Although this can be effective, I feel it is not enough, especially if you rely on it for scanning.
That’s where the Viomi V3 comes in – it’s the first robot vacuum/mop I’ve tested with a back and forth motion similar to the iRobot Braava.
Based on my tests, it does a great job of wiping stains off surfaces like tiles.
Is this the best robot vacuum/mop combo?
Viomi V3 review
Viomi V3 offers consumers a lot of versatility thanks to its ability to mop and clean floors thoroughly. You have the option to vacuum, vacuum and mop or just mop. In addition to the dust container, it also comes with a two-in-one container, and a 500ml water tank so you have more choices on how to use the robot. This model will work best on hard floor surfaces like hardwood or tile, but has a hard time on carpet (more on that below).

Introduction to Viomi V3
If you are not familiar with the Viomi brand, it is part of the Xiaomi Eco System. I think this model is similar to the Xiaomi Mop P. If you put these two side by side, you can see the similarities.
V3 is the latest Viomi model with more power, a bigger battery and the option to save up to 5 map levels.
This robot is unique to other brands I’ve tested because it can mop floors like the iRobot Braava – which means it moves in a back and forth motion.
The back and forth motion enhances its ability to remove stains on surfaces such as tiles.
Viomi V3 design
Elegance and simplicity are the first things that come to mind when you first see this robot.
The robot you got comes in all black color with shiny parts on top. At the top there is a LIDAR sensor cover engraved with the Viomi branding.
At the opposite end are the two buttons:
- residence: Directs the robot to return to the dock
- Clean/Energy: Turns the bot on or off and turns on the default power setting.
You’ll also notice the large door that reveals the matte black dustpan and the included brush cleaning tool.
The laser sensor comes in a neon blue color, which adds contrast to the design.
At the bottom, the robot has one side brush and the main brush is closer to the front from S5 Max.
Parts of the front wheel and main brush have a neon blue finish.
You will also notice a large number of holes behind the main brush – this is a placeholder for the erasing pad that covers more than 50% of the bot.
It’s a larger cushion than the S5 Max and S6 MaxV – the larger surface area helps it wipe better.
The V3 uses a more traditional side brush with bristle heads. I prefer the newer rubber side brush of the newer Roborock, which I think will last longer.
It doesn’t have a screw, so you don’t need a screwdriver to remove it – it only pops on pull.
Like the high-end robot vacuums Roborock and Xiaomi, Viomi also uses LIDAR and SLAM for mobility. It has an intelligent navigation algorithm similar to the other two tags you mentioned.
The laser sensor rotates continuously to determine its location and draw a map.
Begins to traverse the edges before cleaning the middle parts of the room with staggered back and forth motions.
Expect the same mobility as other robots that use LIDAR, such as NeatoRoborock, Xiaomi, 360, etc.
Unfortunately, it only goes around the area once by default. You will have to turn on the Secondary Cleanup feature in the app each time, so that it runs twice.
I hope Viomi will address this issue in future app updates – the option to add a third pass will be helpful for customers.
Will it break furniture Viomi V3?
There is little risk of scuffing V3 furniture. Two reasons. First, it slows down when it “sees” an obstacle and only pushes it.
Second, the front bumper has padding around it, which provides more cushion and keeps it from scratching things it hits.
I tested this by placing these two brooms in the middle of the room to see if the V3 hits them hard.
He didn’t and just gently pushed them.
How did you do in confined spaces?
One of the strengths of this robot is its ability to avoid getting stuck or lost under a maze of chair legs.
Not once did he get stuck under that office chair. She could easily get around him.
I would say it’s with the Roborock S-Series robot as the top choice when it comes to traversing small spaces.
Can wires be avoided?
Unfortunately, V3 will not avoid wiring. It does not contain the technology found in the Ecovacs T8 + that can avoid such obstacles.
App Features of Viomi V3
This robot is compatible with the Xiaomi Home app. I was expecting the same Roborock interface, but it was different. There are differences in the color scheme and layout. The map is in beige with a light gray border.
Below are six buttons – three in each row.
In the upper row:
- Pause/Dock: Instructs the robot to stop cleaning or return to the dock.
- Start: Enables the default cleaning cycle.
- Map: Shows users more options – Zone Editor, Default Wall/Restricted Zone, Fixed Clean, Clean Zone.
In the bottom row:
- vaccuum cleaner: The robot will only vacuum.
- Vacuum cleaner and mop: The robot will vacuum and mop simultaneously.
- wiper: The dump drive is turned off, and the robot just wipes.
Quickly browse through the most useful features of the Viomi app.
Virtual wall and restricted area
One of my favorite features is the virtual wall and restricted area. These two items provide users with a way to block the bot from restricted areas without having to use an object to physically stop the bot.
