All that "Peak horsepower " is a lot of bunk. It is impossible to run 6 HP on 15 amps@110 volts,period!! There just isn't enough amperage. Ever take an old vac apart and look at the armature of the motor? It will have a shaft of 1/4" to maybe 3/8"(and,that's hoping for too much!
If you want a DECENT vac that will be just as powerful as the biggest Sears vac,but not noisy at all,bite the bullet,save up your pennies,and get a FEIN vac. Not the smallest one,the mid size one. It comes with about a 1 1/2" LOOONG hose. But,what I like is that you can jam a plastic Sears 2 1/2" hose into the hole left when you take the original hose off( WHAT? Do they make SMALLER shavings in Europe?). I REALLY like that you can connect a sander to the plug in in the vac,hook up the sander's hose to the vac,and when you turn the sander on,the vac comes on. And it goes off a few seconds after you turn the sander off! I have used it with my Bosch electric planer(with the help of a few coils of sand paper). It effectively gets all the planer's chips!
