Our 1-1/8 Milwauke hammer took a dump after only about 15 years. I am sure the Bosch will not last as long but it seems nice at first glance.
I am really excited to try out the Greenlee 390. Yes, it is a $500 5-gallon bucket vacuum. Awesomely portable. Incredible power. We do a lot of gas station wiring. That means many 100 - 200-ft underground conduits to clean out and blow pull strings through. We have been getting by with shop-vacs for years. We were in need of a new one so I figured I would check out the specs:
Shop vac: 6hp, 181cfm, 63 inches water column (true measure of power).
390: 1/2hp, 101.2cfm, 137.1 inches water column.
I have to laugh at consumer specs. Really? 6hp with less than half the lift of 1/2hp. And who really cares about cfm's in a vacuum? Maybe you haven't handled a powerful vacuum before but this thing will suck your face off. I am sure nobody cares but thanks for reading anyway.
