Q: Is this item 110volts or 220 v ?

A: Choose a dual voltage model such as wp-560. Transformers will not work as 50 Hz will damage US/NA models.

Q: How long does it take to recharge the waterpix after the initial start up charge? There are no instructions or way to tell when the pix is recharged.

A: We are sorry for the confusion. The charging instructions are on page 9 under the Battery Care section of the manual. We recommend that you charge the unit overnight (8-10 hours) after every 6-8 reservoirs of water.

Q: Can this water pic be used in the Shower? Is it waterproof?

A: Yes it is! I use mine inside the shower without any issues!

Q: Can two people use with second pik

A: Yes it can be shared

Q: When they say "YES" it is waterproof are they talking about Waterpik - Cordless Plus Water Flosser - Blue Model:WP-463WSKU:6251484 Because it does not say so in the Spec's

A: The WP-463 Cordless Plus unit is water resistant, not waterproof. We do not recommend using this unit in the shower.

Q: (I have waterpik cordless plus) Should it light during charging? How could I know if it is charging properly and there is no any charging indicator?

A: This model does not come with an indicator light. We recommend charging the unit for 8-10 hours after every 6-8 reservoirs of water.

Q: How to clean water pic.???

A: Here is a link to our cleaning blog. It has detailed instructions on how to keep the unit clean and working at its best. https://www.waterpik.com/oral-health/product-support/articles/how-to-clean-waterpik-water-flosser-vinegar/
