Part of the answer is your preferences. Your inquiry was somewhat
vague: didn't specify upright or canister (or central). Shop vacs
would probably have a high rating except have too much suction: darn
nozzle keeps getting stuck to the floor because of "too much" suction.
Also, like canisters, some people don't like "that thing" following
them around getting caught on corners. OTOH some people don't like
shoving "that thing" around (uprights).
As far as suction, don't go by the bowling ball trick. How many times
are you going to attempt to suck up a bowling ball? Or even a tennis
ball. ...Now sucking up marbles, is a possibility. Sand, small
clumps of dirt, etc., become fast-moving projectiles and can shatter
the impeller (the fan that makes the suction). Shear off a fin, loss
of suction. Generally better to get a filter-first rather than a
fan-first. Also, the dirt should be deposited into the bag from the
top; with bottom-fill bags you are pushing the previously collected
dirt up to collect the new dirt.
One way to test for suction is to sprinkle sand on the store's carpet,
then grind it in a little. (A short-step walk back and forth across
the dirt field is sufficient.) Vacuum up the sand with the first
vacuum you like, then try the second vac. If the second vacuum picks
up sand it's picking up sand left by the first vacuum! Don't add sand
between the first and second vacuum's trials. Proper test is to
vaccum the test field with as many sweeps with the first vacuum as it
takes to get out all the sand, so the first one would indicate the
carpet is clean, then try with the second one.
