Overall Rating: ★★★★☆ 4.7/5
In this Roborock Saros Z70 review, we look at the first robo-vac that doesn’t just avoid clutter—it moves it. Roborock’s new OmniGrip arm can lift light obstacles (think socks, cables, toys) so the bot can actually finish the job it started. Pair that with 22,000 Pa suction, an ultra-slim 3.14-inch body that fits under sofas, and FlexiArm edge tools that reach tight corners, and you’ve got the most autonomous Roborock yet. The dock hot-washes and dries mop pads, cutting day-to-day maintenance to almost zero.
If your home has kids, pets, and constant floor traffic, the Z70 aims to be a true set-and-forget cleaner. Below, we cover setup, object handling, vacuum and mop performance, dock upkeep, value, and quick comparisons—plus the pros and cons to help you decide if the Saros Z70 is worth the premium.
Quick verdict
If you’ve ever watched a robot pause at a sock, cable, or dog toy and give up, the Roborock Saros Z70 fixes that. It’s the first mass-produced robovac with a foldable five-axis robotic arm (OmniGrip) that can pick up small items (up to ~300 g), set them aside, and come back to clean once the path is clear. Pair that with 22,000 Pa suction, an ultra-slim 3.14-inch chassis, upgraded edge cleaning (FlexiArm on the brush and mop), and a dock that hot-washes and dries mops — and you’ve got the most autonomous floor system Roborock has built yet. It’s expensive and the dustbin is small, but for busy homes that want truly hands-off daily cleaning, the Z70 is the one to beat.
Who it’s for / who should skip
Buy it if…
- You want real automation (object handling + schedule and rules) in a home with kids, pets, and constant floor clutter.
- Edge lines bug you: FlexiArm side-brush and mop reach right into corners and along skirting.
- You want minimal dock chores (auto mop wash with hot water & drying, refill/drain).
Skip it if…
- You’re on a tighter budget (look at Roborock Q-series or S8 Max variants).
- You vacuum once a week and don’t need the arm/dock extras.
- You need huge bin capacity; the Z70’s integrated bin is small.
What’s new vs Roborock S8 MaxV Ultra
- OmniGrip robotic arm: picks up certain objects and can do basic “helper” tasks (place, move to box/rug), with user-definable items in the app.
- 22,000 Pa suction (S8 MaxV topped out at 10,000 Pa).
- Ultra-slim 3.14 in / 7.98 cm body for lower sofas and toe-kicks.
- AdaptiLift chassis + FlexiArm mop/brush for 0 mm edge reach claims and better corner coverage.
- Object AI: recognizes 108 object types and lets you add up to 50 custom definitions.
Specs at a glance (mobile-friendly)
- Suction: up to 22,000 Pa (HyperForce)
- Height: 3.14 in (7.98 cm) ultra-slim body
- Object handling: OmniGrip arm, lifts items up to ~300 g; 108 pre-trained items; add ~50 custom in app
- Edge cleaning: FlexiArm side brush & FlexiArm mop for edge/corner reach
- Navigation/AI: StarSight 2.0 (dual cameras incl. arm camera), LiDAR, enhanced obstacle avoidance
- Dock: hot-water mop washing (~80 °C), auto drying; refill/drain plumbing options on supported bundles
- Notable drawbacks: small dustbin (~180 ml); consumables add to long-term cost
Setup & daily use
- Map & teach: First run builds an accurate map; the Z70 also marks items it can lift and may return to clean once obstacles are moved. In the app, assign “homes” for socks/towels (e.g., “store box”, “entrance rug”).
- Rules & schedules: Create high-traffic routines (kitchen after dinner; entryway twice daily).
- Carpet care: Configure mop-lift rules for rugs/thresholds and boost suction on carpet. (Vacuum Wars measured mop lift and notes good auto routines.)
- Arm control: OmniGrip is off by default; enable in the app and test with supported items. You can manually control the arm/chassis from the app for a quick pick-up.
Cleaning performance
Hard floors
The dual rubber brushes and very high suction pull grit in a single pass; the FlexiArm side brush reduces that usual “dust line” along baseboards. The mop plates maintain even pad contact, and hot-wash at the dock keeps pads fresh between rooms.
