Waterpik Aquarius Water Flosser
Waterpik Aquarius is by far the most popular and sold model on the market. The WP-660 and WP-662 are essentially the same product. The only difference is that the 662 is black in color and the 660 is white.
The two models are also widely known as the Aquarius Professional Water Flosser. A simple search on Google for the models or the Aquarius name would effectively return the same results.

Reviewing the Waterpik Aquarius
Being advertised as the most advanced oral irrigator out there, this Waterpik does come fully equipped to support that statement. To highlight a few:
The Waterpik Aquarius comes fully built and ready to use once you open the box.
At first, it appears that a lot of ingenuity and thought process have went into the design of the WP660. The unit is smartly designed, functional and sleek looking. It’s hard to picture my bathroom without it at this point.
But, at a closer look, some of the features are not completely thought trough. For example, for ease of use, the water tank comes with measurements printed on one of its sides. However, it appears to be the wrong side, because you cannot read the measurements unless you pull out the reservoir. It becomes rather inconvenient having to remove the reservoir every time you want to fill it up to a certain point.
One good thing about the water tank is that it is dishwasher safe and friendly. All it takes to clean is one quick cycle.
Another cool thing about the WP660 unit is its hidden flosser tips’ compartment. Not easily noticeable at first. Have a look at the image below.
Once you remove the reservoir, you can store up to two flosser tips there.
Unfortunately, the way this compartment is designed, it can only accommodate the classic tips. Trying to fit in tips with bristles simply does not work. There is not enough space with the current design.
Forcing the bristles in, would cause them to bend. Continuously doing that, will cause them to stay bent; and therefore, ruin them. In this regard, the tip holder on the Waterpik Ultra model was more convenient and better thought through.
The controls on the Aquarius water flosser are simple and straight forward to use. There are 3 settings located on the left hand side of the model:
- Power button – turns the water flosser on. The ON/OFF button on the handle will not do this.
- Mode Selector – switches between flossing mode and massage mode.
- Pressure setting – adjusts the water pressure from 1 to 10.
In order to determine the PSI that each number represents, simply ad a zero to the back. So, 1 is equal to 10 PSI and 10 is equal to 100 PSI. This is not visually verified by the model, but it is available information in the instructions booklet.
Flipping the unit around does not reveal an ocean of new information. There is not much on the bottom, except for the four black rubber feet. They do a good job at preventing the unit from slipping and sliding.
Try lifting the unit, instead of dragging it around your countertop. This will prevent the rubber feet leaving markings on the top.
The top 3 reasons people choose this model is the gum massage, the 30 second pause button on the handle, and of course, the aesthetics. The top reason we recommend are the 10 different pressure settings. This option makes the Aquarius usable by different people with different gum sensitivity.
NOTE: There are some reviews where people describe the ON/OFF button on the handle as being hard to operate. There are several negative reviews in that regards, circulating the internet. It also needs to be noted, however, that some of them are by people who have reported to have arthritis in their fingers. Having said that, it is likely that such people would have difficulties operating all similar oral irrigation devices.
