Running powershell script for scheduled task is not that complex,you can create a powershell script and run schedule basis.the below script is for clearing the cache on a schedule basis, best practice is not to clear the cache often,it will effect to your site performance.

Basic script:

ForEach($site in [Sitecore.Configuration.Factory]::GetSiteNames()) {

    $siteInfo = [Sitecore.Configuration.Factory]::GetSiteInfo($site)

    if($siteInfo -ne $null) {

         $siteInfo.HtmlCache.Clear()  

         $logEntry = [string]::Format("mahe through Scheduled Task your HtmlCache.Clear() invoked for {0}", $siteInfo.Name)

         Write-Log $logEntry

         Write-Host $logEntry

    }

}

1)      Write above script in your powershell ISE and excute if it’s working fine save as [some name] PowerShellHtmlCacheClearTask
