Here is my review for those who are looking for a portable carpet cleaning machine. To me I'm new with the understanding of pumps, vac motors and so on but, it doesn't take a rocket scientist to figure out a portable machine isn't what I would purchase to kick off my new business with, especially having to be discouraged by using other ones. Well not until I did research after being told Cross American makes truckmount portable machines. Couldn't believe it. Comparing prices, size or for something that would fit in the back seat of my honda, aesthetics, and most of all suction. I am a certified cct and understand heat, agitation and all that oochie wallie wallie plays a big part in purchasing equipment. I also have to keep in mind my budget. I got to tell you The Cub is the way to go. Real small in size, light as a feather 45lbs or so, picked it up like nothing and walked up my stairs, awesome wheels to maneuver, easy to operate no confusion with multiple cords running across the floor, and here are my two favorites: (1) Truck mount suction and 300 psi. (2) prime and return hose gives you the option to pull them out of the solution tank and in to a gallon jug of your cleaning solution to use as a pre-spray. Just connect your spray gun to your solution line running from your portable and pre-treat. Pull the prime and return hose back out and into your solution tank of acid rinse and start cleaning. Don't forget to agitate. Lol. This machine kicks ass. Highly recommended. Any questions feel free to ask. Great job Ed Valentine and thank you for this machine!
