Freo Z10 Ultra
2 independent reviewsRead the findings →Narwal's 2025 spinning-pad flagship, with a mop that swings out to reach skirting boards. It's one of the best moppers around and dodges clutter well. It can be unreliable at finishing jobs and emptying itself, though.

What reviewers found
Two home tests: TechRadar over a couple of weeks in a house with a dog, and techreviewer in an 80-square-metre flat. Both rate the mopping among the best they've seen and both found obstacle avoidance excellent. Both also found vacuuming solid rather than outstanding, with carpet and edges its weak points. Reliability is the big difference: TechRadar had skipped rooms, failed bin emptying and a confusing app, while techreviewer reported none of that.
TechRadar, hands-on, A couple of weeks at home, Dec 2025 · techreviewer, hands-on, Sept 2025
Hard floors
Mixed resultstechreviewer found it performed exceptionally on hard floors, with crumbs and cat litter reliably gone. TechRadar found everyday crumbs and pine needles fine, but fine biscuit and flour still weren't cleared after three passes on maximum, and edges under kitchen cabinets were missed.
Carpet and rugs
Mixed resultsSolid rather than outstanding. techreviewer found it vacuums carpet well but leaves more deep-down grit than top Roborock or Dreame models, and TechRadar saw fine particles ground into a medium-pile rug.
Pet hair
Reviewers rate it highlyWith a fluffy Keeshond, TechRadar found it cleared dog fur well and the anti-wrap roller a boon. techreviewer found the conical brush picked up hair without tangling.
Mopping
Reviewers rate it highlyTechRadar rated the mopping up there with the best it had seen, reaching right up to walls, and techreviewer saw coffee and sauce usually gone in one pass. TechRadar found the automatic mode missed a puddle and dried ketchup, so set it manually.
Navigation and obstacles
Reviewers rate it highlyTechRadar found it avoided its dog, cables, shoes and furniture in a cluttered home, needing rescue only a couple of times. techreviewer saw it reliably detect cables and socks, and mapped an 80m² flat in under five minutes.
Dock and upkeep
Mixed resultstechreviewer found the pads washed and dried reliably with no odours and the tray quick to clean. But TechRadar couldn't get the bin to empty consistently, and both found it gets through clean water quickly.
App and software
Mixed resultstechreviewer found the app extensive and useful, with a live camera and photos of avoided objects. TechRadar found it overwhelming, with key settings such as carpet vacuuming buried, and had to look up basic tasks online.
Noise
Not enough evidenceOnly TechRadar measured it: about 60dB while cleaning, which it found tolerable, but nearly 80dB when the dock empties. No other review we use measured noise.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term. In two weeks, TechRadar saw it skip rooms and fail to empty its bin, while techreviewer reported no such faults.
Value
Not enough evidenceOnly TechRadar judged value, finding the feature list worth the price on paper but its unreliable behaviour a possible deal-breaker unless heavily discounted. techreviewer flagged only the cost of detergent cartridges.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Mopping is the main attraction
TechRadar called the mopping up there with the best it had seen, handling muddy paw prints, food spills and a large dried ketchup stain on the wettest setting. The extending pad reached right up to walls. techreviewer found coffee and sauce usually gone in one pass, with grease needing two or three, and a narrow strip sometimes left in very tight corners. If hard-floor mopping is your main chore, this is the reason to buy it.
Reliability split the two testers
TechRadar often sent it to clean and saw it skip whole rooms, or roll out of the dock and straight back. It couldn't get the dock to empty the bin consistently, and it ignored rugs and carpet until each one was switched on in the app. techreviewer reported smooth running and no such faults. Neither review explains the difference, so run full cleans early and check which rooms were done and whether the bin emptied.
Excellent at avoiding clutter
TechRadar found it steered round furniture, cables and shoes, and only needed rescuing a couple of times in a cluttered home. techreviewer saw it reliably detect cables and socks, and liked that the app shows photos of what it avoided. One quirk: techreviewer's robot mistook a flat, dark plastic mat for carpet and lifted its pads there. Treat it as one of the better robots for a lived-in floor.
