The two have a completely different mopping system but are similar in other ways.

Dreame's station features:
- Auto-empty. Sucks the dustbin's content into the disposable bag.
- Auto-fill water & detergent.
- Auto-wash & dry the mopping pads and washboard with hot water.

- ProLeap system
- AceClean DryBoard
- Retractable LDS
- Shorter than the L50 Ultra
- Auto mop removal
- RoboSwing & Mop extend
The Dreame X50 Ultra is equipped with the Industry-First ProLeap system, which is a step that helps the robot to climb up to 1.65in.
Smart Dirt Detection 2.0 checks the water to find stains and gives them a deep clean
This tech can tell apart solids, liquids, or a mix, making sure every spot is gone for a perfect clean.
Depending on cleaning tasks, the robot intelligently lifts the roller, mopping pads, and a side brush.
The robot retracts an LDS tower under furniture, making the robot shorter than the Aqua10 Ultra.
The first two roller systems (bristled & rubber) maintain hair tangles and do the job on carpet and hard floor surfaces
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 RoboSwing & Mop extend (the X series) swings the robot when it extends the mop, getting deeper for better mopping results.
The X50 Ultra features the common mopping system with two pads that rotate imitating manual mopping.
The AceClean DryBoard cleans and dries the dashboard so it doesn't stink after mopping
Dreame L50 Ultra
Upgrades over the L40s Ultra:
- Stronger suction
- Better climbing ability
- Better navigation (obstacle avoidance)
- Dries the washboard after cleaning it

The upgraded AceClean DryBoard uses hot water for washing the pads and for self-cleaning. After that, it dries the washboard.
Compared to the X50 Ultra, the L50 Ultra lacks:
- OK Dreame voice control
- Retractable LDS
- Advanced obstacle avoidance
- Suction
