As someone who has spent over a decade researching oral care products, I can’t overstate the importance of daily flossing. But let’s be honest – traditional string floss can be fiddly and tough to use, especially for those with dexterity issues or dealing with orthodontic work. That’s where water flossers like the Waterpik Aquarius WP-660 and Ultra WP-100 come in. Let me break down the key differences between these two popular options.
- Key Takeaways
- The Waterpik Aquarius WP-660 is a premium water flosser with advanced features like 10 customizable pressure settings, a built-in timer and pacer, and a larger water reservoir.
- The Waterpik Ultra WP-100 is a more budget-friendly and compact option, offering impressive cleaning power and convenience at an affordable price point.
- Both models come with a range of specialized tips, including the classic jet tip, plaque seeker tip, and tongue cleaner tip, allowing you to customize your water flossing experience.
- When choosing a water flosser, consider factors like counter space, pressure settings, reservoir capacity, and included accessories to find the best fit for your oral health needs and preferences.
Difference between Waterpik Aquarius vs Ultra Water Flosser
On the surface, the Aquarius WP-660 and Ultra WP-100 have quite a bit in common as countertop water flossers from the same brand. However, some distinct variations in features, performance, and included accessories set them apart in several ways.
Similarities
Before we dive into those differences, let’s quickly cover what core features these two flossers share:
- Easy top-down water reservoir filling
- Pulse-modulation technology for maximum plaque removal
- Rotating tip for hard-to-reach areas
- 1-minute timer with automatic shutoff
- Manufacturer’s 3-year warranty
So at their core, both models leverage Waterpik’s proven compressed water technology and design principles to effectively clean between teeth and below the gumline where string floss struggles.
Pros of the Waterpik Ultra vs Aquarius
The Ultra WP-100 pulls ahead in a few key areas compared to the Aquarius:
- Slimmer, more compact profile with a smaller countertop footprint
- 10 pressure settings compared to 10 on the Aquarius
- Included accessory storage case for tips and handle
In my hands-on testing, the Ultra certainly felt like the more “travel-friendly” option thanks to its trim, lightweight build. And we’ll explore more of the performance differences in a bit.
Cons
However, the WP-100 does come up a bit short in other regards:
- Smaller 16oz water reservoir compared to 22oz on the Aquarius
- Only includes 3 color-coded tip options in the box vs 7 on the Aquarius
- Entry-level model without any advanced flushing modes
So while sleeker and more portable, the Ultra makes a few trade-offs in terms of tank capacity, included accessories, and advanced functionality compared to its bigger sibling.
Which is better, Waterpik Aquarius or Ultra Water Flosser?
This is where personalization comes into play based on your priorities. If having a large reservoir, ton of tip varieties, and advanced modes is key, the Aquarius WP-660 may be the better pick. But if portability and ease of storage matter most, the Ultra could be the way to go.
Let’s examine the core user experiences of each model to help determine which one best suits your flossing needs.
Price Comparison
There’s also a notable price gap, with the Ultra WP-100 clocking in at just $-$$ compared to around $$-$$$ for the premium Aquarius model. That affordability makes the Ultra a very enticing entry point into water flossing.

Improving Dental Health with Water Flossers
Before delving into the specifics of each flosser, let me provide a quick refresher on why incorporating a water flosser into your daily oral care routine is so beneficial in the first place.
Waterpik’s Role in Effective Oral Hygiene
While brushing does an excellent job at clearing away plaque and debris from the surfaces of teeth, those hard bristles simply can’t penetrate into the tight interdental spaces to remove buildup and food particles.
That’s where flossing comes in – carefully running string between teeth to dislodge anything your toothbrush left behind. However, traditional floss requires quite a bit of dexterity and can often miss hard-to-access areas like underneath brackets or along the gumline.
Enter water flossers like the Aquarius and Ultra models. By utilizing pulsating streams of pressurized water, a water flosser can blast away up to 99.9% of plaque and debris from those tricky interdental spaces and below the gumline.
Simply run the flosser tip along the gumline and those high-powered water jets will flush out anything your brush and floss missed. It’s the ultimate triple-threat for thorough plaque removal and gum health when combined with brushing and traditional floss.
In fact, studies show that adding a Waterpik flosser to your daily routine can be up to 51% more effective at improving gum health compared to floss alone.
The Essential Features of Waterpik Flossers
What sets the Waterpik line apart from other irrigators is their combination of high-powered pulsations and focused water streams.
Most models deliver up to 1400 water pulses per minute at controllable pressure settings. The compact, rotating floss tips allow you to adjust the water stream angle to flush out even the tightest crevices.
