         11 . The vacuum cleaner of the  claim 1 , wherein the suction pipe assembly is provided with a limiting member for limiting the dust accessory to have a preset circumferential position relative to the suction pipe assembly, and a light incident surface of the light guide member is directly opposite to the lighting element when the dust accessory is located at the preset circumferential position. 
     
     
         12 . The vacuum cleaner of the  claim 1 , wherein the remote controller is provided with an energy storage element for storing electrical energy, and the energy storage element is configured to supply the electrical energy to the lighting element. 
     
     
         13 . The vacuum cleaner of the  claim 12 , wherein the remote controller housing is provided with a charging interface configured to charge the energy storage element. 
     
     
         14 . The vacuum cleaner of the  claim 1 , wherein the remote controller further comprises a lighting switch for lighting the lighting element. 
     
     
         15 . The vacuum cleaner of the  claim 1 , wherein the dust accessory body is made of transparent or translucent material. 
     
     
         16 . An electric tool, comprising:
 a tool body comprising a housing assembly, an output member mounted to the housing assembly, and a motor for driving the output member to move;   a tool accessory detachably mounted to the tool body;   a remote controller configured to be operated by a user to control the operation of the tool body; and   a light guide member mounted to the tool body or the tool accessory;   wherein the remote controller comprises a remote controller housing and a lighting element mounted to the remote controller housing, the remote controller is detachably mounted to the tool body or the tool accessory, and the light guide member is configured to guide at least part of a light emitted by the lighting element when the remote controller is mounted to the tool body or the tool accessory.
