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.

Good unit, easy to use and seems effective!
The device is very easy to operate. I fill the reservoir twice. Once for the bottoms and once for the tops. I have been using it on the children’s mode to get my gums accustomed to the process. It’s very easy to change modes. I remove the wand from the unit after I use it. One of the reviews I had read said someone had knocked his unit off the counter and the wand had broken off when It fell. The unit operates quietly and is easy to fill. I dry it off after use and leave the fill plug open and separate the unit to hasten the drying process. I am pleased with the product. It was an easy process to register the unit for the 2yr guarantee. The unit was very easy to charge.

Love This Water Pick!
Love this water pick! Easy to use and very portable. I find it is better than flossing and much more efficient (very powerful spray). It took me a few days to get use to using it and not spraying water everywhere but it was well worth the effort. I highly recommend this product. So far, after five weeks of use, no problems.

Very good but imperfect
This is a very nice water flosser. The extra-wide spray, both with the normal and especially the “dual flow” attachment, is more gentle and seems to do a better job than other water flossers I’ve tried. The reason for four rather than five stars is that the charging cord uses a narrow two-prong connector instead of a USB-C connector. Another minor issue that I’ll mention without changing the stars is that it is a little more difficult to fill with water than other flossers I’ve tried.

Great Portable Water Flosser: Powerful and Travel-Friendly
I’ve been using the COSLUS Water Dental Flosser for a few weeks now, and I’m really impressed with its performance. The water pressure is strong enough to thoroughly clean between my teeth and along the gum line, yet gentle when using the lower settings. My mouth feels noticeably cleaner after each use compared to regular string floss.The 300ML water tank is a great size; it holds enough water for a full cleaning without needing constant refills. I also love that it’s cordless and rechargeable, making it perfect for travel or small bathrooms. The battery life is excellent; one charge lasts me well over a week of daily use.Another big plus is the IPX7 waterproof design. I can safely use it in the shower without worrying about water damage. The unit feels sturdy, well-built, and easy to handle.Overall, this is a great value for the price. If you’re looking for an effective, portable, and easy-to-use water flosser, I highly recommend.

Great value, works well.
I ended up buying one of this for every member of my family when they went on sale. Great battery life, good sized resevoir, the attachments are easy to install, and it does a great job cleaning. It also survived two airplane trips in my checked bags just fine. The regular strength is strong so start with the soft setting.

A great dental flosser
My dentist recommended that I buy a dental flosser so, as I usually do, I read the reviews on the ones labeled best and decided on this one. I love it for its compactness and the convenience of being able to take it on trips. It is easy to use and has a number of settings and it is rechargeable. The only down side is that it doesn’t come with a charging adapter, but any 5V adapter will do.

Handy and effective portable dental flosser!
This water dental flosser is great for cleaning between teeth and along the gumline, especially when I’m on the go. The portable design makes it easy to use while traveling and it feels gentle yet effective. Battery lasts well and it’s simple to refill and clean. Not quite as powerful as a full-size unit, but excellent for daily touch-ups and travel!
Yasmine –
Very durable
I have been using this product for months now, on daily basis, 3 times a day. It works like magic. The charge last for weeks and it doesn’t leak or whatsoever.It is not loud but not very quiet as well.Very comfortable to the sensitive gum or teeth hence it has levels for its tensity.It is worth the month and works great for those who wear braces because it cleans the teeth pretty well.

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.
