Roborock Saros vs Qrevo: Which Line Fits Your Floors

Roborock splits its current range into two families that overlap heavily on paper and diverge on one physical decision: what to do with the navigation turret. The Saros line hides or removes the lidar to get the chassis down to around three inches. The Qrevo line keeps a conventional turret and spends the height budget elsewhere. Almost every practical difference between the two follows from that, and price is not a reliable guide to which one suits a given house.

Saros versus Qrevo at a glance

Every figure below is published on the product page for that model, and prices are correct at the time of writing. Where a number is absent, the cell says so rather than borrowing from a sibling model.

Two things stand out. The height gap between the lines is close to a full inch, which is a genuine access difference rather than a styling one. And the pricing does not sort by family: the Qrevo Edge sits above every Saros model listed here.

Four questions that decide the line

How low is your lowest furniture? Measure the clearance under the sofa, the bed frame and the kitchen toe-kick before reading any other specification. A Saros model at 3.14 in gets under furniture that stops a 4.1 in Qrevo. If nothing in the house sits below about four and a half inches, the height advantage buys nothing and the money is better spent elsewhere.

How thick is the carpet? Where mop lift is published, the Saros models clear more: up to 22 mm on the Saros 10R and the Saros Z70, against AdaptiLift up to 10 mm on the Qrevo Edge. On plush pile that is the difference between a dry rug and a damp one.

Are you willing to plumb it? A refill and drainage dock deletes the two water chores that survive every other level of automation, at the cost of installing near a supply and a drain.

How long between interventions? Published hands-free intervals differ: up to 70 days on the Saros 10R, up to 60 days on the Saros Z70, up to 7 weeks on the Saros 10. The Qrevo pages do not publish an equivalent figure.

Thresholds, worth noting, are not the deciding axis. Both lines are quoted at up to 1.57 in (4 cm) on double-layer thresholds, so a house full of transition strips does not by itself push the decision either way.

The Saros 10R and Dock 4.0

The Roborock Saros 10R Robot Vacuum with Multifunctional Dock 4.0 takes the most aggressive approach to height: there is no lidar turret at all, and navigation runs on the StarSight Autonomous System 2.0. That gets the body to 3.14 in (79.8 mm) with no moving mast to fail.

Its 10-in-1 dock washes pads at 176 F (80 C), dries them at 131 F (55 C), self-cleans at 176 F (80 C), and holds a 20 oz (590 ml) detergent dispenser. Dust bag changes are quoted at up to 70 days, the longest interval in this comparison. Mops lift up to 0.87 in (22 mm), thresholds up to 1.57 in (4 cm) double-layer, and the battery is 6,400 mAh. It is $1,099.99. Roborock does not publish a suction figure for this model, so treat any number you see quoted elsewhere with suspicion.

Saros Z70 and the OmniGrip arm

The Roborock Saros Z70 Robot Vacuum with OmniGrip™ Mechanical Arm is the same low-profile platform with a foldable five-axis arm that lifts items up to 300 g and moves them out of the cleaning path. Socks and light cables are inside that limit; shoes and toys mostly are not.

The rest of the machine is conventional Saros: 22,000 Pa of suction, 3.14 in tall, mop lift up to 22 mm, thresholds up to 4 cm double-layer, a 6,400 mAh battery, and about 2 hours 15 minutes per charge with the arm disabled. Navigation is StarSight 2.0 with 3D sensing, recognising 108 obstacle types plus up to 50 user-defined objects, and the dock washes at 176 F (80 C) and dries at 131 F (55 C) with up to 60 days of dust capacity. At $999.99 it is the least expensive Saros here.

The Qrevo Curv line

Qrevo keeps a PreciSense LiDAR turret, and the 4.1 in height is the direct consequence. What that height buys is a more conventional and well-proven navigation stack. The Roborock Qrevo Curv Robot Vacuum with Multifunctional Dock 3.0 publishes 18,500 Pa of suction, a 6,400 mAh battery, a DuoDivide anti-tangle main brush with a FlexiArm arc side brush, and thresholds up to 1.18 in (3 cm) standard or 1.57 in (4 cm) double-layer. Its dock washes with 167 F (75 C) hot water and dries with warm air. At $849.99 it is the cheapest way into this class of brush and dock.

The Qrevo Edge flagship

Sitting at the top of the Qrevo range, the Roborock Qrevo Edge Robot Vacuum with Multifunctional Dock 3.0 (Upgraded from Qrevo Master) shares the Curv's 18,500 Pa suction, 4.1 in height, 6,400 mAh battery, PreciSense LiDAR and 167 F (75 C) wash. It adds AdaptiLift chassis lifting of up to 10 mm, warm air drying at 113 F (45 C), and a dock that also handles automatic tank refilling and wash tray self-cleaning with a stated 99.99 percent bacteria removal. It lists at $1,599.99.

That price places it above both the Saros 10R and the Saros Z70, which is the clearest argument for ignoring family names and buying on the specification that matters in your house.

Where the QV line fits

Below both families sits the QV range, which keeps the multifunctional dock and drops the sensing and suction. The Roborock QV 35A Robot Vacuum with Multifunctional Dock (Upgraded from Qrevo S) publishes 8,000 Pa, a 5,200 mAh battery, an all-rubber anti-tangle main brush with a zero-tangle arc side brush, dual mops at 200 RPM, and self-washing on a detachable cleaning tray. It stands 3.80 in tall and costs $649.99. Drying is cold air rather than warm, which is the compromise at this level.

Frequently asked questions

Is the Roborock Saros 10 worth the extra over a Qrevo?

It depends entirely on furniture clearance and carpet depth. The Saros platform is roughly an inch shorter and lifts its mops higher where the figures are published, so a home with low sofas and plush rugs gets real value from it. A home with high furniture and hard floors will not notice the difference, and a Qrevo Curv covers the same ground for less.

What makes the Roborock Qrevo Curv different from the Qrevo Edge?

They share suction at 18,500 Pa, a 4.1 in height, a 6,400 mAh battery, PreciSense LiDAR and a 167 F (75 C) wash cycle. The Edge adds AdaptiLift chassis lifting up to 10 mm, warm air drying at 113 F (45 C), automatic tank refilling and wash tray self-cleaning. Whether those additions justify the gap between $849.99 and $1,599.99 depends on how much carpet is involved.

Which Roborock vacuum suits low furniture best?

Any of the Saros models, because all three are published at 3.14 in. The Saros 10 rises to 3.68 in when its lidar mast extends and drops back down to pass under obstacles, while the Saros 10R and Saros Z70 have no mast at all. Measure the lowest clearance in the house and compare against those figures before choosing.

Do Roborock docks need plumbing?

Only the refill and drainage variants. Standard multifunctional docks hold their own clean and dirty water tanks and are filled and emptied by hand. Plumbed versions connect to a supply and a drain, which removes both chores but limits where the dock can live. Check the supply pressure and drain distance requirements for the specific model before ordering.

Choosing between the two lines

The short version: measure the lowest furniture in the house, then check the deepest carpet. Those two numbers decide the family more reliably than the product names do. If both are unremarkable, buy on dock features and price, and the Qrevo Curv becomes the sensible default.

For plumbed operation, the Roborock Saros 10 Robot Vacuum with Refill & Drainage System pairs the 22,000 Pa Saros platform with mains supply and drain at $1,399.99, and adds 8 N of mop pressure, mopping with water heated to 158 F (70 C) and 2.5-hour fast charging.
