Quietness is a quality easy to overlook until you find yourself reluctant to use it for fear of waking up everyone in your household/apartment building/surrounding neighborhood.

I used one a million years ago when I was a teenager and I hated it because it legit sounded like a lawnmower. Are they still so insanely loud?

The quietest one I’ve found so far is Phillips Sonicare—it’s not much louder than an open tap or running shower.

I do like Waterpick, because I had a good experience with their customer service. (I messed up the travel sized one by letting the batteries leak out in it, tried to purchase a replacement battery door and they sent me a brand new one.)

I have a portable and a regular unit.

When my Waterpik broke after years of use I was happily surprised to learn they still had replacement parts available.

Waterpik is a great company.

I have a few of their products and one had an issue, I called them, immediately got a human, and had my waterpik replaced in 3 days.

It was an absolutely refreshing customer service experience, no chat bots, no phone bots, not complicated phone menus, just a ring and a hello how can we help you.

Love Waterpik.

Get the wireless one. It’s worth it.

The plug-in waterpik ones are worth it in my opinion. Finally got into a routine of flossing after buying one.

A few more things to think about if you plan on buying a cordless unit and using it frequently though. If it takes AA batteries, it will eat through them like nothing else and the battery compartments tend to get gross and slimy, worse if the AA batteries leak. Also avoid the cheap off-brand units that take just 2 AA batteries. In my experience, those don’t produce nearly enough water pressure.

Only major gripe with waterpik’s cordless units are that their water tanks are a hassle to clean and keep clean due to the narrow openings and nooks and crannies. Later got one from Guru Nanda where the motor sits atop a wide-mouth reservoir, which is much easier to clean, or even just keep separate from the motor after use so everything can dry out.