Vacuuming is decent, not great
TechRadar found it cleared dog hair, pine needles and crumbs well in everyday use, but missed debris along edges under kitchen cabinets and struggled with larger spills even on full power. techreviewer rated it excellent on hard floors and good on carpet, though it left more deep-down grit than top Roborock or Dreame models. Both praised the tangle-free brush. For heavy carpet cleaning, look elsewhere.
Thirsty in automatic mode
There's no water tank on the robot, so it keeps going back to wet its pads. TechRadar had to refill the dock more often, and techreviewer saw it empty the whole 4.5-litre clean tank in one run of a small flat in automatic mode. Setting the water level yourself cuts that down. techreviewer also flagged the ongoing cost of Narwal's detergent cartridges.
This covers the Freo Z10 Ultra. The cheaper Z10 Turbo and the older Freo Z Ultra are different robots.
Our take
Should you buy the Freo Z10 Ultra?
Best for: Homes where washing hard floors is the main job. Skip it if: You want simple setup with little time spent adjusting maps or settings.
Mopping is its strongest reason to buy, but one reviewer repeatedly found rooms skipped and dust left in the robot after emptying. Those are substantial drawbacks if you want cleaning to run with little attention. The Qrevo Curv 2 Pro is worth comparing for carpet and low furniture, although its own reviews found weak small-object avoidance.
The Freo Z10 Ultra follows the Freo Z Ultra at the top of Narwal's spinning-pad range, and its new trick is a pad that swings out sideways to reach edges and corners. The robot carries no water of its own, so it keeps returning to the dock to wet its pads, and the dock empties the bin, washes the pads in hot water, dries them and doses detergent. It stands about 11cm tall with a raised sensor that cannot lower, so it won't fit under low sofas.
Both testers rated the mopping among the best they had seen. TechRadar saw it shift muddy paw prints and dried ketchup, and techreviewer found coffee and sauce usually gone in one pass. Both also found it excellent at avoiding cables, shoes and socks. Vacuuming is only decent: techreviewer found more deep-down grit left in carpet than top Roborock or Dreame models, and TechRadar saw edges under kitchen cabinets missed. The testers split on reliability. TechRadar had it skip whole rooms and fail to empty its bin, and found the app overwhelming, while techreviewer reported no such faults. Both found it drains its clean water quickly in automatic mode, and techreviewer flagged the ongoing cost of detergent cartridges.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
It's better than most. TechRadar found it avoided cables, shoes and clutter, and techreviewer saw it reliably spot cables and socks. Neither tested real pet mess, so still keep an eye on the floor if your pet has accidents.
Does it fit under low furniture?
Not the lowest. techreviewer measured 10.96cm, and the laser turret doesn't retract. TechRadar found it too tall for some low furniture. Measure the gap; robots with a pop-down turret get under about 8cm.
How often do I have to empty or refill anything?
Water is the main job. techreviewer saw it drain the 4.5-litre tank in one run on automatic, so set the water level manually if you'll be away. The dock empties dust into a 2.5-litre bag, per the specifications, though TechRadar couldn't get emptying to work consistently.
How does it protect carpet from the mop pads?
It lifts the pads 12mm when it finds carpet, per the specifications, and techreviewer confirmed rugs stayed dry. TechRadar warns that carpets and rugs are skipped during vacuuming until you enable each one on the map, so set that up straight away.
Does it need a subscription or an account?
You use the Narwal app. TechRadar found basic tasks hard to locate, while techreviewer liked the extensive controls and PIN-protected camera view. Neither review says whether every feature needs an account or an extra payment, so check Narwal's current terms if either would put you off.
Alternatives
Other robot vacuums to compare.
Flow 2
Why consider it: After months at home, testers found it left clean, streak-free floors with no trouble from hair.
The compromise: It missed cereal and debris along edges, had some docking frustrations, and its app takes getting used to.
Qrevo Curv 2 Pro
Why consider it: Its vacuuming on carpet is widely praised, and it's slim enough to slide under low furniture.
The compromise: Home reviewers were cooler on its spinning-pad mopping and on how it handles small objects.
P50 Pro Ultra
Why consider it: Easy to recommend for hard floors, with extending tools and a big dock that make routine cleaning convenient.
The compromise: Lab results on deep carpet cleaning conflict, so don't count on it for pet hair in carpet.
