I also have a Proteam Super Coach 6. So a lot of my comments are relative to that one. 1st the negatives. Obviously, the suction is much less. 80 CFM vs 150. So the cleaning power is not near as deep. The turbine driven carpet head does not work very well on carpet with much nap. It stalls. My biggest complaint though is the harness. It is very poorly designed. The webbing for the straps are far to light weight. I have had the thing fall off my back many times, because the straps slipped through the buckles. The plastic buckles obviously intended for heavier webbing. Luckly, it hasn't been broken by hitting the floor. But one time it did damage a wood floor a bit and I fear that one of these times it will break the vacuum. Each time I put it on, I tighten the straps. They slip that much. Everytime I lean over, they slip a bit. The light weight is nice, but overall, the vac just doesn't feel all that well built. The extension tube and attachments are too light weight, don't fit great and come apart frequently. The plastic fit and finish of the vac itself is not up to par and the harness is terrible. There is mold flashing on some edges. On the other hand, battery powered is wonderful and this unit is more powerful than any other cordless I could find. I use it in areas where a cord is impractical. So I am glad I bought it and I would do so again. And if battery powered is very important to you, I'd recommend it. But I will also keep looking. I have some EGO battery operated yard tools that rival even gas powered ones. They toast 110V tools. And their quality is excellent. If I could get EGO's technology and quality in a vacuum cleaner with a true power head, I'd buy it in an instant. I understand the run time might be less so I'd want two batteries. But it would be very small price to pay for a better unit.
