Quality Issues of Mobile Toilets

The quality issues of mobile toilets are mainly reflected in four aspects: false labeling of sewage discharge technology, shoddy materials, easily damaged facilities, and persistent odors.

False labeling of sewage discharge technology is a prominent quality issue with mobile toilets. Some low-cost merchants attract customers by claiming their products have a "zero-emission" function, but in reality, they only use simple direct discharge or rudimentary treatment methods, lacking formal third-party environmental testing reports. This false labeling leads to mobile toilets being required to undergo rework and rectification due to non-compliant emissions during environmental inspections or scenic area ratings, increasing costs for users and potentially causing environmental pollution risks. For example, certain scenic areas have been ordered to rectify their mobile toilets for non-compliant sewage discharge within a specified time, directly affecting operational efficiency.

Shoddy materials directly impact the service life of mobile toilets. Some merchants reduce costs by using thin iron sheets instead of reinforced steel structures, ordinary color-coated steel sheets instead of metal carved panels, and simplifying anti-corrosion and waterproofing processes. These shoddy practices make mobile toilets appear similar to qualified products in appearance, but their actual service life is shortened from over 10 years to 2-3 years, significantly increasing later maintenance and replacement costs. For example, a scenic area purchased mobile toilets that suffered severe rust and structural deformation after two years of use due to material issues, requiring a complete replacement.

Easily damaged facilities are a common problem in the use of mobile toilets. Taking highway mobile toilets as an example, some products have issues such as faucets not dispensing water and door locks breaking easily, which not only affect user experience but may also lead to safety hazards due to facility failures. For example, a mobile toilet at a highway service area trapped a user due to a broken door lock, raising public concerns about the safety of mobile toilets.

Persistent odors are a widespread problem with traditional mobile toilets. Over 60% of users express dissatisfaction with the "strong odor" in public toilets, mainly due to improper handling of excreta leading to secondary pollution. Some mobile toilets use simple septic tanks or direct discharge designs without effective deodorization systems, causing odors to spread and affecting the surrounding environment. For example, a scenic area's mobile toilets were complained about by tourists for odor issues, requiring the installation of deodorization equipment and an increase in cleaning frequency to improve the experience.
