No,
I have a Dyson and never heard of it before just now, but I googled the product.
However,
The Best Silent Vacuums For 2019 - Home Vacuum Zone lists that brand as having 70dB, which isn't the quietest of things. And considering that the product isn't pushing 400-odd pounds through the water at speed, isn't the best comparison to a Jet Ski motor in loudness. I used it in my original example only to illustrate that a non-gasoline appliance still can be quite noisy, despite being pure electric.
An electric jet ski would be quieter, certainly, but it will not be
Tesla quiet which is the original point.
