Narwal Freo Z Ultra Robot Vacuum and Mop two-minute review
Launched to great acclaim at Europe’s biggest tech show, IFA (where it snagged two awards), the Narwal Freo Z Ultra is a successor to the brand’s Freo X Ultra. Significant upgrades include dual RGB cameras, LiDAR navigation, and an increase in suction power from 8,200 to 12,000Pa. In layman’s terms, it’s better at obstacle avoidance and adaptive cleaning, plus it sucks up more dirt!
In my tests, I found the Z Ultra excelled at both mopping and vacuuming on hard floors (of which I have many) but it was less cool on carpet. To be fair, I’ve tested some of the very best robot vacuums and am yet to find one that can handle dusty carpets as well as the best manual vacuums for carpet, which always have more power and better filters.
I loved all the smart automation, which meant I didn’t have to zone off carpets to stop them getting soggy or worry about what power level or speed to set. As a germophobe I also really appreciated how hygienic this robot is; cleaning and drying itself after every session.
Its mapping powers were also great, but I would have liked a quick option for spot cleans. Many robots allow you to mark a zone on the map where there’s a spill and send the robot straight there to clean. The only way I could work out to do this was in video mode, where you can manually navigate the vacuum. The issue here was the video was glitchy about connecting and often flatly refused – not ideal if you have spilt something that could stain and needs speedy attention.
I also had a few bin-related issues, and mopping was deadly s-l-o-w, but absolutely worth the wait. Ideal for large homes with mostly hard surfaces, the Narwal Freo Z Ultra suits tech-savvy homeowners who appreciate an integrated app and can get their head around fine-tuning settings. Technophobes and the impatient (and anyone on a budget) might prefer to steer clear.

Narwal Freo Z Ultra review: price & availability
- List price: $1499.99 / AU$2,499
- Launch date: October 2024
- Availability: US / AU
The Narwal Freo Z Ultra launched in October 2024 and at time of writing is available to buy in the US and Australia, with a list price of $1,499.99 or AU$2,499. That places it firmly in the premium price bracket. There’s no getting away from it, the Narwal Freo Z Ultra is a pricey robot vacuum sitting at the very top of the market in both Australia and North America. You can save a few dollars by waiting for seasonal sales (the Black Friday deals often include some big robovac price-drops).
There are two accessories pack options. Option 1 will set you back an extra $259.99, and costs of a whole raft of brushes, detergents, dust bags and mop pads. Option 2 gets you a few of the most-used accessories, for $100. You can also add a one-year extended warranty plan for $79. Buying the accessories individually will soon add up – a replacement detergent is $29.99 – so it’s worth doing the math before you decide which option to start with.
While the Narwal Freo Z Ultra is an investment appliance, it will save you a LOT of time and it’s by far the best mopping robot I’ve tested. I wouldn’t buy it purely for vacuuming, but as a combo, it might be worth the spends.

