Convenient
No more plugging in some pump.  Using our home's water pressure is most excellent.  Much more powerful than any electric pump device I've used before.  I really enjoy using a water-pick where I can adjust the temperature.  The irrigating brush attachments are nice for getting a really clean result without toothpaste.  The city water is flouridated anyway, it's practically an oral rinse from the tap.
