We moved into our house shortly after the previous owners installed this faucet:
We've had it for about 5 years now and the water flow is severely limited. Also, it takes forever for the hot water, but when I remove the faucet head it seems normal. I was just going to replace the faucet head, but a new one is $200. There's no instructions or documentation for the faucet, so I don't know if I'm supposed to be cleaning out the faucet head.
Can somebody either advise what I can do, or tell me where I can find some documentation online? I checked Grohe's site but I can't find this specific model.

Try removing, disassembling (take notes!), and soaking the faucet head in a mix of hot water and vinegar (50/50) for a short while (e.g. an hour or two), to help remove any tap water mineral deposits that may have made their way into the head of your faucet and that are restricting your water flow.
Faucet heads typically have very fine passages and/or aerator mesh, and it's not uncommon for a build-up of tap water mineral deposits to cause water flow problem over time. I've experienced this first hand, and a good vinegar soak did the trick.
Best of luck.
