Previously, I had the Waterpik sidekick for travel, and I was very satisfied by the quality and the effect it had on my teeth, so I decided to purchase The Waterpik ION Professional cordless water flosser as a more permanent addition to my bathroom. It has truly impressed me with its exceptional performance and notable benefits for gum health. I used to go get my teeth cleaned every 6 months, and now I can go every year and the dentist compliments me each time. I use it after each meal, 3 times a day when I can, and my teeth and gums feel remarkably clean and refreshed after each use. I use pressure setting 9 out of 10. I have to recharge it every 10 days. Multiple different nozzles are included so you can try them out, but I only use the standard nozzle. The size is just perfect: not too big so it fits into tight bathroom areas, and not too small either: the water container is enough for one person thoroughly using it. The cordless feature adds convenience and saves time each morning. I like the magnetic handle cradle. On the Waterpik Sidekick that didn;t have this feature, I had to store the handle inside the water container, and it was really not as conveniant. I don't live in the USA, so I'm happy you can recharge it on 220 V. You need your own charger though, it is not included in the box. I use a phone charger that I can plug the included USB power cord into. The plug on the unit itself is not standard so you had better not misplace the power cord! I highly recommend the Waterpik ION Professional for anyone looking to enhance their oral hygiene routine. Read more

Got this because my old one's tubing broke. A Wire Cutter fave. It's great! Only needs to be charged every few weeks and nice not to have it plugged in all the time. Read more

I bought this in December of 2023. As is typical, the unit stops charging after several months. I had it replaced under warranty and the new unit is doing the same thing. I'm now 2 years out from the original purchase. I keep it in the shower so I can't entirely blame the product, but with the second device, I've kept the charge port covered with cellophane and a rubber band. The issue is oxidation on the charging contacts. As long as it doesn't get rusty like my first one got, you can easily get it to charge by using a q-tip with white vinegar. It's amazing that just a few second treatment does the job. But you have to do it every time. You can actually tell there's an impending problem when during use it starts to flash like it does when it's ready to charge but then shuts off before completing the last use. When it's newer, you certainly have enough power left at that point to make it through the last clean. Anyway, I give it still a four star because it is such a good flosser otherwise. There's no other battery powered flosser with this kind of power, water capacity and portability. What's weird? Is that Waterpik surely knows about this issue and hasn't done anything about it. Wireless charging or even just a water tight cap over the charging port would probably solve the problem. Read more

It worked just fine. I noticed a dramatic change in the color of my teeth, even though I got it primarily for flossing. The problem is, it stopped working a couple of days ago out of the blue. I purchased it in July, my return expired in August and it cost 99.00 I had to come back and change my review from 3 to 5 stars. It works!!! It was the charging port. It’s constantly exposed to water so some red substance like erosion or rust was blocking the charge. I cleaned it and now it’s working just fine. I’m glad because I was considering getting my teeth whitened to match my implants. I bought this device because my dentist recommended it for cleaning the implants. I also used it on my natural teeth by mixing a little hydrogen peroxide in the water. My teeth whitened and now I don’t need the dentist to do it. This was a good purchase so thumbs up and highly recommended. 👍🏾👍🏾 Read more

After only 9 months, this thing will not turn on anymore. It is under warranty from Waterpik, but their customer service is absolutely a nightmare to deal with. Don't waste your time. They are slow to respond and each email just brings up a new line of questioning. Most companies would have sent a shipping label to send the unit in for warranty by now. I have been emailing back and forth for a month now with no resolution. They are doing everything they can to not fix or replace this machine. Some excerpts from those emails are below: 1. "Thank you for reaching out to the Waterpik Product Support Team. Since we know your flosser motor is not turning on, I’d like you to try the following steps listed below. What could be happening here is the Ground Fault Interrupter (GFI) in the bathroom is interfering with the power going to the unit. In order to test this, I would like for you to take the unit into another room, such as a living room or bedroom, where there is no running water. Try plugging the unit into an outlet in one of those rooms and turn on the flosser to see if the motor turns on. If it does, then purchasing a Single Outlet Surge Protector for the bathroom outlet should resolve this issue in the future. Additionally, we also recommend deep cleaning your unit with a 50/50 solution of warm water and distilled white vinegar. Afterwards, we recommend continuing to clean with a 2:1 ratio of warm water and distilled white vinegar every 1-3 months. If the step above is unsuccessful, then please let me know so we can look into additional steps. " 2. "Thank you for reaching out to the Waterpik Product Support Team. I’m sorry your ION isn’t working properly, but I’m happy to help you look into this today. In order to better assist you I’d like to ask a few questions. I look forward to helping you resolve this issue. How often is this machine used? Do the LED lights illuminate? If they do, please plug the unit into the charger and describe the light pattern. Does the machine’s motor turn on? If there is no motor sound, did it stop during use? How often do you charge the machine? How long do you leave it on the charger? Do you see any discoloration on the charging contacts? Has the machine ever been used in a shower? Do you store water in the machine between uses? What is the color of your machine? Once I have the information above I will have a better idea on how to assist you." 3. "Thank you for reaching out to the Waterpik Product Support Team. I’m sorry to hear that your machine isn’t working properly, but I’d be happy to help you look into this issue. Based on your answers, it sounds like the machine may not be making a proper connection to the charger. Sometimes moisture can affect this connection. We recommend ensuring this connection is always kept dry when you are connecting the charger. Ensure your charging cord is connected on a flat surface. Please note a properly charging machine’s LED indicator will glow as it charges. Improper charging may have a rapid, or inconsistent blink. Please use the following steps to try to return function to your machine. Unplug the charging cord from the outlet and remove it from the machine. Dip a cotton swab or clean cloth in white vinegar. Using the above, please gently clean both the connection on the machine itself, and the connection ports on the charger thoroughly. After cleaning these connections, please allow these connections to dry completely and re-connect the charger. The LED light should slowly fade from bright to dim while charging properly. After the charger ports on both components are cleaned and dry, please charge the machine for a full 4-6 hours. If the above steps are unsuccessful, then please let me know. If possible, please attach a short video of the machine’s lights while on the charger and when trying to activate the flosser motor. Once I have a little more information, I’ll have a better idea of where to go from here. I look forward to hearing back from you. Read more
