Burst Water Flosser review 1

The most powerful cordless water flosser - 160PSI

star star star star

A stylish and strong performing water flosser, Burst boasts excellent battery life and USB charging.

As powerful as the water jet is, it drains the small the 110ml water tank in as little as 20 seconds, meaning multiple refills to complete a flossing session.

Consider these flossers as alternatives

If I were to buy a water flosser, the Waterpik Cordless Advanced would be my choice.

It is by no means the cheapest, but it is our number 1 choice for the best cordless water flosser

The handle is grippy and easy to hold. The water tank is a good size and the nozzle rotates easily.

The Sonicare Cordless Power Flosser 3000 is also a very good option.  Similar to the Advanced, it offers a X shaped water stream and has a built-in timer as well as a larger water tank for longer flossing times.

Design, usability, clean & general use

This water flosser or oral irrigator if you prefer, comes packaged in a simple cardboard box.  It is very similar to the Burst sonic toothbrush.  

It appears a bulky box, but it is by the very nature of the design of cordless water flossers.

Able to be held and used in 1 hand, water flossers are much larger than the likes of an electric toothbrush.  This is because of the water tank, pump etc that is all built into the handle.

This Burst option comes with the essentials you need to get up and running.

Burst Cordless Water Flosser

I have the black color option, but you have the choice of white and rose gold too.

The overall design is very similar to any other products of this type.  But, there are elements which are unique to Burst and tie in with their overall theme.

Most noticeable design accents include:

  • The diamond textured grip around the top part of the handle
  • The smiley face on the power button 
  • The icons for the different modes 

I like these subtle touches.

The hands-on pictures best describe the way the unit looks.  There are 3 key pieces to the unit.

Part 1 ins the main cordless water flosser handle.  Part 2 is the water tank/reservoir that connects to the handle.

Part 3 is the detachable tip or nozzle positioned at the top of the handle.  The nozzle directs the water into the mouth, having been pumped from the tank by the handle.

The base of the flosser is flat, with 4 rubber feet so it stands upright and doesn’t slip about on a flat surface.

Burst Water Flosser Base

The handle itself is quite curved, but there is a bulbous design to the handle.  The deepest part is the base/back of the unit slimming towards the top.

On the front, you have the power/mode button in the upper third.  This has the Burst smiley face on it.  It also has a ring of white light that shines around it when switched on.

Below this is a thick strip of light grey silicone rubber that helps achieve a secure hold of the unit in hand.

In the lower third of the front, you have 4 icons to depict the 3 modes and the battery status.

On the rear at the top is the button to release the nozzle.  In approximately the middle is the small port into which you connect the charging cable.  Below this then sits the 110ml water tank.

You can unclip the water tank, by sliding a switch on the bottom of the unit.  You don’t need to unlock and completely remove the reservoir though to refill it.  There is a door on the back of the handle that allows you to fill it with water whilst it remains attached to the handle.

It is not small because of what it is.  If you travel with such it will take up a reasonable amount of room in a suitcase or holdall.  Burst do provide a drawstring pouch case to hold the flosser and its accessories.  This makes transportation a little more convenient.

I like that you get a travel pouch included, it is a small and useful inclusion.

To turn the water flosser on, you need only a single press on the power button.

Burst pouch for water flosser

It bursts (excuse the pun) into life immediately.  It takes its power from the built-in rechargeable battery.

The flosser will turn itself off automatically after 45 seconds.  This happens irrespective of the mode or what water remains in the tank.

There are 3 different modes or pressure settings if you like on this unit.

They are:

  • Turbo
  • Standard
  • Pulse

To change the mode, you need to press and hold the power button.  It will then cycle through the modes illuminating the relevant icon with a white light. To lock in a mode, you just release the power button once the mode you want is selected.

The top icon, the full white circle is the Turbo mode.

The 2nd icon down, the ring icon is the standard mode.

The 3rd icon down, the dotted circle is the pulse mode.

The 4th icon, a + is for the battery and is not another clean setting.

