This application provides a filter cleaning system, a filter cleaning method, and a data center. The filter cleaning system includes a first filter, a first-stage cleaning unit, a sensing unit, a control unit, and a second-stage cleaning unit. The first-stage cleaning unit includes at least one of an adsorption assembly, a washing assembly, or a brush assembly. The second-stage cleaning unit includes a motor and a mandrel assembly that includes a second filter, and is configured to replace at least one part of the first filter with a part of the second filter. The control unit is configured to control, based on a pressure parameter that is of two sides of the first filter and that is obtained by the sensing unit, the first-stage cleaning unit and/or the second-stage cleaning unit to work.
