point of order:

hover mowers are rotary mowers, the rotary blades spin on a shaft mounted
on a vertical axis to create the downdraught for the hover effect.

mowers with wheels and a roller tend to be cylinder mowers, with the
cylinder
mounted on a horizontal axis

I surrender !

Yes, OK, a rotary mower with wheels will collect better than a hover mower.
It is often a more practical option than a cylinder mower, although these
also collect well.
