Flossing is usually the first new year's resolution to fold under the pressure of a busy lifestyle, but water flossers are one way to futureproof your intentions (and your teeth). The best water flosser has an ample water reservoir and pressure range, with readily-available replacement heads. Because water flossers get into tight spots with ease, they're particularly ideal for people with braces, crowns, or dental implants. We've done the research, and here's our guide to Australia's best water flossers.

How we picked

To find the best water flosser in Australia, we started our research with weighing up important features. It quickly became clear that when it comes to water flossers, Aussies are concerned with the size of the water tank and the battery life. The bigger the tank, the less time-consuming refills you’ll be doing. The better the battery life, the lower the risk of it running out of juice, mid-floss.  We also read about quality concerns, especially around the plastic water tanks. We reckon as long as you follow the manufacturer’s instructions for care and maintenance, your tank should last. 

As well as paying attention to water tank size and battery life, we considered:

  • Personalised settings: the best cleans seem to come from the water flossers that offer the most personalisation. This is usually done by offering different power levels, pressures or speeds. This is especially important for people with sensitive teeth who might find the most powerful settings too painful.
  • Corded vs cordless: with a corded water flosser, you don’t need to worry about battery life. But you’ll have to make sure there’s space on your bathroom sink to hold what’s usually a bulky unit. A cordless one gives you better flexibility but the payoff is battery concerns. We aimed for a mix of both. 
  • Tips: most water flossers come with a range of tips. (Although our Philips Sonicare AirFloss Ultra top pick doesn’t. It opts for a nozzle instead.) Tips are good for targeting different needs - you’ll find tips that target plaque or clean braces, for example. 
  • A timer: a timer makes sure you spend the recommended 60 seconds water flossing. A pace or quad timer, that alerts you at 30 or 15 seconds, is even more handy to ensure whole mouth coverage. 
  • Reliability: how long will your investment last? We wanted to ensure all our picks are great, long-term. Heading to, where we read hundreds of hands-on reviews, gave us an idea of performance and reliability.
  • Price: finally, we considered price, ensuring we covered a range of budgets so that every Aussie mouth can enjoy a water floss. 

I, (Cosier writer Elese), have some hands-on experience with water flossers too. So, we took that into account when deciding our picks.

The best water flosser for most

Philips Sonicare AirFloss Ultra

Choose this if

One of Australia’s best-rated water flossers, the Philips Sonicare AirFloss Ultra is a crowd-pleasing pick that’ll suit most people. It’s compact and easy to use, with a 2-week rechargeable battery life and 3 modes to suit your preferences. Replacement heads are easy to find too.

What we love

Micro-Droplet Technology

Combines air and water to blitz debris from around your gums and teeth.

Triple burst settings

3 different burst options to customise your clean.

Easy to fill

Open the reservoir at the back, top up with water or a splash of mouthwash, and off you go.


No bulky countertop units makes this ideal for smaller bathrooms.

Rechargeable battery

More sustainable than buying new batteries with a solid 2-week battery life on a full charge.

The not so good bits


At around $190, it’s steeper than your average pack of floss, though pricing is similar to other water flossers. Besides, it may outweigh the cost of poor oral hygiene in the long run.

Additional specs

Ready to take the plunge with water flossing, but not sure where to start? The Philips Sonicare AirFloss Ultra is a quality all-rounder from a reliable household name. This cordless water flosser uses micro-droplet technology to send bursts of water and air around teeth and gums to remove plaque without the hassle of dental floss. You can buy this model in pink, black or white.

We like that the Sonicare AirFloss Ultra is rechargeable with a battery life of around 2 weeks. This means no mucking about with batteries. The Sonicare is easy to fill with an in-built reservoir at the back, though you'll need to top it up each time. It also has 3 different burst settings for a personalised clean. Replacement nozzles can be picked up from major retailers, and up to 97% of Philips Sonicare users saw improved gum health after use (source in references).

The Philips Sonicare AirFloss Ultra scores around 4 stars on, making it one of the highest-rated water flossers in its category. Most reviewers find it very effective, and one person says their teeth have 'never felt so clean.' It's similarly priced to other water flossers at around $190. Given it has a 2-year warranty, this could be a fair investment when weighed up against dentist's fees.

