iLonda Aquarium Electric Gravel Cleaner (Battery Operated)

Maybe i m still learning how to use it

though having a newly bought battery, it didnt have enough power to **** up dirts at the end of the cleaner/pipe, water and dirts can only be suction in on near to the blue handle ie near the filger bag, hence it is not very useful to extend the cleaner longer....be prepared to submerged your hands totally into water if you wish to use this On the packaging, it listed a usb cable but i do not find the cable in the box at all, hence we cannot use electricity to operate...
