The best steam cleaners offer pressure per square inch (psi) of 65 and more, and temperatures over 295°, which is well beyond sanitizing and disinfecting levels. The benefit of vapor steam cleaners is they offer outstanding cleaning power for applications low-moisture cleaning applications. The heart of a steam cleaner is the boiler, which is available in either aluminum or stainless steel, which is the best metal for the ultimate in durability and longevity.
Always make sure to research the boiler construction because saving money purchasing an aluminum-based boiler with a shorter life span will most probably results in greater costs later. The best commercial steam cleaners and industrial steam cleaners come with at least stainless steel boilers. Sacrificing boiler quality can result in steam cleaner downtime and boiler replacement at costs up to and over $700.00.
The best steam cleaners are bundled with replaceable steam hoses rather than steam cleaner hoses that are permanently attached to the vapor steam cleaner. The major problem with attached hoses is an unexpected hose malfunction requires the user to ship the entire steam cleaner back for service, which can be distressing, especially if the steam cleaner is used frequently as is the case for most commercial and industrial steam cleaning applications.
