Brushing stops at the surface.
A brush cleans what its bristles can touch. That leaves the tight contacts between teeth and the narrow pocket just under the gumline — which happens to be exactly where food and plaque collect.
String floss reaches those places, if you use it correctly, on every tooth, every day. Almost nobody does. A pulsed water jet at 120 PSI gets there in about a minute, and it doesn't depend on your technique.
How it works
1. Fill the 300 ml tank. Room-temperature water, or half water half mouthwash if you prefer. That's roughly a minute of continuous run time — enough for a full pass without stopping to refill.
2. Trace the gumline. Lean over the sink, close your lips loosely around the nozzle and follow the gumline tooth by tooth, pausing at each gap. Start on soft, work up to high once your gums settle in.
3. The water does the reaching. The V-shaped nozzle drives 1,600 pulses a minute into the contacts between teeth and just under the gumline, and carries what's trapped there out with it.
One minute vs. the old way
String floss works — if you thread it correctly, on every tooth, every night. The problem was never the floss. It was the technique, and the fact that almost nobody keeps it up.

Why we built this
Everyone gets told to floss. Almost nobody keeps it up — and not out of laziness. String floss is fiddly, it stings when your gums are already irritated, and around braces or a bridge it borders on impossible.
A water flosser removes the technique problem entirely. You point it at the gumline, work around your mouth once, and you're done in about a minute. Nothing to thread, nothing to snap, nothing to get right.
We sell one thing and we're specific about what it does. It flushes food and plaque out of the places a brush can't reach. It doesn't whiten, it doesn't sterilise, and it doesn't replace brushing — it's the step in between. Five nozzles in the box, no proprietary refills to buy, and none of the markup the big cordless names charge for the same job.
Everything you need to know
Does this replace flossing?
For most people it does the same job, more consistently — it flushes the gaps between teeth and along the gumline. What it doesn't do is scrape the flat side of a tooth the way string floss does. If your dentist has told you to floss for a specific reason, use this alongside, not instead, and ask them first.
It never replaces brushing. It's the step in between.
My gums bleed. Will this hurt?
Start on soft mode and stay there for the first week. Some bleeding in the first few days is common when gums haven't been cleaned along that line before, and it usually settles. If it's still happening after two weeks, that's worth a conversation with your dentist rather than more pressure.
Can I use it with braces?
Yes — this is where a water flosser earns its place. The orthodontic nozzle is shaped to get around brackets and under wires, which is the part of flossing with braces that most people quietly give up on. Same goes for bridges, implants and permanent retainers.
Which nozzle should I use?
Standard — daily use, everyone starts here.
Plaque — a tighter jet for stubborn build-up on specific teeth.
Orthodontic — braces, bridges and permanent retainers.
Periodontal — a soft tip for flushing deeper gum pockets, gently.
Tongue cleaner — the back of the tongue, which is where most bad breath actually starts.
Nozzles twist off and pull out. All five are in the box.
What are the four modes?
Soft — gentle, for sensitive gums and your first week.
Standard — everyday cleaning.
High — the full 120 PSI for stubborn spots.
Pulse — an alternating rhythm that massages the gumline while it cleans.
Hold the power button for two seconds to switch on, then tap the mode button to cycle through.
How long does the battery last?
Three hours on the USB-C cable gives up to 70 days of normal use — roughly once a day, one tank at a time. It's IPX7 waterproof, so it can live in the shower or go in a wash bag without ceremony.
The cable is included. A plug isn't — any USB wall charger or laptop port works.
Anything I should know before the first use?
Lean over the sink and start with the nozzle already in your mouth — at 120 PSI, switching it on early sprays the mirror. Keep your lips loosely closed and let the water run out.
Use room-temperature water. Don't direct the jet under your tongue or into your ears or nose, and don't use it if you have an open wound in your mouth. Children under six should be supervised.
After each use, empty the tank, rinse it and let both the tank and the handle air dry.
Can I put mouthwash in the tank?
You can — dilute it roughly half and half with water. Run a tank of plain water through afterwards so nothing dries inside the pump. Neat mouthwash left sitting in the reservoir is how these things get sticky.
