Roborock Saros Z70 Robot Vacuum and Mop with OmniGrip Arm
Our Score 98/100Integrity Score 58/100roborock
Overview
The Saros Z70 is Roborock's flagship robot vacuum and mop, and it has a folding five-axis arm that can pick up items up to 300 g, such as socks, slide sandals, crumpled tissues and small towels. Its dock empties the robot into a disposable bag, washes the two spinning mop pads with 80°C (176°F) water, dries them with 55°C (131°F) air, cleans itself with hot water and refills the robot automatically. Independent testing by Vacuum Wars, TechRadar and RTINGS found excellent hard floor cleaning, mopping and obstacle avoidance from a body only 3.14 in tall. The main gap is the arm itself: Vacuum Wars found it worked about half the time, and TechRadar could not get a fully successful automatic tidy run.
What works
- Independent testing by Vacuum Wars gave it the second best dried-on stain score it has recorded (139 against an average of 93), and it left only 0.7 g of water behind.
- Independent testing by Vacuum Wars scored its obstacle avoidance 22 out of 24 against an average of 16.6, and RTINGS found it great at avoiding pet waste.
- RTINGS rated its hard floor debris pickup outstanding, and in TechRadar's oats and loose tea test it left only one oat flake and a few tea particles on carpet after a Max pass.
- Roborock's US page and manual describe a dock that washes the mops with 80°C water, dries them with 55°C air, cleans its own tray with hot water and can drop the mops off before vacuum-only runs.
- RTINGS measured an 8.5 cm (3.3 in) clearance for getting under furniture and 3.8 cm (1.5 in) of threshold climbing, close to Roborock's 4 cm claim.
What does not
- Independent testing by Vacuum Wars found the arm worked only about half the time, and it only recognizes a short list of items for automatic pickup; TechRadar saw it misidentify sandals and socks in dim light.
- Despite the 22,000 Pa rating, Vacuum Wars measured 0.3 kPa at the intake against a 0.8 kPa average, and its carpet deep clean and flattened pet hair results (83% against a 92% average) were below average.
- RTINGS found it retracts its side brush on carpet and leaves debris along edges and corners there, and that it cannot detect USB cords or rug tassels.
- The onboard bin holds just 180 ml, the smallest Vacuum Wars has seen, and hair still tangled on the main brush in both Vacuum Wars and RTINGS testing.
- Several features are promised for later software updates rather than included now, according to Roborock's US page: custom AI object recognition, more pickable items, more safety-focused recognition and Matter support.
Who is it for
Early adopters with mostly hard floors who want top-tier mopping, a dock that handles washing, drying and refilling, and a low body that reaches under furniture. It also suits people who like the idea of steering the arm from the app to move small items, which TechRadar found works well and could help someone with limited mobility.
Who is it not for
Skip it if you are buying it for the arm to tidy up on its own, because three independent reviewers found that function limited and unreliable. Carpet-heavy homes and long-haired pets are better served by cheaper models; Vacuum Wars points to the Saros 10R or Qrevo Edge and TechRadar to the Saros 10 for similar cleaning without the arm.
Integrity
The US manual (robot RRE0R50, dock EWFD28LRR) requires a grounded 120 V outlet, lists up to 12 A draw during hot-water mop washing, limits the gripper to 0.3 kg and says to keep children and pets away while the arm moves; Roborock lists an emergency stop button, child lock, anti-pinch sensor and grip-force limit, with arm features off by default. Roborock says camera functions are off by default and claims TUV certification to ETSI EN 303 645, and it publishes a vulnerability disclosure policy and a minimum of 2 years of security updates, which is short for a product whose features are still arriving by update. We found no Roborock recall in CPSC's recall database and no UL or ETL listing for this robot or its dock. The dock uses disposable dust bags, the manual rates the mop cloths for replacement every 1 to 3 months and the main brush and filter every 6 to 12 months, and the battery can be removed with a screwdriver for recycling. Roborock's US warranty is 1 year.
