Ladies and Gents, I have been skeptical about carpet protectors, but I know we can generate a substantial amount of additional revenue with it. My skepticism regards how long it actually lasts, considering the abrasiveness of vacuum beater brushes. Doesn't the beater brush cut through and eventually remove the protector? I imagine a client who faithfully vacuums weekly, and after 20 or 30 vacuuming, perhaps far sooner, wouldn't the protector be gone? Please help me understand this a little better. I want to be sure it is truly a benefit to our customers and not just a sales gimmick, for lack of better words. Thanks for your input.
