Cleaning Modes and Intelligent Features
The VX300 offers a 3-in-1 cleaning function: vacuuming, mopping, and ground washing. It is designed to handle various types of dirt, from daily dry garbage to wet and dry mixed debris, and even stubborn air-dried dirt.

- Intelligent Stain Sensing: The built-in sensor automatically detects the degree of dirt, adjusting cleaning intensity and suction power dynamically for targeted cleaning.
- Voice Announcements: The device provides real-time voice guidance and reminders, such as "The water tank is short of water, please add water," "Roller brush is cleaning," or "The battery is low, please put it back on the base to charge." This makes operation intuitive.
- LED Smart Screen: A large LED screen visualizes the cleaning status, current working mode, remaining power, and usage reminders.
- Traction Force: The independent brush motor drives the roller brush, providing traction that makes pushing and controlling the scrubber effortless.
- Edge Cleaning: Designed for effective cleaning along edges and corners.


Cleaning Different Types of Dirt
- Daily Dry Garbage: Effectively wipes away dust, stains, and debris particles.
- Wet and Dry Mixed Garbage: Provides convenient and deep mopping and cleaning.
- Thick Air-Dried Stubborn Dirt: High-speed scrub cleaning ensures smooth and bright recovery of surfaces.

Maintenance
Self-Cleaning Function
The VX300 features a one-click self-cleaning function, eliminating the need for manual disassembly and washing of the roller brush after each use. Simply place the scrubber back on its charging base, and activate the self-cleaning cycle.

- The 8-point dispersive water flow cycle deeply cleans the floor brush.
- A 304 stainless steel wiper column scrapes out dirty water from the roller brush.
- Over 90% sewage recovery rate helps prevent secondary pollution.
- The 15-bar cleaning tank helps squeeze out dirt.
Emptying the Dirty Water Tank
After each cleaning session, or when prompted by the voice announcement/LED screen, empty the dirty water tank (sewage tank). The solid-liquid separation filter brush allows you to pour out water and filter solids at the same time, preventing clogging.

- Sewage tank capacity: 0.6L (600ml)
Drying the Roller Brush and Filter
The charging base comes with an air drying bracket. After self-cleaning, ensure the roller brush and filter cotton are properly dried to prevent mold and maintain hygiene.
