The Roborock Saros 10R aces one thing that most other robot vacuums cant
The Roborock Saros 10R is one of the slimmest and most powerful robot vacuums out there in 2025. I tested it at home for a month right after its CES debut.
The robot vacuum with a grabby arm from Roborock's showing at CES 2025 has been hogging all of the attention, but that one wasn't the new Roborock vacuum that I wanted to test the most.
Though I'll still get my hands on the Roborock Saros Z70 at some point, I was personally more interested in the Roborock Saros 10R: a way more practical robot vacuum from the 2025 fleet that still goes hard on premium upgrades.
What's special about the Roborock Saros 10R?
As Roborock's thinnest robot vacuum ever, the Roborock Saros 10R may not seem like it has room for a big navigational tech upgrade — or Roborock's second-most powerful suction power yet. But somehow, both of those are packed into a body that's barely more than three inches tall.
The Saros 10R clocks 20,000 Pa of suction power, only to be beaten by its sibling, the Saros 10's 22,000 Pa. Still, 20,000 Pa is a level that very few other robot vacs in the market even come close to. To put it in perspective, that's double the whoosh of my favorite robot vacuum from 2024, the Roborock Qrevo Master.
The other main grab here applies to how perceptive the vac is as it's maneuvering around your home. Compared to the typical LiDAR system, the Saros 10R axes the circular laser tower atop most robot vacs you're probably picturing. Instead, the Saros 10R is able to have that thin, flat top design due to its implementation of StarSight 2.0 with 3D ToF (Time of Flight) technology. That's some fancy NASA-coded terminology for a more precise sense of location within your walls and more precise detection of small objects.
Rather than just relying on laser sensors as traditional LiDAR does, StarSight takes it a step further with 3D scanning of 21,600 sensor points around the room. With that, the Saros 10R can sniff out upwards of 108 different objects (that's up from the 73 objects that the first version of Starsight could detect). With the upgrade to the 2.0 version also comes Vertibeam Lateral Obstacle Avoidance to aid in delicately cleaning around irregular walls and furniture.
Now, this isn't the first time we've seen StarSight 2.0 — the 2024 Roborock Qrevo Slim also uses it. But the Qrevo Slim's 11,000 Pa of suction power pales in comparison to the Saros 10R's 20,000 Pa. Another Saros model, the Saros Z70, also has StarSight 2.0 technology, but it's expected to cost around $2,000 when it finally comes out. So impressively, the Saros 10R is the only StarSight model that hits 20,000 Pa without hitting the $2,000 price point.
Also, a little commotion for the Saros 10R's chic dock, please.
After years of testing robot vacuums that basically strictly exist in plasticky black or plasticky white designs, this dock's sleek mirrored face with rounded corners is a welcomed glow-up. (The fingerprints it easily attracts? Slightly less chic.) I still fully stand by my formal plea for robot vacuums to start coming in chrome gray to match stainless steel kitchen appliances, but I digress — the Roborock Saros 10R is a self-emptying dock you won't mind sitting out in your living room. At 19 inches tall x 15 inches wide x 12 inches deep, it's also on the compact side — it's smaller than Dreame X50 Ultra and Roborock Qrevo Master's docks.
Cleaning performance: Mopping and corner cleaning are the standouts
I want to talk about the 20,000 Pa of suction power first. On paper, that's the strongest robot vacuum I've had under my roof to date — incredible news for a person with barefoot standards as high as mine.
The suction power bump was most palpable when simply taking care of everyday debris that keeps me up at night if not cleaned: crumbs and rogue pieces of shredded cheese near the kitchen counter, kibble near the cat food bowls, kitty litter spread in a two-foot radius around both litter boxes, and strands of long hair everywhere. I sent the Saros 10R to tidy all of this on a daily basis (occasionally twice a day) and was almost always welcomed back into a pretty spotless room. The cleaning was incredibly consistent on dry debris of various sizes and textures, and I wasn't constantly feeling like using the robot vacuum was just a Band-Aid until I had time to actually go in with my trusty Dyson V12 Detect Slim.
Speaking of my Dyson, I will use its green laser to prove a point about the Saros 10R's competency on kitty litter (or any other small, crunchy remnants that will probably pop up in most people's homes).
Coverage on rugs was slightly more hit-or-miss than on hardwood or tile. The Saros 10R had about a 90 percent pickup rate on my medium-pile rugs, taking care of spilled chip crumbs and full Goldfish crackers, layers of shedding from my two cats, and long hair that I pulled directly out of my brush and threw on the floor (for science).
