A cleaner includes: a suction motor that generates suction force; a suction unit that guides air and dust sucked by the suction force generated by the suction motor; a dust separation unit that separates dust from the air guided through the suction unit; a main PCB that generates control signals for the suction motor and includes a first PCB and a second PCB spaced apart from each other; a handle unit that receives the main PCB; and a PCB connector that connects the first PCB and the second PCB to each other and is coupled to the handle unit.
