The stackable structure of the top of the main body 10 and the bottom of the base 30 is designed to facilitate the stacking of wet and dry vacuum cleaners, facilitate storage and carrying, and reduce storage space. The reasonable layout of the vacuum generator 101, the filter 102 and the battery pack 103 ensures the efficient operation of the cleaning device. The design of the dust collection port 13 makes it more convenient to connect the dust collection hose, and it is arranged on the same side as the opening 311, which is convenient for user operation. The vacuum generator 101 and the battery pack 103 are arranged side by side along the left and right sides, which not only saves space but also maintains the balance and stability of the entire cleaning device.

[0039] Among them, the base 30 is provided with a first support portion 331 and a second support portion 332 spaced apart along the moving path, the first support portion 331 and the second support portion 332 have different heights in the vertical direction, the bottom surface of the dust bucket 20 is respectively matched with the first support portion 331 and the second support portion 332 in shape, and the first support portion 331 and the second support portion 332 are connected by an inclined transition surface 333. The inclined transition surface 333 can enable the dust bucket 20 to achieve a smooth transition during the movement process, avoid sudden falling, thereby protecting the structural integrity of the dust bucket 20 and reducing noise. The bottom surface of the dust bucket 20 is matched with the shape of the support portion to ensure the stability of the dust bucket 20 when moving and fixing. The inclined transition surface 333 can be a smooth transition surface such as an inclined surface and an arc surface. The first support portion 331 and the second support portion 332 are connected by the inclined transition surface 333, which further optimizes the moving path of the dust bucket 20 and makes it move more smoothly.

[0040] In addition, accessory boxes 40 are respectively arranged on both sides of the base 30, the accommodating chamber 31 is defined by the base 30 and the accessory boxes 40 on both sides, and the guide rails 32 are arranged on the accessory boxes 40 on both sides. These accessory boxes 40 can not only be used to store various cleaning tools and accessories, but also play a role in supporting and stabilizing the dust bucket 20. The accommodating chamber 31 is defined by the base 30 and the accessory boxes 40 on both sides, ensuring the stability of the dust bucket 20 during use and movement. The guide rails 32 are arranged on the accessory boxes 40 on both sides, so that the pulling and positioning of the dust bucket 20 are more stable and accurate, and the convenience and safety of operation are improved. The wet and dry vacuum cleaner of this embodiment not only realizes the convenient separation and cleaning of the dust bucket 20, but also provides additional storage space and better stability, thereby improving the user experience.
