The restriction in airflow makes it feel uncomfortable to use, it feels like you using a clogged purepower and that clogged feeling is very dissatisfying!
However it is still better than the DC01 and with wider air paths it could be as good as a Purepower in terms of strong suction at the cleaner head like a Purepower has.
It boggles the mind as to why Hoover didn't realise this!!
