Remotely activated multi-cycle wellbore cleaning tool

A method comprising:

• deploying a workstring into a wellbore, the workstring including a cleaning tool disposed thereon, the cleaning tool comprising:
• a tool body having an upper inner mandrel, a scraper body, a bypass opening and a flow path for a flow of liquid through the tool body;
• at least one scraper blade positioned on the scraper body;
• a first magnet disposed on a first surface of the cleaning tool;
• and
• a second magnet disposed on a second surface of the cleaning tool, wherein the at least one scraper blade is deployed in a retracted position and configured to move from the retracted position to a radially expanded position outward to a wall of the wellbore based on movement of the first magnet relative to the second magnet,
• wherein the upper inner mandrel includes an internal bypass positioned uphole of the scraper body, wherein the bypass opening and the internal bypass align when the at least one scraper blade is in the radially expanded position, enabling fluid flow between the wellbore annulus and the flow path uphole of the at least one scraper blade;
• positioning the cleaning tool at a cleaning depth;
• and
• in response to the workstring being positioned at a cleaning depth,
• controlling a flow of liquid through the flow path;
• and
• moving the at least one scraper blade from the retracted position to a radially expanded position in response to controlling the flow of liquid through the flow path of the cleaning tool.
