Roborock Saros Z70 Review: The Robot Vacuum With a Robotic Arm That Still Cleans Like a Flagship
Powerful 22,000Pa suction, hot-water spinning mops, sharp StarSight navigation and a self-maintaining dock, wrapped around a headline OmniGrip arm that still feels like beta and a premium price.
The Roborock Saros Z70 is a flagship robot vacuum and mop built around a genuinely new idea: a five-axis OmniGrip arm that lifts slippers, socks and small clutter out of the way before it cleans. Underneath that party trick it is a seriously capable machine, pairing 22,000Pa suction with hot-water spinning mops, fast and accurate StarSight navigation, an ultra-slim body that slips under low furniture and a multifunction dock that empties the bin and washes and dries the mops on its own. Owners consistently say it cleans hard floors superbly and runs quietly, but the arm still feels like early technology, several report it jamming or failing after a few weeks, and the price is very high unless you catch one of its frequent deep discounts. For hard-floor homes that want the most advanced robot on the market and can live with first-generation quirks, it is a standout; bargain hunters and anyone who needs rock-solid reliability should think twice.
- Hard-floor and mixed-surface homes

Pros
- Powerful 22,000Pa suction that lifts pet hair, crumbs and fine dust from hard floors
- Hot-water dual spinning mops with auto wash, dry and carpet lift leave floors genuinely clean

- Very high price at full retail; much easier to justify on a discount
- Small onboard dustbin that depends on the dock to keep up

Who is the Roborock Saros Z70 for?
This is a top-of-the-line vacuum-and-mop combo for people who want the most advanced robot available and are willing to pay for it. It delivers 22,000Pa of suction with a zero-tangling main brush and extending FlexiArm side brush, full hot-water mopping with dual spinning pads that auto-wash, dry and lift for carpet, and a self-emptying multifunction dock that also refills the robot with water and detergent. It navigates with StarSight solid-state LiDAR plus obstacle and cliff detection, maps multiple rooms quickly and supports no-go zones, runs up to 180 minutes and stays quiet in use. Its signature hardware is the ultra-slim 3.14-inch body, which owners note fits under furniture that stopped their older robots, and the OmniGrip mechanical arm. It connects over 2.4GHz Wi-Fi and works with Amazon Alexa, Google Home, Apple Home, Matter and Home Assistant. In practice it suits hard-floor and mixed-surface homes, households with pets and kids that generate daily crumbs and hair, and anyone stepping up from an older iRobot, Neato or entry-level Roborock.
What buyers love
The recurring verdict is that it cleans superbly and takes real work off your hands. Owners praise strong vacuuming that picks up everything from pet hair to fine dust, and single out the hot-water spinning mops as a highlight, saying floors and even white socks come out noticeably cleaner and that the dirty-water tank proves the mops are actually lifting grime rather than smearing it. Navigation is the other standout: mapping is fast and accurate, the robot rarely bumps into things, and because the LiDAR sits inside the low-profile body it slides under cabinets and beds that blocked previous robots. The multifunction dock earns constant praise for self-emptying, washing and drying the mops and refilling water and detergent, keeping day-to-day maintenance minimal. Many describe it as noticeably quieter than older robots and traditional vacuums, and a wave of upgraders from iRobot and Neato call it a dramatic step up, with several also noting fast recharging and good battery life.
How good is the OmniGrip robotic arm?
The OmniGrip arm is the reason this robot exists, and buyers find it genuinely fun: it can pick up socks, slippers, crumpled tissues and some small pet toys, move them aside or drop them in a designated spot, and it pairs with neat extras like a first-person video-call and remote-drive mode and pet-finding features. But owners are candid that it is still early technology. Object recognition can be slow, the list of things it reliably handles is short, and more than one reviewer calls it a party trick rather than a personal maid. More importantly, the arm is the single most common reliability complaint: several owners report it getting stuck extended or ceasing to work after a few weeks or months, in some cases requiring the unit to be sent in for repair or replaced. Treat the arm as a bonus that should improve through software updates, not the main reason to buy.
What to know before you buy
The biggest caveats are reliability and price. Beyond the arm issues above, a few owners hit Wi-Fi drop-outs mid-clean or units that needed servicing, and experiences with customer service and spare-part availability are mixed, though many found support responsive. The onboard dustbin is small because the arm takes up internal space, so the robot leans on the dock to stay ahead of a full bin. Long hair can still tangle and clog the roller, and because the robot holds a water tank it cannot be flipped over, which makes clearing a clog awkward. The app draws some gripes: occasional lag, and no way to delete phantom rooms created by floor-level mirrors or glass. As with any robot it can snag on cords or small towels and misses tight corners and spots behind doors. Finally, it commands a very high price at full retail, and it does not include floor-cleaning solution, so budget for a robot-safe cleaner and expect some hands-on upkeep.
Is the Roborock Saros Z70 worth it?
If you want the most advanced robot vacuum you can buy and your home is mostly hard floors, it is hard to top: the suction, hot-water mopping, StarSight navigation, slim under-furniture body and self-maintaining dock add up to a genuinely excellent cleaner, and the arm points at where the category is heading. The catch is value and reliability. Owners are split on whether it justifies its flagship price, with the common view being that it makes sense on one of its frequent steep discounts rather than at full price, and the arm reliability reports mean it is a better fit for early adopters than for someone who just needs a dependable set-and-forget machine. Buy it for the cleaning and the cutting-edge features, view the arm as a bonus, wait for a sale, and budget for a robot-safe floor cleaner and regular maintenance.
Frequently asked questions
Does the Roborock Saros Z70's robotic arm actually work?
Yes, but treat it as a bonus. The OmniGrip arm can pick up socks, slippers, crumpled tissues and some small toys, move clutter aside and even video-call or be driven remotely. However object recognition is slow, the list of items it reliably handles is short, and it is the feature owners most often report problems with, including jamming or stopping after a few weeks. Roborock expects it to improve through software updates.
Is the Roborock Saros Z70 good at mopping?
Yes, mopping is one of its strengths. It uses dual spinning mop pads with hot water, extends a pad to reach edges, auto-lifts the mops on carpet, and washes and dries them at the dock. Owners say hard floors come out noticeably cleaner and that the dirty-water tank shows the mops are actually removing grime.
Which smart home platforms does it work with?
It works with Amazon Alexa, Google Home, Apple Home, Matter and Home Assistant, and it can be controlled through the Roborock app or its built-in voice assistant. It connects over 2.4GHz Wi-Fi only, with no 5GHz support, and there is no IFTTT integration.
Does the Roborock Saros Z70 require a subscription?
No. Vacuuming, mopping, mapping, scheduling, no-go zones and the app features all work without any paid plan. The main ongoing costs are consumables such as dust bags and mop pads, plus a robot-safe floor cleaning solution, which is not included in the box.
How does it handle pets and long hair?
It is strong on pet hair and includes pet-friendly extras like obstacle avoidance around pets and a pet-finding mode, and owners with dogs are generally happy with the cleaning. That said, long hair can still tangle and clog the roller, so plan on regular maintenance, especially in homes with shedding pets or long-haired residents.
Is the Roborock Saros Z70 worth the high price?
It is one of the most advanced robot vacuums available and cleans like a flagship, but value is the biggest debate among owners. Many feel it makes the most sense on one of its frequent steep discounts rather than at full retail, particularly given that the headline arm is still maturing. If you want cutting-edge features and mostly hard floors, it delivers; if you mainly need dependable, no-fuss cleaning, a cheaper model may serve you better.
