Overview

The Roborock Saros Z70 is a robot vacuum and mop with OmniGrip, a retractable five-axis robotic arm that folds into the robot and can pick up and move light items of up to 300 g. It has 22,000Pa HyperForce suction, the StarSight Autonomous System 2.0, VertiBeam lateral obstacle avoidance and two cameras, one on the arm and one at the front, and it recognises 108 types of obstacle. You can teach it up to 50 new objects in the app.

The FlexiArm Riser Mop reaches edges and corners and lifts up to 22 mm when the chassis rises, and the robot can leave its mops in the dock for vacuum-only and carpet jobs. The dock empties the robot for up to 60 days, washes the mops with water up to 80°C, dries them and the dock base with 55°C warm air, refills with warm water and doses detergent from a 590 ml tank. The 7.98 cm robot climbs double thresholds up to 4 cm, has a 6,400mAh battery with 2.5-hour charging, and works with Alexa, Siri and Google Home, with Matter coming in an update.

Pros & Cons

Pros

+ Robotic arm moves small items out of the way
+ StarSight 2.0 navigation with two cameras
+ Automatic detergent from a 590 ml tank
+ Slim 7.98 cm body

Cons

− Lower suction than the Saros 20 and Saros 20 Neo

Setup & Installation

Place the dock on a hard, flat floor against a wall, leaving at least 0.75 m of height, 0.4 m of width and 1.2 m of space in front. Fill the clean water tank with cold water only. If you use floor cleaning solution (sold separately), add it to the 590 ml detergent tank. Download the Roborock app, tap “Add Device” or “+” and follow the in-app guide. The robot connects on 2.4GHz Wi-Fi only, so choose your 2.4GHz network.

To switch the OmniGrip arm on or off, fold it away, then hold Power/Clean and the Emergency Stop button together; you then use the arm through the Roborock app. The mid-to-high-pile carpet mode is switched on manually in the app, and you can teach the robot up to 50 new objects.

Common Problems & Fixes

Who Should Buy It

Anyone whose floors often have small items left on them and who wants a robot that can move them out of the way.

Verdict

The Saros Z70 is the robot to pick if clutter is your main problem: its arm can move small items out of the way. For pure cleaning power, the Saros 20 has more suction and a hotter mop wash.
