Write a method in the controller and call it in the VF page using a command button. Inside the method use the below code 
public void callBatch()
{
 CleanUpRecords c = new CleanUpRecords(query);
 Database.executeBatch(c);
}

Please check below post for sample code.

You can also use action poller to see the status of batch job.

Action Poller:-
Supporse you need to execute one Apex batch job from Visaul force page and need to show the status of Apex batch job on visual force page.
In that case you can use ActionPoller to refresh the seaction to show Batch job updated status.
Main Use or Action Poller is to refersh the VF page section. A timer that sends an AJAX request to the server according to a time interval that you specify
This tag specifies a timer that sends an AJAX update request at specified interval. Minimum interval time to refresh is 5 sec.

Yes.  Your Visualforce page will need either a custom controller or an extension class.  From that class you can use the Database.executeBatch method to kick off the asynchronous method.
