Customer Reviews for Waterpik - Cordless Plus Water Flosser - White

Verified Purchase:Yes
I really love the portable waterpik - it's easy to fill and use and then be done. Love that the charge lasts for a month also! I haven't plugged mine in since i got it almost a month ago - It lasts a really long time! I travel often and the compact design makes it easy to travel with also. Definitely recommend!
I would recommend this to a friend!

I have some concerns. First, it takes at least 3 refills to get my entire mouth done. Second, the water adds to the weight of the water pik. Third, my thumbs have a little arthritis, so this is not easy to maneuver, turn, change speed, etc. Fourth, the place where the charger plug goes needs to have some kind of cover so water doesn't get in. It is impossible to keep this appliance dry while using it. I'm also not happy that the plug/box, whatever you're calling it, was not included. Sure, I could charge it by plugging it into my computer, but why do I want my oral hygiene stuff sitting on my desk when I have a perfectly good electric outlet in the bathroom?

It was disappointing that the unit did not come with the USB charger that is needed to xharge the unit. It calls for a specific charger, thatbi don't have. So im using one that is close. The charger indicator light constantly blinks, and is not addressed in the instructions. The water reservoir should be a bit larger so you don't have refill during a floss.

Hello Mark- Thank you for your feedback. We apologize for any inconvenience caused by the absence of a wall charger. To help reduce electronic waste, our product is designed with a USB cable only. We understand your concern and will share this feedback with our product team for consideration.
Regarding the charging indicator light, we apologize for any confusion. This model does not have a traditional charge light indicator. The blinking light is designed to prevent overcharging and operates on a 20-hour timer. It will flash whenever it's plugged in. If the light goes off, it serves as a reminder to unplug the device. For optimal charging, we recommend charging the unit every 7 uses for about 8-10 hours.
We also appreciate your feedback about the water reservoir size. We'll pass this along to our design team as we continually work to improve our products. If you have any more questions or need further assistance, please don't hesitate to contact us at 1-800-525-2774 or smreviews@waterpik.com.

Very easy to use once I got the angle correct. Battery lasts about a week. Charges quickly.

Disappointment
on January 30, 2026
Posted by: Bing
I was disappointed that the WP-400 I bought provides a very weak stream of water, which often stops completely depending on how I am moving the unit, and it is rather difficult to maneuver during use. I would not say the product is defective, but compared to other Waterpiks I have owned, this has been less than satisfactory.
No, I would not recommend this to a friend.

I had one for many years and really liked it before it gave out on me. I then purchased this one because it is quite similar. It is evident when I use it that just brushing would not get all of those tiny particles of food out.

Does not hold enough water. Must be held upright or at a slight angle to function which makes it difficult to use in a sink. Otherwise, the power and attachments are ok.

Hello Wanda M - We're sorry you are not fully satisfied. While the pressure in the WP-450 model isn't as high as in our countertop versions, it's designed to be effective. This model is compact for travel and small spaces, so some users may need to refill the reservoir more frequently. If refilling is inconvenient, we recommend trying a countertop model. We offer a 30-day money-back guarantee if you're not satisfied. For more information, please email us at smreviews@waterpik.com or call 1-800-525-2774.
