[0002] The wet and dry portable vacuum cleaner dissolves and locks dust, garbage, bacteria and other microorganisms in the water when they are sucked through the water tank by strong suction. The dust is wetted by water to prevent the spillage of fine dust during vacuuming. The inhaled gas is purified by water to dissolve allergens, bacteria and other microorganisms. Then, it is further filtered through HEPA and high-efficiency filter cotton. These three purification systems ensure perfect and efficient water filtration.

[0003] The wet and dry portable vacuum cleaner can remove dust and small debris on the ground through the suction force generated by the high-speed fan, but the dust or dirt adhering to the ground cannot be cleaned thoroughly, which limits the use of the wet and dry portable vacuum cleaner.

[0004] Combining the above-mentioned problems, it is found that it is difficult to avoid the above-mentioned problems when the existing devices on the market are in use, and thus it is impossible to achieve the desired effect. Therefore, we propose a wet and dry dual-purpose lightweight vacuum cleaner which can remove stubborn adhered dust and dirt during use and improve the cleaning effect. Summary of the invention
