Good device but the fan seems to be installed crooked resulting in a lot of vibrations when it spins, thus making more noise.
I bought this one because it could connect to the app; if I had known how poorly made the app is, I would never have bought it. You can't create automation scenarios even though it is listed as a feature, and the graphs are impossible to read. Also, the automatic mode is not automatic; it just runs continuously without taking humidity and temperature into account.
On the positive side, I can say that as a dehumidifier it really works excellently except for the noise due to the poor placement of the fan.
**It does not connect to Google Home, Assistant & Alexa, which is a shame for the money it costs.**

Quality construction, reduces humidity to acceptable levels but cannot be considered silent. You can't sleep with it in the bedroom. I have it outside and it still bothers me but I tolerate it because it helps a lot.
Guys, a very good choice for small spaces but also for large ones. I am very satisfied with how it absorbs moisture and with the drying of clothes. Also, with the program it has for air, it effectively removes odors, both from spaces and from clothes, for example, jackets that might smell a bit like smoke from going out do a decent job. You can operate it from your mobile phone with a very easy app, the only downside is that you have to switch your router's power from 5GHz to 2.4 if you want to use it from the app. Value for money at 200, which I bought with my eyes closed
Satisfied. The instructions are a bit lacking. But I contacted support, and a lady who answered me couldn't help with one of my questions, and she took my phone number and said she would update me tomorrow. I thought she wouldn't call me, to be honest. The next day she called me and explained everything in detail. I have no words. And the product is just fine. Of course, it's the first time I've bought a dehumidifier, but everything is good
No dehumidifier at this price is silent. Also, the Wi-Fi function exists when supported by the router or the corresponding transmission technology (older). Nevertheless, it does what it promises but not miracles!
I didn't have any previous experience with a dehumidifier, but for me, I think it's very good.
1) The water tank, which is 6 liters, is extremely convenient. On the first day of operation, it started at 88% humidity and reached about 50% in 5 hours, emptying the water tank twice.
2) In the clothes drying mode, the clothes are completely dry in 7-8 hours.
3) The connection to the wifi is easy.
4) It's not very noisy; it's a fan, so it can't be completely silent.
In summary, in the last few days that we turned on the heater, it runs for 5-10 minutes daily
The noise is fine, but the fan inside is crooked; however, it's still good and the container is large, easily lasts 24 hours
- It reduces humidity inside the house to normal levels
- It helps a lot with drying clothes (it also has a drying function for clothes)
- It has a 5-year warranty
- The 6.5-liter tank is very helpful because you don't have to empty it constantly.
The only downside is that it makes a bit of noise, but this is the first dehumidifier I’ve bought, so I don’t have a comparison with others. Other than that, I recommend it; it has helped us a lot in the house!
It does its job very well, it immediately reduces humidity, of course in a house with average humidity because many write that it doesn't work and if you live in a basement or a house with constant humidity you should change houses not get a dehumidifier. The tank is very good as well as the WiFi function. The noise is good for us because it helps us sleep better.
The Rohnson dehumidifier with ionizer and Wi-Fi is an excellent choice for combating humidity at home. With a capacity of 20lt, it manages to keep the space dry even in high humidity conditions. The ionizer provides additional air purification, which is very useful for me since I have allergies. The Wi-Fi function allows me to control it remotely via an app, which makes my daily life much easier. It is silent and has a modern design that fits well in the space. I am absolutely satisfied!
Good dehumidifier, noisy for bedrooms at night. It also emits cold air. Less noisy on the lower setting.
When the air purification is activated, the dehumidification stops. The Ionizer and UV lamp are always activated as described in the instructions, but they are invisible to us!!
Huge 6-liter water tank takes at least 2 days to fill. The second largest water tank after the combo inventor. Great convenience and the tank is also high-quality and ergonomic with a handle. Heavy for elderly individuals when it is full.
Elegant, high-quality, rotating.
Rohnson r-9920 genius Wi-Fi dehumidifier application. In the cycle, when the application is open, the humidity percentage for adjustment does not appear, instead, two dashes - - appear.
Also, I do not see a setting for UV-C in the application, only an 'air clean' button which, when activated, deactivates the dehumidification!!!! The application has deficiencies in its functionality. Is there any problem?
Nice construction, only if it doesn't fit well, it creaks. The noise is quite annoying. It reminds me of a 90s air conditioner. It's difficult to sleep with the device on.
Good morning,
I bought the Rohnson 9920 yesterday because of its 320 watts and large water tank. Yesterday, when I turned it on at 17:00 and checked the power consumption meter, I saw that it does not exceed 230 watts. I should note that the meter is highly accurate and has been tested with many devices.
Nevertheless, from yesterday at 17:00 until now at 05:48, it has managed to reduce the humidity in a 40 sqm space by only 8 degrees, from 66 to 58, with a room temperature of 19 degrees. I spoke with the store where I purchased it as well as with the manufacturer (they haven't responded yet), and the company that supplied it told me to come and give me another one on Monday in case I received a faulty one. After the replacement, I will measure the power consumption again, and if it still shows 230 watts instead of the advertised 320 watts, then it's not worth it. For the same price, the inventor eva ii pro is available, which I have and it is excellent, just with a smaller tank.
It also mentions a UV lamp, but even in complete darkness, I couldn't see anything shining inside, except for the green indicator in the front that shows the humidity level.

The big plus is the mobile application and the large water tank. Buy the Hepa filter together and it's worth every euro.
On the negative side, the noise, but we can't have it all.
