Why does it hold enough water for only 30 seconds when you're supposed to use it for a minute?

As a travel product. compact size is critical. Yes, the fill tank lasts only 30 seconds, but I can accept this tradeoff rather than having a fill tank twice the size and thus taking up that much more room in a carry-on suitcase. Also, as a travel product, it's not meant for daily use over an extended period of time. At least for me, a set of alkaline batteries is good for 25-30 uses on high speed. This is more than enough for a trip. The lithium battery version costs a lot more, weighs more, and is bulkier. I'll opt for the disposable alkalines!

Well... I liked the Flosser, until after less than 2 months it stopped working. But Waterpik, after I answered questions, sent me a new one right away. They said they'd send info on cleaning but I don't have it yet. Just got the replacement so will have to suspend judgment a bit, but I did really like it before. By the way, very difficult to replace batteries and with that first one had to do it 3 times in 2 months before it stopped working altogether - probably the on/off switch.

What's the difference between this one and the WF-03?

Hello Marshall- The functionality is the same for both units. The main difference is the WF-03 comes with a travel bag and plug. Here is a link comparing the two units: https://www.waterpik.com/oral-health/products/compare/WF-03CD010/WF-02W010/

The water vessel can’t hold much water. I’m having to fill it twice to floss both upper and lower teeth. Is this common?

Hello there- The reservoir on the WF-02 Cordless Express holds five ounces of water. This model is designed to be small as it is intended for those who travel and/or have little counter space. Some users may find it necessary to fill the reservoir more than once. If you are finding it to be a hassle to refill the reservoir, a counter top model would be a better fit. We would be happy to help! You can email me directly at smreviews@waterpik.com for assistance.

The product has a quality void, stopped working after 6 months

The product is a void and should not be bought from the seller as it stopped working after 6 months .. iv used the best rechargeable batteries and the flosser seems to loose power after few second of use. Bad quality

Was excellent but broke within 4 months

I ordered my water flosser back in May and used this daily. It’s excellent for cleaning, very easy to use but I was disappointed it stopped working after 4 months. I have tried new batteries and attachments, and it no longer works and sadly past the refund window. The only negative about this particular model is it requires batteries (AA) and they run out very fast and it’s unsustainable for long-term daily use. I did use rechargeable batteries but sadly the device no longer works. I have ordered a different Waterpik model that uses electric charging and keeping my fingers crossed this is better!

Over 2 years old and still works great!!

This thing is the best!! I have had zero issues with it and I’ve had it for over two years! So easy to use. The batteries don’t run out quickly. It’s quiet, easy to hold and I love that it doesn’t have a cord!! It has never leaked like other inferior brands. I bring this everywhere when I travel and it fits right in my travel case. The attachments are super easy to remove and put back on.
