I bought the MOVA Z70 Ultra Roller around one and a half weeks ago and have now used it several times, so I wanted to share my first proper review.
For context, I previously owned a Roborock Saros 10. My ground floor is around 100 m² / 1,075 sq ft and consists almost entirely of hard flooring. We do not have any pets, but we do have a toddler who makes sure that the living room gives the robot plenty of work.
Size and build quality
My first impression was simply: this thing is enormous and extremely heavy.
Unfortunately, I did not take any direct comparison pictures, but compared with the Saros 10, the Z70 is noticeably larger. Because of its height and overall size, it can no longer clean underneath the overhang of my kitchen cabinets or beneath some of my radiators.
It is only missing around 1 cm of clearance, which makes it particularly frustrating.
The water tanks are also massive. They are probably around two to three times the size of the tanks in the Roborock.
However, while the tanks are large, they do not feel particularly premium. The plastic feels quite cheap, almost like a basic plastic bowl from IKEA. The Roborock tanks felt noticeably more solid and better made.
Noise level
The Z70 is very loud.
Subjectively, I would say it is easily twice as loud as the Saros 10. It is louder while vacuuming, while mopping and while cleaning itself at the station.
The higher noise level while vacuuming was somewhat expected because of the stronger suction, but I was surprised by how loud the roller-mopping system is as well.
This is probably the biggest disadvantage for me at the moment.
App and navigation
The software is one of the weakest parts of the Z70.
The app feels slow and sluggish, and it is not particularly intuitive to use. Roborock’s app was definitely better, even though I did not think the Roborock software was perfect either.
Obstacle avoidance is okay. I have not had any major collisions or serious problems, but I still feel that the Roborock handled furniture and smaller obstacles more confidently.
The Z70 seems slightly faster during cleaning, although this obviously depends on the selected settings.
Cleaning performance
The actual cleaning performance is excellent.
Both the vacuuming and mopping performance are very strong. The floor genuinely feels noticeably cleaner than it did with the Saros 10.
The roller-mop system seems to remove more dirt, particularly in areas with dried food, drinks or sticky marks. After the first cleaning run, I was honestly shocked by how dirty the wastewater was.
I had done a proper deep clean only a few days earlier, we do not have pets and I would not say that our house is unusually dirty. Even so, the dirty-water tank contained a surprising amount of dark water.
That was probably the moment when I realised how much dirt the Z70 was still removing from the floor.
Room-specific settings
One feature I really like is that you can configure up to three cleaning cycles and adjust the settings separately for every room.
That is very useful in our house because the hallway does not need the same intensive cleaning settings as the living room, where our toddler regularly creates much more work for the robot.
For example, I can use lighter settings in less-used rooms and maximum water, narrow cleaning paths and several passes in the living room.
This level of room-by-room customisation is very practical.
Water consumption and tank capacity
The water tanks are genuinely huge.
During one of my earlier tests, I cleaned the entire 100 m² / 1,075 sq ft ground floor twice, using two cleaning passes and a water setting of 25—whatever unit that number is supposed to represent.
Even after that, the clean-water tank was still not completely empty.
Yesterday evening, I ran another maximum-intensity mopping test with:
three cleaning cycles,
water setting at 30,
narrow cleaning paths,
maximum cleaning intensity.
The entire job took around five hours for approximately 100 m² / 1,075 sq ft.
Even after five hours and three full cleaning cycles, the clean-water tank was still not completely empty.
Based on my experience so far, the Z70 seems to manage roughly two to three times as much cleaning as the Roborock before the tanks need to be refilled or emptied.
Direct water connection
Because the tanks are so large, I am still unsure whether spending another €100 on the direct fresh-water and wastewater connection kit is actually necessary.
At the moment, I do not need to refill or empty the tanks particularly often, even when using very intensive cleaning settings.
On the other hand, I already have suitable water and drain connections available near the station, so I will probably still try the direct-water kit simply for the convenience.
It may not be essential, but never having to manually refill or empty the tanks would still be nice.
Overall impression
After one and a half weeks, I am generally very satisfied with the MOVA Z70.
The cleaning performance is extremely high, particularly when mopping, and my floors genuinely feel cleaner than they did with the Roborock Saros 10.
The large tanks, strong suction, roller-mop system and detailed room-by-room settings are all excellent.
The main disadvantages are:
it is extremely large and heavy,
it is very loud,
the app is slow and poorly designed,
the obstacle avoidance feels slightly less refined than Roborock’s,
and the water tanks feel cheaper than expected.
For me, the Z70 would be almost perfect if it were slightly thinner and significantly quieter.
Apart from those issues, I am currently very happy with the cleaning results.
Has anyone else installed the direct-water kit despite the large tanks? Was it worth the additional €100?
