Why does the COSLUS water dental flosser only have three modes?
Developed over 3 years through extensive user testing, this flosser offers 3 simplified modes for ultimate ease of use. Suitable for all ages, from teens to seniors, it is built to deliver a premium lifespan of 3 years.
What is the intensity of the water pressure? Which mode should I choose?
This flosser features three pressure modes: high (Clean), medium (Message), and low (Soft). First-time users should start with the gentle Soft mode. Any initial gum bleeding is normal and should subside quickly as gums adapt.
Do you need to add water a lot during use?
No, this water tank has an upgraded, super-large capacity of 300ml, which is enough for a 2-minute cleaning session.
Where can you get replacement tips?
Nozzle Replacement: For best results, replace every 3 months. Find accessories on our product page, website, and COSLUS store.
Does the package include the charging adapter?
The adapter is not included to avoid waste. You can charge it using any standard 5V adapter (like one from a phone or tablet). If needed, you can purchase a compatible adapter from COSLUS.

Powerful flosser with simple setup and great results
After using the COSLUS Water Dental Flosser for a few days, I can already tell itâs a great addition to my routine. The water pressure is strong enough to make a real difference in cleaning between teeth, and the overall setup is simple once you read the instructions.The unit feels sturdy and well-designed, and I appreciate that it comes with clear guidance and multiple nozzles so both my husband and I can use our own attachments. Itâs surprisingly easy to fill and clean, and the charge lasts through several uses without needing a recharge.If youâre new to water flossers, I definitely recommend reading the instructions firstâit takes a moment to get used to the pressure and positioning, but once you do, itâs straightforward and effective.Quick Highlights:⢠Strong, consistent water pressure⢠Easy to fill and operate⢠Clear instructions and good accessoriesIdeal for anyone looking for a reliable at-home flosser that feels professional yet easy to use.

Extremely powerful and effective!
My dentist recommend me this after noticing that my gums had seen better days, when I recived the product I was pleasantly surprised at how compact it was and the plethora of attachments for most cleaning jobs! Its fairly easy to use with just a few buttons controlling the power and mode. Its important to note that proper technique is needed since this does have to potential to damage your gums. With the flosser being recharged there’s no need for batteries and its compactness make it easy to take on trips. Ive personally seen an overall improvement to my gums health aswell as much less plague on my teeth. I recommend this to pretty much anyone as it makes it so you dont have to buy dental floss!

Works alright
This dental flosser device works alright for me. Overall is quite decent, lightweight, easy to use and water pressure. Though I feel that the design could’ve been a bit better with the handle and grip of it and the size to be a bit more ergonomic or compact. Would be even better if the water pressure can be more adjusted since it’s a bit rough and harsh for me.

Great water pick. Great price
I am addicted to using a water pick. My last one stop charging so I had to immediately replace. This one is great. Came with quite a few pieces and was already charged when I got it. It has a much bigger water tank than my last one. The speed is variable, so you can choose your own strength. Easy to use and works well

Saved my gums!
Amen and amen. After having a filling done, there has been a gap in my teeth that traps food that even floss cannot remove and causes a lot of discomfort. THIS RIGHT HERE has saved my oral health. The water is powerful enough to dislodge tightly packed debris. Itâs easy to use and lightweight. Itâs a little messy, but it gets the job done.

Works well..until the battery develops performance anxiety
I’m legitimately bummed about this one. This water pick works very well. I’ve used it religiously. In fact, I bought the exact same model for my son. It’s very effective. Unfortunately, the battery is…not.After about a year, the battery was noticably weaker, and continued to decline. For several months, I’ve been dealing with the fact that it needs to be charged every other day, which means I was getting about 6 minutes out of a full battery charge. Last night, I had to toss it,. because it won’t be even hold enough charge to get through ONE use. I definitely didn’t overcharge it. I never stored it on the charger, and always let the battery run out before charging. There were a handful of times that it charged overnight, but never longer than that. And, honestly, in 2025 that shouldn’t matter that much. Modern batteries are are perfectly capable of handling an overnight charge, on the regular.Maybe 2 years is all the life you should expect out of a dental appliance that use daily. If the battery has just started going bad, I’d probably agree. But this started a year ago.

I always find it difficult to use the string type of Dental Flosser as my teeth are too close together and it bleeds when I forced the string between the teeth. With a Water Dental Flosser, I don’t have any problem as the water jet is strong enough to flush in between the teeth. I need to do this as my gums are quite sensitive and get inflamed if food are stuck in between the teeth which toothbrushes cannot get it out.
