TeamCity Cleanup runs weekly not daily

After repeatedly needing to run cleanup manually to reclaim disk space on out TeamCity server I notice that full cleanup is not happening daily as I thought it would but weekly. I manually ran a cleanup today because the disk partition was getting dangerously close to filling.

From a recent cleanup log:

Is this expected behavior? If so, how can I make it run daily?

Thanks,
