What to Check Before Buying a Steam Cleaner for Fleet Vehicles
Steam pressure is the most important spec for fleet cleaning. Higher pressure, measured in bar, means better removal of grease and grime. Boiler capacity matters for runtime, as larger tanks reduce downtime for refills. Consider the weight and portability if you need to move the cleaner between multiple vehicles. Build quality should be commercial-grade for daily use, with metal components preferred over plastic. Check the heating time, as faster heat-up improves workflow efficiency.
Mistakes to Avoid When Choosing a Steam Cleaner
Do not choose based on price alone, as budget models may lack the pressure needed for heavy fleet grime. Avoid models with small tanks for large fleets, as constant refills waste time. Do not ignore the weight, as heavy units can be difficult to maneuver around vehicles. Avoid steam cleaners with plastic boilers for commercial use, as they are less durable. Do not forget to check the warranty and parts availability for long-term maintenance.
