Source verdict

The reviewer highly recommends the Roborock Saros 10R as a top-of-the-line robot vacuum for its comprehensive features, excellent cleaning, and reliable navigation. However, the Saros Z70 is not recommended for most users due to the inconsistency of its robotic arm, which often creates more annoyance than utility, making the extra cost unwarranted unless purchased at a significant discount.

About this source

This review provides a six-month long-term analysis of the Roborock Saros 10R and Saros Z70 robot vacuums. It evaluates the performance of the Z70's unique robotic arm, the overall cleaning efficacy of both models, their navigation capabilities, battery life, smart home integration, and general maintenance aspects.

Review notes

The Roborock Saros Z70 is a sophisticated robot vacuum and mop, but its flashy robotic arm fails to justify its premium price for most users. While the OmniGrip arm can miraculously pick up objects sometimes, its inconsistent reliability, often failing to move items back or getting stuck, diminishes its practical value. The Z70 excels in cleaning performance and navigation, effectively vacuuming and mopping various floor types with its dual spinning mop pads and precise obstacle avoidance. If you prioritize cutting-edge technology and are willing to pay a significant premium for an inconsistent novelty feature, consider it, especially if on sale. Otherwise, look for a model where core cleaning features are the main focus.

What the reviewer liked

  • OmniGrip robotic arm can surprisingly pick up and move objects (when it works)
  • Excellent cleaning performance on both carpet and hard floors
  • Superior spinning, rotating mopping brushes
  • Dual spinning mop pads detach to keep carpets dry (now fixed with updates)
  • Excellent navigation and obstacle avoidance (StarSight Autonomous System 2.0)
  • Slimmer design due to solid-state lidar
  • Robust app for room selection and fine-tuning
  • Good battery life (two cleaning runs for 1,000 sq ft per floor)
  • Matter integration for smart home automation
  • Remote viewing and pet snapshot feature

What the reviewer criticised

  • Robotic arm is inconsistent and can fail spectacularly (e.g., getting stuck, moving shoes but not returning them)
  • Smaller onboard dust bin compared to the 10R
  • Still leaves corners, crevices, stairs uncleaned, requiring manual effort
  • High price, especially for the inconsistent robotic arm feature
  • Battery is not user-replaceable

What is the battery life of the Roborock Saros 10R and Z70?

Despite the Z70's arm potentially draining more power, both models provided good battery life. In a 1,100 square foot apartment, they could complete vacuum and mop AI twice with battery remaining. For a larger 2,500 square foot home (1,000 sq ft per floor), each robot successfully completed two cleaning runs on one charge.

Do the Roborock Saros vacuums integrate well with smart home systems?

The robots integrate well with smart home platforms and Apple Home via Matter, allowing control over cleaning rooms, power modes, and returning to the dock, as well as providing battery status. This makes them easy to include in home automations. However, the built-in voice assistant, Rocky, had too many missed triggers and was turned off by the reviewer.

What are the main downsides of the Roborock Saros Z70 and 10R?

The reviewer highlighted two main downsides: the robots don't clean every area like corners, crevices, baseboards, and stairs, necessitating a secondary vacuum. The second downside is the high price, especially for the top-of-the-line Z70. Additionally, components like the battery are not user-replaceable, and the Z70's inconsistent robotic arm is a significant drawback.

Is the Roborock Saros Z70 worth the extra cost over the 10R?

The reviewer does not recommend the Z70 for most people, despite its premium features and higher price (typically $1,000 more than the 10R). The robotic arm is prone to getting into "weird situations" and can be more annoying than novel. If the arm feature is disabled due to inconsistency, the 10R offers better value for similar core cleaning capabilities.