Carpet & rugs
On low/medium pile the Z70 extracts embedded debris similarly to Roborock’s best, helped by the suction jump and auto carpet boost. The mop lift avoids wetting rugs during mixed floor runs.
Edge & corners
This is where it stands out: FlexiArm mop + brush extend into corners/edges and, paired with the arm’s obstacle handling, leaves less missed perimeter than typical round bots.
Object handling (the magic bit)
With 108 known items plus up to 50 you define, the bot can move light household obstacles (under ~300 g), then re-clean blocked areas. It won’t declutter a room of heavy stuff, but for socks, towels, sandals, tissues, charging cables, etc., it’s genuinely useful.
The dock & ownership experience
- Hot-wash (~80 °C) & dry keeps pads sanitary and reduces odor — a big improvement over cold rinses.
- Refill/drain (on supported setups) slashes weekly chores; you’ll mostly empty the small dustbin and toss the waste water when needed.
- Consumables: side brush, main brushes, filters, and mop pads are typical recurring costs.
Annoyances: The dustbin is on the small side (~180 ml), so homes with lots of pet hair may need to empty more frequently if you don’t pair the Z70 with an auto-empty accessory.
Value & price context
MSRP varies by region/bundle and has been reported at premium levels for a flagship with arm + advanced dock. If you don’t need the arm, Roborock’s S-series/Q-series can save a lot; but for people who want genuine automation and edge detail, the time saved is the sell.

Mini comparison (essentials only)
| Model | Best for | Standout | Trade-off |
|---|---|---|---|
| Roborock Saros Z70 | Busy homes w/ clutter, pets | OmniGrip arm, 22 kPa suction, ultra-slim, hot-wash dock | High price, small dustbin |
| Dreame L20 Ultra | Edge-focused mopping | Smart edge mop reach, powerful dock | Object handling not as advanced |
| Roomba j9+ Combo | Strong auto-empty; carpet | iRobot nav, dirt detect, big ecosystem | Edge/mop automation behind Z70 |
| Roborock S8 MaxV Ultra | Great all-rounder | 10 kPa suction, strong AI avoid | No arm; less edge reach |
Tips for best results
- Start tidy, then let it maintain: Teach a few item homes (socks→basket, sandals→mat). The arm gets smarter after you define your common obstacles.
- Two-pass routines: Program high-soil rooms for a second pass; Z70’s logic can also circle back after object handling.
- Mop care: Use the included/approved cleaning solution if supported; hot-wash keeps pads in shape, but swap pads for heavy mess weeks.
Pros & cons
Pros
- OmniGrip arm moves small obstacles so the bot can actually finish the job.
- 22,000 Pa suction + dual brushes = strong pick-up on floors and rugs.
- Ultra-slim 3.14″ body reaches under more furniture.
- Edge/corner reach with FlexiArm brush & mop; less “border dirt.”
- Dock hot-wash & dry for low-touch maintenance.
Cons
- Premium price compared with non-arm flagships.
- Small dustbin (~180 ml) means more frequent emptying without auto-empty.
- Object handling has a weight limit (~300 g) and needs app setup; it won’t declutter heavy items.
Can the Saros Z70 really pick up my kid’s socks and move them?
Yes — it’s trained on 108 object types and can move light items (under ~300 g). You can also teach up to 50 new objects in the app.
How “set-and-forget” is the dock?
Very. It hot-washes (~80 °C) and dries pads automatically and can be set up to refill/drain, so routine pad washing is hands-off. You’ll still empty the dustbin and replace consumables.
Is it safe around pets and kids?
Yes — the arm is off by default, has a weight sensor limit, and the robot includes child lock/emergency pause controls.
How tall is it? Will it fit under my sofa?
It’s 3.14 in (7.98 cm) tall, making it one of Roborock’s slimmest designs; measure your sofa clearance to be sure.
What’s the biggest gotcha?
The bin size. Heavy-shedding pets + daily runs may mean frequent manual emptying unless you choose a bundle with auto-empty (where available).