Narwal Freo Z Ultra Robot Vacuum and Mop review: design
- Stylish robot with mopping and vacuuming skills
- Large mop heads and spinning brushes for getting close to edges
- Decent capacity water reservoirs
Arriving in a huge box, I needed an extra pair of hands to unload the Z Ultra and was grateful for the hand grips in the base station when positioning the heavy unit next to a power point. It comes with a simple instruction card for first-time setup, as well as a more comprehensive user manual. I used the former to install the side brushes, insert the detergent and add clean water. My daughter got a lot of satisfaction from removing a gazillion instructional stickers from both the base station and vacuum unit.
The design of the Freo Z Ultra, and base station, is very stylish indeed, which is just as well given that it’s hard to hide! Choose from Galaxy White or Space Gray. All the edges are softly curved and, with its two camera ‘eyes’ in the front, has the cute vibes of Pixar’s Wall-E, which is exactly how I like my robot vacuums. The various lids and covers pop off without breaking any fingernails, and everything is easy to access.
Underneath, this robot has two large microfibre style mops that Velcro on, as well as two rotating side brushes that are a good length for getting into corners. The main roller brush has a rubber flipper part as well as brushes to suit both hard floors and carpets, plus its anti-hair tangle design does actually work. As I have two daughters and two spaniels who seem to molt year-round, I was delighted to swerve the odious task of cutting swathes of hair from around a roller. (Effective anti-hair wrap brushrolls are a key feature amongst the best robot vacuums for pet hair.)
One unusual feature I’ve not seen anywhere else is a fluffy baseboard duster that attaches with Velcro on one side and is designed to gather dust from the tops of your skirting boards as it goes along the edges of the room
The Narwal Freo Z Ultra’s base station has two large containers for clean and dirty water. These are are easy to lift in and out, but you’ll want to make sure the dirty water reservoir’s lid is properly clipped on, or you may have to clean up a mini flood.
There’s also a dust collection bag and compartment into which to slot the bottle of floor cleaning solution that’s supplied. The bot does work without the detergent module in place, which is handy given they cost nearly $30 a pop. There’s a cool little window strip in the base that shows the water being ionized. It’s not clear why the water needs to be ionized but if you like watching bubbling water, take a peek.
Narwal Freo Z Ultra Robot Vacuum and Mop review: performance
- Amazing at obstacle avoiding and navigation
- Great at mopping, poor on carpet
- Self-cleaning is great, but self-emptying hit and miss
The first job any robot vacuum has to complete is a map of the house, which this little beauty did in 17 minutes – impressive given we have quite a few little rooms, and many obstacles. (Here’s more on how to prepare your house for a robot vacuum, if you’re unsure.)
The mapping was precise and accurate. I liked how the map shows where the rugs and carpets are; often you have to add your own, which requires some guesswork on precise positioning. I’ll discuss the App in more depth later, but it was easy to name each room and set up no-go zones and divide rooms. Another bonus of the Freo Z Ultra is the ability to choose from a wide menu that covers mop, vacuum, mop & vacuum, and mop then vacuum. Some models I’ve tested don’t allow you to just mop.
Once I’d got to grip with the controls, I loaded up the water tank and tasked the Freo Z Ultra to vacuum and mop my entire ground floor, which is mostly engineered wood, with some terracotta, porcelain, luxury vinyl and of course rugs and carpet. Pretty diverse then.
While it was possible to set my own cleaning parameters, the Freo Z Ultra has an AI mode that uses various sensors and cameras to automatically adapt to different floor types and dirt levels. This takes the brainwork out of setting up and ended up being my go-to mode throughout my three-week trial period.
The first thing I noticed was how good the Freo Z Ultra was at obstacle avoidance – no banging into furniture or corners and no dragging cables or dog toys around the floor with it. (TechRadar’s article on how robot vacuums navigate walks through the typical approaches brands use.) I never once got a message to say the roller brush was stuck, which is the usual warning that a robot has eaten something it shouldn’t! It was also excellent at powering over thresholds and the annoying chair legs I have that robot vacuums usually get grounded on, and spin like mad until sending a stuck error message.
The second thing I noticed was how it doesn’t get terribly close to the edges in mopping mode. When vacuuming, I could see the little spidery side brushes pulling dog hair and dander in from the edge but in mop mode there was a clear inch or more of bone-dry flooring around the perimeter of the room and any floor-level furniture like our kitchen units and sideboard.
And on the subject of edges, I’m sorry but the little fluffy baseboard duster on the side of the robot is only going to work if you have super low baseboards. Like many heritage properties, the baseboards in our Victorian home are quite high so it doesn’t reach the tops, aka the only bits that need dusting.
The Freo Z Ultra doesn’t carry any water onboard, which is unusual. Instead, it loads its mops up with warm, soapy water at the base station before heading out to clean. I was concerned this would result in dry patches of flooring, but the dampness levels were perfect – not too wet (important on real timber flooring), nor too dry.
The only downside is it has to make repeat returns to load up with more water, which can elongate the cleaning time, especially in rooms that are furthest from the base. For example, it took 1hr 19mins to mop our utility and hallway, which is an area of just 40 sq m. To vacuum and mop the whole ground floor, 68.3sq m, the Freo Z Ultra took a tedious 2h 41mins. Imagine how long it would take if I asked it to vacuum and then mop, rather than do it consecutively. I didn’t want to find out! I’ve never tested a robot that spends longer than two hours on the job.
When the robot returns to base after mopping and vacuuming, it automatically empties the bin and cleans its mop heads and then dries them. The latter takes a couple of hours but it’s incredibly quiet, so you won’t notice it. I did have to set the bin emptying to every run on the app, otherwise it clogged up and couldn’t self-empty itself. Hardly surprising given how microscopic the onboard bin is. Even then, there were a few times the bin just wasn’t self-emptying, even though it said it was, which was frustrating.
There are a handful of extra features – perhaps the most interesting one being that in Video mode you can see through your robot’s ‘eyes’ and remote control it around your home. That means you can use it as a security bot, or to check up on pets and send it off to specific locations. This mode isn’t authorized by default, you’ll need to manually switch it on if you want to use it.
Cleaning tests
When it came to running our standard vacuuming tests – one using a fine mix of biscuit and flour, and another using oats to represent larger particles – the results were a mixed bag. The Freo Z Ultra did well on the hard floors, eventually anyway. It took at least three passes and full power mode to get everything up.
I used multiple ‘no-go’ zones on the map to create my 1m x 1m test area, but the robot still seemed to spend far longer cleaning around the area I had made my test spills than it did actually dealing with the mess. This led me to seriously question Narwal’s claims that it homes in on and targets dirt using its beady little cameras and sensors.

With oats on carpet, the results were middling. The robot pushed things around a fair bit and it took three runs before they were gone. The dog may have helped!

