I just put a Cyclone XL unit into operation and I'm pleased with the boot, suction hose, motor/blower unit and hardware pieces...but...the container is a royal pain. Velcro has no place in dusty dirty applications and the vent/filter is continually getting plugged. Cyclone moulded in a pressure blow off outlet on the chute that feeds into the leaf container and I'm sure they did this because they knew the thing would plug the screen often. Last year I purchased the DR premiere unit w/the Subaru/Robin engine but sent it back. Without question I now know DR has the superior container. Hard sides, easy to open and their seperator on top is the best I've seen...but...the rest of the DR product was lacking compared to the Cyclone deluxe XL unit. (Heavy, tippy, smaller hoses, etc.) I'd rather keep the Cyclone unit and mount a DR container on the cart. This would be the best of both worlds...but...DR will not sell me parts unless I own a DR lawn vac. I was dumbfounded a company would not sell me parts unless I could verify ownership of a unit. They didn't even know why or what I wanted the parts for nor did they care. I'm in a quandry of what to do. I really like the Cyclone except for the cheesy fabric cart design but if I cannot come up with a solution this unit is going back to Cyclone this week. ( I pull the vac w/a Hustler ZTR.) Trac Vac has what I think is the best idea by mounting the blower directly to the tractor while pulling the cart like a trailer however their products appear to be of a lower overall quality. Anybody please jump in here and give me your two cents worth please. David.
