You're looking for a silent washing machine, so you're not bothered by noise. A washing machine is silent if it has a maximum noise level of 71dB during spinning. You can place a silent washing machine near your living room or bedroom for example. This way, you can also do your laundry when you're working from home or sleeping. Want an extra silent washing machine? The noise level has to be 69dB or less. This is useful if you're in a meeting or studying at home, or have small children.