On carpet, the fine mix removal was very disappointing. I gave up after three attempts and got my cordless vacuum out. Although this isn’t great news, I’d argue that it’s not often you’ll experience this level of concentrated ‘dust’ and I was always happy with its carpet cleaning results in general.

Next, I tried out the mop function by ‘spilling’ first Ribena juice and then ketchup, which I left to dry, on the porcelain tiles in our cloakroom (I didn’t want to risk stains on our timber floors). These results were much better, although the dried-on ketchup required two passes to complete the job. According to Narwal, this impressive mopping is achieved via dual rotating mop heads that press down with 1.2kg of force and spin at 180 RPM. Other robot mops I’ve used either just drag a static mop pad along, or have a vibrating mop, this spinning tech is the closest I’ve come to mimicking real mop work. And the results show it.
Apparently, this robot also analyses the waste water to decide if another cleaning run is required but I had to make that decision myself with the ketchup; the Freo Z Ultra thought it was done after one attempt.

To check navigational skills, our final test involves placing a sock (in a similar shade to the flooring) a shoe and a charger cable on the floor. The Freo Z Ultra absolutely nailed this test, not touching any of the objects but getting close enough to clean sufficiently around them.
The Freo Z Ultra takes around 2.5 hours to charge, which is a bit speedier than normal, and has a run time of just over 2 hours 15mins (in vacuum and mop mode), which is about the standard for a high-end robot. It automatically returns to the base to charge if it runs low on juice during a cleaning cycle, which is also the norm. If I was asking it to do the whole house, it never managed on a single charge but I usually tackle the dirtiest rooms (kitchen and hallway) more frequently and that was easily done without the need to stop to recharge.
Noise-wise, I am quite noise intolerant and as I work from home, I don’t like having noisy robots rattling around the house while I am trying to focus. Happily, I found the Freo Z Ultra one of the quietest robots I’ve tested, especially in mopping mode, with my decibel meter App recording between 60-70dB max. This is way below the noise levels you would get from a regular vacuum, but if they still bother you, just schedule the robot to work while you’re out of the house.
Maintenance
I found the Freo Z Ultra easy to clean and maintain, the internal bin pops out for emptying, if it hasn’t emptied automatically into the base station, and the mop heads are automatically washed with hot water and dried after every use. This is important to prevent bacteria breeding in the mop heads and before being dragged all over your home. All this self-cleaning did mean it rattled through the clean water in the tank and I had to refill it before most cleaning runs, but that’s a small price to pay I’d argue.
Like all robot vacuums, it’s important to keep the sensors and charging contacts clean, which is an easy wipe-over task. The roller brush didn’t clog in the three-week test period, but if they had, they do clip out very easily. I also didn’t fill the dust bag in the base station but it just clips out and pops straight in the bin when full.
Narwal recommends cleaning the filter once a week, which involves clipping it out from under the top cover on the robot and tapping out the dust – simple. It should be replaced every three-six months.
- Performance score: 3.5 out of 5
Narwal Freo Z Ultra Robot Vacuum and Mop review: app
- Very easy to work out without assistance
- Lots of options to customize cleaning (or not)
- Mildly glitchy connection
The Narwal Freo Z Ultra app is user-friendly and intuitive (I never needed to use the Help Center), making it easy to create custom cleaning schedules, adjust settings, and monitor cleaning progress in Real Life. Make sure you connect using a 2.5GHz wi-fi link, not 5GHz.
If you love an easy life (as I do), you can clean in Freo Mind mode, which leaves all the decisions about power levels, patterns and passes to the robot. If you’re a control freak, each cleaning program comes with various adjustment options, such as mopping humidity, coverage precision, detergent use etc.
You can choose which rooms to clean, but I also liked that I could set the cleaning sequence for a full home clean. For example, I set it to start in the kitchen, then hallway, then dining room (where my desk is), so that it gets those rooms I spend most time in done first (while I’m taking the kids to school). You can also split rooms, merge rooms and add no-go zones.
The app also provides cleaning history and notifications to ensure you stay informed of cleaning progress. I did experience quite a lot of delays between opening the app and the robot syncing, but we’re only talking seconds. And it often annoyed me that there was no Spot Clean option but that may well come with a software upgrade.

How I tested the Narwal Freo Z Ultra Robot Vacuum and Mop
I tested the Narwal Freo Z Ultra Robot Vacuum and Mop for three weeks on the ground floor of my four-bed historic home. With the exception of thick-pile carpet, we have all manner of flooring types from porcelain and terracotta tiles to vinyl and engineered oak. I ran the robot in various rooms, in every cleaning mode, every day and tried cleaning in both automatic smart mode and fully customized. I also set schedules and conducted controlled tests where I had the robot vacuum flour, crushed biscuits and oats from hard floors and rugs, as well as mop wet and dried on spills from the porcelain tiled floor.
