- Insert the nozzle into the top of the device until it clicks.

- Press the power button and glide the tip along your gumline and between teeth.
- After use, empty the remaining water and collapse the tank for storage.
What Our UK Customers Say
I've tried the water flosser from Boots before, but this is so much better for travel. It fits perfectly in my handbag for post-lunch cleaning at the office.
As someone with braces, this is a lifesaver. It gets into the gaps that string floss just can't reach. Delivery was next day too!
I frequently recommend water flossers to my patients with bridges. The Synhope provides the necessary pressure for clinical efficacy in a very clever, portable form factor.
Great little device. The tank is a bit small so I have to refill it twice for a full clean, but that's the trade-off for it being so compact.
Better than the Panasonic water flosser I had previously. The pressure is stronger and the telescopic design is genius for my gym bag.
Solid build quality. It took a few tries to get the hang of the telescopic mechanism, but now it's part of my daily routine.

Redefining Interdental Care for the Modern Briton
At Synhope, we believe that maintaining a healthy smile shouldn't be restricted by your location. Founded with the mission to make professional-grade gum health accessible to everyone, we identified a significant gap in the UK market: the need for a water flosser that is as powerful as a countertop unit but as portable as a smartphone.
Our journey began by redesigning the traditional water flosser from the ground up. By introducing the innovative telescopic water tank, we've created a device that fits easily into a gym bag, handbag, or carry-on luggage. We understand the unique challenges faced by those with braces, bridges, and crowns, which is why our technology focuses on precision and comfort above all else.
Based in the UK, we are committed to quality and safety. Every Synhope product undergoes rigorous testing to meet UKCA and CE standards, ensuring that our customers receive a reliable, waterproof, and effective tool for their daily routine. We aren't just selling a gadget; we're providing the confidence of a dentist-clean feel, every single day.
