Duct Cleaning Systems

Which type of air duct cleaning system is better? ?
Which type of air duct cleaning system is better, the type like a Rotobrush where you stick a vacuum with a brush inside and clean the ducts that way. There’s also another system where it uses negative air pressure to blow all the debris to one area where you can clean it out.
A buddy of mine is looking to start doing this service so I’m asking this for him. He’s looking at the Rotobrush and the Nikro System.

My buddy is looknig to buy one of these systems. The people trying to sell to him both say theirs is better and have compalints about the other system of course. Can you offer some advice. Which cleans better? Which is easier to use? etc.
Rotobrush has had several issues since its inception. Most good duct cleaning companies I know refuse to use it.
