Waterpik Cordless Express Water Flosser vs Waterpik Cordless 1200 Water Flosser

Both are Waterpik cordless flossers with two pressure settings and ADA acceptance, so the real split is power. The Cordless 1200 is rechargeable, runs up to 45 seconds per fill and ships with a Precision tip and a Tongue Cleaner tip. The Cordless Express runs on three AA batteries and gives about 30 seconds per fill, which suits a travel bag or a bathroom with no outlet. Owners of both rate them 4.4 out of 5; the 1200 has more ratings behind that score. Buy the 1200 for daily home use and the Express for travel or backup.

• Choose the Cordless Express if you want a flosser that runs on AA batteries and never needs charging, for travel or a bathroom without an outlet.
• Choose the Cordless 1200 if you floss daily at home and want a rechargeable battery, a longer 45-second run per fill and the Precision and Tongue Cleaner tips.
