The premium Qrevo robots feature the most advanced self-cleaning stations and sophisticated object recognition technology.
AdaptLift Chassis enables the chassis to lift by 10mm or elevate the front, left, rear, or right sections. Thanks to it, the robot climbs up to 4 cm, which is the highest in the industry. This feature lifts the chassis and mops on mid-to-long-pile carpets.
Multi-functional base 3.0
The advanced base does the following things:
- Self-empty
- Auto-wash the mops with hot water & dry them with hot air
- Auto-fill the water tank
- Cleans the dock base with hot water
- The detachable dock base has an upgraded design, so it stays nice and clean after every wash and is easier to maintain
- DirtDetect monitors the dirt levels, adjusting the wash duration, and if it detects heavy stains, the robot returns to the dock to re-wash the mops
- Fast charging & Off-peak charging
All you have to do is fill the water container and start the robot.
In the app, you can set:
- washing mode
- drying mode
- emptying mode
Pet-friendly robot
When operating, the robot detects a pet and stops; during cleanups, it takes pictures of your pet that you can download; it allows video calling and talking to your pet in two-way voice chat (CurvX and Curv 2 Pro).
Newest navigation technology
RectractSense retracts the LDS tower under furniture, making the robot shorter than the previous generation.
The most affordable
Compared to the CurvX, the Curv S5X lacks:
- AdaptiLift Chassis
- Warm water refill
- LDS retraction
- Video call/remote viewing
- Pet snaps
When washing the mopping pads, the upgraded base station allows choosing water temperature (room temperature, warm, and hot water), wash mode (smart, light, balanced, deep), and warm air drying duration (2, 3, 4 hours).
The most affordable premium robot
Compared to the other Curv modification, this lacks some extras like warm water refilling or better climbing ability. Instead, it has the premium features at a lower price and contains more accessories (3 disposable bags, 1 extra DuoDivide roller).
Qrevo Curv S5X vs Curv.
The latest features: AdaptiLift Chassis, stronger suction.
Roborock Qrevo CurvX
The CurvX features extras, which increase the price.
Upgrades over the Curv
- Stronger suction
- Fills the tank with hot water
- RectractSense
- Shorter body
- Video call/remote viewing
- Pet snaps
- SmartPlan 2.0
With RetractSense, the robot hides the LDS under furniture and elevates in open space. With stronger suction and warm water refill, it provides a smoother cleaning experience for both vacuuming and mopping jobs.
A cheaper alternative to the Saros 10R
The CurvX lacks:
- mop removal
- detergent dispenser
Instead, the CurvX features a different navigation system that retracts the LDS tower under furniture and older obstacle avoidance technology.
The best value with some premium extras and a reduced price tag
Compared to the Saros (which is the latest and most expensive lineup), the Qrevo CurvX features extras of the best models in the market, yet comes at a lower price.
Qrevo CurvX vs. Curv 2 Pro
The Curv 2 Pro uses hotter water temperature for washing and self-cleaning, and also has stronger suction. However, it is not available on Amazon yet.
To sum up
The editor's recommendation is the Qrevo CurvX
The robot has the Saros' extras, is suited for deep carpet cleaning, and provides the best mopping experience.
If you want to save a dollar, get the Qrevo Curv S5X. Still a valid buy that might not be as good at mopping, yet has lots of power for vacuuming your floors.
