How to Use Mobile Public Toilets

The usage of mobile public toilets is similar to that of ordinary toilets, but adjustments to operational details are required based on the technical type and structural characteristics, as detailed below:

I. Basic Usage Process

1. Entry and Preparation

   • Observe the external signage on the toilet (such as the “Occupied/Vacant” indicator light), confirm it is vacant, then push the door open and lock it securely.
   • The interior is typically equipped with basic facilities such as anti-slip flooring, coat hooks, and vanity mirrors. Some high-end models also feature heating and cooling air conditioners or air purifiers, which can be used as needed.

2. Toilet Operation

   • Excretion Disposal:
     • The toilet bowl (or urinal) is connected to an independent disposal system below:
       • Recirculating Water Flush Type: Uses biofilm technology to decompose excreta, with the treated water recirculated for flushing, requiring no additional water source;
       • Dry Packaging Type: Excreta is collected in biodegradable plastic bags, which are automatically replaced after use, requiring no flushing;
       • Foam Sealing Type: Foam covers the surface of the excreta, sealing in odors and reducing the amount of water needed for flushing.
   • Automatic Flushing: Most models are equipped with automatic flushing toilet bowls that trigger flushing automatically upon standing up and leaving; some require manual pressing of the flush button.

3. Cleaning and Tidying Up

   • After use, dispose of paper towels and other waste in the trash bin to avoid clogging the pipes (not necessary for the dry packaging type).
   • When washing hands, if equipped with a water-saving faucet or sink, follow the instructions on the标识 (label); smart water-saving toilets may recycle hand-washing water.

4. Exiting and Ventilation

   • Confirm the door lock is open, then push the door open and leave.
   • The exhaust fan inside the toilet operates continuously to maintain air circulation; some models are equipped with background music or aromatherapy systems to enhance the user experience.

II. Notes on Differences in Technical Types

• Recirculating Water Flush Type: Requires no external water source, but biological agents need to be added periodically to maintain disposal efficiency.
• Dry Packaging Type: Completely waterless, suitable for water-scarce areas, but requires regular replacement of plastic bags.
• Foam Sealing Type: Foam solution needs to be replenished periodically to prevent sealing failure.

III. Instructions for Special Configurations

• If the toilet is equipped with a freeze-proof system or heating system, it can be used normally in winter; if the “Occupied/Vacant” indicator light malfunctions, confirm whether someone is inside by knocking on the door.
• For specific operational details (such as button functions, equipment maintenance), refer to the signage inside the toilet or contact the manufacturer for an instruction manual.
