Quick start Troubleshooting Modes Good to know Care FAQs Specs

Mode: start on Sensitive or Soft · Water: lukewarm, never above 40°C · Session: about 2 min, then auto-off

Your first session

The trick to a mess-free session: lean over the sink with your lips loosely closed and let the water run straight out.

How to floss without spraying the mirror

Fill the tank and clip your nozzle on before you switch anything on.
Put the nozzle in your mouth first, pointed at your teeth - not the other way round.
Lean over the sink and part your lips just enough to let the water dribble out.
Now press the power button and work slowly along the gumline, letting the water fall into the basin.

1 Fill the tank. Open the tank cover, hold the flosser level, and fill it with lukewarm water - never hotter than 40°C. Close the cover firmly so it doesn't leak. You can also slide the whole tank off and fill it straight from the tap, then push it back on until it's snug with no gaps.

2 Fit your nozzle. Press and hold the release button on the neck, push the nozzle in until it clicks, and give it a gentle tug to check it's seated. There are four nozzles in the kit - the standard jet is the one to start with.

3 Choose a mode. Press the M button to cycle through the five modes. New to water flossing? Start on Sensitive or Soft - you can build up the pressure once your gums have settled in.

4 Get into position. Pop the nozzle in your mouth before you switch on, aimed at where your teeth meet your gums. Lean over the sink with your lips loosely closed, so the water runs straight out into the basin instead of down your chin.

5 Switch on and trace the gumline. Press the power button and guide the tip slowly along the gumline, pausing briefly between each tooth. Keep the jet perpendicular to your teeth and work round in order so you don't miss any gaps. Let the water fall out of your mouth as you go.

6 Empty and dry. It shuts off on its own after 2 minutes. When you're done, tip the leftover water out of the tank, press the power button for a second to clear the last of the water from the nozzle, then wipe it down and stand it up to air-dry.

Which mode should I use?

Five modes, all changed with the M button - press it to cycle through, even part-way through a session. Start gentle and work up as your gums get used to it.

SoftGentle pressure - the kindest setting for sensitive teeth and gums

SensitiveAlternating strength, made for first-timers and anyone easing in

NormalStandard pressure for everyday cleaning - handles most daily use

PulseA stronger pulsing flow that also gives the gums a gentle massage

Burst FireA focused point-to-point jet - handy around braces and tight spots

Power buttonStart, stop and switch off

M buttonChange mode (works while it's running)

The makers suggest first-time users stay on Sensitive for the first week, then move to the other modes once it all feels familiar.

The nozzles and how to swap them

Your kit comes with four nozzles, each shaped for a different job. They all clip into the same slot.

Standard jetYour everyday nozzle for all-round cleaning between the teeth and along the gumline

PeriodontalFor easing gently along and just beneath the gumline

OrthodonticFor cleaning around brackets and wires if you wear braces

Tongue cleanerFor freshening the tongue

To swap a nozzle: press and hold the release button on the neck, pull the old nozzle straight out, then push the new one in until it clicks. Give it a light tug to make sure it's seated.

Replace your nozzle every 6 months - sooner if the tip looks worn or the spray weakens. Nozzles are wearing parts, so they aren't covered by the warranty. The + Nozzle Set option keeps spares to hand.

Charging and battery

The flosser charges over USB-C. Lift the charging cover on the base, plug in the cable, and connect it to any standard USB power adapter - a 5V phone-style plug is fine, as one isn't always included.

Full charge4 to 5 hours

Between chargesup to 50 days of regular use

Battery gaugeThe battery cells on the screen show what's left - a steady, full symbol means it's done

When the battery symbol runs empty, it's time to top up. Charge it somewhere dry, not in the bathroom or anywhere humid.

Cleaning and care

After every session: tip the leftover water out of the tank, press the power button for a second to clear the last of the water from the nozzle, then wipe it down and stand it up to dry. Water left sitting inside is what leads to smells and grime.

Now and then: rinse the tank and nozzle under the tap - both come away for a proper clean. Wipe the body with a damp cloth rather than sitting it in water to soak.

