Roborock Saros 20 review.

The coverage champion that's scared of your dining chairs

CNET's lab maps where each robot actually drives with a heat-map test, and the Saros 20 reached 88.65% of the test room. That earned it CNET's Lab Test award for best cleaning coverage in April, ahead of the Dreame X50 Ultra that held it before. Vacuum Wars then watched it climb a 57 mm single step, the tallest that site has recorded. On paper, this is the robot that gets everywhere.

Now go and read the owner forums. Over the last month the Saros 20 has drawn more Reddit discussion than any other new robot vacuum, and a lot of it is about the places it won't go: the gap between dining chairs, the patch under a nightstand, the cat toy it should have steered around. Both stories are true, and which one matters depends on your floor.

The Saros 20 is Roborock's 2026 flagship robot vacuum and mop, launched at CES in January and on sale in North America since March. In Canada it's $2,299.99 at Roborock's own store and on Amazon.ca (checked October 13, 2026), against a US list price of US$1,599.99. This review answers one question: is it worth that much for a Canadian home, and what kind of home?

What's actually new over the Saros 10R, and the Saros 20 you don't want by mistake

The Saros 20 replaces the Saros 10R, the version without a lidar turret on top. It keeps that flat, puck-free shape and the front-facing StarSight sensors, now in a 2.0 version Roborock says recognizes more than 300 kinds of objects. The big upgrades are suction, up from 22,000 Pa to a claimed 36,000 Pa, the AdaptiLift 3.0 chassis that lifts the whole robot over steps and hovers it over deep rugs, and a dock that washes mop pads in boiling water and dries the dust bag after every run.

Roborock's naming makes this harder than it should be. The Saros 20 Sonic is a different robot: it follows the Saros 10, with a lidar turret that pops up and down and a single vibrating mop pad instead of two spinning ones. Vacuum Wars tested both, and the Sonic scored 15.8 on mopping to the standard model's 25.2. There's also a Saros 20 Flow with a roller mop and a Saros 20 Neo, which is sold as the Qrevo Edge 3 Pro in the US. Check the exact name before you pay.

Who shouldn't upgrade? Anyone with a working Saros 10 or 10R. The Ambient put it plainly: the Saros 20 refines last year's flagships rather than reinventing them, and owners of either have little reason to switch. The upgrade makes sense from something four or five years old, or if your current robot can't get over a sill.

It climbs steps rivals can't, but not always gracefully

Roborock rates the Saros 20 for single door sills up to 4.5 cm and double-layer steps up to 8.8 cm, split into a 4.5 cm and a 4.3 cm tier. The fine print matters: that double-step figure comes from Roborock's own testing with a gap of 12 to 14 cm between the two tiers. The robot pushes its wheels down, raises extra legs and, as TechRadar watched, backs up, lifts its nose and takes a run at it.

The outside results are good but mixed. Vacuum Wars measured that 57 mm record single step. TechRadar said it hesitated at first on a chunky laminate-to-carpet transition, then learned to cross it. GearBrain's tester, after several months, found it sometimes struggled or got stuck on a 3.84 cm radiant-floor kitchen transition, a reminder that a step's shape and angle matter as much as its height. The Ambient's Victorian kitchen step was simply too tall.

Owners describe the same split. Videos from homes with tall Danish-style sills show it getting over by throwing itself at the step, and the comments under them are full of people wincing. A few owners with home-made ramps found it aborts with a path error halfway up, while a Qrevo Curv or a Dreame X60 in the same spot coped. If you have a sunken living room or old-house sills, this is still one of the best climbers you can buy. Just expect some trial and error.

The vacuuming numbers: great on carpet and hair, ordinary on the bench

Pascal ratings sell robots, but they don't predict pickup. Vacuum Wars' bench test measured below-average airflow and sealed suction for the Saros 20, yet in its real-floor tests the robot pulled 89% of embedded sand from carpet (the average is 78%) and 88% of flattened pet hair (average 82%). CNET's lab found it extracted 82.48% of sand from hardwood and 28.99% from midpile carpet. That midpile number sounds low, but it's better than most robots CNET has run and close to its overall pick, the Roomba Combo 10 Max.

