My mother told me to clean the room.
Literal
Mother [topic-は] me [to-に] room [object-を] clean [indirect-command-ように] said
部屋を掃除するように言った = standard indirect command pattern: 'told (me) to clean.' Softer than 言いつける ('to assign as a chore') — same instruction, but ~ように言う lets the speaker frame it as a request rather than a top-down assignment.
