A question for those condemning velcro treads (from someone who's never used them): Are you sure velcro will damage the carpet? I am under the impression that velcro releases by
uncoiling the plastic hooks not tearing the loops (if it tore the loops, it wouldn't be very reusable would it?) Even if the velcro tore away some of the loose fuzz, I can't imagine it would be much worse than the reams of carpet remnants we dug out of our (KOP-wheeled) bot this year!
MamaSpoldi - that's incredible! I don't understand how any thoughtful judge could rule that a rubber pad were any different than a stationary rubber wheel.
