The buying question

Would a plug-in countertop station or a rechargeable handheld fit your bathroom, and which pressure-control and refill routine would you prefer?

Aquarius offers a separate hose-connected handle, more pressure settings and a larger reservoir. Pulse puts the water and controls in one rechargeable handheld body.

Quick verdict

Choose Waterpik Aquarius WP-662 if

  • You want the water tank to stay on the counter while you hold a separate handle.
  • You value more pressure adjustment positions and a larger reservoir.

Choose Waterpik Cordless Pulse 3100 WF-20CD010 if

  • You want to charge separately and use the handheld at the sink without a power cord attached.
  • You prefer a narrower base and are comfortable with Low/High controls and refilling as needed.

When to skip: Skip Aquarius if you cannot provide a suitable countertop position and North American 120V/60Hz supply.
When the recommendation changes
  • The intended Aquarius position cannot accommodate its base, hose and suitable power supply.
  • You need more adjustment positions than Low and High.
  • The available shelf is too low for Pulse with its tip fitted.

The differences that matter

Power And Sink Setup

Waterpik Aquarius WP-662

A corded countertop base supplies a separate handle through a hose. The US WP-662 requires 120V/60Hz power.[1, 2]

Waterpik Cordless Pulse 3100 WF-20CD010

A rechargeable handheld body contains the reservoir. Waterpik specifies USB charging and a separately supplied wall power adapter.[3, 4]

What this changes: Choose Aquarius for a regular sink station with a suitable outlet and room for its base and hose. Choose Pulse when you prefer to charge separately and bring the handheld unit to the sink.[1, 2, 3, 4]

The better fit depends on your priorities

Pressure Controls And Refill Routine

Waterpik Aquarius WP-662

Ten pressure settings on a base dial; the handle has a water on/off slider. The removable reservoir holds a listed 22 ounces (651 mL).[1, 2]

Waterpik Cordless Pulse 3100 WF-20CD010

Two pressure settings, Low and High, on the handheld slider. The removable reservoir holds a listed 6 ounces (177 mL).[3, 4]

What this changes: Aquarius suits a preference for more adjustment positions and more water in one fill. Pulse suits a simpler Low/High choice if you accept the smaller tank and refilling when needed. Setting count does not establish cleaning effectiveness.[1, 2, 3, 4]

The better fit depends on your priorities

Best for your routine

A regular countertop station with more adjustment choices

Best fit: Waterpik Aquarius WP-662

Based on listed features, not comparative testing.

Aquarius combines a separate handle, ten-position dial and larger tank. Allow space for the hose and base as well as access to a suitable outlet.

Charging separately from the sink you use

Best fit: Waterpik Cordless Pulse 3100 WF-20CD010

Based on listed features, not comparative testing.

Pulse operates as a rechargeable handheld. Its narrower base can suit a small storage spot, but check its taller tip-on height and accept the smaller tank.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If Aquarius costs more, weigh its extra adjustment positions and larger reservoir against the space and outlet it needs. If Pulse costs more in the offer you find, its value depends on wanting the rechargeable handheld arrangement.

Price-history evidence is insufficient to recommend buying now or waiting.

Limitations

  • We did not test cleaning effectiveness, pressure output, noise, battery endurance or long-term reliability. More pressure settings do not establish a dental-health advantage.
  • Waterpik describes Aquarius as offering 90+ seconds per fill and Pulse as up to 45 seconds. These are manufacturer descriptions, not a matched runtime test or a promise that one fill completes your routine.
  • Follow the supplied manual and your dental professional’s advice. Both manuals limit use to no more than five minutes in each two-hour period; this comparison does not recommend a treatment or a replacement for other oral care.

Questions shoppers ask

Does Aquarius turn off after its one-minute timer?

No. In Floss mode, the pauses at 30 seconds and one minute are prompts. The handle slider stops water flow while the motor continues; use the base power button to switch it off.

How does filling the two models differ?

Lift Aquarius’s tank off the base to fill it, then reseat it firmly. With Pulse, disconnect the charging cable and close the port cover before opening the reservoir flip top. Keep Pulse upright during use and refill as needed.

What should I check before charging Pulse?

Waterpik’s standard configuration does not include a wall adapter. Check the cable and the supplied manual’s adapter requirements before using an existing charger. The current instructions call for four hours before first use; keep contacts dry and close the charge-port cover flush before filling.

Can the reservoirs go in the dishwasher?

Both reservoirs can go on the top rack; air dry rather than use heated drying. The powered units stay out of the dishwasher and must not be immersed. Disconnect power or charging before cleaning and replace Pulse’s charge-port cover.
