Our take
Roborock Saros Z70
A very good robot vacuum with an attention-grabbing arm rather than a robot you should buy for the arm. Owners like the core cleaning and navigation; the pickup arm is still more novelty than essential feature.
Owners praise Roborock's app, everyday cleaning and navigation in cluttered homes.
The robotic arm adds cost and complexity without consistently improving cleaning, and some owners see it as a gimmick.
Early adopters who want automated floor cleaning plus limited small-object pickup.
Buyers seeking proven value, immediate UK stock or general-purpose tidying.
- OmniGrip five-axis mechanical arm
- 22,000Pa suction — an advertised pressure figure, not a cleaning score.
- A 7.98cm-tall body can reach under low furniture; check the gap beneath yours.
What reviewers found
The Z70’s ordinary cleaning is better established than its headline robotic arm. Reviewers found a capable vacuum and mop, while early autonomous object handling fell well short of a general tidying assistant.
The arm is the uncertain part
TechRadar could control the arm successfully through the app but could not make it reliably tidy objects automatically during its two-week test. Supported items and successful positioning were restrictive. That review reflects the tested software at the time; promised updates should not be treated as demonstrated improvements without a fresh test.
[1]Cleaning can be good without the arm
TechRadar praised vacuuming and the extending mop’s edge coverage. RTINGS also found excellent hard-floor pickup and strong mopping. The useful distinction is that these cleaning strengths do not depend on the arm turning into a dependable household helper. Buyers should decide whether object handling itself justifies the premium.
[1][2]Carpet edges and hair maintenance
RTINGS found the side brush retracted on carpet, leaving edges and corners less thoroughly cleaned. Hair pickup was good, but longer hair could wind around the main roller. A robot that collects fur effectively may still need manual brush cleaning, and that should be part of the expected routine.
[2]Navigation, noise and daily use
Both tests supported good navigation and access beneath low furniture. TechRadar reported a rattle on its sample and noticeable dock noise, while RTINGS found ordinary running quiet. These observations concern different sounds, rather than proving a contradiction. Overall, the evidence is stronger for useful floor cleaning than for paying extra to avoid picking things up yourself.
