Waterpik WP-360 Review

Our Verdict

The fundamental principle of the WP-360 cordless water flosser is good.

The product works, but it is not great.

Build quality and reliability are so so and with a 1 year warranty does not match up to the 2 year warranty of other products.

The newer WP-650 is a much better buy.

The 3 BIG questions about the Waterpik WP-360

If you are short of time, the answers to the following 3 questions should let you know all you need to about the WP-360. If I have missed something, let me know in the comments.

If you want more detail, you can read the full Waterpik WP-360 review further down the page.

1. Is there anything drastically wrong with this water flosser?

No, there is nothing drastically wrong with the oral irrigator.

The WP-360 does the job it is designed for, but the reality is newer models are available and perform better.

2. Which other water flossers should I consider?

I strongly advise taking a look at 2 other Waterpik models, both of which are stronger options over the WP-360.

Most expensive is the WP-560, that has a built-in battery or you can also consider the Cordless Freedom WF-03, that is powered by user removable AA batteries.

If you’re considering the purchase of a new water flosser, I recommend reading our posts on the best electric flossers and the best cordless water flossers.

3. Where is the best place to buy the WP-360 water flosser?

Many of the big name stores, both online and offline stock the WP-360.

Aside from Amazon, you can find this in CVS pharmacies, Target, Walgreens, Walmart, and online at Jet

And now for a bit more detail….

Using water pushed out at pressure, the WP-360 can clean above and below the gumline, replicating what floss does.

Removing the plaque bacteria, with regular use you can be assured of a thorough clean and healthier gums.

Designed for use primarily at home this unit is wireless, giving you greater control and flexibility in its use.

Not laden with complicated features, it focuses on doing the job and doing it well.

What is the Waterpik WP-360 Cordless Water Flosser?

It is a handheld device that is made up primarily of a pump and a reservoir.

In the reservoir you place water and when powered on, the pump draws the water out and feeds it through a tube at the top of the flosser into the user’s mouth.

A powerful jet of water, it forces plaque and bacteria off and away from the teeth and gums.

The stream of water is often softer, less abrasive and a generally more enjoyable method of flossing for many.

How to use the Waterpik WP-360 Cordless Water Flosser

Make sure the unit is charged.

Step 1: Prep

Disconnect the power supply from the flosser, if on charge.

Attach the tip of your preference.  You will feel and hear it clip into place.

Step 2: Fill

Open the reservoir door at the top of the unit and fill the compartment with luke water until it is a little less than full.

Close the door to the reservoir.

Step 3:  Position

Place the tip of the flosser into your mouth.

Lean over the sink.

Close lips enough to prevent splashing, while still allowing water to flow from mouth into the sink.

Step 4: Clean

Power it on.

Aim water at the gumline at a 90 degree angle. Follow the gumline and pause briefly between teeth.

Here is a video demonstrating how to use it.

Pros & Cons

Here are a list of the pro’s and cons having used the Waterpik Cordless water flosser.

The Positives

  • Effectiveness & appeal – It takes a little practice to floss effectively and without making a mess, but it is a more comfortable and enjoyable way to floss or many.
  • Cordless – Not bound by wires you are free to move around when using this.
  • Rechargeable battery – A built-in battery is rechargeable.
  • ADA accepted – The American Dental Association (ADA) have given this their seal of approval.

The Negatives

  • Size – A bit chunky.  Not something you will necessarily want to throw into a weekend bag if you are traveling light.
  • Small tank – Holds enough water for up to 30 seconds, which is not really long enough.
  • Messy – Whilst you can master a technique, the steps involved and the amount of water pushed into the mouth means this is not the most enjoyable or flattering experience, you need a sink and even then you can make a bit of a mess.
  • Settings – Less control over pressure settings than other units.
  • Quality – Concerns over reliability

Design, usability, clean & general use

A more entry level cordless water flosser this is.  It does not offer quite the same level of features and benefits as the likes of the much more expensive Cordless Advanced WP-560 flosser.

In some respects this unit has been built to a price and it is not the best representation of quality and what is possible.

But, in its defense, it does what it is meant to and cleans the teeth and along the gumline well.

Waterpiks clinical research pages show just how effective it is.

Added reassurance comes from the fact that this and other Waterpik flossers have been awarded their ‘Seal of Acceptance’.

To achieve such accreditation, the product must demonstrate efficacy according to requirements developed by the ADA Council on Scientific Affairs.

Failing to clean properly between the teeth and gums can lead to a buildup of bacteria and plaque that in time, can  turn can result in gum disease.

The cordless flosser removes bacteria deep between teeth and below the gumline where brushing and traditional flossing can’t always reach.  The flow of water offers a varying pressure of 45 to 75 PSI that will massage and stimulate the gums to improve circulation and keep them strong and healthy.

