Concern) Using an oral irrigator

Are there any people using Waterpik? I became interested and looked into it, and I found that there are several types of tips. If family members are using it together, is it correct to have different ones for each person?
Since there is a water container, it seems like you need to manage the machine after each use. Is it inconvenient? I am curious about the satisfaction level of the users! After brushing, do the hidden debris come out?
