Anyone own a very small AC powered vacuum cleaner that you're happy with?
Or, one that you hate? That's useful information, too.

Get a small wet/dry shop vac. You will want high HP for a lot of
suction, but see if you can find one that has a small "gallon" rating
to facilitate stowage. If you have to do any sanding, you can run a
hose to the shop vac and keep the marina manager happy. We have tried a
series of toy vacuums over the years with less than spectacular
results. Nothing works as well as a small shop vac. You can get
fittings for carpets, etc, of course.
