This portable WaterPik really gets everything off of and in between your teeth. I've been using it daily for about a month and am impressed with it's powerful ability to remove everything my floss or toothbrush miss. The pressure isn't painful at all. There are two settings, High and Low. When used with warm water, it's a comfortable yet very effective cleaning tool.
I would recommend this to a friend!

Very impressive cordless waterpik
on June 14, 2026
Posted by: KeeganG
[This review was collected as part of a promotion.] I have had a waterpik once before that had a large reservoir and was constantly plugged into a wall outlet. I was expecting the cordless one to be underpowered and to have to constantly be charged. However, I charged it the first day it arrived, and have used it everyday since sometimes multiple times per day and it still has yet to need a recharge (about 45 days of use on one charge). You can see from the pictures I uploaded comes with several attachments and a cord for charging. It does not however come with a power block which is a common thing now for electronics, that is to include a cord but not a power block, and I find it rather annoying.
The waterpik is sufficiently powered if you turn it on and it starts going and then you hit the power button once more. It goes into high power mode that tends to work better in certain situations. In general, I think it works really well, however I never feel like it doesn't do quite as good a job as flossing in terms of getting stuff OFF of my teeth. It gets out from between my teeth but not necessarily off my teeth. Regardless, I'm very pleasantly surprised and I still haven't charged it and it's still running great. You do have to be careful not to get water everywhere, you basically have to have your mouth over the sink and looking down or else it splashes and gets everywhere. That being said, the instructions actually go over this and so if you read the instructions you'll find that out. Build quality is great and feels like it will last a long time. I'd give it 4.5 stars if I could.

The 2 pressure settings have been working well.
Tips on how to be less messy would be helpful but I am enjoying the experience and the results of how it is working.
I would recommend this to a friend!

My dentist will be happy!

[This review was collected as part of a promotion.] I absolutely love this water flosser! My dentist always tells me at my checkups that I need to do a better job cleaning and flossing my back teeth. It’s kind of hard to reach back there and clean thoroughly, but not with this waterpik. I love that it has 2 speeds. I can use the lower speed on my more sensitive teeth and the high speed to turbo blast where I need to. This is a must have for cleaner teeth!

Convenient if form and function

[This review was collected as part of a promotion.] My dentist recommended that I get a water flosser. I put it off for a long time. My home is older and doesn't have an outlet in my bathroom. This cordless Waterpik solves that problem, and it does it beautifully. Its small profile takes up less room on the counter than the old water flosser I remember my parents having in the 90s and it's light weight enough to use with a full reservoir. I would definitely recommend it.
