It is supposed to have three operating speeds, but in reality, nothing changes with the speed switch. Average performance overall.

Very beautiful, not particularly noisy. Sucks satisfactorily but it leaks. We have also removed the connection to have better performance but it still leaks. Update: We brought a technician from Samsung and he told us that it works correctly and all the new feeders leak... it's a shame because the previous one of 50 euros and 20 years was perfect

For better performance, remove the component that goes before the spiral tube. The manufacturer has it to prevent external air from entering the space, but it significantly reduces the performance of the extractor, so it is not necessary. Remove it for better air absorption performance.

The vacuum cleaner has a problem from the first moment. It doesn't suck at all. Samsung doesn't replace it. I still owe it. Stay away from it. Water everywhere and they tell me it's liquid poetry. It's like you don't have a vacuum cleaner.
