Motor almost stops pumping when in use. I've had other models over the years, but this one is utterly disappointing.
No, I would not recommend this to a friend.

We are sorry to hear that this is happening. It could just need the jet tip replaced or the unit may need to be cleaned. Here is a link to our cleaning blog that has detailed instructions. https://www.waterpik.com/oral-health/product-support/articles/how-to-clean-waterpik-water-flosser-vinegar/ If this does not fix the issue, please let us know! This model does come with a three-year warranty. Please email us at smreviews@waterpik.com or call us at (800) 525-2774 and we would be happy to help.
This is an excellent device! I did have difficulty the first two or three times with water spraying, but that has lessened significantly now that I have improved my acclimation with the device. I could tell the difference in my gums immediately.