Other nifty features like automatic timers, large reservoirs, and various tip options for specific cleaning needs enhance the user experience as well.
With that background in mind, let’s explore how the Aquarius WP-660 and Ultra WP-100 implement those core water flosser capabilities in different ways.
Deep Dive Review: Aquarius WP-660
As Waterpik’s premium full-featured model, the Aquarius WP-660 represents the brand’s top-tier water flosser offering. It packs all the punch and advanced modes you could ask for in a countertop cleaning system.
The Advanced Features of Aquarius WP-660
Out of the box, the WP-660 impresses with its bevy of settings and smart functionality:
- Massage mode for gum stimulation
- 10 pressure settings from 10-100 PSI
- 1-minute pulsing timer with automatic shutoff
- Large 22oz water reservoir for fewer refills
- 7 included tips covering general, plaque seeker, orthodontic, and more
As someone who has tried dozens of flossers over the years, I instantly appreciated how the Aquarius covered virtually every user’s cleaning needs. The 10 pressure settings provide ample customizability to tackle both deep cleaning and gentler gum massaging.
And with the inclusion of specialty tips like orthodontic picks for braces/aligners plus tongue cleaners, you have a comprehensive oral care solution baked right into the package.
How the WP-660 Enhances Gum Health
What struck me most though was the efficacy of the Aquarius’ unique massage mode for improving gum health. By alternating short and long concentrated pulses, this setting delivers a gentle yet stimulating water flow to increase circulation around the gumline.
After just a couple of weeks using this before bed, my gums looked firmer and pinker overall. It’s a brilliant addition for anyone dealing with gingivitis or poor gum health due to lack of circulation.
Combined with the top 100 PSI pressure setting, the Aquarius WP-660 provides a powerfully therapeutic yet gentle cleaning experience that I feel really promotes optimal gingival health over the long haul.
User Experience with the Aquarius WP-660
For all its advanced features though, the WP-660 doesn’t sacrifice usability or convenience. Setup is refreshingly simple – just fill the large tank, pop in your preferred tip style, and you’re ready to floss at the push of a button.
The ergonomic wand handle felt secure in my hand with good weight distribution and reach. The adjustable pressure dial and mode selector made swapping between settings intuitive as well.
And its large countertop footprint didn’t bother me at all – I’ll gladly trade a bit of counter space for the convenience of a 22oz water tank that minimizes refilling interruptions.
My only minor gripe is that the 7 included tips, while great for variety, can be cumbersome to keep organized and swap between during a cleaning session. An accessory storage case would have been a welcome addition to prevent losing tips.
But overall, the Aquarius WP-660 lives up to its premium billing by providing a supremely customized yet simple flossing experience. If optimizing gum health and thorough cleaning is the priority, this model delivers in spades.
Unpacking the Ultra WP-100 Water Flosser
On the flip side, we have the Waterpik Ultra WP-100 – the brand’s budget-friendly entry point into the world of water flossing. While lacking some of the bells and whistles of the Aquarius, it delivers core cleaning performance in a trim, travel-ready package.
Key Benefits of the Ultra WP-100 for Daily Use
For a sub-$100 price tag, the Ultra WP-100 covers all the basics quite admirably:
- 10 pressure settings from 10-100 PSI
- 3 color-coded flossing tips (classic jet, plaque seeker, orthodontic)
- Shootings 1400 pulses per minute
- 16oz water reservoir with top-down filling
- Automatic 1-minute timer
In my hands, it feels every bit as well-built and sturdy as pricier Waterpik offerings. The pulse force remained impressively consistent even on max pressure, blasting out stubborn bits with ease.
And while the tank is on the smaller side, I appreciated the top-down filling design that avoids having to remove/tilt reservoirs like on some other models.
Comparing WP-100’s Water Reservoir and Tips
Speaking of reservoirs, the 16oz capacity is about average for entry-level countertop irrigators, providing enough water for a single full-mouth flossing session before needing a refill.
Frequent flossers may find themselves refilling more often compared to the Aquarius’ larger 22oz tank. But that compact size also allows the Ultra to take up less valuable counter space for those in tighter bathrooms.
In the tip department, the Ultra keeps things simple with its classic jet tip for general use, a plaque seeker for targeting specific areas, and an orthodontic pick for braces/aligners. It covers the core needs without overloading you with varieties you may not need.
An included tip storage case also ensures these colored tip attachments stay neatly organized – a big quality-of-life perk the Aquarius oddly lacks.
The Price Point and Value of Waterpik Ultra
But the Ultra WP-100’s strongest selling point may be its incredible value proposition at just $-$$. You’re essentially getting 80-90% of a premium flosser’s cleaning performance at a third of the price.
