COSLUS C30 Portable Water Flosser Pick — 300ml Tank, IPX7 Waterproof & 8 Pressure Levels

The COSLUS C30 is a rechargeable portable water flosser pick that delivers adjustable dual-pulse streams and customizable pressure for precise, travel-ready interdental cleaning.

Built after five years of product development, the COSLUS C30 combines a large 300ml detachable tank, IPX7 waterproofing and an upgraded motor to offer dependable plaque and debris removal for people with braces, implants or sensitive gums. With four cleaning modes, an 8-level pressure range plus a DIY mode, it adapts from gentle daily care to deeper cleaning when you need it. Lightweight and USB-chargeable, the C30 is designed for home, travel and office use without sacrificing power or runtime.

How does the C30 handle sensitive gums and orthodontics?

The C30 provides a wide pressure range (30–150 PSI) and four modes—Normal, Soft, Pulse and DIY—so you can select gentler settings for sensitive gums or targeted pulses for braces. The included multi-functional nozzles reach around brackets and implants, while the motor’s dual-pulse streams enhance debris removal without aggressive brushing.

• 8 pressure levels for fine-tuning comfort
• Soft mode and pulse option for gum-friendly cleaning
• Four interchangeable tips for braces, implants and general use

What makes the tank and maintenance convenient?

The COSLUS C30 uses a 300ml wide-mouth removable water tank that fills quickly and detaches for thorough cleaning and drying. One fill supports about 90 seconds of continuous use, reducing interruptions and minimizing repeated refills during a session.

• Wide-mouth opening for fast filling and easy interior access
• Detachable design for deep cleaning and hygienic storage
• Single-fill runtime suitable for a full mouth rinse

How long does the battery last and how quick is charging?

The C30 charges fully in approximately three hours and provides up to 60 uses per charge under typical conditions, making it suited for regular home routines and travel. It ships with a USB charging cable (adapter not included), so you can recharge from common USB power sources.

• Fast three-hour full charge
• About 60 uses per full battery cycle
• USB charging compatibility for travel convenience

Is the C30 durable and safe to use in wet environments?

The device carries IPX7 waterproofing so it can be rinsed or used in the shower without damage, and the upgraded motor is built for long-term reliability. COSLUS backs the C30’s construction with materials and design choices focused on three-year durability under normal use.

• IPX7 rating for safe wet-area use and easy cleaning
• Reinforced motor for extended operating life
• BPA-free materials for internal water-contact components

Who this is for: The COSLUS C30 suits anyone seeking a compact yet powerful water flosser—especially those with braces, implants, or sensitive gums who need adjustable pressure and precise nozzle control. It’s a practical choice for frequent travelers, busy professionals, families looking for shared dental tools, and people who prefer a water-based alternative to string floss that’s easy to customize and maintain.
