Absolutely amazing! Working flawlessly for over a month, so far.
Color: White
I am very pleased with the performance so far. The strengths are the ease of setup, the accuracy of its mapping and carpet/floor recognition, the quality of its cleaning and mopping, and the entertainment of just watching. There are weaknesses. The documentation is sparse and pretty useless and tech support has been ghosting me..no responses. So hunt and peck with the App, mostly. Hard to really customize by trial and error. While it vacuums very well, it does not empty as well, really requiring the owner to manually empty the dust bin. No big deal. Maintenance recommendations are hidden on the website and I suspect it is advisable to do some maintenance after every use. The strengths win, however.

User friendly, Pet Hair Approved, Quite Powerful Robot Vacuum
Color: White
We prviously had an Eureka E10 vacuum and mop robot for 4 years. We had no idea what we were missing until we purchased this Narwal Freo X10 Pro.
It maps very fast.
It is extremely quite.
The vacuum then mop with a refreshed mop head solution is much better than dragging around a robot mop pad with no way to clean it without removing and washing it.
We have 3 Australian Sheppards that shed alot. This was the number one concern, whereas the prvious unit needed daily attention. Not a single hair tangle in the floating rotating brush of this unique Narwal Freo X10 Pro Robot vacuum.
4 months of no robot management is wonderful.
The application was easy to use with a ton of customizable options.
The AI option to recognize various floor types and throw rugs ensures a complete clean and quick simple setup.
Lastly the price vs product was very reasonable.
Great product! After spending many months researching, we are glad we made this investment.

After five months, it's basically a brick
Color: White
We've had this robot for five months, and it isn't durable. It worked fine for a couple months. But now it works fine for maybe 20 minutes and then just starts spinning around or going back in forth in the same area wasting its battery. The endless troubleshooting does not help. Cleaning all the sensors, resetting the robot, remapping the house ... Nothing helps. It is only being used in about 1100 sq ft of total space, so it's just not that complicated. It's been trying (and failing) to vacuum our smallish living room for nearly five hours, after several resets/etc. Back when it did function, the vacuum is rather loud if you want it to actually pick up anything big enough to see. The vacuum and mop are both terrible at inner corners, and the intersection between rugs and hardwood flooring is a total miss. There's like a 12" strip along all rugs where mopping never occurs. Definitely not a machine to be used without supplemental sweeping and mopping. The machine insists on starting rugs at the corner, so it pulls up even pretty heavy rugs sometimes. It's sucks up items like socks instead of avoiding them. Also, the machine has never successfully left alone no-vacuum rugs or no-go areas, so some rooms (like with high pile rugs or Christmas tree stands) just don't work without physical barricades. Really, really makes me miss the old reliable roombas...

This vacuum is a game changer
Color: White
Not all robotic vacuums are the same, and after testing so many of them in my life this one has outperformed the others hands down! From the suction power, to the battery life, and then the app I can't find a single thing I don't love.
The robot is and to pickup small crumbs, dirt, the typical messes, but most importantly it picks up kitty litter like it's nothing. This is an instant game changer. I no longer need to clean up after a robot. It's amazing!
The battery life is great! I have a 2500 sq ft house and it can handle all of it before charging. The "home base" makes this effortless where I just schedule my cleans and it takes care of the rest.
The app is really nicely built. It's simple and easy to navigate but it also gives me all of the advanced options such as invisible walls and no-go zones.
Overall, this is robotic vacuum is my new go-to and I look forward to using it for many years to come!

$500, not $600. It isn’t worth $600
Color: White
You’re gonna need to put on some glasses and grab a drink for this one.
Cons :
- Has issues with “muddy mats” brand rugs and mats, along with light mats
- It ate my socks
- Will molest your standing fans and shoes and pet toys
- Castor wheel is a hair magnet along with the “tangle less” floating brush
- Mop heads get dirty after just one run of the entire house
- It hates charging cables
- And dryer sheets
PROS:
- Smarter than Shark brand vacuums
- Excellent management of houses and avoiding most obstacles
- It mops and vacuums well
- Cleaning is very easy
- Cat litter gets sucked up on the strong setting (not the super strong, though that works too)
- Battery lasts for vacuuming most of the house
- No navigation issues
- Doesn’t mess up your furniture
- IT WORKS IN THE DARK
the floating brush though where the metal shaft sits inside the brush itself and the miniscule space between the spinning part and the brush itself gathers hair like a magnet and will give constant roller brush errors if not regularly cleaned. The castor wheel I swear has more hair than anything I’ve seen. Even the shark didn’t collect it this bad.
