Hi Toney, Thanks for reaching out to us regarding the Sonicare Power Flosser. We are sorry to see the 1 star and hope we can improve your experience! The 600ml reservoir with easy flip lid, holds enough water for one cleaning. Have you noticed the different modes? You can enjoy a clean that's tailored to your needs! The Clean mode uses a continuous flow of water for a great everyday clean and the Deep Clean uses distinct pulses for a more thorough clean. You can also choose the Sensitive mode for an extra gentle clean for sensitive gums or the Massage mode which soothes and stimulates the gumline. We hope this helps! If you have any further questions, please feel free to get in touch via social media. We’re available 24/7 on Facebook and Twitter. Alternatively, you can reach out to us via the contact page on our website www.philips.com/support. One of our colleagues will then try their best to help you further. Hope to speak to you soon! Kind regards,
