Cordless Pulse 3100 Portable Water Flosser, Rechargeable, Blue

The Waterpik Cordless Pulse 3100 is easy to use and does a great job cleaning between teeth and along the gumline. The cordless design makes it convenient for everyday use, and the rechargeable battery lasts a long time between charges. It has enough water pressure to leave my mouth feeling fresh without being uncomfortable. The water reservoir is easy to fill, and the overall quality feels durable and well made. I’m very happy with this flosser and would definitely recommend it.

I use this Waterpik all the time and it's become a regular part of my daily routine. It's easy to use, rechargeable, and does a great job helping remove food particles and debris from places that brushing alone can miss. I like the cordless design because it's convenient to move around and doesn't take up much counter space. The water pressure is strong enough to be effective, and the different settings make it easy to find a comfortable level. After consistent use, my mouth feels cleaner and fresher, and I appreciate how quick it is to add to my routine. Overall, this is a reliable water flosser that I reach for every day.

I have the regular size one but needed this portable for a vacation. I am impressed with its performance given its compact size. It is comparable to the one I have at home. The water does run out rather quickly given the small holding capacity. I did need to fill it 2x to get the job done but other than that it’s great. It holds a charge so no need to keep it plugged in. It’s quiet, no leaking, size is as expected. Happy with purchase.

I’ve really enjoyed using my Waterpik. It leaves my mouth feeling much cleaner than brushing and flossing alone. It’s easy to use, gentle on my gums, and does a great job removing food particles from hard-to-reach areas. I noticed my mouth feels fresher after every use. Overall, it’s a great addition to my daily oral care routine, and I would definitely recommend it.

This was an inexpensive waterpik but it works great and the battery lasts. Don't have to worry about getting it wet, especially new waterpik users getting used to decrease splash. You don't have to worry about it getting wet, just concentrate on your technique. I use it three times a day and the battery goes for a couple week or more without recharging. Effective and great price. You don't need the expensive, even higher pressure pik which could irritate gums or break the seal around implants pushing in debris with possible infection. Works great!

Updated review, 04/03/26: The second Waterpik Cordless I received about six months ago leaked from the moment I first used it, so - like the first one I owned that lasted 18 months - this one has to live on a folded paper towel to prevent it creating a little pool of water on the sink surround. It works well, but I am unable to see that the design of it has changed in any way since I bought the first one. That suggests that the manufacturer is not troubled by reviews such as mine that question the quality of their product. Next time I need a water flosser I'll look elsewhere. Original review: I am having my second Waterpik cordless flosser delivered today. The reason I'm buying again a product to which I've given only three stars is that I'm not aware of any alternative similar product. If there were one, I'd definitely try it out. I owned the first one for a year and a half. Personally, I consider that unsatisfactory, but you will find reviewers whose flossers lasted far less than that. Here's what happened with the first one: I bought it almost exactly 18 months ago. It worked OK for about a year, being used once a day, every day. At some point the two-speed switch stopped offering a slower speed: I don't know quite when, because I always use it on high speed. Around its first anniversary the base started leaking slowly, so I stood it on a folded paper towel when not using it. The problem was not severe, because there was very little water left to leak after use. Nevertheless, not very good. A week ago it refused to charge. This turned out not to be a defective battery but a problem with the USB-C connection on the side. This connection is "protected" against water by a rather awkward rubber plug, but it doesn't seal very well. While troubleshooting it, it became clear that the USB-C is picky, and some plugs won't work at all. Possibly certain chargers don't work either. I urge potential buyers to read all the reviews before making their purchasing decision. It is clear from the reviews as a whole that a) the quality of construction leaves something to be desired; b) the company can be unhelpful when it comes to warranty claims. You will have to be the judge as to whether these potential issues justify the asking price. As I said, I'm purchasing a second one right now. If this doesn't do better than the previous one, I'll look elsewhere next time.

I bought this as a gift for a friend who has braces, and according to him it has been one of the best things he’s added to his dental care routine. He liked it so much that he even asked me again for the product link so he could recommend it directly to his orthodontist. Personally, I’ve been using the Waterpik Aquarius for about two years now, and it completely changed the way I approach oral hygiene. Because of that experience, I already trusted the brand before buying this portable version, and it definitely lived up to expectations. My friend travels constantly, and he says this has become an essential item in his travel bag because it’s practical, easy to carry, and still powerful enough to keep his teeth and braces clean while away from home. Overall, Waterpik continues to impress me with the quality and reliability of their products. Highly recommended brand.

Review is based on transitioning from a countertop unit with a large capacity tank to this unit. This reservoir holds MUCH less water. Just be prepared to refill it several times. It is bulky and takes getting used to. Does it work, yes. Is it an adjustment from a countertop unit, yes. Your call!