The virtual wall allows users to draw lines on the map to prevent the robot from entering areas beyond it.
So for our home office, it’s in this area.
You can set as many virtual walls as you like, so it is very convenient.
Restricted area is a similar feature, but it blocks the bot from a rectangular or square area.
It is useful to prevent the robot from mopping areas in your home with carpets or rugs.
Another option not found in Roborock S-Series bots like the S5 Max, S6 MaxV or S6 Pure The cleaning mode is selected.
Other LIDAR robotic vacuums only use an S-pattern or rectilinear staggered motions.
The Viomi V3 has two options – S mode for sweeping, and Y mode for mopping.
I like the Y style because of the back and forth motion that mimics how you mop floors. It provides better irritation, so it is more effective at removing stains than on hard surfaces.
Another useful feature is the region editor. It enables users to split each map into different regions. There is also an option to name each location on the map.
You can schedule the bot to clean certain areas at different times.
People can set an unlimited number of sessions per day. If you want a robot to clean your house every hour, this is possible with the app.
This feature somehow eliminates the lack of passes – the robot only spins once by default.
This function instructs the robot to clean the edges only. I don’t use this feature often because I want the robot to clean the entire area.
By default, V3 will only spin around the area once. If you want a more thorough run, you will have to turn on the secondary cleaning feature.
He tells the robot to take a second round, but the robot will not go further than two.
Be aware that this feature does not stay turned on. You will have to run it every time.
It shows you all the cleanings of the bot for the last 30 days, along with the corresponding maps.
It also provides information on cleaning time and area size.
The Viomi app allows users to save up to 5 map levels and can be accessed through the Maps menu section.
However, the process of creating a new map is not as straightforward as Roborock, providing you with a step-by-step guide.
With Viomi, it’s not that simple.
If you want to create a new map, first move the bot to a new location, then turn on the bot, then the app will ask you if you want to save the plan.
Make sure that the Memory Map option is enabled for saving maps.
This section provides users with the status of various consumable components such as filter, brushes and squeegee.
Displays the hours remaining before any of these parts need to be replaced.
One way to maximize the life of these components is to clean them regularly.
How noisy is the Viomi V3?
I measured the noise of the V3 with an audiometer a few meters away and here are the results.
- silent: 59.4 dB
- Basic: 62 dB
- Average: 64 dB
- Turbo: 66.4 dB
It exceeds 65dB and is louder than the Roborock S5 Max. There are no ear scratching levels, but you’ll know the robot is working even if you’re next door.
How much power does Viomi V3 have?
I used an anemometer to measure the airflow at the main cleaning head.
Here are the results.
- silent: 9.33 cubic feet per minute
- Basic: 12.32 cubic feet per minute
- Average: 14.2 cubic feet per minute
- Turbo: 17.10 cubic feet per minute
It’s a little less than the Roborock S5 Max, but it has more Best of the line S6 MaxV.
The airflow of the V3 is sufficient to clean up debris on hard floors. Unfortunately, it doesn’t translate well on carpet (more on this below).
Dust container and volume
Opening the upper door reveals a matte black dust container that matches the rest of the body. And behind it is a washable HEPA filter.
One of the features I love about the V3 dust container is this layer of material that covers the filter. It is dense enough to prevent dust bunny from sticking to the filter, which is a problem with Roborock products.
This feature is a nice addition to make getting rid of dirt less messy.
The V3 can hold up to 0.55 liters of dry dirt. It also has a door so emptying it won’t be a problem.
2 in 1 water tank/dust box
In addition to the dustbin, you will also get a 2-in-1 bowl that combines a dust container and a water tank. Viomi doesn’t specify how much water it can hold, but it’s not much.
The difference between a 2-in-1 dustbin and a regular dustbin is in the capacity and the way it is emptied.
For a dustbin, it’s as simple as opening the door and then emptying its contents. The 2-in-1 container does not have a door – you will have to pull out the filter and empty it from the back.
550ml water tank
One important difference between Viomi V3 and Roborock S5 Max and S6 MaxV Is this container.
The V3 has a 550ml water tank – larger than the 291ml water tank in the S5 Max.
In theory, a V3 should cover more area with such a large capacity. But it consumes water at a much faster rate than the S5 Max due to the Y mode it uses.
I filled the tank past the halfway point before testing, and it was empty afterwards.
With LIDAR and SLAM, V3 is one of the most efficient mobility robots. Like its Roborock counterpart, the V3 starts off by cleaning up the edges before moving toward the center section in straight lines.
By default, it will only rotate around the area once. You will need to have the Secondary Cleanup feature turned on for it to run twice.
I tested it extensively, and it was very good at navigating around tight spaces under furniture. He did not once hang or hang himself under the legs of the chair.
