Just thinking about buying a Numatics Henry Vacuum Cleaner. Can anyone tell me if there is any difference between the red one and the green one - except the colour of course! - every website I look at gives them a different power - either 1000W, 1100W or 1200W. It is just the basic Henry HV200 I am considering . Are you happy with him - or are you sick of his smug little face!!!???
