Can we shave our flossing to 60 seconds and still get dentist‑level clean — should we pick Waterpik’s power or AirFloss’s speed?
Ready to ditch string floss? We compare the Waterpik WP-660 and Philips Sonicare AirFloss to help you choose the best water flosser for your routine — countertop power, cordless convenience, travel portability, or targeted gum care, and save time with us.
Family Favorite
We appreciate the unit’s strong cleaning performance and wide range of pressure settings that suit many users and needs. Its large reservoir and included tips make it great for families, but the countertop design and higher noise level reduce portability and discreetness.
Travel Ready
We like the cordless convenience and Quad Stream cleaning action that makes quick, effective spot cleaning very simple. It’s a strong travel option with good battery life, though the small reservoir and a few reliability complaints mean it’s not ideal for everyone.

Waterpik Aquarius vs Sonicare Power Flosser 3000: Which Reigns Supreme?
Design, Build and Ease of Use
Waterpik Aquarius (WP-660)
The WP-660 is a classic countertop unit built for at-home families. Its larger 22 oz reservoir sits on the base and gives us ~90+ seconds of continuous flossing — enough for a full one-minute routine without refilling. The front dial and clear mode labels make swapping between 10 pressure settings and Massage mode straightforward for different mouths. It’s heavier and louder than cordless options, but the stable base and 360° rotating tip handle make reaching back teeth easy for multiple users.
Philips Sonicare AirFloss (Cordless Power Flosser 3000)
The Sonicare AirFloss is compact, cordless, and designed for one-handed use. Its slim body and IPX7 waterproofing let us use and rinse it freely — and toss it in a toiletry bag for travel. The removable 8 fl oz reservoir is smaller (about a 1-minute run time), but the quad-stream nozzle covers more surface area per pass. Setup is minimal: charge via USB, snap on a nozzle, and go. It’s quieter and lighter, but expect more frequent refills and to store it upright or in a pouch.
How they fit into daily life
If we want a powerful, family-ready unit that lives on the counter, the WP-660 wins on capacity and multi-user features. If portability, quiet one-handed operation, and travel convenience matter most, the Sonicare AirFloss is the better fit.
Cleaning Performance and Oral Health Results
Waterpik Aquarius (WP-660)
We find the WP-660’s PrecisionPulse pulsed water pressure and 10 adjustable settings give us a highly controllable, deep clean. The continuous pulsating stream dislodges plaque along the gumline and drives fluid into pockets — which is why Waterpik cites up to 99.9% plaque removal in treated areas and ADA acceptance for safety and effectiveness. For braces, implants, and periodontal care the higher pressure range and steady stream are especially effective at flushing food and biofilm from hard-to-reach spots.
Philips Sonicare AirFloss (Cordless Power Flosser 3000)
The AirFloss uses Quad Stream technology (four simultaneous jets) plus two flossing modes and three pressure levels. Its burst-style delivery can cover more interdental surface per pass and — when used correctly and consistently — can match traditional string floss for everyday interdental cleaning. The pulses are gentler and more targeted than a countertop flosser, which makes it ideal for quick daily maintenance and sensitive gums.

Side-by-Side Feature Comparison
Value, Price and Who Should Buy Which
Price vs. long‑term value
We compare sticker price and practical return. The Waterpik WP-660 runs around $80 and gives a countertop powerhouse with a large reservoir and 7 tips — that up-front investment buys customization, multi-user capability and clinical-level cleaning. The Philips Sonicare AirFloss 3000 is about $69 and gives cordless convenience, quieter operation and a travel-ready design. For households that actually use it daily, the WP-660’s stronger performance and tip variety deliver better long‑term oral-health value; for single users or frequent travelers, the AirFloss’s portability and ease of use justify its price.
Ongoing costs and practical upkeep
Both systems require periodic nozzle/tip replacement and basic cleaning. We recommend replacing Waterpik tips every 3–6 months and Sonicare nozzles roughly every 6 months. Replacement packs for either brand are widely available online; Waterpik’s wider tip selection can mean slightly higher ongoing spend if multiple users buy different tip types. Battery upkeep for the AirFloss (USB charging) is minimal; the WP-660 has no battery cost but needs counter space.
Who should buy which
Final Verdict — Which One We’d Choose
We choose the Waterpik WP-660 as our overall winner. Its countertop power, broad pressure range, seven tips for multiple users, and ADA acceptance make it the top pick for families, people with braces, and those with periodontal needs.
That said, we recommend the Philips Sonicare AirFloss if portability, simplicity, and quick daily maintenance are your priorities. It is compact, cordless, and travel friendly, making daily flossing effortless. Choose the Waterpik for power and clinical versatility, or the AirFloss for convenience, then stick with it daily and your gums will thank you. If you want our explicit pick, we give the overall nod to the Waterpik WP-660 for superior cleaning power, pressure control, multiple tips for families, and proven clinical acceptance; pick the Sonicare AirFloss only when you prioritize portability and ease on the go.