Pet hair is where reviewers sound most impressed. TechRadar ground a fistful of dog-hair clippings into a carpet and found it almost entirely gone after four passes on maximum settings, a job that usually needs an upright vacuum. The Ambient said two passes at full power with carpet boost cleared all the flour from its test rug. Gizmodo's hard-floor debris test, with dried spaghetti, shells and spices, left only a couple of pistachio shells and an Altoid, which it got on the second pass.

The split DuoDivide brush earned a perfect score in Vacuum Wars' 7-inch hair test, with nothing wrapped. Edges are good, not perfect. The side brush swings out to reach walls, but TechRadar still needed a crevice tool for oats tucked against a skirting board. If carpet and hair are your main problems, this is a top-tier vacuum. If your floors are mostly hard and lightly used, you're paying for power you won't notice.

Two spinning pads and a boiling-water dock: how good is the mopping?

Spinning pads are the older mopping design, and roller mops get most of the hype in 2026. The Saros 20 still holds its own. Vacuum Wars scored its mopping at 25.2 against a 20.3 average, with dried coffee removal well above the pack. The Ambient saw coffee and red wine vanish in one pass. One pad swings out on an arm to reach edges, and the robot can press the pads down with up to 13 N of force on stubborn marks.

Sticky messes are a different story. TechRadar's honey test and Gizmodo's dried barbecue sauce both needed a second pass, and some still needed a cloth. Tech Advisor found dried sauce only fully lifted on the deepest setting. That's the limit of pads that only get rinsed at the dock: between washes they partly move the mess around. A few owners coming from older Roborocks with vibrating pads say those mopped better, though Vacuum Wars' numbers point the other way.

The dock is the real upgrade. It washes the pads in 100 °C water, dries them with 55 °C air, dries the dust bag so it doesn't go musty, and drops the pads off entirely for vacuum-only runs. TechRadar's pads came out of a honey-and-soy-sauce cleanup clean and odour-free. Two small annoyances: the side brush doesn't lift while mopping, so it can spin through a spill, and the bag-drying cycle adds a low hum after each run.

The weak spot: cords, cat toys and the gap between chairs

Roborock says the Saros 20 recognizes more than 300 kinds of objects. Independent results are less flattering. CNET's lab ran its obstacle course three times and the robot avoided three or four of six objects on average, hitting the simulated pet waste more than once. Vacuum Wars scored it 17 of 24, a touch above its average, though the Saros 20 Sonic did slightly better at 19. Tech Advisor saw it swallow cat toys and curtain threads, and Gizmodo watched it eat a USB-C cable on a patterned rug.

Owners report the same thing more bluntly. Across r/Roborock and r/RobotVacuums, a recurring complaint is a robot that photographs a sock or cat toy, pauses, and drives over it anyway, even on the most cautious setting. A few separate owners say it has run through pet accidents. Several others in the same threads say theirs marks cables and never touches them, so results vary a lot by home. The pattern is clear enough, though, that this isn't a robot to leave running unsupervised around a puppy.

The second complaint is subtler. A number of owners upgrading from an S8 say the Saros 20 refuses to clean between dining chairs or under bar stools it could physically fit through. One support reply shared on Reddit blamed a more sensitive bumper and suggested moving the chairs. Owners found a better workaround: let it photograph a chair, then turn off avoidance for that object type in that one area of the map.

What owners are saying after the first weeks

Read enough threads and the praise is consistent. Owners in long-haired families and homes with heavy-shedding dogs say the brush stays clean. People with low couches like that it gets underneath without the furniture risers older robots needed. Some who compared it with a Narwal at home say the Saros 20 got stuck less and fit under more furniture, even if the Narwal mopped better. Quiet running comes up a lot, which matches The Ambient's 58 dB reading and CNET's 57.58 dB.

