  • The positives are obvious: it does a good job, it doesn't collect dust very quickly, its bin is huge, and the noise it makes is tolerable. But guys, if it decides not to connect to WiFi, it won't connect until you move house. I have bought it twice. Once for myself four years ago and once last year as a gift. Honestly, I had to move for it to decide to connect to WiFi again.

  • One of the good choices in its category, I was satisfied. The only thing I would have liked is a remote control; this one is operated from the app on your phone.

  • Overall, it does the job... Its ionizer is very good, it makes a lot of noise especially at night, it has a child lock, the clothes drying is satisfactory, the night mode is decent but still noisy, be very careful with the indicators, on the first day I got confused and set it to continuous flow in a renovated house and the next day when I returned the room was flooded, check the manual a bit *

    Its app works quite well and so does the WiFi!

    P.S. For smart home fans, it's not that great because it uses a type of chip that doesn't show up in Google Home or Alexa, it works with its own app! So you can't create routines and voice commands, it can also connect to the Smart Life app which somewhat saves the situation but still wasn't convenient, in the next few days I'll try connecting with HA and I'll report back!

    Update 01/02/2026: HA recognizes it only as an ionizer and not as a dehumidifier due to the chip

  • An amazing machine that solved my humidity problems. The atmosphere changed from the very first moment. We do not smoke and the atmosphere was always pleasant. With this machine, it became lighter and by removing the humidity, the rooms became warmer. The instruction manual is incomplete. The only issue I have noticed is that the instructions for the Wi-Fi are not easy and I still haven't managed to familiarize myself with it.

    Totally useless. After the two years of warranty, it developed a leak in the circuit and a problem with the motor. It's simply for throwing away or only for 2 years. The manufacturer knows.

    Fantastic dehumidifier! It does what it says and with quite low energy consumption. I extract two liters of water a day. It is definitely not silent. If it were, it wouldn't do its job well. The mobile app is excellent. VFM

    Noisy, takes a long time to reduce humidity and almost never reaches the target, e.g. with 70% humidity, it lowers it to 65% after about an hour, while the target is 55%. I tried with various settings, but the result is the same.

    Attention, it does not have fins to direct the air. The application on the mobile, if the device loses power, it loses memory with any setting. THE IONIZER AND THE DEHUMIDIFIER DO NOT WORK SIMULTANEOUSLY

    It is definitely not silent, but on the low setting (it only has two) it is really bearable. The ionizer eliminates odors perfectly. Also, combined with heating, it makes the room warmer for a longer duration. The tank is very large and sufficient for 24 hours. Finally, I didn't install the app because the reviews were not positive.

    To clean from odors, which was one of the main reasons it was purchased and for which an extra filter costing €20 was also needed, it definitely doesn't do that much work. The filter is very small in size. Models with larger filters work better because more air passes through them faster for cleaning. It reduces humidity but is very loud. You can't call it silent at all. For no reason should you sleep with this in the room, and yes, there are definitely quieter ones for the same price. Among those I've seen in friends' homes, etc., it is easily the loudest. On the positive side, the very large tank collects water so you don't have to empty it every few minutes.

    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. It's hard to sleep with it in the bedroom. I have it outside and it still slightly 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

    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

    - 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?

So you can't create routines and voice commands, it can also connect to the Smart Life app which somewhat saves the situation but still wasn't convenient, in the next few days I'll try connecting with HA and I'll report back!

    Update 01/02/2026: HA recognizes it only as an ionizer and not as a dehumidifier due to the chip

  • An amazing machine that solved my humidity problems. The atmosphere changed from the very first moment. We do not smoke and the atmosphere was always pleasant. With this machine, it became lighter and by removing the humidity, the rooms became warmer. The instruction manual is incomplete. The only issue I have noticed is that the instructions for the Wi-Fi are not easy and I still haven't managed to familiarize myself with it.

    Totally useless. After the two years of warranty, it developed a leak in the circuit and a problem with the motor. It's simply for throwing away or only for 2 years. The manufacturer knows.

    Fantastic dehumidifier! It does what it says and with quite low energy consumption. I extract two liters of water a day. It is definitely not silent. If it were, it wouldn't do its job well. The mobile app is excellent. VFM

    Noisy, takes a long time to reduce humidity and almost never reaches the target, e.g. with 70% humidity, it lowers it to 65% after about an hour, while the target is 55%. I tried with various settings, but the result is the same.

    Attention, it does not have fins to direct the air. The application on the mobile, if the device loses power, it loses memory with any setting. THE IONIZER AND THE DEHUMIDIFIER DO NOT WORK SIMULTANEOUSLY

    I feel that sometimes it takes a little longer, but to be fair, it's a large space with kitchen, living room, and dining area together; also, the app really helped me incredibly

    It is definitely not silent, but on the low setting (it only has two) it is really bearable. The ionizer eliminates odors perfectly. Also, combined with heating, it makes the room warmer for a longer duration. The tank is very large and sufficient for 24 hours. Finally, I didn't install the app because the reviews were not positive.

    To clean from odors, which was one of the main reasons it was purchased and for which an extra filter costing €20 was also needed, it definitely doesn't do that much work. The filter is very small in size. Models with larger filters work better because more air passes through them faster for cleaning. It reduces humidity but is very loud. You can't call it silent at all. For no reason should you sleep with this in the room, and yes, there are definitely quieter ones for the same price. Among those I've seen in friends' homes, etc., it is easily the loudest. On the positive side, the very large tank collects water so you don't have to empty it every few minutes.

    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. It's hard to sleep with it in the bedroom. I have it outside and it still slightly 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

    - 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.

  • The positives are obvious: it does a good job, it doesn't collect dust very quickly, its bin is huge, and the noise it makes is tolerable. But guys, if it decides not to connect to WiFi, it won't connect until you move house. I have bought it twice. Once for myself four years ago and once last year as a gift. Honestly, I had to move for it to decide to connect to WiFi again.

  • Overall, it does the job... Its ionizer is very good, it makes a lot of noise especially at night, it has a child lock, the clothes drying is satisfactory, the night mode is decent but still noisy, be very careful with the indicators, on the first day I got confused and set it to continuous flow in a renovated house and the next day when I returned the room was flooded, check the manual a bit *

    Its app works quite well and so does the WiFi!

    P.S. For smart home fans, it's not that great because it uses a type of chip that doesn't show up in Google Home or Alexa, it works with its own app! So you can't create routines and voice commands, it can also connect to the Smart Life app which somewhat saves the situation but still wasn't convenient, in the next few days I'll try connecting with HA and I'll report back!