The not so good bits

Plastic tank

Some complain about the quality of the water reservoir, but if you take care of your water flosser, it should last its warranty.

Additional specs

If you're serious about water flossing, the Waterpik Ultra Professional is the best water flosser for teeth that need a little TLC. Waterpik has been in the oral healthcare business since the 1960s, and their water flossers are backed up by over 70 scientific studies. Waterpik flossers are clinically proven to be up to 50% more effective than string floss for improving gum health, and 3 times as effective for removing plaque around braces (source in references).

We rate the Waterpik Ultra Professional for its wide-ranging pressure system, with 10 settings from 10 to 100 psi. You'll get plenty of mileage out of this deluxe water flosser, with 3 classic jet tips and a toothbrush tip so you can brush while you floss. But it doesn't end there - this model stands out for its specialty tips, including a plaque seeker tip for implants, crowns and dental work, a pik pocket tip for periodontal pockets, and an orthodontic tip for cleaning braces. Did we mention there's also in-built tip storage?

The Waterpik Ultra Professional boasts one of the highest water tank capacities with a 600ml reservoir. This massive tank size means you won't have to refill as often, especially on higher pressure settings. It has a massage mode as well as a 1-minute timer to help ensure a thorough clean. While this model is a little bulkier than cordless models, we reckon its functionality more than makes up for its size.

The Waterpik Ultra Professional scores around 4 stars on Aussies say it's a 'joy to use,' with one person saying their teeth stay cleaner for longer. Another reckons it's ideal for orthodontic treatment as it helps prevent plaque build-up around their braces. While not everyone is happy with the quality of the plastic tank, overall it's a no-brainer for Aussies who need a specialty home water flosser.

The not so good bits


The 300ml tank may be a little cumbersome, but at least you won’t run out mid-floss.

Additional specs

If you're curious about water flossing but not ready to commit, the RENPHO Cordless Water Flosser is a wallet-friendly option at under $50. It has 4 different modes including soft, normal, pulse and DIY, with water pressure between 30 and 120 psi to cater to different oral care needs. The 300mL water tank is on the larger side for a cordless model, and means you won't have to stop for refills during heavy-duty flossing sessions. The water tank is also detachable to make life easier when it's time for a top-up.

I, Cosier writer Elese (hi!), have used other RENPHO products and I really rate the reliability of this brand. The RENPHO Cordless Water Flosser runs on rechargeable lithium batteries. It takes around 4 hours to charge, then it's good to go for around a month. This model comes with a USB charging cable and you can return it for a full refund within a year if you're not satisfied. For just under $50, it might not last beyond the 12-month mark, but it's a great beginner's water flosser at a budget price.

Others worth considering

Colgate Blast Cordless
Check price

The Colgate Blast Cordless Water Flosser is a no-nonsense machine for everyday flossing. It comes with 2 simple nozzles and a USB charging cord, offering an impressive 4 weeks' battery life on a full charge. It’s got a disappointingly small reservoir - it only has a 60-second water capacity. Expect to fill it before each use. The Colgate Blast has 3 pressure modes (gentle, regular, and pulse) for basic customisation. It retails at around $180, which we reckon is a little steep given its entry-level features.

Panasonic Ultrasonic
Check price

If you're looking for a well-designed water flosser with a solid sized reservoir, the Panasonic Ultrasonic Water Flosser is the way to go. It boasts 10 different pressure settings for sensitivities across the spectrum, and a 500ml water tank, all housed in one sleek station. The water tank is dishwasher-safe, too. And good news - this machine banishes flat battery woes by plugging in at the wall.

It's the small, simple touches that make the Panasonic Ultrasonic Water Flosser so ergonomically designed. The handle is magnetised so it sits neatly in its storage spot, and the retractable hose coils tidily at the base for a clutter-free countertop. It scores full marks from limited reviews on, and one Aussie says it's a great water flosser for braces and sensitive teeth. At just under $230, it's a little pricey, but with design like this it could well be worth your while.

Waterpik Cordless
Check price

If you're a beginner keen on a scientifically-backed water flosser, the Waterpik Cordless Plus is a great entry-level choice. Waterpik flossers are clinically proven to be more effective than string floss for improving gum health (source in references), so you know you're in good hands. This model comes with 4 different tips and a 2-year warranty, offering 2 basic pressure settings from 45 to 75 psi to blast through leftover bits.

