Don’t be afraid to use this
Of course I was hesitant to use this because I was afraid it would block up the system in our very large 3 floor log home.  I took the plunge and was never so pleased with any product.  This was the first time the 8 inlet central vac ducting has ever been cleaned In nearly 20 years!  The amount of disgusting crud the product cleaned out was nothing short of amazing. And it left the house and system smelling so fresh!  If your home has a central vac, you need this product.
