When the robot vacuum cleaner is located on a horizontal ground, the universal wheel and the two drive wheels contact the ground, and the support part is spaced from the ground by a preset value. When the robot vacuum cleaner is inclined towards a side where the water tank assembly is, the support part contacts the ground.
