job. Still leaves my dogs hair behind a bit. I use my big vacuum once a week for a deeper cleaning. For what it is this little guy does pretty good!
OBJECT AVOIDANCE. My husband wanted the model that is twice the price or more that has the laser mapping eye. Not sure how that works but for the price this works just great! It senses something before running into it, slows down then gently bumps it and turns around. Also the low profile is great for getting under beds and dressers where hair and dirt hides, love this! Not saying I wouldn't like the laser mapping eye but didn't want to spend 2x+ the amount and this has proven to work really well.
NAVIGATION. While I know other models are more technologically advanced again for the price this works great. It vacuums in straight lines which is great for my ocd. If it runs into an obstacle it can get off track from those lines as its works it's way around things. Sometimes it seems confused and goes back and forth in the same area, but generally works itself out and keeps going. I would like to be able to control where it goes in the house but not available on this model, but again for the price I'll say I don't really mind. I just let it go where it wants or shut it in an area if I want it to stay in there.
BATTERY. The battery is pretty great. Runs for 2+ hours before needing to charge. I have a 2,700 sf rambler and it can't get through the whole house before needing to charge. If it were a tad more efficient in navigation it probably could, but does spend some time trying to figure out where it is and where to go. I just charge it and set it loose on the other side of the house.
MAP/APP It has a map feature that is only to show you where it went during the clean up. You can't interact with the map or tell the vaccum to work in certain areas with it. But I knew this when I bought it so wasn't expecting that. If you are looking for a vacuum you can tell where to go then spend more for the upgraded models. I don't feel a huge need for this, works fine for me. The app is more for basic settings, you can turn it on and off and see what it's doing, battery life, have it call out to you if you can't find it. You can hook to Alexa which is awesome to say "tell Harry to start" and off it goes. Again you can't control its direction or rooms work the app it's more for stop/go and basic settings and maintenance.
STAIRS. We have a sunken living room with a step.down the whole length if the room, hasn't fallen once. Its senses the step, and moves away, kinda bounces along the step turning, Sensing and moving it's way along it. Perfect.
DUST BIN. this model has one of or the largest bins on the market, its holds a lot for hours of work. It's easy to access right on top, open the side and empty. The filter pops out so you can clean it, found taking outside and bumping on concrete left a good amount of dirt.
NOISE. I think it's pretty quiet for a vacuum cleaner. I only have my noisy stand up to compare to and its much quieter than that. It's basically just the light suction noise, I don't hear the motor at all.
OVERALL. For the price this is the best investment I could have made to help keep my house clean during the week while I'm busy with work. I love being able to start it and walk away accomplishing other things and come back to clean floors. It's a little misguided at times but nothing bad. I'm sure more expensive models are a bit more intelligent but for $350 this is the best option out there. I would highly recommend if you need a helping hand. My favorite feature is the mopping, I hate mopping floors and this does the job for me! This thing is amazing and I can't believe I've never had one, will never be without now! Happy cleaning!!

Vacs AND Mops Great!!! We love her! 🩷
Color: White
This little machine (lovingly named Yvette) does an amazing job!! I was skeptical of its mopping capabilities after reading mixed reviews, but I can attest that it does a great job lightly mopping (not mega gross sticky messes, just water stains and normal dirt). I included a video. The vacuum function is also fantastic. The only issue so far was a chair with a bar that goes across the floor. She got stuck on it and had to rescued. While she navigates extremely well in our single-story home with tile, vinyl flooring & low pile rugs, she does ruffle up the rug corners a bit on the lighter-weight ones. I just pick them up and toss them in the wash while she cleans. I will say you need to pick up your charger cords! She will swallow them whole and keep on going 😂 The good news is, the roller comes out easily and nothing was damaged. The cord was fine also. I think this was a great investment. It is a little loud, but nowhere near as loud as a standard vacuum cleaner. Just make sure to pick up toys, cords, dog toys…just like you would if you were doing the work, and all will be fine. I ordered disposable vac bags and a kit with extra mop cloths, roller, cleaning tool and brushes. It only cost about 20$. Well worth it!!! The battery life is good, but I do mop in the “zone” function rather than the whole house. That way I can put a new mop pad on and top off the water and Yvette can take her union break (charge up) before going on to the next area😉. She does manage to vacuum the entire house without needing to charge, which is awesome.

