Cordless Gem 5100 portable water flosser

The Waterpik Cordless Gem 5100 is a rechargeable water flosser designed for small bathrooms and travel. It uses PrecisionPulse technology to remove up to 99.9 percent of plaque from treated areas. A 7 oz removable reservoir provides up to 60 seconds of flossing time. The lithium-ion battery lasts up to 9 weeks per charge.

Upgrade from countertop or basic floss

This model replaces a bulky countertop unit or string floss when space is limited or a power outlet is unavailable. The jump is worth it for users who want cordless operation, shower-safe waterproofing and a travel bag with a transport lock. It is not for buyers who need more than 60 seconds of continuous flossing per fill or who prefer a larger reservoir capacity.

Simple daily routine with USB charging

Fill the reservoir with warm water, click a tip into the handle and select low or high pressure. The EASYSPIN 360-degree tip rotation helps reach back teeth. Charge via USB-C in 4 hours; a wall adapter is not included. Common issues include forgetting to engage Travel Mode during transit and losing the small specialty tips.

Questions about this item

What size sink or countertop space does the 7.1 cm x 12.8 cm x 23.6 cm unit need?

The flosser measures 7.1 cm wide, 12.8 cm deep and 23.6 cm tall, so it fits on a small bathroom counter or shelf; the 7 oz removable reservoir lifts off for filling at the tap.

How do I charge the lithium-ion battery and what indicates it is full?

Connect the supplied USB-C cable to any 5 V USB port; the battery indicator shows charge status and a full charge takes 4 hours, giving up to 9 weeks of daily one-minute use.

When should I replace the included tips and the reservoir?

Waterpik recommends changing tips every 3 to 6 months; the 7 oz reservoir is removable for cleaning and should be replaced if it cracks or leaks.
