Your original post uses find -print0 and xargs -0. Is your customer using a GNU userland? If not, those extensions are probably not supported. If they are using a GNU userland and if that's all that needs to be supported, then Don Cragun already gave you the answer.

The + terminator for find -exec is not a GNU userland extension; it has been required by the standards since 1991.
Note, however, that the command I suggested only removes the regular files; not empty directories. The original code in the OP's script:
which would more efficiently be written as:
attempts to remove directories and all of their contents and then to remove some of the files in those directories after they have already been removed while removing their parent directory recursively. Furthermore, if a directory hasn't changed in a day, but files in one or more of it subdirectories changed in the last hour, those directories and the new files in them will also be removed.
A safer way to do it would be a two step process: remove the old regular files in the 1st step and then remove old directories in the 2nd step:
Using rmdir instead of rm -r guarantees that you won't remove new files accidentally, but you might get error messages trying to remove directories that aren't empty. If that is a concern, you could redirect stderr from the 2nd find. This method will keep directories that have been emptied by the 1st find around for an extra day (since the directory timestamps will be updated when the regular files in them are removed), but they will be cleaned up one day later if they are then empty.

That's an indication that find is not passing any findings to xargs to execute.

No, it isn't. If no filenames were passed through the pipe to xargs, xargs should not exec rm. Something else is going on here, but it isn't clear to me what.
