And what do you do with these 4 vacuum cleaners?

Actually five.

1. Whole house (the motor works fine but there's almost no suction).
It used to work. Something is either stuck in the main tube or there is a
tear in the tubing. I can't find it since it must be within the walls.
So it's essentially useless.

2. Costco 8 amp wet/dry vac. It's OK but not all that good. I like that it
doesn't use bags, but that's about all I like about it.

That's what I used until I picked up these three to choose one from:

One will stay in the garage (for the cars).
One will stay in the cleaning closet (for the upper floors).
One will stay downstairs (for the lower floors)

But this whole question is off topic since all I really wanted to know is
how people felt about using amperage as a guide to suction power.
