Abstract
A liquid vacuuming device for drawing off and vacuuming up liquids may include a housing (), an extractor device formed by at least one extracting lip () for extracting and collecting the liquid in front of at least one vacuum mouth (), a vacuuming device that features a motor-driven vacuum subassembly and is able to vacuum an air/liquid flow mixed with the liquid to be vacuumed up along a flow pathway from the vacuum mouth () through an intake channel () into the housing (), a separating device () for separating the liquid from the air and a tank for receiving the separated liquid. The device may further include an on/off function that turns on the motorized drive or increases the motor power when pressure is exerted upon the extracting lip () and turns off the motorized drive or reduces the motor power when the pressure decreases. Similar functionality may be implemented by an orientation switch.
