Cordless or corded right angle drill for carpet brush?

[Troda]

Was looking at rotary carpet brushes. I put it out on the forum and most said drill mount. Now I’m curious what the general consensus is regarding
corded vs cordless RA drills. Bonus points (for me)if you recommend a brand.

My ryobi right angle just died. For what I paid, I got my money's worth...
The right angle is definitely worth it IMO.

I have the cordless m12. It works great and also makes a great tire scrubber

Plenty of right angle drill *adaptors* available w/o having to buy an entire drill.

looks like the variable speed is through the trigger. Any issues maintaining a constant speed?
