5 Reasons the Dreame H40 Is Quieter Than the s40 Pro

The Dreame H40 runs at around 55 dB, while the s40 Pro operates at 62 dB. That 7 dB difference is significant for everyday use.

A 7 dB reduction means the H40 is about half as loud to human ears. This makes it far less disruptive in quiet environments.

If noise is a concern, the H40 is the better pick. It won’t disturb conversations, TV, or light sleep as much as the s40 Pro.

The H40’s lower noise level doesn’t compromise cleaning performance. You get effective suction without the extra racket.

For shared living spaces or homes with noise-sensitive people, the H40’s quieter operation is a clear advantage over the s40 Pro.
