The biggest differences
The Roborock's innovative mechanical arm is the only one on the market. It brings the whole obstacle avoidance thing to a new level.
The Dreame has a ProLeap system that has the highest obstacle crossing ability in the industry.
Roborock Saros Z70, the King of navigation & object optimization
Key features:
- OmniGrip Mechanical Arm (handles objects up to 300g)
- Dual camera for object gripping accuracy
- Gripping manual control
- Startsigh 2.0
- AI-Powered Customization (flag an object to move)
- The new FreeFlow brush
- DirtTech technology
- Intelligent lift (adapts to messy areas, lifting the brush, side sweeper, or mopping pad)
One of the latest Saros series models features a distinct auto-empty station and ample power.
With a dual anti-tangle system and the newest brushrolls, the Saros Z70 handles hair tangling like a pro
Innovations: the OmniArm.
During its first cleaning session, the Roborock Saros Z70 marks all objects it detects to lift and clean those missed areas when circling back after the clean for the second time. The robot also relocates the objects (up to 300g) when they're blocking them from going to an uncleaned area.
The Arm is equipped with LED lights, a camera, and other sensors. With the second camera located on the robot's front, the robot sees the environment from a higher spot for better accuracy when needed to move the objects. That bunch of sensors helps the arm to determine its position, surroundings, and the weight of each object it grips.
You can control the whole gripping or relocating process in the Roborock app.
Gentle-grip design and a built-in weight sensor prevent excessive squeezing
The arm moves obstacles, lifts objects, and even organizes small household items like socks and tissues. With AI customization, users can tag up to 50 new objects, alongside 108 pre-programmed ones. The OmniArm can be controlled manually in the app.
Innovative navigation and obstacle avoidance technology
Starsight 2.0 is a next-gen 3D sensing that works with VertiBeam to recognise and avoid objects the robot senses. The Roborock navigation is one of the best on the market, and so far, no one can beat it. Roborock works on its obstacle avoidance, making navigation as smooth as possible.
The robot's body is only 3,14 in tall
Cleaning mechanics:
Roborock mopping system:
- Features two mopping pads
- Extend the pad and a side brush along the walls
- Higher mop lift
- Removes the pads on a station in a vacuum-only mode
In different situations, the robot smartly adapts to a cleaning strategy, either lifting a roller to clean spilled liquids or raising the pads on carpets.
The Roborock Saros Z70 smoothly transitions when it needs to switch between the vacuum-only to mop-only modes, lifting the roller to mop liquid spills. Unlike the DEEBOT, the Saros Z70 lifts and retracts a side brush to prevent collisions.
AdaptiLift Chassis helps it to cross up to 4 cm obstacles. The chassis automatically adapts to obstacles, lifting the front part to cross them.
Hot water mopping changes mopping completely, making the process more efficient and smooth.
SmartPlan 2.0 is a cleaning strategy that automatically adjusts cleaning settings to the dirtier areas based on a previous cleaning. The robot also suggests no-go zones where it can't go.
Pet-friendly robot
When operating, the robot detects a pet and stops; during cleanups takes pictures of your pet that you can download; allows video calling and talking to your pet in two-way voice chat.
The Roborock Saros Z70 is the most innovative robot vacuum so far
ECOVACS DEEBOT X9 PRO Omni, the best mopping robot
Key features:
- ProLeap crossing system
- Retracts the LDS
- Washes and dries the washboard
Dreame X50 Ultra
Retractable legs help to cross a higher obstacle
The Dreame's mopping system is the same; it features two mopping pads, but unlike the Roborock, the X50 Ultra mops the floors with room-temperature water.
Dreame mopping system:
- Features two mopping pads
- Extend the pad and a side brush along the walls
- Removes the pads on a station in a vacuum-only mode
Depending on the cleaning situation, a triple lift system lifts the mop on carpets to prevent wetting, raises the side brush for large debris, and lifts the main brush to avoid contamination from spills.
The retractable legs help the robot cross higher obstacles. If there is a two-step threshold, the Dreame can overstep a 2.36 in obstacle.
To Sum Up
The Roborock Saros Z10 is the most advanced robot vacuum on the market to date. Its navigation and obstacle avoidance are the most accurate. Lots of sensors and smart features automate the robot to do what it is supposed to do without much maintenance.
The Dreame X50 Ultra saves you a dollar. You'll miss some extras like the mechanical arm or hot water mopping; however, with the Dreame's retractable legs, the robot can overcome more obstacles without getting stuck.
Both are top-tier robots in the lineup and are some of the best in 2025.
