Best Robot Vacuum I’ve Ever Owned – Worth Every Penny
I’ve had the eufy Robot Vacuum Omni S2 for a short time now, and I can confidently say this is one of the best purchases I’ve made in a long time. This isn’t just a robot vacuum—it’s a complete, all-in-one cleaning system that truly feels like having a professional cleaning crew built into your home.
First off, the performance is incredible. The vacuuming is powerful and consistent, picking up everything from fine dust to larger debris without missing a beat. The navigation is smart and efficient—it maps your home quickly and cleans in a logical pattern instead of bouncing around randomly. You can tell right away this is a premium product designed to actually work, not just look good.
Where this system really separates itself is the mopping and water management setup. The dual water tank system—with a dedicated fresh water tank and a gray water tank—is a game changer. It constantly uses clean water to mop your floors and then separates out the dirty water, so you’re never just spreading grime around. The HydroJet™ system keeps the mop clean while it’s running, and the results speak for themselves—floors come out spotless, with a true “just cleaned” feel every time.
The added features take it to another level. The air freshener integration is a small touch that makes a big difference—it leaves your home smelling clean, not just looking clean. It’s those kinds of details that show how much thought went into this product. Everything works together seamlessly, from the self-emptying dustbin to the mop washing and drying system. You really don’t have to do much at all—just let it run and it handles the rest.
Another thing I appreciate is how quiet and refined it is. Even with all this power, it operates smoothly without being disruptive. You can run it during the day, at night, or while you’re home without it getting in the way.
And then there’s the value. Yes, it’s an investment—but when you consider everything it does, it’s absolutely worth the money. You’re saving time, effort, and honestly a lot of stress. Coming home to clean floors every day without lifting a finger is something you quickly get used to.
On top of that, eufy’s customer service is top-notch. That really matters when you’re buying something like this. Knowing the company stands behind their product and is there to help if you need anything gives you extra confidence in the purchase. It feels like you’re getting not just a product, but a full support system behind it.
Overall, this is a dream team in one machine—powerful vacuuming, advanced mopping, smart features, and thoughtful extras like the air freshener and dual water tanks. If you’re looking for the best of the best in home cleaning automation, this is it. Highly recommended.

My house has never been so clean!
Size: 05-11S
As a neat freak, this has been one of my favorite purchases recently. Hands down. No doubt. Our house has seriously never felt so clean. With four boys coming and going, plus a cat, plus my wife and I both working out of the same house, this place gets dir-r-r-r-ty! But now, I just set this little baby up and get it goes to town.
Note: the first several times that we used it, the machine's debris holding chamber was LOADED. We ran it until the battery died (and it returned to it's charger automatically), emptied it, and then ran it again as soon as it was fully charged. But each time that it ran, it was completely full! Every single time. None of us can believe how dirty we were living.
Note #2: We now take it upstairs to do a deep cleaning there. We had a little bit of a learning curve to make sure that all of the electric cords and such were off the floor. (They untangle easily, btw, if you forget). My son with the cat had a room that used to smell terrible... it smells almost normal after we ran this several times through there. And the volume of cat hair that this thing picked up is crazy amazing. Hair that we didn't even see. I didn't know cat hair smalled badly, but it must've. Room smells pretty decent now (not perfect - there still is a smally boy living in there)!
Note #3: We keep a pretty clean house. That is what is amazing about this thing. It makes it really clean.
Note #4: After the first several runs, make sure that you clean the roller brush. It will make a difference. The tool that comes with the unit that looks like a comb does a great job. If you get hair or thread or similar wrapped around it, use the handy dandy letter opener-style cutter to easily and safely clean it out. The blue parts on bottom around roller remove easily for deep cleaning. Do it! Easy and worth it for better future results.
Note #5: Does all types of floors really well. We have ceramic, vinyl, short carpet, marble, deep carpet - all on the first floor of our house --- NO PROBLEM for Eufy! It moves with ease between them all.
Note #6: Problem areas? We have a screened in porch that has a door that allows tiny little leaves in under the door. I'll just set the Eufy out there and forget about it. When I see it again, the machine has run out of juice and the floor is perfectly clean. Or my basement office. Set it in there at the end of the day, close the door and forget about it. In the morning, the floors are clean and the machine is sleeping where it ran out of power. I take it back upstairs, empty the cannister, and put it back on the charger.
Last note: It gets in tight spaces. It cleans edges beautifully. It spends more time on a room than we ever would, so I guess that is why it cleans so well. It gets under most of our furniture. Around most of our chairs. And oh - I almost forgot - this vacuum is SO-o-o-o quiet. With our upright, you can't hear yourself think. With this thing, I can be do my work uninterrupted.
Disclaimer - I have wasted a lot of time just watching machine in amazement and awe! Thankfully I can now walk away from it - although the 7 sessions with a therapist to get me to break the habit were a pain. ;)
I highly recommend the machine - if you couldn't already tell! I came back on to Amazon to buy a unit for my in-laws and saw the opportunity to avoid my job for a little bit to write this review! Funny, but I am glad that I did. This little fella is totally worth it. If you are thinking about which brand to buy, you can't go wrong with Eufy.
