Key Differences Between Roborock Saros Z70 and Dreame X50 Ultra

  • Robotic Arm: The Roborock Saros Z70 features a unique 5-axis OmniGrip mechanical arm, capable of picking up small objects (up to 300 grams) like socks or pet toys and storing them in a designated compartment. This is a groundbreaking feature not found in the Dreame X50 Ultra, which lacks any robotic arm functionality.
  • Suction Power: The Saros Z70 offers a superior 22,000Pa suction power, excelling at cleaning fine debris on both hard floors and carpets. The Dreame X50 Ultra, with 20,000Pa, is slightly less powerful but still performs strongly, particularly on carpets.
  • Obstacle Avoidance: The Dreame X50 Ultra has a slight edge in obstacle avoidance, performing better in tests by avoiding common hazards like cords and furniture legs more consistently. The Saros Z70’s StarSight System 2.0, while advanced, occasionally struggles with table legs.
  • Height and Clearance: The Dreame X50 Ultra has a retractable LiDAR system, allowing it to achieve a lower profile (89.5 mm) to navigate under furniture. The Saros Z70 is slightly slimmer at 79.8 mm, making it the thinnest model tested, ideal for low-clearance areas.
  • Threshold Crossing: The Dreame X50 Ultra can cross thresholds up to 2.36 inches (42 mm), significantly higher than the Saros Z70’s 1.18 inches (30 mm), making it better for homes with varied floor heights.
  • Mopping System: The Saros Z70 uses a VibraRise 4.0 mopping system with a mini edger mop head, excelling in edge cleaning. The Dreame X50 Ultra employs a dual-spinning mop pad with an extendable mop for better edge coverage, though it may require more maintenance.
  • Price: The Saros Z70 is priced at $1,999, significantly higher than the Dreame X50 Ultra at around $1,699, reflecting its robotic arm and premium features.

Key Similarities Between Models

  • Navigation Technology: Both models use advanced LiDAR-based navigation systems with retractable sensors for precise mapping and obstacle avoidance, capable of creating detailed 3D home maps.
  • Multi-Function Docks: Both include all-in-one docking stations that self-empty dustbins, wash and dry mop pads, and refill water tanks, reducing maintenance.
  • Battery Life: Both feature a 6,400 mAh battery, offering up to 180–300 minutes of runtime, suitable for large homes.
  • Smart Features: Both support AI-powered apps with real-time cleaning reports, customizable multi-floor mapping, and compatibility with Alexa and Google Assistant for voice control.
  • Anti-Tangle Brushes: Both employ anti-tangle brush designs—Dreame’s DuoBrush with dual tapered rollers and Roborock’s DuoDivide with a split roller—effectively handling pet and human hair.
  • Noise Levels: Both operate quietly, with the Saros Z70 at 50 dB in eco mode and the X50 Ultra noted for low noise, making them suitable for daytime use.

Conclusion

The Roborock Saros Z70 stands out as the more innovative model due to its groundbreaking OmniGrip robotic arm, higher suction power (22,000Pa), and ultra-slim 79.8 mm profile, making it ideal for homes with low furniture and small clutter.

Its superior hard-floor cleaning and edge mopping performance further enhance its appeal for tech enthusiasts willing to pay a premium ($1,999). However, its higher price and occasional navigation issues with table legs are drawbacks. The Dreame X50 Ultra, priced lower at $1,699, offers better obstacle avoidance and excels at crossing higher thresholds (2.36 inches), making it more versatile for homes with varied floor heights.

Its mopping system is effective, though slightly less precise on edges compared to the Z70. For most users, the Dreame X50 Ultra provides a better balance of performance and value, especially for carpet-heavy homes or those with complex layouts. The Saros Z70 is the better choice for those prioritizing cutting-edge features and hard-floor cleaning, despite its cost and minor navigation flaws.
