We renovated our kitchen and am so disappointed with this rangehood. I wish that I had read the reviews. The buttons are so loud they give me a headache but unfortunately am stuck with it.

Faulty button and lights after under 1 yr of using. Called up customer service, very poor service, slow to arrange for someone to come out and assess. After assessing said they needed to order parts. They put the order in apparently 2 days later and then 4 weeks later still haven't received the parcel apparently so not sure if it was even sent. In email correspondence, no apologies ever given for the ridiculous amount of time it has taken to fix one small issue. Have been trying to cook without a functional rangehood for over 6 weeks now. Very frustrating to say the least, customer service not helpful. Will not buy from schweigen again.

Our HN-9UM undercount extractor has never extracted effectively! It makes a lot of noise, however most of the cooking smoke, steam and fumes end up all through our living room!
Sadly need to replace with something that actually works!
Do not buy!

bought a schweigen Um 1170-9s under mount for a kitchen reno supposed to be tops . Had it installed by a schweigen rep. ran for about 4 years then started doing its own thing. turns on whenever ,sometimes immediately after turn off ,sometimes hours later . Replaced both switch panel and control board on recommendation of service dept . good for 5 months ,now doing the same again . not happy it would appear the control board has in built problems .Would appreciate schweigen having a solution as I see this complaint on other reviews .

We have had our unit for three years now. One of the switches doesn’t work and the rangehood doesn’t cope with rapidly boiling water. We get water dripping down off filters and trim. We only use it on full power as it is useless otherwise. A very expensive appliance that does not live up to reputation.

Very disapointed in the 900 under cuphard model when first turned on just about shook the whole house.took 4weeks for a new unit to be fitted the unit is noisy not quite like advertised. My old 10 year old unit upstairs is much quieter. Please dont use false advertising in saying it is a quite unit.
I will repost after i have used it for a while and see if it improves .

Bought earlier this year and installed in February. Pretty sure this blows as opposed to sucks.
Called the customer service team who without waiting for me to finish explaining the problem blamed the installer - appears to be a pattern here. Not impressed at all and will not recommend.

As most quite great for our requirements Fantastic I am so surprised that it turns its self on when it wants to, GREAT you might add but fails to turn its self off. No body told me it worked through wifi lol lol, Replace board etc the serviceman didn't even reach our street corner when away it went again. Told don't worry if it gets to hot the circuit breaker will kick in. I know what I would like too kick!!!! This is only max 18 months old bought Harvey Normans expensive best you can buy lol lol,

Drips oil continuously on hot plate while cooking, was recommended but I won’t be doing the same. Purchased from our usual supplier to whom we have given a lot of business

Bought NAUM9 for my new kitchen as Retravision promised that it’s the best value for money brand and performance wise. Upon installation, the LED lights are flickering almost dying and the motor is extremely loud, which is almost similar to lawn mower. I have kids and I cant even here them in the living area which is adjacent to my kitchen. My dream kitchen turned into nightmare all because of this rangehood. Called customer service and still no response. Very bad product.

Pad almost $1000 for this when we upgraded our kitchen. We bought it because we were told it was ‘whisper quiet’, it isn’t. It only had one fan setting as well and we think it’s no better than the no name brand one we replaced. The lights are dim as well and the suction is poor. Wouldn’t buy again, that’s for sure.

For the price it is an excellent range hood it’s super noisy but for the amount of times you put it on full speed it’s bearable the suction is awesome you can see all the fat deposited on the vents which go straight into the dishwasher and presto it’s shiny clean. The only issue was just before it was a year old one of the fan switches didn’t work and the light globe blew out. Luckily all covered by warranty. If you are looking for a superb rangehood on a budget this one is a definite.

We have the under mount version with 1600 external motor. Excellent extraction even on medium speed and very quiet. It's not silent, but the sound is barely noticeable. As others have commented, on the low speeds you'll forget it's even running as you can't hear it. The outside unit is quite loud on the highest speed, so make sure you position that somewhere that won't disturb your neighbours.
