The Best Flosser in Australia

If string floss feels fiddly and you’re looking for a flosser you’ll use regularly, start with the Ordo Hydro Sonic+. It’s our top pick for its adjustable cordless design and 4.6 out of 5 owner rating from 57 JB Hi-Fi reviews: a useful starting point, though still a modest number of reviews.

For a flosser that stays beside the basin, we’d choose the Waterpik WP-660. If keeping the cost down matters more, the Oclean W10 is our budget recommendation with independent backing.

1. Best overall: Ordo Hydro Sonic+

If you want to add water flossing to your routine without making it complicated, the Ordo Hydro Sonic+ is where we’d start. Its Sensitive, Daily Clean and Power Clean settings give you a straightforward choice of pressure without a long menu to work through.

We like the pacing prompts for anyone who tends to spend too long on one part of their mouth and rush the rest. They give you a regular reminder to move on. USB-C charging also keeps the charging connection familiar.

Our take is that this is a sensible middle-ground buy. You spend more than you would on the Oclean or either COSLUS, but there’s an owner score to help judge the purchase. Don’t pay extra for it if you want fine pressure adjustments: the Waterpik below gives you ten settings.

Our verdict: Buy the Ordo if you want a straightforward cordless flosser with a useful owner rating behind it. Choose the Waterpik instead if finer pressure control matters more.

2. Best for braces and implants: Waterpik Ultra Professional WP-660

Cleaning around braces or implants can make an already fiddly routine harder. The Waterpik WP-660 earns our recommendation here because Waterpik lists specialist tips for orthodontics and dental prosthetics, alongside adjustable pressure.

Ten pressure settings let you make smaller adjustments rather than jumping between a few preset modes. Waterpik’s claimed reservoir runtime should also suit someone who wants a longer session before refilling.

Electric Teeth recommends it as Australia’s best benchtop option for its comfortable controls, generous reservoir and ten pressure settings.

The catch is the cost. It’s substantially dearer than the Ordo, so we’d reserve it for buyers who will use those specialist tips or finer adjustments. Amazon Australia was the sole stockist in our supplied retailer checks; check the warranty and returns terms before ordering.

Our verdict: Choose the WP-660 for its specialist tips and pressure control, particularly if you’re buying for braces or implants. For a portable routine, we’d spend less on a cordless pick.

3. Best for gentle cleaning: Philips Sonicare Power Flosser 3000

If comfort is what will decide whether you stick with water flossing, consider the Philips Power Flosser 3000. Good Housekeeping recommends it for gentle cleaning, which is why it earns this label.

Philips says its Pulse Wave technology guides you from tooth to tooth. That should appeal if you want help working steadily through the routine. Its ten intensity settings also give you room to adjust the pressure.

Electric Teeth highlights its quiet operation, adjustable pressure and helpful pacing.

This is the dearest flosser in the guide. Our take is that you should choose it specifically for the gentle-cleaning recommendation and pacing, rather than assume spending more guarantees a better result. Our stock checks list Amazon Australia alone for this model, so review the warranty and returns terms before buying.

Our verdict: The Philips is worth considering when gentle cleaning and guided pacing are your priorities. If you mainly want adjustable pressure, the cheaper Waterpik is our stronger value call.

4. Best budget pick with independent backing: Oclean W10

You don’t need to start with an expensive flossing machine to get useful controls. The Oclean W10 costs less than the Ordo and includes an on-demand mode that Oclean says gives beginners more control over the water flow.

Live Science recommends it as its budget pick for powerful cleaning, easy refilling and useful features.

Our take is that this is the sensible way to spend less while retaining an independent recommendation. The removable tank should make access for cleaning easier, but its capacity is smaller than the Ordo’s 260 mL tank. Choose it for the controls and price, rather than for a larger reservoir.

Amazon Australia is the only retailer recorded as stocking it in our checks. Confirm the warranty and returns arrangements on the listing before you commit.

Our verdict: The W10 is our budget recommendation if you want independent backing without paying for the Ordo. Its on-demand mode makes it especially worth considering for a first water flosser.

5. Best portable water flosser: Colgate Blast

If you want to keep the same routine when you’re away, the Colgate Blast is our portable choice. Colgate’s compact cordless design and claimed battery life of more than three weeks make it a sensible travel candidate.

