I have not tried the original at all.
I have had a short time, say 15 min, using the 360 and I would need more time to get used to it but certainly would not dismiss it at this stage.
Have you been on You Tube, type in rotovac 360.
Very impressive video cleaning a red carpet in a Chinese restaurant in the UK.
Early models did have a power problem due to the switch from US to UK market but I understand that has been sorted now.
I know Goron Knight has one and Dave Ingram, but Daves I believe is a 115v and he uses a transformer.
Hope this helps.
