Viomi alpha - S9 - self cleaning vacuum cleaner?! Full walkthrough review [Xiaomify]

The Viomi S9 is the latest model of Viomi's vacuum and mopping robots. It has improved from their latest flagship model the V3 in terms of battery, suction strength and the water tank seems to have gotten improved on this one as well. Other improvements include a better loudspeaker for voice prompts (not all that needed) and more importantly it's a lot more silent when it's vacuuming, comparing it with the V3 as well.

The diposable dust bag makes it a dont-buy for me.

Please test Xiaomi Lydsto R1 and Xiaomi Roidmi Eve Plus

[allotmental.]

I'm guessing it cannot do corners as it's round 😂

[ΝεκταριοςΑποσπορης]

In comparison with the roborock s5 max is better?

[debur]

Great video again like always. Keep up the good work ✌.

[justtherecord]

no more viomi for me. my brand new x2 still cant find its way to the dock after finishing the cleanup. been waiting for a firmware update like forever now but even after that it might not work right. i'll stick with roborock

How often do you need to replace the bag? Or asked differently, how many minutes of cleanup does it take to fill the bag up? Does the app remind you of replacing the bag when it's full, or do you have to check by yourself?

Hey did you happen to see that announced Roborock S7. And if yes would love to see a test

[ssac]

im waiting for the version with vaccum that empties the bucket that vacums from cleaninng vacum... Xzibit edition ! :P

[bradleydibble]

Does it detect cartets and rugs when mopping and avoid them.

[JAKOB]

How well does it empty the bin?.. I reckon it varies from what materiel is has consumed.
and how does the rollerbrush handle hair or strains?
but all this with automatic suctinh and empty the bin.. not really something I will prefer.
on a normal vacuum cleaner.. it's okay that the bag is closed and you can't see it, as you after all have micromanaged the cleaning yourself while going around with the vacuum.. but these automatic, its another ballpark, as you have no insight what it has eaten.
We have had the Xiaomi 1G model for many years, and it still rolling solid.
but I have also found some of my girl's jevelery that likely was hidden under the sofa or bed, and other things that I was glad I could overwatch and notice while emptying the bin so it didnt was thrown out.
so on an automatic robot vacuum.. I certainly like that I can see what I'm throwing out when emptying the bin.

very expensive, its more than enough with my 3 years old xiaomi mi robot vacuum 2nd version hehe. thanks for the video

[MisterEE]

This is on promotion where I live, I am tempted to buy it. As for comments about bags, I am also confused why they are bags? Everything now a days (including the robot) has a plastic cylinder to collect rubbish and you empty it, so why are there bags on even the most premium vacuum robots?

Excellent review as always! But the disposable dust bag in 2021 is unacceptable. We need to reduce the waste in the environment.

[laurynas]

Hi. When I start mopping, I don’t see any water on the ground. I think that mopping is not working. Or maybe I shouldn’t see anything? Would appreciate some help, thanks

[JoaoPiresPT]

I know that might be a stupid question, but I’m not be able to set the map as I want, like showed in the video, there is any trick? Or should I have to go with the vacuum room by room with the charger and do the mapping?

[jaikaranthakur]

Should I always keep robo cleaner and station on or should I keep it off to extend the battery life of robo cleaner???

[TheSfj]

Great review, just have one question. My not so older V2, always have problems with mopping tiles / ceramic at kitchen, this version it is heavier or have more traction on the wheels? ( My V2 with tiles wet keeps skatting same place and troubles getting around) many tanks

[orangedan]

I'm really confused about all the different modelling number by Xiaomi. I thought the s7 is the next gen by Xiaomi. So what's this s9? Is it the same unit? Just for different region?

[catalinalucianabajanaru]

Hello, I'm currently looking for a robot vac and I was almost set on Roborock S5 Max, but I like the idea of self cleaning dustbin. So, which would you recommend between Roborock S5 Max, this one and the Roidmi Eve Plus? What are the differences between these models. Thank you