Not only is it effective, but it’s also gentle because it will slow down its speed, so it doesn’t hit the furniture at full speed. He just pays it.
You can use this inside big homes because of the advanced algorithm and the recharge and resume feature.
I love LIDAR because it is completely accurate in its positioning. There is minimal risk of losing this robot if there is enough space around the charging base, and you arrange all the wires.
Next, we will look at how this robot cleans different types of debris on hard floors and carpets.
First, let’s look at the overall results.
- Total: 72.82%
- Solid ground: 99.4%
- carpet: 79.8%
- Sand on the hard floor: 99.6%
- deep cleaning: 12.5%
One glaring thing you’ll notice is the results of the deep cleaning pulling the overall score down.
It’s something I didn’t expect, especially with the above-average airflow results, but that’s why all these tests were done.
hard floor results
- Quaker Oats: 99%
- coffee: 100%
- Quinoa: 99.2%
- pet litter: 99.4%
The Viomi V3 was nearly perfect on hard floors at 99.4%, and that’s despite no passes (only 2) compared to Roborock products like S6 Pure.
He was able to make clean passes, although the side brush scattered some debris.
I’ve also tested it on a pile of debris – coffee, quinoa, fruit rings, and Cheerios, and it was able to pick up a very high.
sand on hard floor
Another area in which it excels is cleaning sand on hard floors. She was able to catch Average of 99.6% sand in two tests.
If you use the max setting, it picks up pretty much everything in that path.
Hard floor hair wrap test
I also did a hair wrap test where I spread 1 to 1.2 grams of 5 to 7 inch long human hair on hard floors.
The V3 was able to pick up every strand of it, but a good portion of it was just wrapped in brush.
Only that much went inside the dust container.
I don’t recommend using the V3 for brushing long strands of hair because you will have to spend some time cleaning the brush.
My wife recently had my hair cut, and decided to test the V3 on this kind of mess.
Wow, I managed to catch most of them.
Just look at the dust container afterwards.
Brushing short hair strands like this won’t be a problem.
This robot is better than the Roborock E4 and Roomba 690 which I tested recently.
She was able to pick up a large portion of the ground coffee she sprinkled over the edges. One thing that holds the V3 down as with other ring-shaped bots is the lack of access.
Square-fronted robots like Neato D6 and Roomba S9+ This area will be better cleaned.
The results on the mat are a mixed bag. He’s successfully dealt with certain types of debris like quinoa, and is OK with coffee and Quaker oats, but he’s struggled with pet droppings and sand.
Let’s look at the results first.
Low stack results
- Quaker Oats: 84.8%
- coffee: 88.8%
- Quinoa: 98%
- pet litter: 66.6%
V3 did better with quinoa on the carpet, getting 98% of it. It’s not as loud as other premium robot vacuums I’ve tested, but it’s an excellent grade.
However, it suffered the most from pet litter – up only 66.6%.
- Quaker Oats: 81.6%
- coffee: 82.2%
- Quinoa: 96.8%
- pet litter: 39.6%
Scores of V3 on a medium-pile rug across the board are even lower than on a low-pile rug. This indicates the lack of agitation from the basic brush roll.
I’m not sure why. One thing I’ve noticed when cleaning the V3’s carpet is that the rear end slopes slightly upward.
Any misalignment is a big problem with these machines since they don’t have the same power as a more powerful vacuum cleaner as a stick or upright vacuum.
deep cleaning test
I rubbed 100g of sand on a medium pile carpet to see how well the V3 would perform, and it didn’t do well.
As you saw earlier, it’s only up 12.5%
Carpet Rolling Test
Another struggle for the V3 engine is its inability to pick up hair on carpet.
There is hardly any coiled hair on the brush because most of it is still on the surface. Again, she doesn’t have enough excitement to pick up hair on the carpet.
I opened the dust container, hardly any inside.
So I had to use a file Dyson V11 . torque motor To remove all the hair that Viomi V3 could not catch.
Big debris test
Cleaning up big things like Cheerios and Fruit loops won’t be a problem for a V3 engine. It has enough clearance and suction to do the job.
I tested it on both hard floors and carpet, and it was up to the task on both surfaces.
You can see in the clip above that the V3 makes clean passes, especially on hard floors.
Here’s a short clip of Cheerios and Fruit episodes cleaning up V3 on hard floors.
Some of the debris was kicked up by the side brush, but the V3 was able to clean it up on subsequent passes.
I also successfully cleaned large debris on the carpet – not as clean as on hard floors, but acceptable.
If there’s one reason to buy the Viomi V3 – it’s because it wipes well.
This model is the first hybrid vacuum/mop I’ve tested capable of mopping in a back and forth motion similar to the iRobot Braava.
