Roborock Qrevo, Saros and Q series explained

The three families at a glance

Think of the range as a ladder. At the bottom is the Q series, a lidar robot that vacuums and wipes but leaves the cleaning of the cloth to you. In the middle sits Qrevo, which hands most chores to a dock. At the top is Saros, where the robot itself changes: more suction, a thinner body and a chassis that lifts over bigger obstacles.

The table below uses listing details for one representative model from each family.

Q series: lidar without the big dock

The Q7 BF is the entry model in the current listings. It maps with lidar, so it cleans room by room rather than bouncing around, and it vacuums and wipes in one pass. The charging station is compact and only charges the robot. You empty the 325 ml dust box yourself and rinse the cloth by hand, which is the trade you accept for a small footprint.

That makes the Q series a fit for a one or two bedroom flat, or for a household that vacuums every day and does not need weeks between chores. The listing does not give a suction figure, so do not compare it with the Qrevo and Saros numbers directly. If you want something with a similar footprint, see our guide to robot vacuums for small flats.

Qrevo: the dock does the chores

Qrevo is the family to look at if you want the robot to look after itself. On the Qrevo 5AE listing, the dock empties dust into a bin rated for up to 7 weeks, washes the mops, dries them with hot air and refills the clean water tank. The mops are two spinning pads at 200 rpm on a FlexiArm that swings out towards edges, and they lift 10 mm to stay off short-pile carpet. Suction is stated at 12,000 Pa, and the robot can store up to 4 floor plans for multi-level homes.

The Qrevo Curv is a newer variant. Its listing mentions the multifunction dock 3.0, listed as bagless, and the AdaptiLift chassis that helps with thresholds, but it gives no suction, runtime or height figures. That is a reason to read Roborock's own spec sheet before choosing it over the 5AE. Neither listing states the robot's height, so measure your furniture gaps first with the clearance check tool.

Saros: slimmer, stronger, higher-climbing

Saros is Roborock's top family and the one to pick if your sofa or bed leaves a low gap. The Saros 10 and Saros 10R are both listed with 22,000 Pa suction and an 8 cm body. The 10R listing adds an AdaptiLift chassis that climbs thresholds and U-shaped furniture legs up to 4 cm, plus 3D detection for tight spaces under cabinets. The Saros 10 lists 220 minutes of runtime and ships with the RockDock Ultra 2.0, a dust bag and a double anti-tangle brush system.

The Saros Z70 is a different idea. Its listing highlights an OmniGrip arm and a multifunctional docking station 4.0, bagless. The arm is meant to pick up small items from the floor, which is a niche feature; our explainer on robot vacuums with an arm covers what such arms can and cannot do. For thresholds and ledges in general, see how high robot vacuums can climb.

Reading the name on a listing

Roborock names are less consistent than some rivals', so use the name as a hint and the listing as the proof. A Qrevo or Saros name tells you the family. Numbers and letters after it point to the generation or the dock version, and the descriptions in the listing tell you what is in the box. The 5AE, for instance, is described on its listing as an upgraded version of the S7 Max Ultra, which shows that older names live on inside newer ones.

Check three things before you buy. First, whether the dock is bagged or bagless, because that sets your running costs in bags and how often you handle dust. Second, the stated robot height, since a few millimetres decide whether it fits under your furniture. Third, that the listing is for a UK plug and a UK dock, not an import. One Q7 BF listing in the Amazon results is written in Spanish for a different market, so read the title closely.

Which family suits which home

Choose the Q series if space is tight, the floors are mostly hard and you are happy to rinse a cloth. Choose Qrevo if you want weeks between chores and a mop that stays clean, and your furniture is not especially low. Choose Saros if you have low sofas or beds, steps between rooms, or a large home where runtime counts.

If you are weighing Roborock against another brand, our comparisons of Roborock vs Dreame and Roborock vs Ecovacs set the docks and mops side by side. If a Roborock misbehaves after you buy it, the Roborock troubleshooting page covers lidar errors, noise and dock faults.

Frequently asked questions

Is Qrevo better than Q series? Qrevo adds a dock that empties dust, washes and dries the mops and refills water, so it needs far less attention. The Q series is smaller and simpler. Better depends on whether you want the dock to do the chores or want a compact set-up.

Is Saros better than Qrevo? Saros listings state higher suction, 22,000 Pa against 12,000 Pa on the Qrevo 5AE, and an 8 cm body. If your furniture is low or your home is large, that matters. If not, a Qrevo covers most needs.

What does the number after Saros mean? Roborock does not publish one simple rule. Treat it as a model or generation marker and compare the listing details, such as suction, height and dock, rather than the number alone.

Do Roborock robots work with Alexa and Google Home? Many Roborock listings mention app and voice control, but support varies by model. Check the listing and Roborock's compatibility list before you rely on a particular assistant.
