Mobile Toilet Three Guarantees
The 'three guarantees' policy for mobile toilets typically includes warranty duration, warranty scope, warranty responsibilities and procedures, additional services, and legal basis, as detailed below:

Warranty Duration: The warranty period for mobile toilets generally ranges from 1 to 3 years. Products with simpler structures and better quality may offer a 1-year warranty, while those with higher quality and more complex craftsmanship can have a warranty period of up to 3 years. Some manufacturers promise that if serious quality issues arise within 1 year from the date of use for mobile public toilets and their internal facilities, warranty services will be provided. For the modified parts of toilet vehicles or mobile restrooms, the warranty period is usually 1 year (excluding wear-and-tear parts).
Warranty Scope: Problems such as cracking or deformation of the main structure under normal use are typically covered by the warranty. Internal facilities like toilets and sinks that are damaged due to quality issues are also eligible for warranty. The automotive chassis part of toilet vehicles or mobile restrooms is covered by the chassis manufacturer's three guarantees, while the modified parts are covered by the modifier's three guarantees.
Warranty Responsibilities and Procedures: During the warranty period, if quality issues arise with the mobile toilet, the construction unit or manufacturer should fulfill warranty obligations and bear赔偿责任 for any quality-related issues. Upon discovering a problem, users should promptly contact the manufacturer, providing information such as the product model, purchase date, and fault details. The manufacturer will arrange for a professional to assess whether the issue falls within the warranty scope. If it does, repairs or replacement of parts will be arranged as soon as possible. For toilet vehicles or mobile restrooms, if quality issues arise with the modified parts during the three-guarantee period, the manufacturer will dispatch personnel to the site within 48 hours of notification; for chassis issues, users should contact the chassis manufacturer directly, with the modifier providing assistance as needed.
Additional Services: Some manufacturers dispatch repair or technical personnel every 3 months to visit the units using the products for routine maintenance and to communicate with direct users about product usage matters. After the warranty period, if the product is damaged, some manufacturers offer repair or replacement services at cost price to users.
Legal Basis: The warranty period for mobile toilets can be implemented in accordance with the relevant provisions of the 'Regulations on the Quality Management of Construction Projects', with specific durations varying according to different parts of the mobile toilet.