Kudos to the manufacturer and development team!
Note to manufacturer: Can you please develop a machine to automatically climb and clean stairs (cook, do toilets, do laundry)... ?
People, you are going to love this vacuum!

Great robovac! We named ours “Robby the Robovac.”
Size: 06-15C Max
I hesitated for years to pull the trigger on getting a robot vacuum, and I shouldn’t have. If you are on the fence, get one. This thing has been worth the $250 in the first month, alone. (I compare it to a maid service fee.) It automates the simplest but most essential task of cleaning, because most dust and dirt ends up on the floor. It also forced me to finally tidy up all the wires and miscellaneous junk I had laying around on the floor, and thereby also eliminate areas where dust and dirt would accumulate, both of which were unexpected side benefits. It also frees up time to then wet mop and clean other places more easily, and tacitly helps me WANT to follow through with those final stages of cleaning that are easier because it takes care of the most time-intensive, initial stage of cleaning.
It has been a life changer for us. The first week made the house smell a bit dusty because it kicked up all the latent dust from the corners, under furniture, and in the rugs. But once it got through that stage, the whole house looks and “feels” so much cleaner and smells nicer. Subtle but significant difference.
I live in a one-story bungalow with mostly hardwoood or laminate floors, with a low-nap Berber floor covering in my master bedroom. I have a mid-size wire-hair dog who sheds normally, and it is perfect for picking up dog hair. I also have a nine year old son who adds to the dust and dirt. The suction is great on all of our surfaces. It works better than my stand-up “cyclonic” Hoover. Having three suction settings allows you to adjust the noise level depending on how clean you need the suction to be. The side brushes seem trite but definitely do work to help collect and”funnel” dirt into the collection bin. They also hit under furniture legs and walls edges to help collect the dirt that hides there.
The collection bin does need to be emptied frequently (every few uses, especially when you first use it), but I look at that as letting me know what would have been on my floor if I didn’t have the unit. It is amazing how much it cleans off the floor even after the first wave of cleaning.
The different cleaning modes are also well thought out: edge cleaning, spiral-spot cleaning, and random walk cleaning. I use the edge cleaning mode the most because dust and dirt tend to congregate along the edges.
Three downsides that are probably fixed in higher end models. First, getting the app to work was unnecessarily frustrating and difficult because I forgot my exact WiFi password. The problem is that the interface requires you to go through about a five minute process for each “guess,” which made syncing to the app much more frustrating and unnecessarily slower than it should have been. Then with each failed attempt, I also had to also manually reset the entire unit by pressing the power button for 20 seconds. They should program it to test the password quickly so the entire syncing process does not take five minutes until you find out you typed the password incorrectly. (Especially because WiFi passwords are case-sensitive, so it is easy to mistype it). Once I typed the correct password and synced it, the problem was over, but it was frustrating and time consuming.
Second, controlling the unit manually through the app is difficult because of the lag time in the signal through WiFi. So any time I manually steer the until, I use the remote and not the app. Not a big deal, but something to note.
It is also too loud to schedule vacuuming at night. It woke us up the first three times it ran a scheduled overnight clean, partly because we keep our bedroom doors open at night. We are still on COVID lockdown, so I can’t just schedule it to run during the day while we are at work. So I just run it in the background during the day or when I leave to go to the store or take the dog for a walk.
Nonetheless, none of those are dealbreakers, mostly just minor inconveniences that are acceptable at this price point. It still earns its five star rating for fulfilling its primary purpose and then some.

Life Changing, and Superb Customer Service
Size: 12, Size: 12
Hey folks. I bought this model of Eufy while on sale a little over six months ago, and have used it daily since. Thinking about buying one? Do it. No regrets here, and I wish I had purchased one when I first began thinking about it a year and a half ago.
I live next to the Gulf Coast in Florida, and coastal living = constant sand. Fine, white quartz sand ends up in your home constantly regardless of how many rugs and floor mats you place at entranceways. Our home is completely tiled, and the powdery sand sticks to everything, so it’s a never ending battle keeping the floors clean. We used to sweep pretty much daily in the morning, and then use a hand vac around corners in the evening just to keep up with it. We also have one cat, a Great Pyrenees, and an English shepherd, so sweeping daily was necessary to keep fur from drifting into giant globs in corners and under furniture.
After purchasing the Eufy, and charging it up, we no longer have to sweep every day. The eufy is simply fantastic at getting up all the pet fur and sand. Instead of sweeping every morning, I now stare off vacantly out the window while drinking my coffee, and the eufy sweeps for me.
My five year old named our Eufy “Mumford” and we created a face cut out from a roll of white window cling vinyl (purchased the white vinyl window cling on amazon too- it’s meant for those Cricut machines) for the little guy. Mumford is now a treasured family member.
