Has anyone got the NUMATIC HENRY HVR200A ECO BAGGED VAC CLEANER?

I bought one today but didnt realise it was ECO friendly. The thing is im ok with that but does that mean i cant use normal Henry dustbags cos they can be cheap. The leaflet suggests to use a NUMATIC HEPA-FLO dustbag...im confused. I would like to use the normal henry bags but would that spoil my henry???