Viomi calls this Y-style because it does so in a Y-shaped pattern, as you’ll see in the clip above.
Moving back and forth provides better irritation, so it cleans stains better. I tested it on red wine stains, and was able to clean it completely.
There was very little leftover (if any), and you don’t need to do anything after that.
However, this pattern takes longer to finish compared to the straight movement of Roborock S5 MaxWater is consumed at a faster rate.
So it will not cover a large area like S5 Max or S6 MaxV.
I filled my water container halfway through, and used it all up during this run.
How long does Viomi V3 run?
According to Viomi, the 4,900mAh battery will last up to 150 minutes — about 50 minutes less than a battery Roborock E430 minutes less than S6 Max V.
With recharge, resume and smart navigation, this robot vacuum will clean larger areas due to its efficiency.
What comes in the box?
You will get these items from the box.
- Viomi V3 Robot Vacuum Cleaner – Dust box already in it.
- 2-in-1 water tank and waste container.
- 550ml water tank.
- Extra washable pillow.
- Two disposable pillows.
- One charging dock with plug.
- User’s Manual.
It also comes with an extra side brush, so you’ll have something to use if the other is worn out.
Replacement filters, brushes, and pads are available on Alibaba. If you plan on getting this, I suggest you buy the bundles as they offer a better value.
Like all robot vacuums, the V3 needs TLC to run at its peak for years.
These are the things you need to do regularly
- Clean the brushes: Check the side brush and main brush roller for any hair or dirt that may be wrapped in them. Too much hair or debris on it will obstruct air flow and potentially shorten its service life.
- filter: Even if the filter is washable, I don’t recommend immersing it in water as it will dissolve the paper element. Use a handheld vacuum cleaner (such as A Dyson V7 player or Roborock H6) A brush is included to clean any dirt inside the folds.
- Sensors: There are different sensors around and under the robot. Use a clean microfiber towel or cotton swab to clean these areas.
- wiping pad: Wash the pads after each use to ensure that contaminants from the previous cycle do not contaminate your floors.
|Battery||4,900 mAh Li-ion|

Where can I buy Viomi V3?
You can buy Viomi V3 from online stores such as GearBest or Aliexpress. I got mine from the latter. Unfortunately, this robot is not available on Amazon.
A cheaper version – Viomi SE is available for a limited time Under $300 (September 21 – October 4) at GearBest. It has similar features to the V3 but with a smaller battery.
Note: I’ll earn a commission if you buy through any of the links above, but at no additional cost to you, so it’s a win-win for both of us!
Does Viomi V3 offer excellent value?
The answer will depend on what you need from a robotic vacuum cleaner.
For people who are looking for a robot that can mop and clean hard floors, this robot is an excellent choice.
It cleans hard floors just as well and mops as the iRobot Braava, so you’re basically getting two robots for the price of one.
There are some issues with the lack of accuracy, but they are minor compared to the benefits you will get from it.
I will say it is better than the S5 Max when it comes to scanning due to the back and forth motion.
However, they are not good on carpets. Don’t buy this if you have a lot of carpeting or you want it to clean up existing dirt.
Verdict: A great choice for mopping and cleaning hard floors
I am impressed with how the Viomi V3 wipers are. If there is any reason to buy this – the scanning feature alone makes this bot worth considering.
All along, I’ve been hoping that the manufacturer will create a robot that can make back and forth motions, and Viomi does that pretty well.
Consider this robot if you are looking for a standalone assistant that can efficiently mop and vacuum hard floors.
5 reasons to buy Viomi V3
- Excellent at scanning: This is one of the best robots I’ve tested for mopping floors. It will do an excellent job of removing stains on surfaces such as tiles.
- Intelligent navigation: V3 combines LIDAR and SLAM to map and track its location. move around like Neato Botvac and Roborock, but it’s not exhaustive.
- Recharge and resume: If the battery is low and the robot has not completed its task, it will recharge and then resume the last time it was cleaned.
- Great on hard floors: It cleans hard floors efficiently, picking up most debris in the front driveway.
- Feature rich application: Viomi app provides users with many options when it comes to scanning and scheduling.
Excellent choice for cleaning and mopping hard floors
- Mobility – 95%
- deep cleaning – 12.5%
- Surface cleaning – 92.93%
- Quality – 94%
- Design – 95%
- Values - 95%
- TOTALE AVERAGE: 81%
The Viomi V3 is one of the best vacuum and mop combos I’ve tested. In addition to the electronic water tank, it uses a back and forth motion to wipe surfaces making it extremely effective at removing stains. It also scores highly for vacuuming hard floors. Unfortunately, the carpet was not cleaned well. It struggles to catch the sand in medium pile carpets. It’s something to consider for people who are looking for a standalone cleaner to clean any hard surface in their home.
