Reviewer 1 Report
This manuscript considers theoretically the formation of dust-acoustic rogue waves in an electron depleted unmagnetised dusty plasma. The results can be of some interest to better understand rogue waves in diverse dusty plasma systems. The topic of this manuscript is appropriate for Plasma. The manuscript is relatively well written. Illustrations are appropriate. In the abstract the authors claim that the formation of these rogue waves “is theoretically observed for the first time.” I think writing “theoretically investigated” or “theoretically predicted” would be more appropriate. Apart from this I do not see any serious flaws and can recommend this manuscript for publication in essentially current form.

Reviewer 2 Report
The authors have written a theoretical article about dust acoustic rogue waves in dusty unmagnetized dusty plasmas containing positively and negatively charged grains. By using third order expansion of the electrostatic potential, they obtained the non-linear Schrodinger equation of the DARWs. They were able to study the influence of the dust grain number density and the charge state on the rogue waves.
While the results look correct, as the author mention in the introduction paragraph, the presented work is an extension of the work of Ref. [1]. Moreover, most of the reference refers to theoretical paper with very little citations referring to experimental observations. Finally most of the cited articles in the introduction are also theoretical article mentioning possible applications of opposite polarity dusty plasmas but not devoted to studies of OPDP within this specific applications.
I would therefore suggest the authors to improve their article by discussing why their result is a major improvement to the dozens of theoretical paper dealing with rogue waves in dusty plasma and how their results could be of use to experimental plasma physicists.
