Virtual wall as the name suggests is a virtual wall, is not real, what we call the magnetic stripe virtual wall is actually a long thin magnetic stripe, the magnetic strip edge fixed in a certain area, can be like a Wall Street sweeper, blocking the street sweeper block in cleaning the outside of the area, without affecting the people through, the state is like "journey to the west" three strikes "the bones jing sun story gave him the master painting circles, tang's monk can free access to, and the devil is not.
The magnetic stripe virtual wall function is very practical, such as the bathroom and kitchen, can cut off the sweeper without closing the door.
For example, the general toilet will put a floor mat, the purpose is to take a bath will not be too wet on the ground, to avoid sliding, if the floor robot is not accidentally into the brush will be easily entangled.

So how does a magnetic stripe virtual wall work?
Sweeping robots are known to be fall-proof, with sensors that tell the machine to stop when it senses a step or suspension ahead.
And the virtual wall of magnetic stripe makes use of this working principle, which can absorb the inductive wave emitted by the machine to avoid the reflection that will sweep the robot, making the machine think that it is suspended and will not go forward.

The magnetic stripe virtual wall is cheap in price and has very powerful and practical functions.