Exceptional Performance! It works!
Color: White - 04, Color: White - 04
Let me start by saying I have purchased no less than 5 robot vacuums over the years and every single one led to disappointment in their operation, performance, and/or features. So my expectations weren’t the highest, but I was hoping the S7 was worth the hefty price and wouldn’t be a another dud.
The Roborock S7 was by far the most expensive robot vacuum I’ve ever purchased. I never went over $350.00 with my previous robot buys. But after reading reviews and specs of the S7 and comparing it to countless other vacuums for months and debating with myself about buying the S7, I felt I had researched enough and went ahead and gave it a go. Wow! I am so glad I decided on this particular robot vacuum!
**************
The vacuum:
The suction is great and the carpet boost really helps pick up dog hair from my three large dogs that are constantly shedding around the house and on the living room rug they like to sleep on. It’s actually pretty unbelievable how well it picks up dog hair and dust/dirt off my rugs, tile, and hardwood flooring that the dogs bring in all day. I love how it is able to get under my beds, most furniture and two couches. I neglect those areas pretty frequently, so it’s nice to not worry about dog hair and dust piling up under them.
The S7 is amazing when it comes to vacuuming. It is seriously efficient, you can see where and what room the robot is in via the app and the progress it is making, and they battery life while running is fantastic. Speaking of the app, It is wonderful and easy to use - I love how you can send the robot to vacuum different rooms or certain spots in the house as well as the number of times you want it to pass over the selected room/area.
The no go areas and invisible wall functions work perfectly. I’ve had no issues at all setting them up and the S7 recognizes them every time.
I’ve had no issues with the robot getting hung up or stuck on something while running. It’s the first robot I’ve had that didn’t need full time babysitting while it was vacuuming. The navigation and mapping of my house are both exceptional. It still runs into certain things but is able to recognize and move around the object.
As soon as it has finished cleaning, the S7 will return to the base and empty itself in its bin (if you purchased the auto empty base) and start charging itself.
—— Vacuum CONs:
As far as my personal observations go, I can only note one con and that’s with the bags for the the auto empty dock. I wish the bags were washable and reusable. I get that the current bags are sealed and keep the dust/debris inside the bag and out of the air and off the floors, but a reusable bag would be great for some buyers who try to keep unnecessary waste to a minimum. For some, the sealed bags wouldn’t be an issue at all and could possibly be a pro. But for me, it’s a small annoyance.
**************
The mop:
I love that you don’t have to switch out attachments between mopping and vacuuming. The S7 can mop and vacuum at the same time, which is so convenient.
Mop CONS:
—— You can only use water in the mop tank, which I know some buyers didn’t like because it doesn’t sanitize the floors at all. My work around is using electrolyzed water, which is as effective as bleach at killing germs. Google force of nature cleaner if you want to use water in the mop to sanitize. I’ve had no issues using electrolyzed water and it makes the house smell clean and deodorized.
—— without a doubt you will still need to mop your house. The S7 is great for in-between mopping days. When it rains, my dogs track mud in onto my tile floors. The mop function isn’t going to get the mud up well enough. It will get some up, but not enough to be satisfied with the result. But it does great for very light mopping jobs and mopping under most furniture so you don’t need to move things around to mop underneath.
***************
Bottom Line:
Seriously, I can not recommend the Roborock S7 enough. I would buy it again in a heartbeat. While it was the priciest robot vacuum I’ve ever purchased by a long shot, I’m so glad that, for me at least, it was worth getting over the price sticker shock. It performs fantastic when it comes to vacuuming and the mop function is great for light mopping between good old fashioned bucket and mop cleanings.
The S7 gets a rating of 4.7/5 from me. It exceeded my expectations by a miles!

Charge. Press button. Floors cleaned!
Color: White - 03
In a nutshell, you will LOVE this vacuum if you have smooth hard surface floors like luxury vinyl planks (LVP), hardwood, etc. Truly, it’s the best thing since the automatic washing machine!