Cleaning modes icon on Burst flosser

I would suggest the names of the modes printed on the handle would be marginally more user friendly.  Though these icons are consistent with the Burst toothbrush.

The water flosser will remember the last mode used.  You do not have to change the mode each time you use the flosser, unless you are specifically wanting to change it.

Although referred to as modes these are essentially different pressure settings.

Turbo mode is the most powerful.  This will give you maximum effect for removing plaque. I was surprised at just how intense the power was.  It offers 160 PSI.  That definitely clears the plaque and debris away.

To put this into context, the market leading water flosser brand is Waterpik. Their units typically have pressure settings from 0-10.  These setting range from 10 PSI through to 100 PSI.  Burst offers an extra 60 PSI.

You, like me I suspect will prefer the standard mode.  I am not sure of the precise PSI here, but I would guess it is around the 100 on offer from comparable models.  It is still powerful but a little less intense to use.

Pulse mode is designed to act more like a massage for the gum tissues.  It still cleans well but is a little less powerful. As the name implies, there is a pulsing to the water flow. You get shorter more intense bursts followed by a moment of more gentle water flow.

You don’t get any more granular control on this cordless unit.  

Handle of the Burst flosser

If you want very precise control, you will need to look at a countertop unit.  These more often than not offer more pressure settings.  Most cordless options like this only offer 1 or 2 modes.

When switched on, this is quite noisy. It is essentially a water pump.   It produces noise at around the 78db.

As standard, it comes with 1 tip/nozzle.  This is called the classic tip.

This is suited to most users for everyday use.  It can work with any mode, although Burst suggests it is best suited to the standard mode.

There are 2 optional tips.  These are Perio and Ortho.

Perio is designed for those with sensitivity.  It has a soft silicone tip to the nozzle.  This is designed to help massage the gums and reach into the pockets between the teeth and gums. It will also clean in crevices and other problem areas.  Pulse mode is best matched to this tip, but of course, you can use any mode.

Burst nozzles

The Ortho tip is designed for those with braces and other dental work.  There is a cluster of bristles at the tip.  These help sweep around fittings such as brace attachments.  It is also suited to those with bridges and implants.  It is ideally paired with the turbo mode.

Each of the nozzles clips into the top of the water flosser and lock in place.  You need to press the button on the top of the unit to unclip the tip.

When fitted, they can rotate a full 360 degrees, although it is not that easy to rotate.  They have a tight fit and I couldn’t easily twist them whilst in use.  Really you need to rotate the nozzle when out of the mouth and the unit powered off.

Some Waterpik models offer this option.  I would argue twisting those when in use is a little easier.

Do refer to the ‘how to use’ section earlier in the review to see how best to clean in and around the mouth using Burst.

Nozzle connection of Burst flosser

Water flossing by its very nature is a bit messy.  It can take some practice to get it right, so the first few days, do expect to be making a bit of a mess.  This happens irrespective of what brand or model you go for.

It is, in the long run, easier than most people than using floss, but it is less convenient and more expensive.  

Using a water flosser is better than nothing at all. Although, most dental professionals, advize using such in addition to regular flossing.

It is recommended to replace each nozzle every 6 months or 180 days.  If you subscribe to Burst, you will get a new one delivered to your door every 6 months at a cost of $6 a time.

You can cancel the subscription and make one-off purchases of nozzles at a cost of $7 each.

To fill the tank, you need to open the door on the rear of the unit.  This is a very secure fitting rubber seal.

I am a being a bit picky, but it can be a bit awkward to open. It is a tight fit and you need to get your nail/fingertip in under the edge to then grip it and pull it open.

Water tank seal Burst flosser

You need to keep your finger on this to keep the door open whilst you fill it. The design is such that if you let go, it flips back closing, but not completely sealing the water tank.

Most others have a plastic hinged door that folds back against the water tank.  This means you don’t actually have to hold it open.

It is a small but noteworthy frustration I have with this.  But, in fairness, it looks smart and securely fastens.

Perhaps the biggest negative is the 110ml/3.9 ounce water tank is small. 

