When the fluid level in the collection chamber contacts level sensor 54, level sensor 54 will generate an interrupt signal and send it to the main control board, thereby causing the floor cleaning apparatus to stop working, and at the same time, send a prompt to remind the user to clean the recovery tank 50.

In the present embodiment, the liquid level sensors 54 are two in number and correspond in position. Both level sensors 54 are level sensors 54 in the form of probes. The outside at two level sensor 54 all is established the cover and is equipped with sleeve pipe 57, and the bottom outside of sleeve pipe 57 is placed in to level sensor 54's sense terminal, and the top and the recycling bin upper cover 58 of sleeve pipe 57 are connected for two level sensor 54 place in the inside of collecting the room.

The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting of the invention. Those skilled in the art will appreciate that many variations, modifications, and equivalents may be made within the spirit and scope of the invention as defined in the appended claims.