Unfortunately, the pickup percentage dwindled a bit on lower pile rugs. My cats sunbathe on the one in my room on a daily basis, so it's usually covered in a layer of cat hair not super visible unless you look at the bottom of your socks. One surefire way I can see how well a robot vacuum is doing on pet hair is to use my Shark PowerDetect stick vacuum afterward. The key here is that that Shark self-empties its dustbin into a larger dock each time I hang it back up, which means it's always starting with a completely empty, clear dustbin — and that means I can quickly pinpoint just how much gunk is being sucked up during the cleaning session at hand.
That Shark's dustbin should just not be that full after a robot vacuum dished out 20,000 Pa of suction power across it. Granted, I will say that I also did the Shark test on that gray rug a few paragraphs up, and the Saros 10R had clearly done a much more thorough job there. Higher pile is typically the trickier length for robot vacuums to comb through, but oddly enough, it seems backwards for the Saros 10R — I'm not sure if that has something to do with the side-by-side brushrolls versus the typically parallel ones or what.
This edge cleaning absolutely eats
I will say, though, that I'm not super mad about the mediocrity on low pile rugs because of how the Saros 10R aced one problem area that robot vacs always seem to struggle with: corner cleaning. Aside from heightened suction power all around, that level of detail in right angles and along edges can likely be attributed to both the flexible corner arms and upgraded StarSight that allows the bot to better assess walls, furniture, objects, and how close it can get to them.
More impressively, the close corner cleaning also applies to mopping. Robot mops that only have one large, mostly stationary singular pad just don't have much range of motion, whereas the side-by-side spinning mopping pads on the Saros 10R do. One swings on a hinge and extends out from under the robot vacuum to hit edges and 90-degree angles that a circular vacuum would fumble otherwise.
This is another crucial factor for the picky barefoot crowd who need to know a floor is actually being scrubbed from multiple angles. In my experience, the dual spinning design just provides more versatile physical agitation to thoroughly scrub at stains or wipe up stickiness — the big singular pad just feels like a glorified once-over with a washcloth.
I had no complaints about the Saros 10R's mopping performance on thin consistences like wine and soy sauce spills. Thicker drops like ranch and marinara sauce did risk getting pushed around before the Saros 10R had a chance to return to the dock to wash the pads, but overall, remnants weren't really left behind. Syrup was a struggle — the area around the original syrup incident was slightly sticky and smelled like syrup before I cleaned it by hand. Two cleaning passes are probably necessary for thicker, peskier spills like that.
Automated mopping with actually good edge mopping has really come in handy for random droplets under the kitchen counter and for the upkeep of our front door situation. Usually, there are two stools plus a million pairs of shoes piled up under this island, and the whole area is just constantly covered in footprints, little rocks, hair, and other stuff like that. It's been nice to simply push everything out of the way, let the Saros 10R get all up in there, and then put everything back. It was particularly delicious to watch the Saros 10R successfully lap up the visible dust, crumbs, and hair that gather under that edge that a stick vacuum is too thick to reach.
But I think my favorite example of the Saros 10R's cleaning exhaustiveness comes when it has to vacuum and mop at the same time — for certain messes, that'll only go well if both parts are doing their job well. For instance, I decided to re-pot a snake plant (IDK what I did to kill it, don't come for me) in the middle of my living room. I made an absolute mess of moist potting soil on the hardwood, then sent the Saros 10R to vacuum and mop it at the same time. Just vacuuming would still leave a brown dusty film that isn't really the consistency to be sucked up, but just mopping would just turn that dirt into mud.
I was seriously impressed at how spotless that area was after the Saros 10R came through. I did send it for two passes because I assumed it'd miss some pieces the first time. The second trip covered any lingering pieces on the outskirts of the zone, with the mopping pads coming through and eliminating that brown dusty film. A cheap Roomba trying to tackle a pile of dirt would literally just make the mess bigger.
Navigation: Gets to the right spot without question
The few minutes that it took to unbox and set up the Saros 10R took longer than the Saros 10R did to complete its first mapping run of my apartment. That speediness didn't dog its accuracy — a majority of its room designations were correct, complete with notches already marked for large obstacles like turns in the wall or big pieces of furniture. All I had to do was drag some lines to split the very open-concept kitchen, living room, and entryway up. (The fact that the app has a room limit is weird, but OK.)
During over a month of testing and use multiple times a day, the Saros 10R literally never got lost. I was almost always either doing a specific room or zone cleaning (rather than letting a full home cleaning rip), and I never had to give a second thought to whether it'd make it to the right spot, whether it'd actually cover the entire selected area, or whether it'd take extra long going on side missions that I didn't assign.
