Orange Glo is a lot less expensive, so if you're on a budget, you will probably choose Orange Glo over Mop and Glo. One of the reasons it's less expensive is that Orange Glo doesn't have the OxiBoost technology. OxiBoost helps fight the bad odors in your house by breaking down the chemicals in the air. It's more difficult to get Orange Glo to remove stains on carpet, but it does do a decent job, so it's still worth using if you have stains you want to get rid of. Mop and Glo outperforms Orange Glo in carpet cleaning, but it's more expensive, so keep that in mind when choosing between the two.
