Well, they don't show much about the filter and how easy it is to
empty/change. Most shop vacs seem to attach the filter to the motor
assembly on the top. Real pain to keep all the dust/dirt in the machine
while removing the motor assembly. Crap gets all over the outside and
floor, then you have to vacuum up the crap on the floor after changing
From the pictures, this unit retains the filter in the main housing
when removing the motor assembly. Then you can remove the filter and the
dry crap. If true, this is a much better unit!
My $0.02 worth!
I know a guy who services Rug Doctors at grocery stores that rent them
out.... The Rug Doctors that you can rent have a little sticker on them
that says "To purchase a Rug Doctor,,," and gives a phone number and the
I asked him about that once, mainly if the ones they sold were the same
as the ones they rented. He said they weren't. The two looked kinda
alike and basically worked the same but the ones they sold were not
built as tough--the ones they sell cost $600 but the rental ones have a
replacement cost about twice as much, and were built more durable
overall to survive a life of being a rental machine.
The main benefit I have heard for using 'industrial' floor vacuums is
that the little parts wear out--agitator brushes and stuff like that,
and with a commercial machine there is going to be a simple source of
replacement parts that should be available over several years at least.
Vacs sold for home-use don't normally have that kind of parts support.
That's only an issue is you use them really, really a lot though.
