Let me tell you why it is not a good idea to have a faucet or shower head attached oral irrigator.
There is no way to properly regulate the pressure and deliver pulsating irrigation.
A steady stream is believed to be harmful. Any pressure over 60 PSI is also thought to be harmful.
Therefore, you need a unit with a pump that does not go above 60 PSI and delivers a pulsatile stream.
Because of this, there will not be a shower or faucet attached model. If you believe this information is accurate, then you wouldn't want to consider a faucet or shower attached model either.
