Waterpik Aquarius vs Cordless Advanced in Canada is mostly a bathroom-space decision: the Aquarius WP-660 gives you the larger countertop reservoir and more pressure settings, while the Cordless Advanced 2.0 WP-580 is easier to move, store, charge and use in tighter bathrooms.
If you are choosing between these two Waterpik models, do not start with vague claims about which one is stronger or more popular. Start with the routine. Do you have a permanent counter spot near a North American outlet, or do you need something rechargeable that can live in a drawer, toiletry bag or shared bathroom cabinet?
This guide compares the listed specifications, Amazon.ca product identity, official Waterpik Canada details, reservoir capacity, controls, charging, included tips and bathroom fit. It is a buying guide based on listed information, not hands-on testing or dental advice.

Products Compared
Waterpik Aquarius Water Flosser WP-660
The Aquarius is the more complete countertop setup. Waterpik Canada lists a 651 ml reservoir, 90 seconds of capacity, 10 pressure settings, 7 included tips, a 360-degree rotating tip handle, on-handle water control, a timer/pacer and two modes: Floss and Hydro-Pulse Massage.

Where They Differ
For Waterpik Aquarius vs Cordless Advanced in Canada, the important split is not brand. Both are Waterpik models. The real decision is capacity, controls, power setup and where the unit will live between uses.
Countertop capacity versus handheld convenience
The Aquarius has the larger listed reservoir by a wide margin. That matters if you want one longer sink routine without thinking about refills. The Cordless Advanced 2.0 has a smaller removable reservoir, which is part of why it is easier to carry and store.
10 settings vs 3 settings
The Aquarius gives more adjustment range on paper. The Cordless Advanced keeps the control path simpler with three settings. More settings are useful if several people use one unit; fewer settings may be enough for a personal travel-style unit.
Outlet spot vs charging routine
The Aquarius is corded and listed for 120VAC/60Hz use in North America. The Cordless Advanced uses a rechargeable lithium-ion battery and magnetic USB charging. Pick the routine you will actually maintain.
Countertop base vs drawer-friendly body
The Aquarius is not huge, but it still wants a permanent spot. The Cordless Advanced is taller in listed height, yet narrower and lighter, so it is usually the easier shape for bathrooms with little counter space.
Individual Product Breakdowns
Waterpik Aquarius WP-660: the better fixed-counter choice
The Aquarius is the model I would start with for a main bathroom where the water flosser can stay plugged in and ready. Its listed 651 ml reservoir, 10 pressure settings, 7 tips and timer/pacer make it the more complete shared-bathroom setup on paper.
The key advantage is not only reservoir size. It is also the control layout. Waterpik Canada lists an on/off water slider on the handle, 360-degree rotating tip, two flossing modes and LED function indicator. For a household where more than one person may use the unit, that broader setup makes sense.
Waterpik Cordless Advanced 2.0 WP-580: the better compact-bathroom choice
The Cordless Advanced 2.0 is the model I would look at for smaller bathrooms, renters, travel, shared counters and anyone who does not want another corded appliance beside the sink. Waterpik Canada lists waterproof shower use, global voltage compatibility, a travel bag, travel plug, tip storage case and magnetic USB charging.
The listed reservoir is much smaller than the Aquarius at 207 ml, so this is not the obvious pick for someone who wants the longest uninterrupted routine. Its appeal is convenience: lighter weight, narrower listed base width, rechargeable operation and an easier storage shape.
Decision Guide
The cleanest way to decide is to picture tomorrow morning. If the device has a stable home beside the sink, the Aquarius makes more sense. If it needs to disappear after use, the Cordless Advanced is easier to live with.
For one main bathroom
The larger tank, more settings and corded setup fit a regular counter spot better than a pack-away routine.
For limited counter space
The narrower body, lighter weight and charging setup suit small bathrooms, shared vanities and travel bags.
Pick Aquarius if…
- You want the larger 651 ml listed reservoir.
- You prefer 10 pressure settings instead of 3.
- You have a dedicated counter spot near a North American outlet.
- Several people may use the unit and included tip count matters.
Pick Cordless Advanced if…
- You want a rechargeable unit that stores more easily.
- You travel or want global voltage compatibility.
- You prefer a smaller bathroom footprint.
- You value the listed shower-use design and travel plug.
Buying Advice for Canadian Shoppers
Before buying either model, check your bathroom layout first. The Aquarius is the easier pick when counter space and a nearby outlet are not problems. The Cordless Advanced is better when the bathroom already feels crowded or the unit needs to move between home, gym bag and travel bag.
Reservoir size deserves more attention than it usually gets. The Aquarius lists 90 seconds of reservoir capacity, while the Cordless Advanced lists 45 seconds. That does not make one automatically better, but it changes the routine. Larger capacity favours fewer interruptions; smaller capacity favours portability.
Also check the current Amazon.ca listing carefully for the exact colour and package version. Waterpik models can appear in different colours or bundles. This guide uses the WP-660 Aquarius listing with ASIN B00HFQQ0VU and the Cordless Advanced 2.0 white listing with ASIN B01GNVF8S8.
For any dental condition, appliance, implant, braces or sensitivity concern, use the current product manual and advice from a dental professional. This article is about listed product differences, not treatment guidance.
