The two have a completely different mopping system but are similar in other ways.
Both models feature a dual brushroll system, strong suction, excellent climbing ability, and an advanced station.
Self-washing station
The station features:
- Auto-empty. Sucks the dustbin's content into the disposable bag.
- Auto-fill water & detergent (Dreame).
- Auto-wash & dry the mopping pads and washboard with hot water.
- Drying the mopping pads/roller.
The Dreame's station additionally dries the washboard, while the Roborock fills the tank with warm water.
Roborock best value robot
The CurvX series has a unique self-cleaning station.
Key features:
- Fills the tank with hot water
- Shorter body
- Different station
Compared to the Dreame, the CurvX lacks innovations; however, it has a lower price and warm water mopping.
Unlike Dreame, the Roborock fills the water tank with warm water
Performance:
- A retractable LDS hides under furniture.
- Upgraded climbing ability (up to 4cm).
- The new zero-tangling system is perfect for pet owners.
- Sees & recognizes 108+ types of objects.
- 3x liftable design: adaptive chassis, roller, or mops lifting.
- 30% faster charging (compared to the Roborock S7).
Has a differently-shaped station
RetractSense
The Upward Range Finder accurately measures overhead clearance, ensuring the LiDAR retracts or rises at the right moment for smooth, uninterrupted navigation.
Unlike Dreame, the CurvX hides the LDS tower under furniture.
Even tho the CurvX lacks extras, it is an ideal buy for all kinds of surface
The Roborock CurvX is made for both carpets and hard floors, only lacks the extras, the latest Dreame has.
What the Roborock lacks:
- Doesn't leave the mops at the station when they are not needed.
- Advanced climbing ability.
- Cleaning solution.
- Self-cleaning & drying washboard.
However, the Roborock is shorter, thanks to the LDS retraction, and features warm water mopping.
Dreame L50 Ultra
Key features:
- Advanced navigation & obstacle avoidance
- Better climbing ability
- Advanced self-cleaning station
The Dreame L50 Ultra uses the same obstacle avoidance technology, only knows about not as many objects.
The L50 Ultra shares the same cleaning technology, mopping features, and a self-emptying system.
Mopping features:
- Two mopping pads.
- The side brush and pad extend along the obstacles.
- Wash and dry the pads after the job.
- Auto mop removal in a vacuuming-only mode.
- Add the solution to the water container.
- Lift the pads on carpet.
- RoboSwing & Mop extend
The Dreame L50 Ultra features the premium X series ProLeap system that ensures better climbing ability.
ProLeap system helps crossing higher obstacles
The station has the premium options such as hot water washing and drying the pads, water tank refill, cleaning solution, and self-emptying.
Upgraded station cleans & dries the washboard after self-cleaning
The upgraded AceClean DryBoard uses hot water for washing the pads and for self-cleaning. After that, it dries the washboard.
Compared to the Roborock, the Dreame lacks:
- Warm water mopping
- Retractable LDS
The Dreame's self-cleaning system is more hygienic, the robot has higher climbing ability, and leaves the mops at the station when they are not needed.
Which one is the best?
The Dreame L50 Ultra does look like a better value. Customer support seems decent; the robot doesn't go under some furniture, but other than that, it is a good buy.
The Roborock Qrevo CurvX has stable navigation, better customer support in the US, and is known for its smooth movement.
