I will soon be looking for a new machine, likely contenders are the Jag the Storm or the Enforcer,
if the enforcer had its vacs set in parallel I wouldn't have any hesitation, but having used a tripple now or two for the last eight years that are parallel, that is my prefered choice, I had three ninjas, the last with a booster adaption fitted but it diddnt clean nor leave carpets as dry as three motors in parallel as per my Scorpys
