Super Clean Feeling - So Effective

Maggie88 August 13, 2022

[This review was collected as part of a promotion.] This power flosser leaves your mouth feeling super clean and fresh. I was not sure how it would work but it is so effective. The perfect addition to my oral cleaning routine. The cordless style makes it so easy to use and clean. It is easy to fill and holds enough water for use . Holds a charge for a long time. I can feel a difference in how clean my mouth feels. It comes with everything you need. The instructions are good - it is really intuitive to set up and use. You have a lot of choices for strength and mode. I like the deep cleaning mid level strength. Works on all those hard to reach places. So happy.

Leaves my teeth feeling clean!

M2015 July 5, 2022

[This review was collected as part of a promotion.] This Philips brand Cordless Power Flosser 3000 works great! It's easy to use and I like that it comes with two attachable heads for ultimate flossing. The buttons are easy to use and I also like the power options (how hard you want the water to spray). The attachments fit nicely into my small mouth and didn't give me any discomfort. It's powerful and it leaves my teeth feeling clean!

Love that it cordless

Sbailey1959 July 6, 2022

[This review was collected as part of a promotion.] My absolute favorite part of this is that it is cordless and easy to maneuver without getting tangled in a cord. It's so easy to use, and does a real good job cleaning my teeth! It comes with 2 nozzles, one is pretty much straight forward, normal nozzle. The second is quad, it sends water in 4 directions cleaning quicker. It took a little bit to get used to it, but I love it!

Love it!

Jamieberg1451 July 24, 2022

[This review was collected as part of a promotion.] I replaced an off-brand model with this one from Philips. What a huge difference!! I love the multiple settings depending on how deep of a clean I want! And the addition of the nozzle with the 4 way water splitter actually makes a difference. My favorite part of this water flosser is that the water hose is weighted at the bottom! Makes it so easy to use every bit of water in the tank! I'm very happy with the battery life. I've been using this every day for 2 weeks and I haven't had to charge it yet. It was very easy to take out of the box, quickly assemble, and get charging to use that night. Overall, I am very happy I upgraded!

Great, Cord-Free Option

Christy September 19, 2026

Upgrading to a water flosser can be a bulky commitment, but the Philips Sonicare Cordless Power Flosser 3000 is an excellent compromise for smaller bathrooms. I purchased this unit on March 30, 2026, specifically to avoid having a large, corded reservoir base taking up space by the sink and because I have periodontal disease. The standout feature of this model is the "Quad Stream technology," which splits the water into an X-shaped stream. This covers a wider surface area between the teeth and feels significantly gentler on the gums compared to older single-stream models, while still effectively targeting plaque below the gumline. The cordless design makes the device highly maneuverable, and the included USB charging cable makes keeping it powered very simple. The primary trade-off with this cordless design is the reservoir size. The integrated water tank holds enough liquid for about 45 to 60 seconds of continuous flossing. To do a thorough job on both the upper and lower teeth, you will almost certainly need to refill the reservoir at least once per session. Additionally, while it comes with a USB cable, the connection to the device itself relies on a proprietary plug rather than a universal standard like USB-C. Pros: Quad Stream technology provides thorough, comfortable cleaning over a wider area. Completely cordless and portable, keeping bathroom countertops clutter-free. Includes two different nozzle tips and a convenient USB charging cable. Cons: The integrated water tank is relatively small and usually requires a mid-routine refill.

Great product

Bob R August 4, 2022

[This review was collected as part of a promotion.] I got this cordless power flossed about 3 weeks ago and I can tell you this is a great product and definitely the answer to my problems. Brushing my teeth has never been a problem but I absolutely hate flossing in between my teeth. With this power flosser it gets water with just enough pressure in between my teeth and leaves behind a clean feeling. It's rechargeable battery makes it so convenient and easy assuring no wires get in the way. One only drawback would be its large handle making it a little cumbersome to maneuver but again not a big deal

Cordless flossing

Flossergirl July 10, 2022

[This review was collected as part of a promotion.] Cordless anything is always a plus for me! It comes with two nozzles. One for regular flossing and another that provides a quad stream for braces. It has two water pressure adjustments for cleaning and an additional button for deep cleaning. There are two ways you can fill the reservoir. The nozzles can be stored in the reservoir with the fill door open to allow the appliance to dry. I found the Phillips Sonicare flosser more than sufficient to do the job. However, I did find the placement of the buttons a little cumbersome. Because of how I gripped the appliance, sometimes I would turn it off while flossing. Overall it's a great device but a little awkward for me to use.

Works as it should

Jprinciotta August 12, 2022

[This review was collected as part of a promotion.] This flosser does exactly what it's supposed to. The battery life is perfect and the water reservoir is plenty. My teeth feel fresh after each use. I feel there are a few issues ide work on. The unit seems very bulky and I've also had som leaking from the reservoir fill area. Ide rather a more textured handle as well.

Water compartment poor design

Shanna R May 29, 2026

Honestly, I wanted to love this very much! But after having this product for just under a year. I noticed mold buildup where you added water. No matter how many times I air dry it, dry it out with paper towels. The design is just flawed. Ended up throwing away the water compartment entirely and use the top half only. Due to the tub it just safer and easier to use a cup

Don't order from Walmart on this product. The company said it would be delivered the same day. It arrived another I canceled the order four days later. Very bad driver experience and no customer interaction that where was this package for the last four days.
