Executive Summary
Cleaning solution material compatibility is not a universal "compatible" label. Water tanks, hoses, pumps, seals, and metal components may use different grades and surface treatments and must be evaluated separately under conditions close to actual concentration, temperature, time, and stress.
Who Should Read This
- Brand, R&D, and quality teams developing cleaning solutions for robot vacuums
- OEM procurement teams needing to confirm material risks of target equipment
- Engineering personnel handling complaints of cracking, swelling, leakage, discoloration, or corrosion
Who Should Not Rely on This
- Projects that cannot obtain material information yet claim compatibility with all devices
- Teams planning to replace full-machine validation with a single short-term visual immersion test
How to Conduct the Assessment
- Establish a real material list, including grades, colors, fillers, seal forms, and metal surface treatments.
- Define actual and accelerated conditions: formula, concentration, water quality, temperature, time, cycles, flow, and mechanical stress.
- Retain unexposed baselines and appropriate controls; record test coupon and component batch numbers.
- For plastics, evaluate mass, dimensions, appearance, color, cracking, and necessary mechanical properties.
- For elastomers, evaluate volume, hardness, strength, compression, or sealing changes; for metals, evaluate mass and localized corrosion.
- After screening passes, re-verify functionality with real components and target machine procedures.
B2B Specifications
B2B material compatibility tables should list material grade, component, surface treatment, sample batch, pre-treatment, cleaning solution batch, concentration, water quality, temperature, time, stress, controls, replicates, and pass/fail criteria. Acceptance limits must be determined by equipment design and project risk; conclusions from other models may not be copied.
Comparison of Approaches
Standard coupon immersion:Convenient for screening and quantification, but may lack real stress, geometry, and surface state.
Real component testing:Closer to assembly and sealing, but more batch and structural variables.
Full machine cycling:Allows observation of pump path, leakage, and functional performance; should follow the first two screening stages.

Conclusion
Reliable material compatibility conclusions must be tied to actual materials and actual use conditions. Select indicators separately for plastics, elastomers, and metals; set controls and proceed stepwise from coupons to components to full machine. Conclusions cover only the tested combinations.

Frequently asked questions
Why can't a universal compatible label be used directly?
+
Because different material grades, surface treatments, concentrations, temperatures, times, and other conditions vary, testing must be performed separately for each actual combination.
What indicators should be focused on when evaluating plastics?
+
Plastics typically require evaluation of mass change, dimensional change, appearance (discoloration, cracking, etc.), color change, and necessary mechanical properties.
What special requirements are there for metal corrosion testing?
+
Metal corrosion testing should focus on localized corrosion rather than uniform corrosion, use actual surface treatments, and refer to standards such as ASTM G31.