For reference, my house is all tile and is about 1500 square feet. The eufy can clean our dining room, living room, kitchen, bathroom, and playroom on a single charge, but since it doesn’t map out the rooms, I do place it in one room at a time, and block it off or shut the door. It does fine if I don’t block it off, but takes longer to get the job done. Since I keep the common areas clutter free, it is no trouble running the eufy every morning. I have my kiddos pick up anything on the floor, and then we hit the button and go about getting breakfast ready. If you are messier, or have a lot of clutter in your home- a Eufy probably isn’t the answer. It can’t do a good job if it isn’t able to roam around freely to vacuum.
It fits under all of our furniture, and maneuvers well around my oak dining tables and chairs.
If your home is very large and multi level, and you don’t want to pay attention - you may want something that maps your home. Eufy bumps around haphazardly, and when you leave it on long enough and run it consistently, it does a great job. I do not run it when we aren’t home, and I do not run it at night when we are sleeping. The last thing I want is for one of the dogs or the cat to get sick, and then have eufy run over the mess. Eeew. If you have pets, don’t make that mistake.
If your home is larger than 1500 square feet, you’ll likely have to clean different sections at a time maybe on different days or nights of the week.
Customer service is fantastic. After six months of daily use, our unit had a malfunction. The bumper on the right side would stick, and our unit would spin constantly clockwise. I contacted Eufy, and they did some troubleshooting with me, and when that didn’t fix the problem, I was sent a brand new unit. They emailed me a free return label to ship my old one back to them at no charge.
All in all this is an excellent and helpful product, and the company that makes it is reliable and true to the warranty. I know several people that own one and love it, and have recommended it to friends and family members.
Buy one!!!!!!

Cleans so you don't have to... QUIETLY
Size: 07-C30
I previously bought a Deebot for use on our main level floor, where we spend most of our time at home. It works great and connects with our Google Home. But we run it in the middle of the weekdays because it's pretty noisy. Still, we really like the benefits of a robotic vacuum. So, we thought we might try it on our lower level. I set it up downstairs, but found that, while it seemed to pick up dirt, the back end bounced quite a bit over the berber carpet, which isn't an issue on the main floor which is hardwood with only one entry rug.
So, we went about looking for an alternative for downstairs. We really wanted something that can connect with our Google Home, so that limited our options within our budget. There were lots of great reviews of iRobot products for carpet, but I had a hard time with the price. There were a few other brands, as well, but they were obscure brands, and I didn't want to be stuck with an expensive vacuum and no customer service.
Eufy was a brand I kept in mind as I shopped because we'd had a lot of experience with their parent brand, Anker. They've always sold us a great product at a reasonable price, and importantly, if a product failed for any reason, we'd experienced great customer service. I finally decided I'd pull the trigger on the RoboVac 30C because it had the features we wanted.
I ordered it from Amazon on Thanksgiving with a bunch of other stuff I wanted to get. I was a bit disappointed that there was no Black Friday pricing, but it was still very competitive over the deeply discounted Roomba models *(see below).
It arrived on Sunday, so very quick shipping via Amazon Prime. We set it up right away. The first, VERY OBVIOUS thing we noticed... It's quiet* (see below). Way quieter than the Deebot. As we had hoped, it also picked up dirt from the carpet easily and without bouncing.
The magnetic strips also helped to avoid another pitfall of the Deebot... We have these chairs with unusual bases that are low enough on the edges for the vacuums to drive themselves up on, then there's a hole about 3 inches from the edge that creates a cliff for the vacuum to get hung up on. Both vacuums will do that, but the Eufy 30C has those strips which it won't cross. Put the strips around the base of the chairs, and no hangups.
The only issue right now is that, unfortunately, the Eufy app doesn't play with Google Home very well. We are assuming that will get fixed. And if it doesn't, the app works pretty well as a stand alone, which is the next best thing, so I won't dock any stars for that.
Overall, I am extremely pleased with this vacuum so far. It does clean very well and doesn't have any problem doing approximately 400 square feet on a single charge around furniture and other odds and ends on the floor.
*Customer service : Many vendors will contact Amazon customers shortly after purchase of one of their products to make sure all is well. Eufy did this. I thought I'd give them a preliminary review because I wanted to let them know that things were going well so far. I mentioned that it worked great (didn't know about the Google home issue, yet, but I was overall pleased). I mentioned as an aside that it was a tiny bit annoying that it arrived on Sunday and the Cyber Monday deal made a significant price difference. Still, I liked it enough that I wasn't going to be too annoyed. I certainly wasn't going to try to return it and buy it again to get the better price. A couple days later, they thanked me for my comments... And refunded me the difference in price. They definitely didn't have to. But it was pretty awesome of them.
*Noise level: My hubby set up the schedule for the RoboVac 30C. He decided to go with the same schedule as the Deebot, on Monday, Wednesday, and Friday in the middle of the day. But instead of setting it up for 12:01 pm, he set it for am. It was running in the middle of the night and we didn't know it for 2+ weeks. I discovered it when I decided to make sure to have the app on my phone too and saw the scheduling error. To be fair, we sleep on the upper level of our modified split level house and the RoboVac is on the lower level, but I have ears like a bat, and had no idea. And yes, it's cleaning - - I've been cleaning out the dust bin for it regularly. Definitely wouldn't have been that way with the Deebot. So, yeah. It's quiet.
