Anyone help me figure out whats going on? Have new Legend XL (400 hrs).I will be sucking rug at one point (wand is sounding great as I lift it off the carpt, then moments later my sucking power decreases. It has been doing this for the past few days. My waste tank gaskets look good around perimeter and I don't hear any leaks. Vac hoses are clean and in good shape. Hose between vacuum inlet and strainer basket is clean. Belts don't seem loose. Anything else I need to be looking for? Thanks for any help that is thrown my way. Mark
I would be willing to bet you a Slab of ribbs from the Quarters BBQ. That it is a foaming issue either from to much chemicle in your rinse or from your prespray or customer using woolite. Try putting some powedered defoamer on the carpet so as you clean it will suck it up. good luck NICK NELLOS
Hey Nick You might be on to somthing, I did look in my wast tank today as we were cleaning today. I had the issue with loss of vac and went out to shut it down to try to figure it out. Looked in waste tank and there was alot of foaming going on. My tech seems to over prespray at times. I am hopeing this was the prob. The first job today went well. All the way to the end. The second job was a nasty and thats when this happened today. Why does this cause vac loss?
The foam stops the amount of air that flows to create the vacuum, its a real pain, you'll notice when you're cleaning a carpet that the home owner tried to clean. It could also be from a previous company. When you first walk in, and the whole carpet looks uniformally soiled, it would be a good guess that there is some sort of residue. As Nick said apply a defoamer to the carpet first, that will help limit it.
Or switch presprays. Some are way too foamy imho. Also keep a bottle of liquid defoamer handy. If you use it and see a marked difference immediatly then you have found your problem.
The foam "coats" the vac line, causing restriction, loss of vac. (good call Nick) Try putting down some powdered defoamer prior to extraction. Some great advice here. It could very well be the prespray you are using. Or if you are using emulsifier, it could be metered too high.:burnout:
