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.
Pros
- Modern look
- 10 pressure settings
- Convenient On/Off button on the handle
- Massage mode
- 7 flossing tips
- Large water tank (650ml)

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.

I had the Aquarius WP660 for over a year when the reservoir started leaking. When I contacted Waterpik about purchasing a replacement reservoir they informed me that it was leaking because I left water in the reservoir between daily usage. I find that ridiculous, why design a large capacity reservoir if it has to be emptied every day?
Also- I have never been able to turn off the water with the button on the handle. I turn it off and on with the button on the main unit. I give this product 3 stars and I would not recommend spending the money.
I had a problem with an older waterpik’s hose. The response I got from the company was a significant brush off. Their main response was that no parts are made for this model and it can’t be opened to fix the hose. There are also numerous instructions on UTube to replace and fix all
waterpiks.
Well, it certainly can be gently pried open and new floss hoses are available on many websites. You can also use medical tubing of tubing from an aquarium store. I later found out that Waterpik was purchased by another company and is most concerned with their first annual net profits.
This is one of the reasons I keep stopping myself from ordering this product. I am searching for a decent water/air flossier but there are ton of reviews on Amazon complaining that this unit leaks.
I have purchased 2 Water Pik Model 600C about 4-5 years ago and both have developed leaks, bu no one can tell me where the leaks are. Water Pic was absolutely no help! I’ve hesitated to purchase a replacement hose/hand;e kit but concerned that the lead was coming from somewhere else. I’ve replaced the small washer on the end of the hose and tightened all the screws on the base of the unit, but no success. It still leaks. Any suggestions?
I was considering purchasing this flosser but after reading these review I am going to pass. Sounds like the company does not stand behind their product and let’s face it, we all hate lousy customer service.
You should still buy it…it is amazing. Read the 1000’s of good reviews online and the one above over a couple poor one’s. Love mine with all the settings it has and how it simply does an amazing job.
My wife just purchased one last year and last week it broke. It lasted just over a year. The pump stopped pumping. I could hear it try to come on when I turn it on but the motor does not run.
This must be the sixth or seventh unit (different models but all Waterpiks) that she has had in eleven years. I tried looking for other manufacturers but none has good reviews.
Does anyone know of any water floss that lasts more than a year or two? I am willing to pay a premium as long as it is quality built.
It is supposed to have a 36 month warranty.
Appreciate the reviews. However i have searched far and wide to see if someone came up with a quiet or ‘quieter’ device…?
These units are LOUD!… and coming home from a long day’s work court case and cleaning your teeth before bed wakes you up as well as the rest of your house…
I thought my vacuum was noisey, this is ridiculous, ear pollution & the water hole in bottom of the reservoir is leaking after only one year. The little black plug needs to be replaced I think, but where do you find parts for this thing? Not happy consumer
