I currently own a Volt Powernozzle-Love the thing-It inspired me to buy a Simplicity Freedom Cordless machine.When I got the new machine home tried listening and feeling the discharged air from both the Volt and the Freedom.The Freedom was much more powerful.So----I visited the vac place and asked Mike to order the more powerful motor like the new Simplicity has.Got it a week later-Mike and I put it in my Volt.Tried it--and WOW!!!makes a difference.Makes a great thing even BETTER!For the experts --are the new motors going to be used in the future Volt nozzles-The run time is slightly less-but better performance!
