Review on KEEPOW Compatible Powerfresh Replaces 203 8413 by Dre Fishburne

These caps fit the water bottle perfectly, but when the bottle is put in place in the steam cleaner it pops out after a few seconds preventing water from getting into the heated part of the vacuum. Maybe the rubber O-ring is a bit too big. That's about all I can make out because I can push it down for a snug fit and then it gradually starts to work loose from the bottom of the hole where the cap is inserted. Unfortunately I didn't keep my broken cap so I can't attempt to replace the O-ring on it. I could tape the water bottle but that seems like a pain as it would have to be re-taped every time the bottle needed to be refilled. Looking at the reviews I see that only one person had this issue so chances are the cap will work well for most buyers.
