Put some stocking or other pine mesh over the tube of a vacuum
cleaner (wet/dry shop is best especially for shower drain that
holds more water).
The wet/dry shop vac is not just best. It’s a must. If you use
anything else for this, any drain will have water in it, and you can
destroy the motor on most ordinary floor vacs. It HAS to be a vacuum
intended for wet pick up.
The same is not true, however, for a useful jewelers variation on
this. Drop tiny items on the floor? Have trouble seeing the things,
perhaps on a carpet or just there? Or perhaps you’ve not dropped just
something, but a whole box or lot of tiny somethings. Do the same
with (this time, any type) vac, and you can pick up a whole lot of
little somethings from the floor with less effort that one by one
with fingernails… My home shop is in my basement or what the
former owners used as a rec room. It has tight low pile berber carpet
glued to the otherwise concrete floor. I didn’t try to pull that up
when I turned it into my shop. Nice to walk on, etc, but finding the
melee that drop is a pain on this carpet, even if it’s tight enough
that things don’t drop down into the surface. Can’t just sweep it up.
But the vacuum with a nylon works fine.
