I just bought a new Moen kitchen faucet, which looks great. I didn't pay attention at the time of purchase, but I noticed there are no screws on the faucet handles for removal like on older faucet handles. After looking at some pictures of modern faucets on the internet, it appears no others do either. Do modern faucets not require new washers or stem cartridges on occasion, or is there another way to remove the handles?
