Smart floor cleaning device and control method for the smart floor cleaning device

A smart floor cleaning device, comprising:

• a body, a chassis, a processor, a negative pressure source, and a sewage tank installed on the body, wherein the negative pressure source is connected to the sewage tank and configured to apply a negative pressure to draw sewage during a cleaning process into the sewage tank;
• the smart floor cleaning device further comprising an angle detection device,
• wherein the body is rotatably connected to the chassis, the processor is installed on the body or the chassis, and the body is configured to rotate around a first axis and a second axis;
• the angle detection device is installed on at least one of the body and the chassis,
• wherein the processor is electrically connected to the angle detection device and configured to obtain the rotation angle of the body rotating around each of the first axis and the second axis or around the second axis based on a detection signal of the angle detection device;
• wherein the negative pressure source is electrically connected to the processor, and the processor is further configured to control an output power of the negative pressure source based on the rotation angle;
• wherein the first axis and the second axis are perpendicular to each other.
