Our recommendation
Buy the Aquarius if you have counter space: 10 settings, 7 tips, 90-second reservoir, and ADA acceptance make it the more capable flosser. Buy the Cordless Advanced if you will actually use it more: shower flossing and portability beat specifications for compliance. Many households sensibly own both.
Capability
The Aquarius offers 10 pressure settings (10 to 100 PSI) against the cordless model's 3, 7 tips against 4, and a 90-second reservoir against 45 seconds. For complex dental situations, braces, implants, periodontal pockets, the Aquarius's range is meaningfully better. For straightforward daily flossing, the cordless model's capabilities suffice.
Convenience
The Cordless Advanced is waterproof, outlet-free, and travel-ready; the Aquarius needs counter space, an outlet, and stays home. Shower use alone converts many skeptics: the mess concern vanishes. If your countertop flosser sits unused because setup feels like a chore, the cordless model wins on the only metric that matters.
Noise and footprint
The Aquarius pump is loud; the cordless model is quieter. The Aquarius claims permanent counter real estate; the cordless lives in a drawer or shower caddy. In small bathrooms these practical factors often outweigh the capability gap.

Choose Waterpik Cordless Advanced WP-560 if…
- You travel frequently or have a tiny bathroom

Questions, answered
Can the cordless model replace the Aquarius?
For basic daily flossing, yes. For specialized needs (orthodontic tip, Pik Pocket tip, massage mode), no. They are complements more than substitutes.
Which is better for beginners?
The Cordless Advanced: fewer settings to confuse, shower use is intuitive, and the lower friction means beginners actually build the habit. Upgrade to the Aquarius if you develop specific needs.
Do I need both?
It is a common and sensible setup: Aquarius at home for thorough routines, Cordless Advanced for travel and quick shower sessions. But one used daily beats two used sporadically.