It is efficient, has good construction, and its container is very large. However, it is not quiet in any case. I operate it daily during hours when I am not at home.
Not that it's necessary, but it cannot connect to wifi since it exclusively requires 2.4 GHz. It's ancient, basically. Other than that, it works very well.
It seems to do the job and the first impressions are very good. Just be aware that it is not as quiet as it claims to be, it makes a sound like a refrigerator (compressor) + fan. You definitely can't sleep next to it, but if it's in another room and you're not very sensitive to sounds, it's okay.
By far the best dehumidifier. Firstly, it has the largest tank available, 6 liters, and believe me, this makes a difference. Secondly, it is the most complete, with an ionizer, UV sterilization, and WiFi. The last one is not a joke, you can program it to work during off-peak hours and solve the issue of usage cost. Thirdly, it has a 5-year warranty from the company, which was impeccable when I needed it. For me, the second of the two identical machines I have was a replacement for an older model that broke down after 3 years of daily use due to the power company... It's not silent, but no one is in full operation. However, it doesn't bother your ears either...
I have had the dehumidifier in my possession since December, and I am very satisfied with its use. It lowers the humidity very quickly, and with the use of Wi-Fi, it becomes a breeze. The large tank has saved me, I truly forget to empty it.
Very quiet. Solid construction immediately removed the humidity. Although the meter reads 69 and the air conditioner read 80. I will come back with a newer evaluation
The worst electrical device I have ever purchased. It cannot remove humidity. Another type of Rohnson dehumidifier, much smaller in size, immediately removes humidity in the same space. It is noisy and shakes. Failed purchase. Stay away.
To dry the clothes, it should be in a closed room, not in a more open space. Generally, though, for its price, it has done what we expected. It is NOT quiet
Perhaps the best purchase I have made for my home. The house is about 80 square meters and is located in front of the sea.
I have been using the dehumidifier for 10 days now. The humidity before I bought it was at 75%. On the first day, it worked continuously for about 9 hours with the fan speed set to high until it lowered the humidity to the 50% that I had set. Now it easily keeps the humidity below 50% and operates for a total of 3-4 hours throughout the day with the fan speed set to low.
It is not very quiet, especially when it is running at full speed, but I consider it reasonable for a device that blows air. Personally, it doesn't bother me.
The water tank is quite large and you actually forget to empty it.
The connection to Wi-Fi is very easy and works flawlessly. The app is not anything extraordinary, but it has several functions such as a timer and presets for automatic dehumidification.
I have the dehumidifier in the kitchen and there is a slight difference of 3-4% with the living room and bedrooms, but I consider it completely normal.
The build quality is excellent, sturdy construction without any creaking in the plastic parts.
The activated carbon filter is not included, you have to buy it separately and it costs 20 euros.
The ionizer eliminates various odors and freshens the atmosphere.
An exceptional device, I am really very satisfied.
I mainly got it for the container, which is huge. My apartment is 55 square meters, and I needed something bigger and more efficient than the previous one, due to the dryer, cooking, and bathroom. Overall, it is good. Some observations I have to make are the following. Its hygrometer does not work well. It shows quite large differences compared to another one I have at a distance of 4 meters, like 10% difference sometimes. As a result, I have set it to 55% desired humidity, and it has gone up to 67% in the room and has not started. This annoys me quite a bit. Its app, ok, you can control it remotely, but it does not show you the actual humidity of the room according to the above. Just a simple app. I would like it to have Alexa skill so that I can create a scenario for it to trigger with the WiFi hygrometer I have, which works correctly but unfortunately it does not have. It is a quite quality construction though. It is not a bad purchase. Just for the huge container alone, I would prefer it over others.
In no case is it silent, as stated in the description.
The construction is mediocre, (it is evident in the quality of its plastics).
We bought it for its silence, and it is not.
Also, it slightly trembles during its operation.
In the positives:
- Large bin! A big enough bin to forget to empty it.
- Removes moisture where it should.
- Wheels for easy transportation within the house.
In the negatives:
- You can't exactly call it silent, but not terribly noisy either.
I did not try the ionizer.
Very good construction. One thing I will tell you....... my husband accidentally dropped it on it at night (he didn't see it), the machine took a strong hit (my heart skipped a beat at night) but it continues to work flawlessly.
As for dehumidification, we are next to the sea, it reduces it to 55%. I have it on almost all day.
I put it in the bathroom, every time I take a bath and within an hour it doesn't leave a single drop.
At night, you can't have it in the room, you will wake up with a headache. Basically, no matter what you buy, it will make the same noise, since it operates with a fan.
I don't know what to expect from the dehumidifier as I didn't have any other experience. It definitely does the job for which it was purchased, although it doesn't lower the humidity particularly quickly (55 sq.m.). It needs to work all day to reach 55%.
It makes noise within reasonable limits, sometimes it bothers, other times not so much. It's difficult to sleep with the dehumidifier on, though. The ionizer should do something as well, but I didn't see any significant difference.
The container is huge, I empty it twice a week, maybe even less frequently, and the mobile app is amazing. Overall, it's a decent purchase.
I have had it for a year, without any previous experience with another dehumidifier, I am completely satisfied! Last year I moved and the house had a lot of humidity, with the walls dripping, but with the dehumidifier we calmed down!
Perfect construction! Knock on wood, I don't want to jinx it! The humidity levels here in Lemnos, specifically in Kaspaka, are extremely high. So far, it seems to be doing its job and more. Easy to connect to Wi-Fi, and even my grandma can set it up...
