I am using ESS Beta1 and I find the when in Windows Explorer, when I start a on-demand scan by right-click on object and selecting "Scan with Eset Smart Security". The on-demand scan never cleans any infection it finds. If cleaning is required, you have to right-click > Advanced Options > Clean files. I think the latter is kind of redundant. Since cleaning can be done in the first option itself. Most people would like their on-demand scan to remove any threats it can also. So, IMO it would be best if you integrated cleaning into the on-demand scan by default. And give the option of scan without cleaning in Advanced Option. Instead of the opposite, currently in the beta.
