Roborock Saros Z70: review
The Roborock Saros Z70 is the first Roborock robot fitted with a robotic arm — OmniGrip™ — designed to grab small objects off the floor before vacuuming. At 799 €, it's also, on paper, the cheapest of the recent Saros models.
Verdict in brief
The Saros Z70 is the most distinctive bet in the 2026 Roborock range: a robotic arm rather than a race for raw suction. Its price, lower than the Saros 20 and 20 Sonic, makes it an interesting entry point into the Saros flagship tier — provided you accept that the manufacturer doesn't specify the mopping technology.
✓ Pros
- OmniGrip™ robotic arm: picks up small objects before vacuuming
- Lower price than the Saros 20 and 20 Sonic (799 €)
- VertiBeam obstacle avoidance + RGB camera
- 6 400 mAh battery
✕ Cons
- 22 000 Pa: noticeably less than the Saros 20’s 36 000 Pa
- Mopping technology not specified by Roborock
- Detailed dock features not disclosed
Who is it for?
Households that regularly leave small objects on the floor (socks, light toys, cables) and who prefer this feature to the catalogue's strongest suction.
Skip it if…
Raw suction is your absolute priority: the Saros 20 (36 000 Pa) or the Sonic (36 000 Pa + VibraRise 5.0) do better on this specific point, for a higher price.

Our scores by criterion
The OmniGrip arm is a navigation/manipulation feature in its own right, not measurable on the usual navigation scale alone — we flag it in the text rather than artificially inflate a score.

The Z70 trades raw suction (22 000 Pa versus 36 000 Pa) for the OmniGrip arm and a price 490 € lower than the Saros 20. The choice comes down to one question: is object pickup worth more, for your home, than maximum suction?

Frequently asked questions
Does the Saros Z70’s OmniGrip arm really pick up objects off the floor?
That’s the feature Roborock documents: a robotic arm designed to grab small objects (socks, light cables) sitting on the floor before the robot vacuums that spot. We haven’t physically tested this feature — see our method.
Does the Saros Z70 suction as hard as the Saros 20?
No: 22 000 Pa versus 36 000 Pa for the Saros 20. The Z70 bets on the OmniGrip arm and a more accessible price (799 € versus 1 289 €), not on the series’ highest suction.
What is the Saros Z70’s mopping technology?
Roborock doesn’t name it specifically on the Z70’s official listing, unlike other Saros models such as the Saros 20 Sonic (VibraRise 5.0). That’s a lack of transparency on a point that matters for everyday mopping.
