The Dreame L10s Ultra at 62 dB is the quietest vac I've tested

The Dreame L10s Ultra runs at about 62 dB, which is noticeably quieter than most robot vacuums — quiet enough that you can run it during a meeting or while watching TV without cranking up the volume. Most robot vacs in this class hum along in the high 60s to low 70s, and that difference matters if your home is open-plan or if you run the vacuum overnight. The Dreame isn’t silent, but it’s the least intrusive vacuum I’ve tested for noise.
