Even if a very small portion of the dirty liquid splashes into the vents 425, the kinetic energy of the dirty liquid is depleted during the ascent and does not flow into the dirty fan 410.
Referring to fig. 9, when the body 200 is in the lying state, the roller 530 contacts the surface to be cleaned and forces the trigger portion 511 to drive the shielding portion 512 to move toward the body 200 to abut against the positioning plate 4211, at this time, an included angle α2 is formed between the body 200 and the surface to be cleaned, and the included angle α2 may be set to be 0 °,3 °,5 °, 7 °,10 °,12 °,15 °,17 °,20 ° or other reasonable dimensions. The handle 600 can be kept upright when the body 200 is in a reclined state, facilitating the user's handling of the device through the handle 600.
