Less robust than previous models.



  • - 1 Minute cleaning timer with 30 second quad timer.
  • - Handle on/off control.
  • - Gum massage mode.
  • - Led Information Panel.

Pros: This oral irrigation unit performs very well. The on/off switch on the handle is a nice feature that allows the cleaning tip to be positioned in the mouth before turning on the water. Great selection of cleaning tips.

Cons: The WP-660 feels less substantial than earlier models, the plastic is thinner and the body is not as robust as other flossers.

Conclusion: The WP-660 Aquarius is a nice unit that performs very well. It does feel rather light weight compared to the older Waterpik Ultra WP-100 but the operation and performance is still of the high quality you would expect from a Waterpik device. The recommended retail price is more than the WP-100 and it is debatable whether it is worth the extra money but if you shop around they can usually be purchased at a very reasonable price.

I bought this on the advise of my dentist to help with chronic gum problems. This is the first time I have used a power flosser and I am delighted with the results. I put a small amount of mouthwash in with the water for extra benefits. My mouth feels super clean afterwards.