Finder recommends it as its best cordless option for portability, adjustable pressure and long battery life. It was also ranked number 21 in Power Flossers & Oral Irrigators on Amazon Australia when we checked.

Three modes keep the decision simple, though they leave less room to experiment than the Oclean’s five. We’d choose the Blast for taking away rather than for extensive customisation. Amazon Australia was the only stockist shown in our retailer data; check the warranty and return conditions before placing your order.

Our verdict: Choose the Colgate Blast if portability is the deciding factor. The Oclean is our preference if you’d rather have more modes for a similar outlay.

6. Budget pick for straightforward controls: COSLUS C20

If you want to try water flossing without spending much or sorting through lots of settings, the COSLUS C20 is worth a look. Its three pressure modes keep the controls straightforward.

It’s here because it sells well on Amazon Australia: it was ranked number 1 in Power Flossers & Oral Irrigators on Amazon Australia when we checked. We found no independent owner rating at the retailers we check. That sales position doesn’t tell us how satisfied buyers are.

Our take is that the detachable tank is a useful feature at this price, but the cheaper C30 below offers more pressure adjustment. Pick this one if you prefer fewer choices. Only Amazon Australia appears as a stockist in our data, so check its warranty and returns terms before buying.

Our verdict: Buy the C20 if you want a low-cost flosser with simple controls. We’d choose the C30 if adjusting the pressure matters more than keeping the settings basic.

7. Lowest-priced pick: COSLUS C30

When keeping the initial spend down comes first, the COSLUS C30 is the cheapest pick here. It still gives you a DIY mode, so a small budget doesn’t mean being restricted to a few fixed settings.

We included it because it sells well on Amazon Australia: it was ranked number 3 in Power Flossers & Oral Irrigators on Amazon Australia when we checked. We found no independent owner rating at the retailers we check.

The memory function should save you selecting your preferred setting each time. That’s useful, but our take is that this remains a purchase driven by price and listed features. We’d spend more on the Oclean if an independent recommendation would make you more comfortable buying.

Our retailer data lists Amazon Australia as its sole stockist. Check the warranty and returns terms, particularly if you’re choosing it as your first portable oral irrigator.

Our verdict: Choose the C30 when the lowest price is your priority and you’re comfortable buying on specifications and sales rank. The Oclean is our preferred budget buy if you want independent backing.

How we chose

These water flosser reviews are based on owner ratings and review counts, independent recommendations, maker specifications, and price and stock checks. Models with a solid owner rating or an independent recommendation come before those selected on Amazon sales rank alone. All seven were in stock at Amazon Australia when checked; the ranking also considers who each model suits and what you get for the money.

Ordo has the only owner rating in the supplied retailer data; we found no independent owner ratings for the other six at the retailers we check. Stockist notes describe those checks, not every Australian retailer.

Water flosser buying guide

If you’ll take it away, start with a cordless design

A portable water flosser makes sense if you want to pack it for trips or put it away between uses. Look at the charging method and what’s included before buying. A long battery-life claim is less useful if you arrive without the charger you need.

For a flosser that will stay beside the basin, decide how much space you’re willing to give it. Check the listing’s dimensions against your bathroom before ordering a benchtop model.

If pressure worries you, look for adjustment

Don’t choose a water flosser on its maximum pressure alone. Consider whether you want a few simple modes or smaller adjustments between settings. The right controls are the ones you’ll feel comfortable using.

A setting called Gentle or Sensitive is a maker’s description, not a promise that it will suit everyone.

If refilling would put you off, check the tank

Tank capacity and stated runtime are different things. Use the maker’s runtime where one is supplied rather than converting millilitres into minutes yourself.

Also consider how you’ll fill, empty and clean the reservoir. A removable tank is worth looking for if access matters more to you than extra modes.

If you’re buying for dental work, check the tips

Look for an explicit listing of the dental work and tips the product supports. Don’t assume every included nozzle is intended for braces or implants.

Check the availability and cost of replacement tips before committing, especially if several people will use the same device.

If the price looks unusually low, check the whole purchase

Confirm whether the charging adapter is included, what warranty applies and how returns work. Where the guide has no owner rating, weigh the listed features and purchase terms rather than treating a sales rank as proof of quality.

Keep health promises separate from the buying decision

A product listing’s claims about cavities, gum disease or replacing string floss shouldn’t decide the purchase. Follow your dental professional’s advice about your cleaning routine and any particular dental concerns.