The unit comes in one color option only, White, with the Blue water reservoir that sits on the back of the handle.

The unit looks fairly smart, if a little dated in the design.  There are more shapely models available.

At the end of the day, it is about doing a job and that is does.

At the very top of the unit is where the interchangeable tips or nozzles as I call them fit into.

They clip in place and are released via an eject button that sits at the very top of the front of the unit.

When clipped in place, the mechanism these tips sit in can be rotated, a full 360 degrees.

You will see a series of ridges on the circular ring where the tip fits.  These ridges provide grip and contact points to twist the nozzle into the perfect angle for flossing.

On the front of the handle is a small Blue panel.

There are 3 buttons within this panel, all of which are raised for easy recognition by the fingers and thumbs.

The top button is the eject/release for the nozzle, whilst a power on and power off sit below.

Labels for the on and off button are located to the right hand side.

Roughly halfway down the handle there is a slight kink as the body of the unit extends out slightly to accommodate the water reservoir on the back.

The unit is thicker at the bottom that it is at the top.

It has a wide base and will sit upright on a countertop.

Towards the bottom of the unit is the proprietary charging port, into which the supplied charging cable fits.

At the bottom, the White plastic construction stops and changes to the Blue colored plastic that forms the water reservoir on the back of the unit.

The water tank is detachable from the main unit and has a lid at the top that you open to fill with the water.

It is a tricky balance between size and portability.

The WP-360 measures in as:

  • Height (with nozzle) – 11.90 Inches (30.22 Cm)
  • Width – 1.82 Inches (4.62 Cm)
  • Thickness – 3.00 Inches (7.62 Cm)
  • Weight (with nozzle) – 3.00 Inches (7.62 Cm)

This water tank holds 5oz/150 ml which is about enough for 30 seconds of usage.

For most this is not enough to floss properly.

Many, myself included, typically want 45-60 seconds worth, so you could find you feel the same and have to refill the tank each time you use it.

This consequently can affect the battery life.

The lack of built-in timer and pacer also means it’s up to you, to ensure an even clean across the teeth and gums.

Unless you particularly need cordless, a countertop solution could be the one to go for.

The size does too mean it is not great for popping in a bag if you go away.  Frequent travellers may become frustrated by having to take the power cord too, due to the 7 day battery life and the lack of travel case.

But then again, this is not the most expensive flosser, so this is in part to be expected.

The fact the unit has a water tank plays a part too.  There is only so small it can be.

In the box comes 2 different nozzles or tips.

They are:

  • 1 x High pressure jet tip (JT-450E)
  • 1 x Low pressure jet tip (JT-360E)

As the names imply, depending on which you use will depend on the amount of pressure delivered through to your teeth and gums.

These are just 2 from a range of different tips available.

Other options, available for purchase separately include:

  • Classic Jet Tip (JT-100E) – For general use offering twice as effective results than string.
  • Toothbrush Tip (TB-100E) – For brushing and flossing at the same time.
  • Plaque Seeker Tip (PS-100E) – Ideal for those with implants, crowns, bridges or veneers targeting plaque in hard to reach areas.
  • Orthodontic Tip (OD-100E) – Great for those with braces offering up to 3 times more effectiveness than traditional floss.
  • Pik Pocket Tip (PP-100E) – Delivering medicament and rinsing deep below the gumline those with periodontal pockets and fucations benefit most here.
  • Tongue Cleaner Tip (TC-100E) – Freshens the breath by removing bacteria from the tongue’s surface.

The jet tips generally last about 6 months each, whilst the other more specialist ones last about 3 months.

A pack of 2 often costs $10, so $5 per tip.

From the moment you press that on button water will be pumped out through the jet tip, so be sure to place it in the mouth before turning it on.

It will take some time to perfect the technique and it can be quite messy the first few go’s, but you will get the hang of it.

Traditional string floss can often feel a more harsh and aggressive cleaning option, particularly in tight gaps.

Water flossing feels much softer and the rotating nozzle allows for a finer degree of control.

The unit itself if not water resistant, so should not be used in the shower.

Whilst the WP-360 does the job, the WF-03 from Waterpik is perhaps a better buy.

That model does use removable AA batteries, but comes with different pressure settings as well as a travel case.  Build quality feels a bit better too.

If you really want to invest, there is the Advanced Cordless, but this is very expensive, even though it does offer some benefits.  Read our review of that for more info.

Summary of design, usability, clean & general use

  • Cordless
  • Built-in rechargeable battery
  • A weeks usage time
  • No battery/charging icon
  • Takes 24 hours to charge
  • No pressure settings
  • Simple on and off buttons
  • 2 tips provided
  • Alternative tips available
  • Can rotate the nozzle
  • Holds 5oz/150 ml in the reservoir
  • Provides up to 30 seconds of constant water flow, will not be enough for some
  • Not the most glamorous tool to use – takes practice
  • Impressive clinical results

Battery life

Sealed inside the handle is a Nickel Metal Hydride (NiMH) battery that is rechargeable.