There wasn't really any getting stuck, either. The Saros 10R carefully weaved in and out of various table and chair legs, around cat food and water bowls, and under a bed with a chaotic storage situation underneath. My bathroom layout is a little tight, with a toilet, a litter box, and an egg-shaped hamper, and many robot vacuums give up instead of cleaning in between all of that stuff. The Saros 10R carved around all of them safely, even picking up most hairs and kitty litter by the wall.
Past smart mapping, small obstacle avoidance is the other factor playing into a robot vacuum's navigation. It's definitely a crucial feature to have if there are cords or other random crap on the floor from time to time. While the Saros 10R's track record was good in my apartment, there were still some blips on small cat toys, one charger, and wiry string lights dangling on the floor. I don't expect perfection even from a top Roomba (my most trusted small obstacle avoidance tech), but I'm not sure that the whole StarSight upgrade is any more accurate than traditional LiDAR.
User-friendliness: A relatively quiet, pet-friendly addition to your home
Volume during cleaning obviously varies based on the suction level, which gets up to 68 decibels on max. I was impressed by how unobtrusive the automatic emptying whoosh is — around 73 decibels, which is a similar level to the rumble of a washing machine. It's much more muffled than I'm used to and does not scare the shit out of me every time.
If you have pets, the Saros 10R's livestream pet camera is yet another feature that helps this vacuum blend in with your home life. Like some older flagship Roborocks, the camera tab in the app allows you to see whatever the robot sees as it's driving, including an option to "search for the pet."
Is it a completely necessary feature? Probably not. But if you're a pet parent and you say you wouldn't use this, you're lying. A ton of people have standalone security cameras to keep tabs on their pets when they're not home, so adding that pet sitter-like feature to an appliance that's already roving your house is actually pretty practical.
Maintenance: Hands-off and competent, as expected
As expected from any top robot vacuum brand's premium models nowadays, the Saros 10R comes with a full self-cleaning dock that includes automatic dustbin emptying and automatic mopping pad washing and heated drying, as well as water tank refilling.
I personally find the autonomous mopping pad maintenance system to be so worth it if you, well, actually want to use the mop on a regular basis. When testing mopping robot vacuums that don't have the auto wash and dry system, I found myself not using mopping mode simply because I didn't feel like dealing with washing a soggy mopping pad every day. The Saros 10R made that part super easy and, as with most self-cleaning docks, also maintained its mops during mopping by returning to rinse them mid-clean.
One tiny thing I've noticed is that it feels like the clean water tank is always empty or the dirty water tank is always full. The tanks are definitely smaller than others in self-cleaning docks that I've seen, probably to keep the dock compact. Granted, I do send the Saros 10R out to mop a lot — my large 22-foot x 10-foot hardwood kitchen gets mopped almost every day, and my tile bathroom and the apartment entryway get it about every other day. The red light to refill the clean water tank comes on once every few days. Though it's more often than most of the robot vacs I've tested in the past, it's not outlandish. Plus, the dirty water is pretty damn gross every time I dump it, and that's just proof that the vac's scrubbing thoroughly. And when a robot mop is so reliable that building it into a daily routine becomes a reflex, more frequent refilling just comes with the territory.
When it comes to maintaining the brush roll, the Saros 10R doesn't really require regular upkeep of tangled hair. This is thanks to its side-by-side DuoDivide brush rolls that spin independently and pull hair toward the middle and up into the dustbin. After about two weeks of using the Saros 10R every day, I got my scissors out, expecting to need to cut some wrapped hairballs out of the bottom. To my surprise, next to no hair was wrapped around, marking the first robot vacuum I've ever tried that actually follows through on its "anti-tangle" claims.
Downsides: A few quirks for being so expensive
The Roborock Saros 10R is one of the most expensive robot vacuums on the market in 2025. It is the norm for a brand's high-enders to near or topple the $1,500 price point, and the Saros 10R is quite advanced. Still, many people would probably laugh out loud at the thought of spending that much on a vacuum.
But FWIW, the $1,599.99 is actually quite modest when you consider that Roborock's most expensive flagship from 2024, the S8 MaxV Ultra, also debuted at $1,599.99. That vacuum only has 8,000 Pa of suction power (compared to 20,000) and obviously doesn't use the upgraded obstacle avoidance system that the Saros 10R does, yet debuted at the same price. So the Saros 10R gets credit there.
However, the argument could be made that a robot vacuum this expensive should operate pretty much perfectly, and the Saros 10R doesn't. Firstly, though the whole StarSight thing was supposed to be a big selling point, I'm not sure if it's necessarily better than other small obstacle avoidance tech out there, like Roborock's Reactive AI or iRobot's camera-based PrecisionVision navigation. My Saros 10R did run over some cat toys and a white phone charger once (granted, it was kind of blending in with a rug with white swirls) and completely ate a wiry string of twinkle lights. Even the smartest botvacs are bound to slip up every once in a while, but still.
