Questions about this item

How loud is the Waterpik Onlyone FC5090 during its 1,500-2,000 pulses per minute cleaning cycle?

The flosser runs at a low hum typical of cordless oral irrigators; the 1,500-2,000 pulses per minute are designed for quiet bathroom use without disturbing others.

Which USB power source do I need to recharge the 30-day battery?

Any standard 5 V USB port — laptop, phone charger or power bank — will recharge the unit in about 3 hours using the included cable; no proprietary adapter is required.

Will the five included jet tips fit older Waterpik handles I already own?

The package supplies five colour-coded tips (standard, orthodontic, periodontal pocket, tongue cleaner, nasal) made for the Onlyone FC5090; compatibility with other Waterpik models is not guaranteed.
