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.

Great Water Dental Flosser
This Coslus water dental flosser works very well. It comes with 3 different types of tips and a tongue scraper. The flosser is very easy to use and directions (if needed) are very simple to follow. This flosser works so much better than traditional dental floss.

Performance for price
Nice product, does the job but very loud.

Great overall product!
Great product! Have been using this for years now. Have one for me, one for my wife, my niece wanted one so got her one too.Could be a bit more flexible in terms of intensity, but the different modes are nice and I like the more intense mode. Helps keep gums clean and healthy, gets stuff from between teeth easily, and not too noisy.Reservoir is the right size for one person to do both top and bottom, inside and out.Battery life is also very good. Seems like months between charges, although I haven’t actually measured it.

The best tooth/gum cleaner ever
Love love love it I couldn’t believe how well this water pick works. I was about to buy one from the dentist cause she recommended it to me but after hearing that it was $115 I was like well I don’t need it that bad. Anyways I look on Amazon and I got this bad boy for like $25 and it works really good. If you want the cleanest gums and teeth you’ve ever had (aside for when you get a cleaning at the dentist) buy one of these affordable water picks

Easy to use and works as expected
I like it. Got it as a Christmas present for my husband and myself. I thought it was going to be messy but it worked nicely and didn’t splatter water everywhere! I still think I need to floss still from time to time , but think it helps getting into the areas that are hard to access.

It’s a great product and very useful for the whole family.
The Coslus Water Dental Flosser Teeth Pick is great to have at home. Even my 11-year-old son uses it, and it’s very easy for him to handle. It’s especially helpful for kids, since they don’t always brush perfectly — this flosser removes anything left behind and keeps their teeth much cleaner.It’s simple to get used to, and you can really see the benefits in your teeth and gums after using it regularly. It also comes with different tips, which is very convenient. One of the things I love most is the battery life — I’ve only had to charge it once in almost a year, which is amazing.

Buy the extended warranty
It works *very* well, but battery dies after a few months.I really loved the tank size and the power of the water pump, but after 4 months, the battery would only hold enough charge to clean half of my mouth before dying, rendering the product itself unusable.It started out with great battery life, only needing to recharge once a week at most, but the battery slowly but steadily started losing endurance. The last few weeks of using it, I had to charge it daily just to run long enough to empty the tank. The final few days, it only lasted long enough to get halfway through the tank before dying. I stopped using it at that point and bought a different, cheaper one. I’ve been using that one for the past year and a half, and it’s just now getting to where I need to charge it every 4-5 days.I would be hesitant to recommend it, *unless* you purchase the longest offered extended protection plan for a few dollars, with the expectation of regularly filing claims with it. In that case, I would highly recommend it! It’s a great little machine, aside from a poor quality battery that is not replaceable. It would be better if it charged from a standard USB C connection, but this company isn’t unique in requiring a proprietary connector from my experience.

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.
