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.
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.
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.

The OmniGrip arm features a camera and additional sensors to identify, pick up, and move objects to a chosen location or a paper bin. The reviewer notes that when it works, it's "like magic" and fulfills the novelty factor.

The robotic arm does not work consistently. The reviewer observed it failing to pick up a shoe for three minutes and sometimes failing spectacularly, like moving shoes off a rack or failing to return moved items.

Users can manually train the robot for object recognition to improve its accuracy. A convenient stop button is included to interrupt unwanted actions by the robotic arm.

Both the Saros 10R and Z70 offer excellent cleaning performance. They effectively cleaned carpets in the reviewer's old apartment and hard flooring in their new home, efficiently picking up dust and scrubbing floors.

The reviewer believes the spinning, rotating mopping brushes on both Saros robots are superior to the vibrating mopping pads found on their older Roborock vacuum models.

On hard floors, visible marks can be seen where the robot has vacuumed or mopped. However, the reviewer doesn't mind this, and an app setting allows the robot to mop along floor patterns to reduce these marks.

Both robots feature dual spinning mop pads that detach to keep carpet dry. Initially, the reviewer experienced issues where only one pad would detach during vacuum-only runs, but recent software updates have resolved this problem.

The Z70 has a smaller onboard dust bin to accommodate its robotic arm. The 10R is expected to perform better in cleaning due to its superior roller brush design.

The navigation for both robots has been excellent in two different home locations, even with clutter. They haven't damaged plants and consistently find their way back to the dock without issues.

Occasionally, the robots will run over small items like socks or parts of shirts in a closet, getting stuck and requiring manual intervention to free them.

The robots have been impressive at avoiding cords, with the reviewer stating they have avoided running over "pretty much any cord that they've come in contact with."

The robots demonstrated good battery life, completing two vacuum and mop AI runs in a 1,100 square foot apartment with battery left. In a larger 2,500 square foot home (1,000 sq ft per floor), they completed two cleaning runs on a single charge.

The built-in voice assistant, named Rocky, had "so many missed triggers" that the reviewer ended up turning it off on both robots due to unreliability.

Despite having a lot of technology, key components like the battery are not user-replaceable. The reviewer expresses a desire for Roborock to make the battery user-replaceable.

While the Z70's OmniGrip arm can identify, pick up, and move objects, the reviewer found its performance inconsistent. It works "like magic" sometimes but frequently fails to complete tasks or moves items without returning them, making it more of an annoyance than a consistent feature. Manual training and a stop button are available to mitigate some issues.
The reviewer found the cleaning performance of both the 10R and Z70 to be excellent. They effectively cleaned carpets in an old apartment and hard floors in a new home, picking up dust and scrubbing surfaces comparable to manual cleaning. The spinning mop brushes are considered superior to older vibrating pads.
Both robots demonstrated excellent navigation in two different home environments, including one cluttered during a move. They avoided plants and cords effectively, consistently finding their way back to the dock. However, they sometimes run over small items like socks, requiring manual intervention to get unstuck.
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.
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.
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.
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.
75/100 source quality
In this 6-month review of the Roborock Saros 10R and Z70, the reviewer details their long-term experience with these flagship robot vacuums. While the Z70's robotic arm can be impressive, its unreliable performance makes it less practical than advertised. Both models deliver excellent cleaning on various floor types, largely attributed to their superior spinning mop pads and effective navigation system. Key drawbacks include the robots' inability to clean all household corners and their premium price. The reviewer ultimately favors the 10R for its consistent performance and value, advising against the Z70 for most users due to its problematic robotic arm.
