The two seem very similar, with the same mopping system, cleaning mechanics, and an advanced self-cleaning station.
The difference:
Multifunctional Dock vs. Multifunctional Dock 3.0 Thermo+. The Thermo+ is an advanced station with extras.
Navigation technology. The CurvX hides the LDS under furniture and has better obstacle avoidance technology.
RetractSense 9Qrevo CurvX
The Upward Range Finder accurately measures overhead clearance, ensuring the LiDAR retracts or rises at the right moment for smooth, uninterrupted navigation
Mopping. The CurvX features better mopping features.
Roborock mopping technology:
- Features dual mops
- Lifts the mops on the carpets
- Extend the mop (and side brush) along the walls and around furniture
- Washes and dries the mops on the station
- Mops the floors with hot water
Best value
The S5V is powerful, but lacks some premium lineup options. Features:
- The strongest suction
- Extend the mop along the walls
- DuoDivide rollers
- Features a 3-stage dynamic cleaning process
Compared to the latest models, the S5V's obstacle avoidance is not as advanced, and the robot lacks a Voice assistant and remote viewing; however, it has everything you wish for the price.

Roborock Qrevo CurvX
Upgrades over the Qrevo S5V:
- Hot mopping
- Intelligent re-wash and re-mop (dirt detection)
- Self-cleaning with hot water
- Washing the pads with hot water
- Better climbing ability thanks to the AdaptiLift Chassis
- Stronger suction
- Shorter body thanks to the Retractable LDS
- Upgraded anti-tangle system
- Extends a side brush along the walls
Unlike the S5V, the CurvX has a station with extras.
An advanced station might be the most significant difference between the two.
The station uses hot water for washing the pads, self-cleaning, and adds it to the water tank for warm water mopping.
As to mopping, the CurvX intelligently detects and re-washes stains, mops with hot water, and since the pads get washed with hot water, they don't stink and are ready for the next turn.
Intelligent advanced mopping
With strong suction, the CurvX is more suitable for deep carpet cleaning.
With RetractSense, the robot hides the LDS under furniture and elevates in open space.
A cheaper alternative to the top-tier Saros 10R
Which one to get?
Depending on design preference, it depends on what you want.
The Qrevo CurvX is a great buy if you need an advanced mopping experience and stronger suction for vacuuming carpets. At a higher price, you get a robot that performs better as a mop and as a vacuum, and is an intelligent premium model with extras.
The Qrevo S5V is a cheaper model that might not be as efficient at mopping as its premium sibling, however, it is a great buy for the price considering its features.
