A float assembly that can generate its inflowing water current for collecting water surface debris in a water body. Float assembly can be mounted to a fixed structure at the water body and includes a basket supported by a pair of floats buoyant in water. The basket includes a pump housed in a perforated housing, wherein the pump can be operated to suck water through the inlet also carrying the debris into the basket. The debris of a suitable size can be retained in the basket while the water is pumped out through an outlet. The basket can be switched from an operating state i.e., submerged in water to a stowed state outside the water upon the fixed structure.
