To provide a toilet device that ensures crushing operation suitable for amount and state of a processing object.

A toilet device 100 allows a crushing mechanism 2 to detect a load of a crushing motor 20F that drives a rotating crushing cutter 2C. When it is determined that the crushing motor 20F cannot rotate normally based on the load, a re-try operation is performed by reversing the rotating direction. When the re-try operation fails to have a normal rotation, the operation is stopped. When it is determined that the crushing motor 20F has been locked based on the load, the operation is stopped without performing the re-try operation. Control for optimizing the operation is further executed based on the load.
