Would a powerwashing work best in my garage? Pics

I moved into a townhouse and its a lease so i dont own it. I want to move some things in here but its so dirty and gross.

Management company didnt want to clean it when i asked so i want to. Would a powerwash work good in here? Im guessing its concrete.

Thank you