Keep it simple: clean water or a mild washing-up liquid only - no harsh, gritty or abrasive cleaners, and nothing hotter than 50°C. Don't put mouthwash in the tank, as some kinds can corrode the parts. If you're away for a while, empty it fully and store it dry.

Is it right for me?

Water flossing is an easy thing to add to your routine, and it suits most people. A few pointers to keep it comfortable from day one:

Sensitive teeth or gumsStart on Soft or Sensitive and keep the pressure light - you can build up later

Braces, implants or crownsAll fine - use Burst Fire for a focused jet around brackets and tight spots

A little bleeding at firstQuite common in the first week or two while your gums get used to it, and it usually settles

Let the nozzle rest near the gumline rather than pressing it hard against your teeth or gums - a gentle touch does the work.

If you've had dental surgery in the last couple of months, or you have ongoing gum trouble, it's worth a quick word with your dentist before you start. This guide is here to help you use the device, not to replace their advice.

If something's off

Quick fixes and the fine print.

Something not right?

Nothing happens or it's stoppedLikely a flat battery, especially if it's new or unused for a while - charge it for at least 3 hours

Weak spray or no waterCheck the nozzle isn't blocked (swap it), and clear the suction inlet

Still weak after sitting idlePull the nozzle off and run it briefly to flush the hole, or fill the tank, hold it level and switch on to prime it

Runs flat quickly after chargingIt may not have charged long enough - give it a full 3 hours or more. If it keeps happening, the battery may be near the end of its life

Charge light won't come onReseat the cable at both ends. If it still won't charge, get in touch with us

Leaking from the tankThe tank hasn't clicked fully into place - push it home so there are no gaps

Your questions, answered

Will it hurt, and is a bit of bleeding normal?

It shouldn't hurt. Start on Soft or Sensitive, keep the pressure gentle, and let the nozzle sit near the gumline rather than pressing it in. A little bleeding in the first week or two is common as your gums get used to the routine, and it usually settles down. If it carries on beyond that, have a word with your dentist.

How do I stop it spraying all over the bathroom?

The trick is to put the nozzle in your mouth before you switch on, lean over the sink, and keep your lips loosely closed around it. Let the water dribble straight out into the basin as you go. Starting on a lower mode helps too while you get the hang of it.

Can I use it with braces, implants or crowns?

Yes to all three. Water flossing is a gentle way to clean around dental work. For braces, the Burst Fire mode gives a focused jet that gets around brackets and wires, and there's an orthodontic nozzle for the same job. Around implants and crowns, just keep the pressure moderate.

Warm or cold water - does it matter?

Lukewarm water is the most comfortable, especially if your teeth are sensitive to cold. Never fill it with water hotter than 40°C though - too hot can damage the tank and isn't kind on your gums.

Can I put mouthwash in the tank?

Best not to. Some mouthwashes can corrode the inside of the flosser over time, so stick to clean water in the tank. If you like using mouthwash, rinse with it separately after you've flossed.

How often should I replace the nozzle?

Around every 6 months, or sooner if the tip looks worn or the spray starts to weaken. Nozzles are wearing parts, so it's worth keeping a spare - the + Nozzle Set option comes with extras.

Does it replace brushing and normal flossing?

No - think of it as a helpful extra rather than a swap. It's good at flushing out the bits between teeth and along the gumline that a brush can miss, but you should still brush as usual. Many people use it just before or after brushing.

How long does a charge last, and how long does it take to charge?

A full charge lasts up to 50 days with regular use, so you won't be charging it often. When it does run low, a full top-up takes about 4 to 5 hours over USB-C. The battery cells on the screen show how much is left.

The spray has gone weak or stopped - what's wrong?

Usually one of three things: the nozzle is blocked (swap it for another), the suction inlet is blocked (give it a clean), or it's been sitting unused and needs priming. To prime it, fill the tank, hold the flosser level and switch it on, or pull the nozzle off and run it briefly to clear the hole.

Can I use it in the shower?

Yes - it's rated IPX7 waterproof, so getting it wet and rinsing it under the tap is no problem. The one thing to avoid is charging it in the bathroom or anywhere damp - do that somewhere dry.