The clean water tank draining and the dirty water tank filling "quickly" can't even fully be classified as a downside, in my opinion, because I do think it's a testament to how often I'm opting to have this thing mop. For the price, I do think the Saros 10R should automatically dispense detergent into the clean water tank from inside the dock.
It's also possible that the water runs out so often because the Saros 10R takes forever to mop. Surely it's expending more water than necessary. It's not typically an issue unless I'm in a hurry for whatever reason, but sometimes, I'm like, "PLEASE be done soon."
One other minor thing about the dock is that the auto-empty suction doesn't always "work" the whole way. I frequently see a dust bunny hanging out the back of the robot vacuum itself where it connects to the dock. That's not a huge deal.
And while I don't expect every dock to be front accessible so that the top can be used like a side table (like the Roomba Combo Max 10), I do like when the water buckets are flat so that I can at least set decor on them that can be moved when the tanks need to be refilled.
The competition
Overall, it just makes the most sense to simply pit the Saros 10R against other robot vacuums in the same price range. The main competitor is the Roborock Saros 10 (no R), named nearly identically for reasons unbeknownst to man. (Roborock did the same thing with the million Qrevo models from last year.) While the Saros 10 does squeeze out 2,000 Pa more suction power than the 10R, that's a negligible difference when you're already at 20,000. The mopping pad setup would be my main deciding factor, as I've witnessed more thorough results from a dual spinning pad design (like the 10R's) over the outdated, singular D-shaped pad (like the Saros 10's) that can't really scootch out from under the vacuum into corners. I'll keep you posted on whether the regular Saros 10's Reactive AI obstacle avoidance is any better or worse than the 10R's StarSight.
For a cheaper-but-still-top-notch Roborock pick, I still think the Qrevo Master would be excellent in most households. Though it has half the suction power as the Saros 10R, its 10,000 Pa still fared well in my apartment. It has the same spinning mopping pads, self-cleaning dock, and pet camera, and is frequently on sale for as low as $899.99.
The other Saros model dropped at CES 2025 was the Z70, but the difference between the Saros 10R and the Saros Z70 is easier to spot: one has an arm, and one doesn't. While it sounds cool upon first read, the Saros Z70's practicality dwindles quickly when you learn that it'll probably cost around $2,000 for cleaning capabilities not much more powerful than the 10R. The Saros 10R certainly isn't about to be running over little items any more than the Z10 is — it just won't be putting them in a nearby basket. In the words of my fellow Senior Shopping Reporter Haley Henschel, if you can afford a $2,000 robot vacuum with an arm, "why not just hire a maid?"
In terms of non-Roborock models, iRobot's best fighter would be the Roomba Combo 10 Max. It's the only Roomba that washes and dries its mopping pads and refills its own water tank, and could be a good bit more affordable than the Saros 10R if you can find it on sale for $899 or $999. While I'm slightly more confident in iRobot's obstacle avoidance, the Combo 10 Max kept missing debris along edges and in corners of my apartment. It also uses a singular flat mop pad that doesn't cover a lot of ground on one pass.
The Saros 10R's biggest competition from the class of CES 2025 is the $1,699.99 Dreame X50 Ultra, whose claim to fame is climbing — over small obstacles and thresholds, not up and down stairs. Like my take on the robotic arm thing, I personally don't care about these fancier physical methods of avoiding obstacles as long as nothing is being eaten. Despite matching 20,000 Pa suction power, the X50 Ultra I'm testing has left some rolled-up hairballs and fuzzies on more of my rugs than the 10R has. It also has a plasticky build and a not-so-compact dock.
Is the Roborock Saros 10R worth it?
When it costs $1,600, a botvac like the Roborock Saros 10R should be completing damn near every single task flawlessly. I'm not going to sit here and tell you that it does.
But I still think the Saros 10R is a wickedly well-rounded robot vacuum that would be a totally satisfactory upgrade in a lot of homes, especially ones with a lot of hard floors. Its suction power and mopping work together in tandem to achieve results more reliable than what I've ever experienced, even if its work on low pile rugs hasn't been as exceptional as I'd expect for a premium vac. If you've been frustrated specifically with corner cleaning, scrubbing, or low-clearance furniture with other vacuums, I'd say the Saros 10R will piss you off way less.
But would I wait for the verdict on the other blockbuster CES 2025 robot vacuums, or the verdict on one of the fancier Roombas that were just announced. If you still decide to go for the Saros 10R, that'll at least give you time to wait for a sale.
