VSITOO S1 Max Smart Insulated Water Bottle, White, 33 oz, UV-C Self-Cleaning, Touchscreen and App Control

The VSITOO S1 Max is a 33oz insulated stainless steel water bottle with automatic UV-C self-cleaning, app control, touchscreen status, and 24-hour cold retention.

This smart bottle combines durable double-wall stainless steel insulation with a self-cleaning UV-C system and a companion app so you can keep water fresher between washes. Thoughtfully engineered in the U.S., the S1 Max balances large-capacity hydration, safety features that disable UV when open, and a long-lasting rechargeable battery for everyday use at work, the gym, or on the go.

How does the self-cleaning UV-C system protect my water?

The bottle uses an internal UV-C emitter that runs automatic cycles based on AI sensing of usage patterns. The system pauses whenever the cap opens or the light is pointed toward a person, then resumes only when the bottle is upright and closed, minimizing exposure risks.

• AI-triggered cleaning cycles tied to user behavior
• Automatic shutdown if cap opens or light faces outward
• Resumes cleaning only when bottle is closed and upright
• Built-in safeguards to protect skin and eyes from UV exposure

Can I control cleaning and check temperature from my phone?

Yes — customize cleaning schedules and monitor bottle status through the VSITOO app, or operate the main functions directly from the bottle's touchscreen. Temperature feedback uses color cues on the display for quick, at-a-glance info.

• App scheduling and remote cycle start
• Touchscreen for manual control and instant status
• Color-coded temperature display for fast reading
• Magnetic charging with up to 30 days battery life per charge