In the box with the unit comes a 2 pin US mains adapter.

At one end is the usual power adapter, at the other is the proprietary connector that fits into the port on the front of the unit.

It takes 24 hours to fully charge the unit.

The provided power adapter is suitable for US power supplies only and does not have voltage support for other parts of the world.

Once fully charged, you will get approximately 7 days use from the built-in battery, based on a single use each day.

Use it more regularly and you can expect to be recharging more frequently.

There is no charging icon to show when the battery is low or if charging of the battery is complete.  It is a bit of a guessing game.

When the power is low or running out you will feel the pressure of the water drop and the unit will at a point turn itself off.

Do not use it, whilst connected to the power.  Disconnect the charger and then use.

It would have been nice if the battery lasted longer, a week feels a bit on the short side.

If you are travelling for longer than a week, you will have to take the charger.

I have not suffered with any reliability issues with the unit, but some have reported poor performance and reliability issues with the battery.

Some have said the battery failed all together and would not power on, whilst others are getting poor usage time.

Don’t be too concerned, the unit does come with a warranty that will cover battery faults in most instances.

Summary of battery life

  • Built-in rechargeable battery
  • Gives a weeks usage time
  • No battery/charging icon
  • Takes up to 24 hours to fully charge the unit

Price & where to buy

I have included links to buying options here at the start of the review.

In the section below, I discuss the price more generally and in relation to similar products.

$37.99 is the retail price of the WP-360.

It’s stocked online at various retailers (see the price comparison below) and it’s always worth checking out eBay.

So no big savings to be had here.

You do need to consider in the price of replacement nozzles/tips.

A pack of 2 costs about $10 and last about 6 months each, so at $5 each they are fairly good value.  It does add to the lifetime cost, but you have this with other water flossers too.

Priced over a 3 year period as we like to do here at Electric Teeth, you are looking at an ownership cost of about $55 or $0.05 per day.

Compared to regular tape floss at is just 1-2 cents per day this my seem quite expensive, but you are paying for the convenience.

At the time of review, the WF-03 Cordless Freedom version from Waterpik is similarly priced and in my opinion the better buy, even if it doesn’t have a rechargeable battery built-in.

For a broader buying comparison, you may also like to check out our best cordless water flosser article.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • Recommended retail price of $37.99
  • Available for around $35-40
  • Replacement nozzles retail for $10 for a pack of 2
  • Daily cost around $0.05 over 3 years
  • WF-03 Freedom Cordless is a better buy

Reliability & long term use

The WP-360 comes with a 1 year warranty which is ok, but is not as great as the 2 years that now come with a lot of these types of products.

Whilst during my time with the flosser I did not experience any reliability issues, many have made comment about poor battery reliability among a few other random faults.

Of course, these products go through quality testing, but some standards are higher than others.

The overall build feels a bit cheap and this is not the best example of a Waterpik product.

Conclusion

The fundamental principle of the WP-360 cordless water flosser is good.

The product works, but it is not great.

Build quality and reliability are so so and with a 1 year warranty does not match up to the 2 year warranty of other products.

The newer WP-650 is a much better buy.

FAQ

  • How long does the battery last?
    • Based on 1 user per day you will get about 1 week from the flosser.
  • Does it come with a charger?
    • Yes.  The 2 pin US power adapter will charge the unit fully within 24 hours.
  • How often do the nozzles need replacing?
    • Nozzles should be replaced every 6 months.
  • Can I use mouthwash in the Waterpik?
    • You could, but it would be expensive and wasteful.  Best adding a dash into the water used in the reservoir for a burst of freshness.
  • How much water or mouthwash does it hold?
    • Approx 5oz/150 ml which will last for 45 seconds.
  • Can I use the Waterpik in the shower?
    • No, it is not water resistant for use in the shower.
  • Does it come with a travel case?
    • No, a travel case is not provided.
  • My gums bleed when I use cordless flosser. Is that normal?
    • Bleeding gums may be a sign of infection and a little bleeding can be normal when starting a new oral care routine, as you may be cleaning in areas not previously reached. However, if bleeding is excessive or does not stop within a few days of regular use, consult a dental professional.

  1. Given the height of the 360 flossed, many bathroom sinks are not deep enough to fill this unit since the reservoir opening is at the top. I use a measuring cup and fill and pour it twice for 1 minuet of flossing. Big issue, the on off switch frequently malfunctions. It doesn’t always come on when I I touch the button so I often have to hold the button down manually the entire minute of flossing. The switch is actually defective.