 The following list shows how long (approximately) it takes to empty the tank on each mode. 

  • Turbo - 20 seconds
  • Normal - 25 seconds
  • Pulse - 30 seconds

For most people, this is not enough time to get the thorough clean/flossing that they want.  It is going to mean refilling the flosser at least once. 

You might not think this is an issue, but many will.  Even if you don’t need it to last as long as a minute, I think most need about 40 seconds or so to get the clean they want.

Waterpiks equivalent to Burst is the Cordless Advanced and this has a 210ml/7 ounces tank.  

If you go for a countertop option, this would offer up to 90 seconds of usage time. These have tanks of 600ml+.

You should fill the tank with room temperature water or warm water.  This is the advice from Burst.  They do not recommend filling it with mouthwash or even a diluted mix of mouthwash.

The whole unit is water resistant. Therefore if you like to floss in the shower you can do so.  You don’t need to worry about water running down the handle, it is protected.  It is not completely waterproof though, so a swim at the bottom of the tub is not what this is designed for.

The Burst flosser has been designed to last and gives no reason to be concerned about its, reliability.  If you remain subscribed to the nozzles, your warranty will last a lifetime which is great for peace of mind.

Battery life

The Burst water flosser has a built-in rechargeable Lithium-Ion (Li-Ion) battery.  It is not user removable.

This battery enables it to be cordless.  You are not tethered to a power outlet with this irrigator.

The claimed battery life is 80 days on a full charge.

It is not clear what this 80 day period is based on. Burst gives no more specific information. Is this 1 or 2 users per day? A single fill each use or multiple?

In my hands-on testing, the battery lasted a whopping 285 sessions using the standard mode.

Each session lasted 45 seconds.  

This is the time it takes for the water flosser to turn itself off automatically after having been powered on.

Power connector on Burst water flosser

Even on the most gentle pulse mode, the tank has drained in approximately 30 seconds.  So, each session isn’t going to last 45 seconds, unless you refill the tank.

The standard mode drains the tank in about 25 seconds.

Therefore by my calculations, if you used the Burst water flosser on the standard mode, twice a day and each time you filled the tank twice, the battery should still last over 120 days.

Quite simply this is excellent.  

I am not sure if all units will last this long, but even if they last 80 days, this is still superb.

This is well over what I would suspect anyone would require from the battery of a cordless water flosser.

When the power is running low, the ‘+’ icon on the front will be lit a solid red color.  This comes on when the remaining battery is at 20% or less.

When on charge the icon will remain red until the battery is fully charged at which point it will turn green.

It will take approximately 6 hours to fully charge the Burst water flosser.

To recharge it, you use the provided USB cable.

A proprietary cable it has a male USB A connection at one end and a barrel pin connector at the other.

Burst Water Flosser Power Cable

The barrel connector should be pushed into the charging connector on the back of the burst handle.  It is quite well hidden and is a neat solution.  It certainly should not succumb to water damage.

Being a cable specific to this device, it could easily be mislaid or lost, particularly as it is so infrequently that you will need to charge it.  This is just something to bear in mind.

You can charge the flosser via a USB port on a computer, battery bank or wall outlet.  But, included in the box is a 2 pin US USB plug adapter, so you can just connect it to the wall if you would prefer.  The plug adapter itself is color matched to the handle and support 110-240v.

Summary of battery life

Built-in rechargeable battery battery
Claimed 80 days of battery life
Achieved 285 sessions or 142 days if used twice a day
Red icon when the battery is at 20% power or less
USB charging
USB plug adapter provided
6 hours to recharge the battery

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.

The retail price of the Burst water flosser is $69.99.

Your perception of the price may well be different to mine, but it is comparably priced than a decent electric toothbrush.

By water flosser standards this could be considered a fair price. But it is certainly at the higher end of the price range within the cordless choices.  Corded or countertop flossers tend to retail for a bit more.

If you want to opt for the rose gold color option you actually have to pay a further $10 premium despite no technical differences between the variants available.

