Summary: Use as pre-treat stain remover
Comment: While I do have the Bissell Little Green - I have had most success with using this as a pre-treat rather than in the machine. It even gets out older stains and using it as pre-treat makes it last longer - you don't have to thow away the unused portion if you only have a small area to clean.

Summary: Can Get Expensive Fast
Comment: A bottle was included in the Bissell SpotBot box along with sample bottles of the regular carpet cleaner. The sample bottle was used up quickly because so much must be added to fill the SpotBot cleaning reservoir up to the OXYGEN2 line. I didn't notice any difference in results on the carpet whether or not I used this "next generation of oxygen boost", so I didn't buy any more of it until recently. Several spots on the carpet hadn't come clean even after several cycles with the SpotBot. Even a spritz of the normally reliable Rug Doctor spot cleaner couldn't remove those recalcitrant spots. For seven dollars, the 32-ounce container of OXYGEN2 was worth a gamble. I was curious to see how it would fare.
The Tests
The SpotBot is a small machine that cleans carpet stains with a solution of water, cleaner, and, if desired, some OXYGEN2. It's programmed to squirt on the solution, agitate the area with its circular brush, and then vacuum up the liquid. A beep alerts the user that the cycle is finished. Probably 98% of the time I get up spots easily with just water and half the recommended amount of soap. For the few failures Rug Doctor almost always come to the rescue. What I don't like about it is the suggested ratio for the cleaning solution. The solution tank holds 32 ounces. When using OXYGEN2 the user is guided to use 16 ounces of OXYGEN2, and 8 ounces each of water and cleaner. The seven-dollar container of OXYGEN2 only holds 32 ounces, so those who follow directions will soon exhaust the supply. The cost factor and some skepticism are the reasons I hadn't bought OXYGEN2 until now.
I decided to try the OXYGEN2 on some residual stains that were mostly late discovered stealth pee damages. There were four of them and with the OXYGEN2 all but three came clean. I decided to return to the one stubborn yellow tinged spot later.
I poured grape juice on two places on an old piece of carpet and cleaned with just water and cleaning solution. The grape juice came out totally. However, next to one grape juice spot was an old stain that had been there forever and hadn't come clean whatsoever. Out of curiosity I squirted the spot with a little OXYGEN2 and cleaned it again with the SpotBot using OXYGEN2 in the solution. Amazingly the spot totally disappeared, and I was starting to become a believer in a product whose efficacy I had always doubted.
On two basement rugs I poured some grape juice, rubbed it in and let it set overnight. One of the two stains was pretreated with OXYGEN2. Twenty hours later I set the SpotBot on both using the recommended ration of solution with OXYGEN2. Both stains came out easily using the regular 3-minute cycle. I opted not to use the SpotBot's six-minute set in stain option. Again, next to one of the grape juice stains was a very old stain that remained even after the OXYGEN2 bath. I poured OXYGEN2 directly on this stain of indeterminate age and origin. The stain actually seemed to dissolve somewhat right before my eyes. I then gave the ancient stain another go with the SpotBot and OXYGEN2. It came up totally!
There was more of the same ancient stain on another part of the rug so I attacked it with a non- OXYGEN2 solution and no pretreating to see what would happen. After the cleaning, the stain was a little less pronounced but definitely still there. A follow up with OXYGEN2 took it out.
For the grand finale I made two grape juice stains, gave each a topping of mustard, and let them sit overnight. Three cycles with the SpotBot and pretreatment with OXYGEN2 didn't budge the mustard. If anything it accentuated and brightened the yellow. I pretreated the other stain with Rug Doctor stain remover and had better success, though a tinge of yellow remains in the carpet.
With the little bit of OXYGEN2 remaining I doused that previously cleaned stealth pee stain in Spud Central. After another run of the SpotBot over it, there was marked improvement, but not total cleansing. To be fair, OXYGEN2 is not for pet stains. Bissell markets another product for urine damage.
FINALLY - I had mixed success with OXYGEN2. If I were to buy it again, I'd use it to pretreat stains or use it as a weapon of last resort. Using 16 ounces of OXYGEN2 per filling in the SpotBot or any other rug cleaner can get expensive.
