Not as advertised — Roborock's OmniGrip arm is real, functioning hardware, but independent reviewers measured roughly a 50% success rate picking up socks, tissues, and similar clutter, so 'forget the pre-cleaning hassle' doesn't hold up for most households.

BUYING THE HYPE
▸ HYPE VS REALITY
Roborock markets the Saros Z70's retractable OmniGrip robotic arm as letting owners "forget the pre-cleaning hassle" — the vacuum is advertised to detect, grip, and relocate small floor clutter like socks, sandals, and tissues on its own during a cleaning run, then circle back to clean the newly-exposed floor.
Independent reviewers tested OmniGrip's real pickup rate after the Z70 reached the US market and found it well short of 'forget pre-cleaning.' RTINGS' lab testing found the arm's performance was 'hit or miss,' succeeding on some runs and failing on others with socks, paper balls, and slippers even under favorable, staged conditions. Vacuum Wars concluded that 'even if you only had socks, clumps of paper, and slides in your house, it would still only work about half the time,' and reported specifically weak results with slide-style sandals. Reviewers broadly agree OmniGrip is real, working hardware, but describe the software's object-handling as an early-adopter novelty rather than a reason to skip tidying before a clean.
OmniGrip is real, functioning hardware — a robot vacuum with a retractable arm that genuinely can identify and lift small objects — but Roborock's 'forget pre-cleaning' promise overstates it substantially: independent testers converge on roughly a 50% success rate on a narrow list of items, meaning most households still need to tidy the floor first.
This verdict would change if new, independently verifiable evidence emerged directly supporting the claim "The Saros Z70's OmniGrip arm lets you 'forget the pre-cleaning hassle' before it vacuums." — evidence stronger than what's currently on record contradicting it.

▸ FAQ
What is the Roborock Saros Z70's OmniGrip arm supposed to do?
It's a retractable robotic arm built into the vacuum that's marketed to detect small floor clutter — socks, tissues, slippers, sandals — grip it, and move it aside so the vacuum can clean underneath, letting owners skip picking up before a cleaning run.
Does the OmniGrip arm actually work?
Independent reviewers at RTINGS and Vacuum Wars found it works roughly half the time on the narrow list of objects it's designed for, and it struggles specifically with slide-style sandals — a real but unreliable feature rather than the 'forget pre-cleaning' experience Roborock advertises.
