I had high hopes for this product. A friend recommended the Spot Bot but, when I saw the great reviews and portability of this item, I thought I'd found a perfect replacement as I travel a lot. The concept is great however, the capability of its' suction is terrible. The carpet is left incredibly wet - and let me clarify that I have all low-pile area rugs. These are by no means thick carpet. I measured 6 oz on a test spot and completely emptied it... after scrubbing and utilizing suction to pick the formula back up, there was a sad 1 oz of liquid in my waste tank. 1 ounce. I'm disapppointed. I should've just got the Shop Bot. I may return but honestly hate dealing with the repacking/return process. We'll see!
