Disclosed are an air purifier and control method for purifying air; the air purifier comprises a main body (1), a control unit (4), a moving unit (2), an air purifying unit (3) and a sensing unit (5), wherein the control unit (4), the moving unit (2) and the air purifying unit (3) are located inside the main body (1); the sensing unit (5) comprises an obstacle detecting sub-unit (51) and an air pollution detecting sub-unit (52), respectively connected to the control unit (4). The control method comprises the steps of: step 1, moving the air purifier along the edge of the space to be purified, detecting the degree of air pollution in real time while purifying air; step 2, the air purifier searching for the source of pollution and purifying the air where the source of pollution has been found when the air pollution value detected is more than a first predetermined value; step 3, moving the air purifier in a first predetermined travelling manner when the air pollution value detected is less than a second predetermined value; and step 4, returning to step 1 when the air purifier achieves the predetermined requirements while moving in the first predetermined travelling manner, or else continuing to move in the first predetermined travelling manner. |
