We named the Waterpik Aquarius Water Flosser the best water flosser overall thanks to its reliable flossing action, versatile design and great value. It carries the ADA seal of approval (not all flossers do), comes with a three-year warranty and has been our top pick for years. This flosser includes seven tips—tied for the most, of the water flossers we tested—so you can customize how you floss.

The Waterpik Aquarius is one of the most popular models on the market and it also earned the ADA’s Seal of Acceptance. You can remove the water flosser’s 22-ounce reservoir from its base, making filling and cleaning in the dishwasher convenient. The device uses pressure and pulsations to lift plaque off teeth, and you can choose a pressure setting using the built-in dial.

The Aquarius model is ideal for anyone who wants a deep, customizable clean with more control over the pressure settings. It feels gentle on the gums and that massage mode really adds a nice touch. It's easy to use and the timer ensures that you don't miss any part of the process. On the other hand, the Cordless Express is perfect for quick onthe-go cleanups.

The Waterpik Aquarius Water Flosser is one of those bathroom upgrades you do not know you need until a dentist explains to you that using just a string floss will never be sufficient. It shoots a small, pulsed jet of water in between your teeth and around the gum line where no toothbrush or floss has reached before.

Despite its compact size (great for keeping your countertops clear and for travel), this water flosser, from arguably the most respected name in the category, is perfect for a family of four. It comes with four tips, plus it is equipped with three pressure settings ranging from 45 to 75 PSI.

My mouth feels sparkling clean. Like, I just left the dentist chair. The pressure is strong, but not painful, and you can adjust it with 10 different settings. I keep mine around level four or five. It's plenty for my sensitive gums, but I know others in my family use it on higher settings with no issues.

As soon as I unboxed the Waterpik Aquarius, the first thing that struck me was how thoughtfully the unit is laid out. The base houses a 10 pressure setting dial that lets you glide from a gentle rinse for sensitive gums up to a robust stream that feels like a miniature dental drill. Perfect for dislodging stubborn food particles.
