Does the Roborock Saros Z70's robotic arm actually work for picking up trash and shoes?

The reviewer found the robotic arm to be inconsistent. While it could identify some items like slippers for sorting, it repeatedly failed to deposit them in the designated shoe storage zone, showing "sorting failed" messages. The arm also encountered an "Error 66" when attempting to open its hatch for trash disposal, requiring manual intervention.

How well does the Roborock Saros Z70 perform as a mop?

The Roborock Saros Z70 is an effective mop, performing well on kitchen floors. It maintains wet mop pads using an internal water tank and can automatically lift them when transitioning to carpeted areas. It also features a dirt detection sensor, allowing the base station to automatically command the robot to re-mop areas identified as unusually dirty.

What are the main downsides of the Roborock Saros Z70's obstacle avoidance?

The obstacle avoidance system proved to be inconsistent, particularly on brown speckled carpet, where the robot failed to identify and subsequently ran over crumpled paper. While it generally avoids larger shoes, its ability to detect and interact with smaller items like paper on certain surfaces needs improvement, suggesting potential limitations in its navigation software.

Can the Roborock Saros Z70 vacuum and mop simultaneously, and how does it handle different floor types?

The robot can perform vacuuming and mopping tasks, and it can even auto-detach its mop pads at the base station for vacuum-only runs. It effectively navigates with Lidar for straight-line cleaning and automatically lifts its mop pads upon sensing carpet, ensuring it doesn't wet carpets while mopping hard floors.

What types of items can the robotic arm pick up, and are there any limitations?

The robotic arm is designed to pick up small items like slippers and flip-flops, which are pre-programmed into its system. However, it cannot pick up larger objects such as big tennis shoes. The reviewer also noted issues with it successfully identifying and picking up crumpled paper on certain carpet types.

Source verdict

The reviewer found the Roborock Saros Z70's robotic arm sorting feature, especially for shoes, to be unreliable, frequently failing to reach the designated storage zone. The robot also struggled with obstacle avoidance for items like paper on brown speckled carpet, leading to disappointment despite its ability to identify items better on linoleum. The reviewer suggests the robot needs over-the-air updates to improve obstacle identification.

About this source

This review provides a detailed demonstration and test of the Roborock Saros Z70 robot vacuum and mop, focusing on its robotic arm functionality, mopping capabilities, and obstacle avoidance. The reviewer observes the robot handling various tasks like washing mop pads, navigating around obstacles, picking up items, and attempting to sort them.

Review notes

The Roborock Saros Z70 disappoints as its signature robotic arm feature does not consistently deliver on its promises. The device struggled with "error 66" during trash disposal and failed multiple attempts to sort slippers into the designated shoe storage zone. While its mopping functionality is efficient, offering automatic pad lifting and a dirt detection sensor for targeted re-cleaning, the obstacle avoidance on certain carpets proved unreliable, causing it to run over crumpled paper. If you primarily seek a high-performing vacuum and mop with intelligent features, this product is worth considering. However, if the robotic arm for object sorting is your main draw, you should look elsewhere due to its current inconsistencies.

What the reviewer liked

Effective mopping of kitchen floors
Internal water tank keeps mop pads consistently wet
Automatically lifts mop pads when carpet is detected
Extends side mop to clean close to walls
Dirt detection sensor enables automatic re-mopping of dirtier areas
Can auto-detach mop pads at the base station for vacuum-only cleaning
Uses Lidar navigation for efficient, straight-line vacuuming
Identifies large shoes for avoidance

What the reviewer criticised

Robotic arm experienced "Error 66" when attempting to open the electric hatch for trash disposal, requiring manual intervention
Struggled to successfully sort slippers into the designated shoe storage zone, repeatedly showing "sorting failed"
Inconsistent obstacle avoidance, especially on brown speckled carpet, where it failed to identify and ran over crumpled paper
The robotic arm can only pick up small items like slippers, not larger objects or tennis shoes
The shoe storage zone functionality did not work reliably, with the robot failing to reach the zone despite a clear path

Structured claims

The Roborock Saros Z70 features comprehensive automated mop pad management, including washing with hot water, internal tank refilling, automatic lifting for carpet, and detaching for vacuum-only runs, as well as extending a side mop for edge cleaning.

reviewer_claimstrong

The Roborock Saros Z70's robotic arm can identify specific items like small shoes/slippers and crumpled paper, indicating their suitability for sorting or storage zones within the app.

reviewer_claimmoderate

The Roborock Saros Z70's robotic arm is designed to pick up and sort items, such as disposing of paper into a trash can or moving slippers to a shoe storage zone, with customizable settings in the app.

specification_claimlimited

The Roborock Saros Z70 features an automatic dirt detection sensor that triggers a re-mopping event for areas identified as unusually dirty after the initial cleaning.

reviewer_claimmoderate

The Roborock Saros Z70's obstacle avoidance is generally 'just okay,' successfully avoiding large items like tennis shoes, but sometimes failing to avoid smaller objects like balls and crumpled paper, resulting in them being run over.

reviewer_claimmoderate

The robot's ability to identify and avoid obstacles, particularly paper, is negatively impacted by brown speckled carpet, where it struggles compared to its performance on linoleum.
