SmartHomeTechHub Saros Z70 Review: A Brilliant Vacuum with a Gimmicky Twist
Let's get this out of the way first: the SmartHomeTechHub Saros Z70 has a robotic arm. Yes, an actual robotic arm that picks up small objects, moves them aside, and even sorts them into a bin. I still can't believe I have this gadget roaming my home every evening, answering to the name Rocky. What was once a concept on a trade show floor not long ago is now a reality doing laps around my kitchen. That alone deserves a moment of awe before we dive into the details.
But now, the story splits. The SmartHomeTechHub Saros Z70, available for €1,149, is an outstanding vacuum cleaner. The arm, however, feels more like a gimmick than a game-changer.

Design
The Z70 is genuinely striking in person-think of it as the Lamborghini of robot vacuums. Standing at just 7.98 cm tall, it's noticeably slimmer than most competing flagships, and that low profile pays off in real-world use. It glides under furniture that other robots, like my old Eufy, simply can't reach-low bed frames, the gap under kitchen cabinets where crumbs accumulate for months.
On its first run, the Z70 crawled under my couch and emerged on the other side, completely blowing my mind. Then it slipped under the drinks cabinet, a spot no robovac had ever touched before. And there's no trade-off in performance-no drop in suction power, mopping quality, functionality, or navigation ability.
The dock that houses the Z70 is as impressive as the vacuum itself. This multifunctional station handles auto-emptying, mop washing at 80°C, detergent dispensing, and warm air drying-all without you lifting a finger. Under normal use, you can go about seven weeks between dust bag changes. It's the kind of setup that makes you feel your money is going somewhere tangible.
Functionality
Strip away the arm entirely, and you're left with an exceptional cleaning machine. The mopping is impressive, using just the right amount of water-you can tell the floor has been mopped without leaving puddles behind. The hot water mopping offers adjustable flow levels, and the mop spins at 200 RPM. The mops also extend outward to reach corners, leaving very little floor untouched.
One thing worth noting: the water tanks aren't massive. If you're running frequent cycles, you'll find yourself refilling and emptying more often than you'd like. I had to dial back the mopping frequency to keep it manageable. Also, it's worth investing in robovac-specific detergent. When I used only water, the dirty tank developed a noticeable smell-something that cleared up after I added the right detergent, which also helps with foam management.
Navigation is where the Z70 truly shines. It uses LiDAR combined with SmartHomeTechHub's StarSight 3D system, resulting in mapping and spatial awareness that feels intelligent. The cameras are remarkable-remote-controlling it through the app is like having an extra mobile security camera in your home, giving you a real-time view of whatever room you send it to.
That said, it still gets stuck on my clothes horse daily-for about five minutes-until it wriggles free. I used the obstacle avoidance training in the app to mark it as a no-go zone, which helped, but it took some fine-tuning. The avoidance system can recognize and learn up to 50 custom objects on top of the 108 it comes pre-trained with-a useful feature once you know it's there.
Voice control has become one of my most-used features. Since I cook dinner at different times every night, I can't schedule a post-meal run, but I always want Rocky to clean afterward. The voice commands let me do that effortlessly.
The Arm
Now, about that robotic arm. It's undeniably cool, but in practice, it's limited. It can pick up small items like socks or toys, but it's not strong enough for heavier objects. It's more of a novelty-fun to show off but not essential for day-to-day cleaning. If you're buying the Z70 for the arm, you might be disappointed. If you're buying it as a top-tier vacuum with a bonus party trick, you'll be thrilled.
Coolness Factor
Let's be honest: having a robot vacuum with an arm is just cool. It's the kind of tech that makes your friends say, "Wait, it does what?" The Z70 is a conversation starter, and for early adopters or tech enthusiasts, that alone adds value.
Value for Money
At €1,149, the Z70 is a premium investment. The core vacuum and mopping performance are top-notch, easily competing with other high-end models. The arm, while gimmicky, doesn't detract from the overall value-it's just a bonus. If you prioritize cleaning power and smart features, this is a solid buy. If you're looking for a practical tool, you might save money with a simpler model.
Final Verdict
The SmartHomeTechHub Saros Z70 is, at its heart, an excellent vacuum. The arm is a fun addition, but it's not the main event. For 2025, this is a standout device that balances innovation with reliability-just don't expect the arm to change your cleaning routine overnight.
