LOL!
Yes that surface cleaner does suck!
Literally it is supposed to suck, when you hook up
your vacuum hose to it!
The ANTV3 Vac Surface cleaner when used with the AZV55
will work fine with up to 100' of 2" vac hose I am told by
Hydro Tek, I have personally tested our floor model with 50'
of 2" hose.
Here is a link to the Tek Sheet on the ANTV3.
