In 2026, we’ve moved past the era of robots that simply bump into walls. We are now in the era of robots that interact with our clutter. The Roborock Saros Z70 is the world’s first mass-produced vacuum with a five-axis mechanical arm, designed to end the “pre-cleaning” chore forever.

But at its premium price point, is this a revolutionary utensil for your home, or just a very expensive toy? After 90 days of testing, here is our deep dive.

1. The Star of the Show: OmniGrip™ Mechanical Arm

The most common question we get at Best Gadget Compare is: “Does the arm actually work?”

The Reality: The Saros Z70 doesn’t just “detect” a stray sock or a slipper; it uses its OmniGrip™ arm to pick it up, move it to a spot it has already cleaned, and then vacuums the area where the clutter was sitting.

• What it can lift: Socks, flip-flops, crumpled tissues, and small towels (up to 300g).
• The “Companion” Aspect: You can even use the app to manually control the arm like a remote-controlled claw machine—handy for grabbing a TV remote that fell under the couch.
• The Catch: It’s not perfect. It struggles with very flat items like charging cables, which it still sometimes tangles in its main rollers.

2. Power & Performance: 22,000 Pa HyperForce®

The Z70 isn’t just about the arm. It currently holds the record for some of the highest suction in the industry at 22,000 Pa.

• Anti-Tangle Mastery: If you have long hair or pets, the Dual Anti-Tangle System is a lifesaver. It features internal blades that micro-cut hair before it can wrap around the rollers. In our 3-month test, we never had to manually clear the brush once.
• Ultra-Slim Design: At only 7.98 cm tall, it fits under almost any cabinet or modern sofa. It achieves this by removing the “LiDAR tower” from the top and moving the sensors to the front and the arm itself.
• AdaptiLift™ Chassis: This is a 2026 standout. The robot can physically “stand up” on its wheels to climb over thresholds up to 4 cm high, making it the best in class for homes with high door dividers.

3. Saros Z70 vs. Saros Rover: Which one climbs stairs?

There has been some confusion in the community. While the Saros Z70 uses its arm to move clutter, it is NOT a stair climber.

If you have a multi-floor home and want a vacuum that can actually walk up your staircase, you are looking for the Roborock Saros Rover (released at CES 2026). The Rover uses a “wheel-leg” architecture to step up 20cm rises. For the Z70, you still need to carry it between floors—though its multi-floor mapping software is the best we’ve seen.

Final Verdict: Is it worth it?

The Roborock Saros Z70 is for the person who wants the absolute cutting edge of 2026 robotics. If your home is constantly “messy” with small items that usually get a robot stuck, the Z70 is the first vacuum that actually solves the problem instead of just complaining about it.

However, if your floors are usually clear and you just want the strongest suction possible for deep carpets, the Dreame X60 Max Ultra offers more raw power for a lower price.
