Abstract
Method and device for collecting objects pointing out of the bottom level of seas or corresponding water areas so that the objects are carried from the bottom by using waterflow through an intake opening of the collecting device moving on the bottom of the sea. The objects are removed from the bottom by a removing device. The lowermost part of the removing device moves at the same level with the bottom of the water area or above it. The most suitable way of removing the objects from the bottom is by using water spray, the flow power of which is controlled separately from the flow power of the water in the conveying channel.
