I had one of those for a week, and I thought it was
pretty good. But I couldn't take the noise, so I got
a Fein Mini Turbo vac instead. This thing is very quiet- a lot
quieter than the Ridgid 4 gallon. I also found the suction action of
this machine to be a lot stronger, which was another plus. But
then it got me thinking about the Ridgid. See the Ridgid is
reported to have a static lift of 55' through a 1 7/8 hose. The Fein
model I have has static lift of 90' through a 1 1/4 hose. I could be
wrong, but if one were able to neck down the HOse on the Ridgid
to accomodate a 1 1/4 hose, it may come close to the suction
power of the Fein. Loudness of the Ridgid would be the real
compromise, but if you can live with it, it is the more cost
effective solution. Ridgid began phasing out just selling the 4
gallon by itself- you;ll have to pay for the wall mout kit, which
raises the price. If you can locate the vac and it's accessories by
itself, then jump on it. And then when you have time, see about
getting an adapter to allow you to neck down to the 1 1/4 hose
size ( as it turns out, the 1 7/8 hose size is not a very popluar
size, and there are not nearly as many accessories available for
this size as there are the 1 1/4 or 2 1/4 hose sizes).
Finally, the kit has the sound deadener (yeah, right) bolted onto
the vac, so you'll need to get a small hex key to remove that
peice if you want to use the vac as a blower. Just bear in mind
that removal can void the warranty (as explained to me by one of
the Ridgid reps).
