I have had a Coleman Shampoo vac for over 8 years, have only had to replace timer once, maybe they are not the best but I have a bunch of spares. I have only put 2 motors in the vac in 8 years and seldom does it eat brushes. I had a Fragramatics vac for 3 1/2 years brushes lasted 6 months, motors maybe a year, and when a timer went replacement was around $600, was told had to use only their timer. I dont know if they have changed anything I think mine was an older vac that were outsourced, and yeah they sucked to work on the tops, oh yeah and the coindrops are a pita!! The only - on my colemans are the hoses they use for frag. and shampooers. the guns and heads are the bomb, all stainless and last forever!!
