A wellbore cleaning tool having a plurality of fluid jets arranged on one side of a tool body and brushes or other implements for applying an abrasion force arranged on a second side of the tool body. In operation, the fluid jets, when turned on, bias the tool body and the supported brushes toward the casing wall with a resilient jet-biasing effect. Furthermore, the tool body is intended to be rotated. Thereby, the resilient jet-biasing effect rotates accordingly so that the brushes remain biased toward the casing wall during rotation.
