8-Inch Professional Pressure Washer Surface Cleaners

CARB is an acronym for California Air Resource Board, and has to do with the emissions that are associated with small power equipment engines. CARB-compliant products have engines that meet more stringent air-quality standards. If your state requires compliance for gas powered equipment, confirm that your model is CARB-certified before you buy. While CARB-compliant models run cleaner than noncompliant models, they still emit some pollutants.
