Panasonic Water Flosser Review (EW1611)
Reviewed by the waterflosser.au editorial team · Published July 2026 · Updated August 2026 · 8 min read
Panasonic isn't the first brand people think of for dental care, but the EW1611 has built a loyal following in Australia for two specific reasons: it's IPX7 shower-safe, and it's noticeably quieter than most competitors.
Standout features
The shower-safe rating means you can use it wet-handed without worrying about water resistance — genuinely useful if your routine happens in the shower rather than at the sink. The motor is also markedly quieter than the Waterpik or Colgate units, which matters if you're flossing early in the morning or late at night in a shared house.
Where it's limited
With only 2 pressure settings and a 130ml tank, the EW1611 is built for simplicity rather than customisation. It's not the pick if you want fine-grained pressure control for sensitive gums or braces — the Waterpik Cordless Advanced does that better. Battery life (around a week of typical use) is also shorter than Waterpik's roughly two weeks.
Panasonic's track record in personal care electronics
Panasonic has manufactured personal grooming and oral care electronics — electric shavers, hair clippers, electric toothbrushes — for decades, which shows in the EW1611's build quality even though water flossers are a smaller part of the company's product range than for a dedicated dental brand.
Who it's for
If noise and shower-use are your priorities — say, you live with a partner or housemates and don't want to wake anyone — the Panasonic EW1611 is one of the better options in its price bracket. For maximum flexibility and pressure control, look at the Waterpik Cordless Advanced instead.
Frequently asked questions
Can I actually use the Panasonic EW1611 while showering?
Yes — its IPX7 rating covers wet-handed use and brief water exposure, which is the specific design intent behind this model, unlike most water flossers that recommend keeping the handle dry.
Is the Panasonic EW1611 good for sensitive gums?
Its lower pressure setting is gentle, but with only 2 settings total you have less fine control than a 5-to-10-setting model. It's a reasonable option for sensitive gums but not the most adjustable choice available.
How does Panasonic's warranty compare to Waterpik or Philips?
Panasonic typically offers a standard consumer electronics warranty (check current terms at time of purchase), broadly in line with what Waterpik and Philips offer on their water flosser ranges.
