Quick answer
Choose the White Ultra Plus (WF-150) if you want a larger reservoir and more tip options for comprehensive cleaning. Pick the Black Ultra (WF-112) if you prefer a compact countertop flosser with 5 specialty tips and a lower price.
Reservoir size and tip selection
The White Ultra Plus (WF-150) features a high-volume reservoir, which means fewer refills during your routine. The Black Ultra (WF-112) has a smaller tank, so you may need to refill it once or twice depending on your cleaning time.
Both models include specialty tips, but the Black Ultra comes with 5 tips to address different needs like plaque removal and orthodontic care. The White Ultra Plus also includes multiple tips, but the exact count and types differ—check the package to match your specific oral care goals.
Pressure settings and customization
Both the White Ultra Plus and Black Ultra offer 10 adjustable pressure settings, giving you full control over water intensity. This is useful whether you have sensitive gums or prefer a deep clean.
The 360-degree tip rotation on both models helps you reach every area of your mouth without repositioning the handle. The main difference comes down to the reservoir size and included tips, not the pressure range.