It also does well on tile floors for vacuuming, but for mopping, it’s basically is a Swiffer so your grout may not be as clean as you want. I don’t have carpet, but I have 2 small rugs. It recognizes when it switches to rugs/carpets but it takes a couple seconds for it to kick into “Max” suction, so my rugs were only partially cleaned.
The details…
FYI, you’ll need an outlet area with quite a bit of clearance around it for the charging base – 3 feet on either side and 5 feet in front of it (per the manual). Allow about 4 hours for it to fully charge for the first time.
Installing the app on an iPhone and connecting the vacuum to your 2.5 gig Wi-Fi (after entering Wi-Fi password) you: 1) Click on the button at the bottom of the app to proceed.
2) Your Wi-Fi settings open, then you click on the Roborock.
3) Close “Settings” and click on the Roborock app. Now the Roborock S5 Max is setup.
OK, I named my Roborock “Rosie” (after the Jetson’s robot maid), so “it” is changing to a “she”. 😊
Vacuuming: Just press the button on the Roborock and she says “Starting to clean” and takes off! The first time cleaning she’ll make a map of your place, which you can view in the app. She uses her external brush on the right side to sweep in dirt toward her and then vacuums it up! She really digs into areas while cleaning around obstacles. She swept in my small walk-in closet but didn’t disturb my clothes that were hanging to the floor.
BIG BONUS: her low profile allows her to clean areas that I very rarely clean! She went under my beds, night stands and dressers! She even went BEHIND the couch! If she can get to it, she’ll clean it! But on the flip side, make sure you don’t have things like boxes, power cords, etc. which can get in the way of cleaning.
The app shows the power settings for vacuuming: Balanced, Turbo and Max. It’s defaulted to “Balanced” mode which appears to be lower suction for hard floors and it increases power when it’s on a rug. On that note though, she did not do a good job cleaning small rugs. I have LVP throughout the condo and tile in the bathrooms. I like running her on Turbo mode which is slightly noisier and uses a bit more power. If you have tile floors with grout, it might be better to use a higher suction mode to clean the grout better.
Repositioning: Originally, I plugged her into a spot that had the required clearance, but thought I’d try a different spot where the bed is only 4 feet in front of her, BUT she can go under the bed, so that gives her the clearance she needs. When I started her up in her new location, she moved forward, looked around and then said “Positioning”. Then she roamed around the room and briefly outside the bedroom and said “Positioning complete”. Now she knew where she was and started on her merry way vacuuming the condo!
No go zone: I didn’t want her to chew up my tree skirt around the Christmas tree so I used the app to draw a “no go zone”. You can draw a box on the map or in my case, I drew some lines. Sure enough, she didn’t go past the lines I drew in and my Christmas tree skirt was spared!
Bottom line: 17 stars out of 5! She does a GREAT job and I love that she vacuums UNDER things that I typically ignore. The mopping is also a great feature that helps your floors look fresh and clean. Although this doesn’t replace YOU vigorously mopping your floors, it definitely helps to keep lightly dirty floors cleaner. I can’t say how well she works on carpet, but if you have mostly a hard surface floor, she’s a HUGE help!

Highly Disappointed
Color: White
After years of owning a Roomba I decided I wanted to try a new robot vacuum so, I bought two of these vacuum/mop combos. Initially I was impressed with how nice it would make my carpet look after vacuuming and it did an okay job with mopping. I know it is not intended for a deep clean mop, but it really just wet the floor. My first vacuum started acting up about a month after purchase making noises and it required a factory reset. After I did the factory reset it kept giving me an error message that it need the factory reset and it would never clear out. I returned the vacuum and purchased another one in hopes that I would get better outcome. The second vacuum constantly had an issue re docking so I had to move the dock station around to multiple locations and it still would not dock all the way. After about a week I started getting an error to clean the main brush so after I checked and nothing being stuck in the brushes the error would never clear out. It also started making a loud noise and I tried a reset and nothing worked. This one only lasted about two weeks and I did a return several weeks ago and I am still waiting on my refund. Very disappointed as I had high hopes for this vacuum/mop combo. Needless to say I will be returning back to a Roomba.
