A small robot cleaner is provided to collect foreign matters from a floor by installing a pressure unit contacting a dust collecting pad on the floor, to move the small robot cleaner over an obstacle by projecting a wheel of a driving unit in certain length or above, and to selectively clean the floor by improving driving force and using a wet dustcloth instead of the dust collecting pad. A small robot cleaner comprises a cleaner body(10), a driving unit(20) installed in the cleaner body, a dust collecting pad(30) installed in a lower part of the cleaner body to collect foreign matters from a floor in moving the cleaner body, and a pressure unit(40) mounted between the cleaner body and the dust collecting pad to press and slide the dust collecting pad on the floor. Plural storage parts(12) are formed in a lower rear part of the cleaner body to move the pressure unit in and out.
