I get so many inquiries about what’s the best Truckmount and portables. Truckmounts I have down pat. Portables, not so much. In my rug shop I have a Nautilus MXE 500. It has 500 psi, a pump out, auto fill and great vacuum. But no heat. Great for rugs, but for daily use in residential or commercial, not so much. So what I’m asking, what features make the “sweet spot” for all around use?
