The working method of the mobile smart housekeeper based on the Internet of Things, including two symmetrically arranged brush plates (3), the left brush plate (301) and the right brush plate (302); and two symmetrically arranged direction control mechanisms (4), the left direction control mechanism (401) and the right direction control mechanism (402), are characterized in that: The walking drive mechanism (2) drives the main body (1) to go straight, the two brush plates (3) rotate in opposite directions or opposite directions, the cleaning liquid nozzle (34) sprays the cleaning liquid foam, and passes through the two brush plates (3) The bristle (33) cleans the ground, and sucks the sewage through the multi-circle circular bristle circle (32) and the dust suction port (31), and the sewage remaining on the ground is wiped clean under the rotation of the roller type brush mechanism (5), and finally passed Dry the hot air in the air outlet (6) to dry the ground; When any load-bearing sensing device (42) in the left direction control mechanism (401) or the right direction control mechanism (402) cooperates with the spring return device, the detected bearing capacity is gradually becoming smaller, and the walking drive mechanism (2) slow down; If the load-bearing sensing device (42) in the left side direction control mechanism (401) first detects no bearing capacity, the walking drive mechanism (2) stops driving, and the left side direction control mechanism (401) and the right side direction control mechanism The steering drive (41) of (402) rotates rightward at the same time, and the brush plate (301) on the left side and the brush plate (302) on the right side simultaneously turn to the right to assist the rotation steering; until the left direction control mechanism (401) The bearing capacity re-detected by the load-bearing sensing device (42), the drive of the walking drive mechanism (2) gradually increases from small to large; If the load-bearing sensing device (42) of the right direction control mechanism (402) first detects no bearing capacity, the walking drive mechanism (2) stops driving again, and the left direction control mechanism (401) and the right direction control The steering drive device (41) of the mechanism (402) rotates rightward at the same time, and the left side brush plate (301) and the right side brush plate (302) simultaneously turn rightward to assist and rotate the steering; until the right direction control mechanism (402) The load-bearing capacity detected by the load-bearing sensing device (42) again, the drive of the walking drive mechanism (2) gradually increases from small to large; If the load-bearing sensing device (42) in the left direction control mechanism (401) and the load-bearing sensing device (42) of the right direction control mechanism (402) cannot detect the bearing capacity at the same time, the walking drive mechanism (2) and the roller After the axial brush mechanism (5) reversely rotates and walks to set the displacement, the steering drive devices (41) of the left direction control mechanism (401) and the right direction control mechanism (402) rotate 90 degrees left or right at the same time. -180°, and the left or right brush plate (301) and the right brush plate (302) are assisted to rotate and steer to 90-180° at the same time; If the displacement detection unit and the clock unit detect that the displacement within the set time is lower than the set minimum value, after the travel drive mechanism (2) and the roller brush mechanism (5) reversely rotate and walk to set the displacement, the left The steering drive device (41) of the side direction control mechanism (401) and the right side direction control mechanism (402) rotates 90-180° to the left or right at the same time, and the left side brush plate (301) and the right side brush plate (302) turn to 90-180 ° with left or right power assist rotation simultaneously.
