Feature names hide different systems
Manual cleaning depends on accessible geometry, removable parts and surface durability. Steam-assist softens some residues but still requires wiping. Catalytic liners are material systems intended to help break down grease under specified conditions. Pyrolytic cleaning uses a high-temperature cycle and needs a construction, lock, insulation and control strategy designed for that purpose.
Compare the real customer task
Define the soil, cooking frequency, cool-down time and cleaning steps. Test baked-on grease and sugar-containing spills where foreseeable. Record which parts must be removed, whether water can enter controls or insulation, and how the finish changes after repeated cleaning. A short demonstration with fresh oil is not a life-cycle evaluation.
Review safety and instructions together
Cleaning chemistry, abrasive tools and water use can damage coatings or electrical parts. Instructions should state allowed products, cooling requirements and how to clean around heaters, sensors, fan guards and door glass. Pyrolytic ovens fall within the stationary-oven safety standard example list, but the exact appliance must be assessed to the applicable standard and market requirements.
