Can I use Little Green Formula cleaner in my Pro Heat 2x upright cleaner?

Answer: This is actually a common question! It is not recommended that you use any portable cleaning formulas in upright machines. The Little Green Formula includes different ingredients meant to be delivered through BISSELL portable deep cleaners. For best results, I would recommend using Little Green Formula in your Little Green portable deep cleaner and 2X Professional Deep Cleaning Formula with your upright deep cleaner.