The non-slip handle of the Waterpik Cordless Plus improves your grip despite its bulkier size, though the 210ml reservoir needs to be filled before each use. This could get annoying if you prefer the high-pressure setting. On the plus side, the Cordless Plus is rechargeable, so you won't have to keep buying new batteries.

The Waterpik Cordless Plus scores around 3.5 stars on, with most reviewers stoked with their flossers. Aussies like the pressure on this machine, saying it's easy to use despite its small water capacity. It's priced similarly to other models at around $170. If you're set on buying a Waterpik, this water flosser is a solid choice, with simple settings and straightforward design.

The bottom line

Remembering to floss is one thing, but actually doing it is another. The good news is there’s an easier way. Water flossers take the ‘ick’ out of your oral hygiene routine by providing a quicker, less hands-on way to floss. They get around braces and into tight spots with no dramas, and help you stick to your routine by making flossing straightforward. 

If you’re ready to invest in your oral hygiene, we like the Philips Sonicare AirFloss Ultra for compact quality from a reliable household name. Rated one of Australia’s best water flossers, it’s a simple way to take care of your teeth and gums. This model is rechargeable and lets you pick from 3 different modes.

Need a water flosser for braces, orthodontic, periodontic or similar dental work? The Waterpik Ultra Professional Water Flosser is a versatile water flosser with 10 specialty attachment heads for various oral hygiene needs. Its wide-ranging pressure runs between 10 and 100 psi, and it includes a massive 600mL water tank.

When you want an easier way to floss but your wallet’s on the lighter side, the RENPHO Cordless Water Flosser is the way forward. At just under $50, this little number one-ups pricier models with a 300mL water tank and a solid pressure range between 30 to 120 psi. It’s USB-rechargeable, too.

What you get if you spend more

If you've got a little more cash to splash, here are some features you can look forward to.


Most of the high-end machines we reviewed had much longer warranties than more basic machines. While the Thermomix has a 2-year warranty, the Magimix boasts a 30-year warranty. It's worth weighing this up, as a machine that lasts 30 years may be cheaper than several machines over the course of time.

Induction heating

Induction is an electromagnetic heating method that passes a current through a coil to create a magnetic field between the heat source and bowl or pot. This gives you much more precise control over temperature, as you're heating the bowl directly rather than the cooktop.

Fancy tech

Higher-end Thermomix alternatives usually come with higher-end tech. This can be as simple as automatic cooking functions or as complex as full-scale digital interfaces with WiFi connectivity. If you like your gadgets, you can expect high tech bells and whistles when buying a top end all-in-one.

Dual motors

While cheaper models have one motor to do it all, pricier models often have dual motors to share the tough graft. Generally one motor is for heating and the other is for mixing. 


Many pricier models justify their hefty price tags with accessories. These can be handy if you're a dedicated user. If you're not cooking with your all-in-one every day, you might find it frustrating having to store and sort through extra accessories.

Common questions

Which is better, manual or electric flossing?

Manual flossing is the cheapest way to floss, and is effective at cleaning between teeth. While it might be great for your pearly whites, single-use nylon floss may not be the most environmentally-friendly way to maintain good oral hygiene. Manual flossing can also be difficult if you have braces, dental bridges, or similar orthodontic or periodontal work, which is where electric flossing comes in.

Water and air flossers, sometimes called 'oral irrigators', are a great way to stay on top of your oral health routine. They're designed to blast plaque away from around teeth and gums, helping to prevent tartar in gum pockets too. Without a water flosser or a professional clean by a technician, it's difficult to get a whole-mouth clean like this at home. 

Electric flossers are pricier than manual flossers, but may save you money in long-term dental fees given they offer a more comprehensive clean. This means electric flossers are better for those with braces, implants, or similar orthodontic or periodontal work. They can also help you get into the habit of flossing regularly, as they're easier to use than standard dental floss.

Is water flossing messy?

Like using any new device, there's a small learning curve when figuring out how to use your water flosser. To use a water flosser with minimal mess, start on the lowest possible setting while leaning over your bathroom sink. With most models, water will splash out of your mouth and into the sink as you clean. 

How often should I use a water flosser?

The Australian Dental Association recommends flossing once a day, saying it should be 'an integral part of your dental health routine'.
