Has anyone here owned a Lotus Mermaid 180, how does it work?
Here is a video:

The door step of the entrance is flooded, need to empty the water asap:

but the pump seemed to be not working properly, when power applied to the motor pump it did turn but with some strange noise, sounded like the rotor is not tightly secured, the above video link was a test to see if it can suck water out, no water out at all....Does the pump has to be submersible in order to work?

thanks,

 

Welcome to the forums.

If the pump didn't perform in your test..... it certainly won't be pumping anything out.
It could be defective right out of the box.

That seems to be a small, very low flow and low lift type of pump not particularly designed for what you are doing.

 

Hello Pjmax,
I had the pump returned, called a plumber to sort it out for us.

thanks,
