Wait, can you explain this? What pads have velcro?
All the pads I've purchased are for hand application, and that machine takes bonnets/shower cap like pads. I know I've seen a separate large pad with the clay in the middle, need to look into it more as I don't know the drive on this machine or what the soft rotating component can be replaced with.
I honestly don't even know why they call it a polisher. I haven't even used it yet but I'm assuming it's soft/not so abrasive as those Rupes and other polishers are. If it is I'll have to be extra careful applying everything, which would probably also defeat the purpose of doing it faster than hand application.
The Rupes or griots garage dual action polishers are not abrasive like you say they are. It all depends on which pads you use. There are pads for removing swirls/scratches from light to heavy and there are pads used to apply waxes and sealants.
This chart breaks down the different types of pads and what they're used for. Each manufacture has their own coloring scheme which refers to a different type of cut and all these pads have velcro on the back which is used to attach to the backing plate of your Rupes or Griots garage.

Pads are sold in various sizes from 3 inches all the way up to 8.5 inches. Optimum size is usually a 5 inch backing plate with a 5.5 or 6 inch pad. There are also flat pads and pads with grooves on them that distribute the product better.

BTW autogeek.net is a great place to get detailing supplies, that's where I get all my stuff from. And you'll also need some apc or a pad cleaner to get that product out once you're done with it.
If you look at this video you can see the velcro part at the 0:38 mark and he puts it on his Rupes at the 1:07 mark.
I'm not sure where you got those covers from but I'd invest in actual pads and DA polisher if I were you. You don't need to drop a ton of money on a Rupes just get yourself a Griots garage random orbital with a 5 inch backing plate and 5.5 or 6 inch pads. Just get the right pads for the right job. Rupes are made mainly for the pros. And always remember less is MORE. I put a ton of sealant on my pads and by the time I was done I wan ringing out so much sealant from the pad that I could've done another entire pass across the car. The sealant stays in the pad so just push down onto the paint to get it out. Hope this clears things up
