PROS of the Waterpik Ultra vs Aquarius

Affordability: With the WP 100 the features might be a bit more fundamental compared to the WP 660 however for the shopper on the small budget, this little concession will be very well worth it.

Pacer and time (WP 660): The timer & pacer is actually a function which is now prevalent to higher end electric toothbrushes though it’s less common to waterpiks. The aim is usually to make sure you’re able to effectively and evenly eliminate all of the bacteria every single time you work with your waterpik.

Flossing Settings: The incorporation of ten settings for pressure on a waterpik is actually useful to make certain that you get many options on the kind of pressure you need to tackle your specific problems.

Effectiveness: All the two models have been scientifically proven to be quite effective in removing plaque from under your gums and in between teeth.

Flosser Heads: The more attachments featured with both choices are fantastic for a number of reasons. The much more head attachments that the program comes with the fewer you are going to need to purchase down the road.

2 Modes of Use: The WP 660 offers 2 modes of use that are actually going to improve your experience whenever you using the massage mode which alternates water pressure for a good relaxing feel. Admittedly most users probably will not use the massage mode quite frequently, though it’ll surely be good to have whenever you do require it.


  • 120V Only: All of the countertop by waterpiks are actually compatible with 120VAC/60Hz power outlets, they’re for use mainly in North America. It’s among probably the biggest drawbacks for those likely customers living in some other places.
  • Price (WP 660): the cost of the WP 660 is not in and in case itself a problem. There are really a number of water flossers available that are the exact same price and even more costly compared to this particular feature. The issue actually stems from the facts that the restricted differences between these choices doesn’t always have to correlate with a substantial hike in cost.


On the one hand, the Ultra is actually a bit more basic. You are not getting a great deal of whistles and bells with this choice but ultimately it is still going provide you with the exact same results that you look for in a decent water flosser. The 660 is actually a somewhat premium alternative which will come both with more features and a reasonably larger price tag. If you’re prepared to spend a bit more for style and customization features, then this’s also a good alternative. Another good choice would be an electric toothbrush water flosser combo.

I’d also personally choose WP 660 as you will find discounts in shops from time to time like during Black Friday and Cyber Monday sales. It has the timer feature which allows you to find out when you’ve used the water flosser for adequate length of time, maximizing the advantages of water flosser.
