This parameter determines how much moisture will remain in the clothes after washing. For different models, this value ranges from 800 to 1800 rpm, but not always more means better. Excessive spinning will damage the fabrics and the clothes will be dry enough at a speed of 1000-1200 rpm.
If you have a small apartment, small children or the elderly, whose sleep is fragile, it is better to choose a model with a characteristic of 70 dB - this level is considered the most comfortable for perception.
