My DC14 origin lifts the floors like this because I put seals in the soleplate. They normally don't have it. BTW The newer soleplates are specially designed to be easy to push and still do a good job. My DC14 is an older version from around 2005 I think.
If your DC07 Origin was easy to push then the DC14 should be the same. The clutched version has the large debris channel and edge cleaning in addition so it's much easier to push and you still have good performance (not as powerful as the origin tho)