Both are expensive when you add tip replacements and the occasional new battery/charger.
I like the Waterpik’s effectiveness but hate the noise (it sounds like a tiny aquarium). The AirFloss is quieter but I question long-term durability.
Anyone tracked the cost of ownership over 2 years? I’m trying to justify the initial outlay.
Don’t forget warranty and sales — snagging a sale or bundle with extra tips can cut costs a lot. I waited for a holiday deal and saved 30%.
I added it up once — Waterpik + tips (every 6-9 months) came out a bit higher than AirFloss if you’re single. If you have a family, Waterpik is cheaper per person.
Good question. Over two years: factor in replacement tips (Waterpik tips are cheaper per piece but you may use more), electricity negligible, and for AirFloss possibly a replacement unit if the battery degrades. Many users report AirFloss batteries hold up ~2-3 years depending on usage.
Long post but helpful — thanks for the side-by-side.
I’ve used a Waterpik (not the WP-660 specifically) for years and the big tank + pressure settings are a game changer for my gums.
The WP-660 sounds like the dentist-approved swiss army knife: 7 tips for the family, 10 settings… but yeah, it’s bigger and takes up more counter space.
Sonicare AirFloss is tempting for mornings when I’m running late — quick and less splashy — but I worry about how well it cleans between tight contacts.
Anyone else feel like the AirFloss is great for maintenance but not a full replacement for flossing after a long weekend of sweets? 😅
I second this. Had a filling pop once and the AirFloss didn’t reach the pocket the Waterpik did. But for travel? AirFloss wins hands down.
Totally — that’s a good summary. The WP-660 is generally better for deeper clean and users with braces or gum issues, while the AirFloss is designed for fast daily touch-ups. If you have tight contacts, many reviewers still prefer a full water flosser or string floss occasionally.
I use WP-660 in the mornings and AirFloss at work sometimes. Best of both worlds imo. Also — pro tip: keep extra tips stored in a little zip bag so they don’t get gross. 😂
Been a dentist office tech for 8 years — quick take:
Waterpik WP-660 is ADA accepted which matters for patients with periodontal issues. The pressure control and tip variety let you tailor therapy.
Philips Sonicare AirFloss is excellent for compliance — people actually use it. If your patient refuses string floss, AirFloss is better than nothing.
Downside of WP-660: more maintenance and counter space. Downside of AirFloss: limited tank, may require multiple bursts per interproximal area.
Neither is a perfect replacement for flossing in every case, but both have their place.
I tell friends: AirFloss for lazy days, Waterpik for Sunday deep-clean 😂
From a patient POV: I stopped bleeding after switching to Waterpik. Was skeptical but now I’m evangelizing it to coworkers.
Can confirm about the tank size — my girlfriend complains about filling the Waterpik. lol
Appreciate the professional viewpoint, Robert. The point about compliance is huge — a device someone will consistently use often trumps the ‘perfect’ tool they ignore.
One quick clinical note: for deep periodontal pockets, adjunctive irrigation (Waterpik) can help, but it doesn’t replace professional care. Always follow your dentist’s advice.
Honestly, I bought the AirFloss because I thought ‘quad stream’ sounded futuristic. Spoiler: it’s just water and a tiny jet lol.
But it cleans enough for me and my coffee stains. Battery life is decent too.
Ha — marketing does love a flashy name. Quad stream does provide multiple micro-streams, which can feel more efficient than a single jet, but it’s still aimed at quick, convenient use rather than deep irrigation.
Same here, Marcus. I was sold on the tech-speak. If you’re not dealing with gum pockets or braces, AirFloss is fine. Saves me time in the AM.
AirFloss owner here — love how small and quiet it is. Perfect for my tiny apartment bathroom.
Only gripe: having to refill the little reservoir every time is slightly annoying. But still better than dragging out a big machine.
That’s a common trade-off: portability vs capacity. The AirFloss is designed for quick, single-person use, so frequent refills are expected.
Try filling it right after brushing and leave it on the sink — it becomes a 10-second task instead of a chore.
