The complaint was filed against him by a 47-year old Saudi translator, Khaleej Times reported.
A Saudi translator, who complained about the incident said she had seen the worker watching her from behind the cubicle's concrete wall.
The worker sneaked into a ladies' washroom in a mosque and watched the woman using the facility.
The accused has been ordered to be deported by the Court of First Instance.
He claimed in the public prosecution investigation to have entered the washroom to clean its walls and ventilation fan.
"I passed by the accused and saw him watering the plants in the yard. Shortly after I entered the cubicle, I smelt an odour...of sweat. It lasted for four to five minutes," woman said.
The accused fled the scene when she screamed.
"He is allowed to do the cleaning work...(at a specific time)...after making sure it is vacant. It is a very small place and he could easily know if anybody is using it," worker's Iraqi supervisor said.