Unlike the Waterpik Cordless Advanced that has a retail price of $99.99 but sells for around $70, Burst is not subject to significant discounts.  Most of the time you will find it being sold at retail price.

The Burst irrigator comes with 1 nozzle/tip included in the box and you are automatically subscribed to replacements at a cost of $6 every 6 months (180 days).

You can cancel the subscription and purchase as a one-off, but each tip will cost $7 in this instance.

Waterpik does not offer their tips on subscription, but the nozzle price works out at $5 each.  Therefore there is a very slight difference in price between them, but it is a small premium to pay for the convenience of regular and timely deliveries, with no thought or effort on your part.

To help give a benchmark cost, we like to price products over a 3 year period here at Electric Teeth.

If you paid the full retail price of $70 and then purchased replacement tips without subscribing you are looking at a cost of $105 or $0.10 per day.

Save 10% on the purchase price and subscribe and that cost drops to $93 in total and $0.08 per day.

Purchase with a Burst ambassador code and you can get $20 off the retail price.  Assuming you then remain subscribed to replacement tips, the ownership cost is $80 or $0.07 per day.

Waterpiks Cordless Advance comes in at $0.09 per day over 3 years.

Compare this to traditional string floss that works out at about 2-3 cents per day and it’s about 2-3 times more expensive.

It is worth noting that there are some other brands, arguably lesser known that are more cost effective.  

You can get cordless flossers for $30-40.  

They do the job and offer a comparable clean.  The drawback tends to be the warranty/support, materials, and availability of replacement nozzles.  Some are better than others admittedly.  

I guess what I am saying here is that if you are on a tighter budget, you can still get products like this.

It is without a doubt a luxury and by no means essential. However, there are potential health benefits, that will for many, make this a worthwhile investment.

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 $69.99
Replacement nozzles $6 each with subscription, $7 without
Daily cost around $0.08 over 3 years
Comparably priced to Waterpik equivalent

Reliability & long term use

I have only been using the Burst flosser for a couple of weeks.  

During this time I have had no reason to call into question the quality and long term reliability.

It looks and feels well built.

The seal on the water tank is good and the nozzles fit securely.

The overall build is much better than some of the cheaper alternatives I have used. I certainly feel it is on par with the models Waterpik offers.

How well will it last, only time will really tell.  If their sonic toothbrush is anything to go by, I do believe it should perform well.

Burst offers a lifetime warranty, providing you remain subscribed to their nozzle deliveries.

You can purchase it without subscribing or cancelling the subscription plan.  In this instance, you get a 2 year warranty which is fairly comparable to other options.


Water flossers can be a great addition to a regular flossing routine. 

The Burst water flosser really is impressive and it exceeded my expectations.

It really does compete with the best cordless options available today.

There are more affordable options available that perform well.  But, for peace of mind and the benefits that come with subscribing, the Burst might well be the right option for you.

You could certainly do a lot worse.

How can I replace the batter of the burst flosser? My unit discontinued working and is now unchangeable. Simply stated: dead. I believe the battery is dead and I need a new one in order to continue to use this burst. I hate buying a new one every year. Please tell me how I can have a new battery installed.

Hi Carol. I don't believe there is a way to replace the battery yourself. Have you tried contacting Burst about this? How long have you had it? It may well be under warranty still.

I don't know for sure Sebreena, but I would imagine if you contact Burst they will be able to supply a replacement cable.

160psi? You guys tested it to be true? So this is more powerful than even the waterpik tabletop models?

Jon Love - Chief tester
January 30, 2021

Hi John. We don't have the tools to test the PSI accurately on the flosser. This is the quoted figure Burst give. My own testing confirms the pressure is very high. The intensity was stronger than a Waterpiks.

How is the noise level compared to waterpiks wp560 and wp660?

Jon Love - Chief tester
January 30, 2021

Hi John. I don't have a WP-560 to hand to check, but the WP-660 comes in around 65 decibels. So this is about 10 decibels quieter. I have tested the Waterpik Cordless Freedom and that comes in at around 73 decibels. So quite than Burst but not as quiet as the countertop WP-660.
