Which is better, the Professional formula or the Fiber formula on the usual wear areas?

Answer: BISSELL 2X Professional Deep Cleaning Formula is our premium deep cleaning formula. It does a great job while used with any of our upright deep cleaners. It tackles everyday messes and heavy traffic areas. Most importantly, it includes Scotchgard™ protection so you will be protecting your carpet and upholstery from future stains each time you deep clean.
