Haskell en Clean are very much alike.
From what I could determine from a basic Clean introduction, Clean is very *unlike* Haskell, having a far more verbose and low-level syntax. (E.g., the compiler can't even determine whether a binding is recursive or not for itself. You have to say that manually.) It seems a very unecessarily complicated and messy language - which makes the name rather ironic.
You can even compile Haskell 98 code with the latest (experimental) Clean compiler and having it interact with Clean code and vice-versa [2]. The main difference is Clean's use of uniqueness typing.
As I say, I thought the main difference is that Clean is strict (which is why you can get good performance). Uniqueness typing is an interesting idea, that looks like it might be useful for more than mere I/O.
