Make flossing part of your everyday oral-care routine with the Philips Sonicare Cordless Power Flosser 3000 in White. This rechargeable oral irrigator uses a focused stream of water to clean between teeth and along the gumline, including areas that brushing alone can miss. Its signature Quad Stream technology directs water through an X-shaped F3 nozzle that divides the flow into four streams, covering more surface area between teeth with less effort. Philips reports that the Cordless Power Flosser 3000 with the Quad Stream nozzle is up to 150% more effective than string floss at improving gum health after two weeks¹. This is a comparative study claim, not a guarantee of individual results. You can customize your flossing routine using two modes and three intensity settings. Clean mode provides a continuous water stream for everyday use, while Deep Clean mode uses pulses to help guide the nozzle from tooth to tooth. The Pulse Wave guidance in Deep Clean mode makes it easier to maintain a methodical routine rather than skipping areas. The removable 250 mL water reservoir holds enough water for a recommended 60-second session in Clean mode², and its side filling port makes refilling convenient. You can also twist off the reservoir to fill it directly and leave the fill port open afterward to aid drying. The slim cordless handle is easy to grip, and the nozzle rotates to help direct water toward difficult-to-reach areas. Two interchangeable nozzles are included: the F3 Quad Stream nozzle for broad coverage and the F1 Standard nozzle for a concentrated single stream when spot cleaning or removing food debris. Both click on and off for simple switching. The rechargeable flosser uses an included USB-A-to-small-plug charging cable and comes with a USB wall adapter. The Sonicare Cordless Power Flosser has a 40-days battery life. The package contains one White Philips Sonicare Cordless Power Flosser 3000, one F3 Quad Stream nozzle, one F1 Standard nozzle, one USB charging cable and one USB wall adapter. With its adjustable settings, two nozzle options and portable design, this water flosser offers a convenient way to complement your daily toothbrushing routine. ¹ Compared with string floss after two weeks of use with the Quad Stream nozzle, based on Philips' referenced study; individual results may vary ² In Clean mode; actual session duration depends on selected settings and use

Offers adjustable streams, but can be prone to misalignment.

The Power Flosser 3000 is the most efficient dental jet I have ever owned. In addition to cleaning my mouth in general, he also allowed me to discover that I had a bacterial focus on a tooth in the bottom inaccessible to brushing and that I was able to dislodge thanks to him. I have incorporated it into my oral hygiene routine on a daily basis and I am fully satisfied with it.

Very good product

philips.com

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, Cord-Free Option

I have had many of these. Always went for the cheap ones. They lasted between months to weeks. So I finally opted to give a brand name a chance and spend more. So far, so good. I would say save money in the long run and buy better quality.

Very good

I usually use a Waterpik corded flosser, which I like a lot. But I wanted a rechargeable battery flosser for travel. This works well, with a strong stream. Because of the battery, which lasts a long time on a full charge, the unit is somewhat heavy, and I wish the water tank were a bit bigger. But overall a useful device.

Good Rechargeable Water Flosser

Bought this after the dentist recommended one for my tween who has braces. There was water everywhere at first but once we got it down pat, it gives good pressure to rinse off teeth and gums well. There was a noticeable change right away, according to my daughter.

Good

Alexandros

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

Water compartment poor design

Philips consumer care

The model purchased is for reference HX386B1 and is therefore not exactly this one. He's very efficient but he dropped me after a year, while I trusted Phillips... The pump no longer delivers anything!

Not bad but not resistant

Seems a poor design to me. when applying it, the water and saliva coat the entire device, so I have to wash it off after every use. Oral B has a wand and hose, so only that part needs rinsing. Sonicare is a convenient size, but still leaves me dissatisfied.

Sub-optimal design

Large water reservoir.- nice. Control buttons are inconveniently located making it difficult to operate.  Jets of water lack pressure compared to previous Philips model.  Very bulky- making it hard to pack for travel. .

Unhappy with device

[This review was collected as part of a promotion.] It has a European style plug so I can't use it, and that was not indicated on the product webpage.
