PROBLEM TO BE SOLVED: To provide a cleaner equipped with a roller adjusting device. SOLUTION: The cleaner comprises an upper lid of a main body, a main body base and the roller adjusting device, which comprises a presser mechanism, a braking mechanism and a roller. The presser mechanism has a locked part, and the braking mechanism has a lock part for locking the locked part. The roller is assembled in a wheel shaft, and the wheel shaft is pressed as the presser mechanism is pressed so that the locked part of the presser mechanism and the lock part of the braking mechanism are engaged with each other, and then, the cleaner is raised by the roller adjusting device. When the braking mechanism is pressed, the lock part of the presser mechanism and the locked part of the braking mechanism are disengaged from each other, and the cleaner is lowered to return to the original state.
