45 SECONDS - Small water holder I think the pic is to small if you want to do a more through job irrigating your teeth
Response from waterpik.comBy Waterpik Product Support, July 31, 2025
Hello lloyd241 - We're sorry to hear you're not completely satisfied. The reservoir has a capacity that allows for up to 45 seconds of use and can be refilled as necessary.
Less effective than the corded version of it, the Waterpik® WP-580 still offers decent performance for users prioritizing portability. While its cordless design makes it convenient for travel or smaller bathrooms, the water pressure and tank capacity fall short compared to full-sized, corded models. The rechargeable battery is a plus, but it can weaken over time, leading to inconsistent pressure. It's good for light flossing needs, but those with more intensive dental care routines may find it lacking. If you value power and continuous flow over portability, sticking with a corded model might be the better option.
The first one had to be reset before each charge. Waterpik replaced it and the new one works perfectly. I previously used a counter model. I love the rechargeable version.