The recurring problems are specific. Heavy pet hair can pack the small robot bin so tightly that the dock can't pull it out; the fix owners agree on is setting the dock to empty at the highest frequency and splitting cleaning into separate rooms. A September firmware update, version 02.57.88, left several owners with cliff-sensor errors on dark rugs and erratic driving, and some rolled back with a factory reset. Several US buyers were surprised the box had no detergent, and others noticed the dispenser uses only a few millilitres a wash, so a bottle lasts months.

Beyond that come one-off hardware faults: a snapped mop mount, a dripping refill valve, a wheel error at four months, a unit dead on day one. None of those is a pattern yet, but together they're a reason to buy somewhere with an easy return. The most common thing owners say they returned it for is a Dreame X60, and the most common reason is obstacle avoidance. There's no Canadian-specific pattern in the threads; complaints read the same here as in Europe and the US.

How it stacks up against what $2,300 buys in Canada

Prices checked October 13, 2026. The Narwal Flow 2 is $1,999.99 on Amazon.ca. CNET gave it its object-avoidance award after it dodged all six obstacles in every run, and owners say its roller mop cleans better, but CNET measured weaker midpile carpet pickup, and a few owners say it skips rooms or parts of the map. If clutter and mopping matter more than carpet, it's the better buy for less money.

The Dreame X60 Ultra kit is $1,779.99 at Best Buy Canada. It's the robot Saros 20 owners most often say they switched to, mostly for steadier obstacle avoidance and ramp handling. The older Dreame X50 Ultra is $1,259.99 there and climbs 6 cm steps, which covers most homes. Roborock's own Saros 10 is $1,099.99 at Best Buy Canada, less than half the Saros 20's price, with a pop-up lidar turret and a vibrating mop pad.

The Saros Z70, the one with the robotic arm, is $1,299.99 at Best Buy Canada and is more of a curiosity than a better cleaner. If your sills are ordinary and your rugs are thin, the Saros 10 at that price is the value pick. The Saros 20 only earns its premium when its climbing and carpet strengths solve a problem you actually have.

Living with it: running costs, warranty and the cross-border trap

Day to day, the dock does most of the work. You refill the 4 L clean tank and empty the 3.5 L dirty one, and The Ambient and Tech Advisor both estimate a dust bag lasts around 65 days. Roborock Canada sells a six-pack of bags for $46.99 and its floor cleaner for $27.99. On Amazon.ca a genuine DuoDivide main brush is $44.99 and a four-pack of Roborock mop pads is $62.99. Budget roughly $150 to $200 a year if you replace parts on schedule.

The warranty is where Canadians need to pay attention. Roborock Canada covers new robots for one year and takes returns within 30 days, but its terms say the warranty only applies to products officially sold in Canada and excludes anything bought or used outside the country. A US-bought Saros 20 might look like a deal at US prices, but you'd be on your own if it breaks.

Software is the other ownership cost. TechRadar called the app powerful but a lot for newcomers, PCWorld found multi-floor mapping buried several menus deep, and Tech Advisor found schedules defaulted to one-time runs that then vanished. GearBrain said Matter and Home Assistant settings were hard to find. Firmware updates fix things, but the September update shows they can also break them, so keep an eye on the forums before you accept one.

Buy it, skip it, or buy this instead

Buy the Saros 20 if your home fights robots: tall sills between rooms, thick rugs, low couches and beds, and long hair everywhere. That's where it beats nearly everything, and the boiling-water dock makes it close to hands-off. Wait for a sale, though. TechRadar's price tracker has shown it at CA$1,699.99 on Amazon.ca, and CNET lists it around US$1,195 in the US, so paying $2,299.99 is a poor trade.

Skip it if your floor is rarely clear. With a puppy that has accidents, a toddler's toy box or a tangle of chargers, the Narwal Flow 2 or a Dreame X60 Ultra will give you fewer bad mornings. Skip it too if you already own a Saros 10 or 10R, or if your sills are low enough that a $1,099.99 Saros 10 does the same job. Whatever you buy, get it from a Canadian retailer so the warranty applies.