For users looking to experience the benefits of water flossing without breaking the bank, there really isn’t a better entry point than this versatile yet affordable pick from Waterpik.
Of course, you do sacrifice some advanced functionality like the Aquarius’ massage mode and accessory buffet. But if basic, no-frills flossing is the goal, the Ultra WP-100 absolutely delivers.
Comparing Features: Aquarius WP-660 vs Ultra WP-100
Now that we’ve covered the core user experiences of each flosser, let’s directly compare and contrast some of their key features side by side.
Countertop Design: Which is More Convenient?
The Aquarius WP-660 adopts Waterpik’s classic countertop profile with a large oblong reservoir jutting out from the cylindrical base unit. It has a substantial footprint that commands quite a bit of counter space.
The Ultra WP-100 opts for a much trimmer, oval-shaped design that minimizes its countertop footprint. Its reservoir attaches at the top rather than protruding outward.
So in terms of conserving counter real estate, the Ultra’s smaller profile gives it the edge – especially for bathrooms with limited flat surface areas.
However, that reduced size comes at the tradeoff of water capacity, with the Ultra packing a 16oz reservoir compared to the Aquarius’ spacious 22oz tank.
Performance Battle: Power Modes and Pressure Settings
Both units offer the same impressive 10 pressure settings ranging from a light 10 PSI up to a potent 100 PSI for tackling serious buildup. This level of adjustability ensures an optimal cleaning experience for everyone from first-time flossers to hardened plaque battlers.
Where the Aquarius WP-660 separates itself is in its inclusion of a dedicated “Massage Mode” designed to increase gum circulation. By alternating short and long pulses, it provides a gentle yet stimulating gum massage as you floss.
The Ultra sadly lacks any specialized modes beyond its standard flossing operation. It’s strictly a one-setting pony focused solely on dislodging debris rather than optimizing overall gum health like the Aquarius aims to do.
In terms of raw water pulsing power, both flossers operate at an impressive 1400 pulses per minute using Waterpik’s patented pulse-modulation technology. This consistent, high-powered pulsing helps maximize plaque removal even in the tightest interdental spaces.
Accessory Count: Which Model Offers More?
One major differentiator is the sheer number of included accessories and tip options in each package. The Aquarius WP-660 comes loaded with:
- 7 different flossing tips (3 classics, plaque seeker, tongue cleaner, orthodontic)
- Tip storage case
- Instruction manual and reference materials
In contrast, the Ultra WP-100 strips things down to just:
- 3 tip options (classic, plaque seeker, orthodontic)
- Tip storage case
- Instruction booklet
So while the Ultra covers the core flossing needs quite well with its trio of tips, the Aquarius gives you double the variety to customize your cleaning routine. From targeting tongue buildup to attacking plaque in specific areas, those extra specialized tips really do expand your coverage options.
That said, for basic interdental cleaning, the Ultra’s simplified 3-tip assortment may be all you really need without getting bogged down in accessories.
What to Look for When Buying a Waterpik Water Flosser
With a better understanding of how these two models compare, let’s discuss some broader factors to consider when shopping for any water flosser – whether from Waterpik or another brand.
The Importance of Choosing the Right Tips and Accessories
As we saw with the Aquarius’ bonanza of included tips, the types of flossing attachments can greatly enhance or limit your overall user experience.
At the bare minimum, look for an option that includes a classic jet tip for general interdental cleaning duties as well as a more focused “plaque seeker” tip for targeting stubborn buildup in grooves and pockets.
From there, any additional specialty picks for things like orthodontics, tongue cleaning, gum massaging, or implants are nice extras to have for tackling specific oral care needs.
Evaluating Ease of Use and Maintenance
Usability factors like controls, grip ergonomics, and reservoir design can also seriously impact how pleasant – or cumbersome – a water flosser feels to use on a daily basis.
Intuitive pressure adjustment and mode switching is a must, as is a secure non-slip grip for maintaining control during use. And the ability to quickly refill reservoirs with splash-free operation elevates the user experience.
Flossers that include accessory storage cases gain bonus points too for keeping tips organized and easy to swap between.
Why Size and Countertop Footprint Matter
Bigger certainly isn’t always better when it comes to water flossers, especially for bathrooms with limited counter space.
Streamlined, compact units tend to be preferable for most users as they can easily tuck away when not in use and take up minimal real estate day-to-day.
However, that portability often comes at the sacrifice of a smaller water reservoir that requires more frequent refilling during brushing sessions. Larger families or households may appreciate the convenience of an extra-large tank to minimize interruptions.
So evaluate what trade-off makes more sense for your cleaning routine – saving space or going for maximum tank capacity for fewer refills.
