Roborock in Saudi Arabia - Alternative cleaning solution

So, I just bought an S8 MaxV Ultra for an amazing discounted price with Ramadan offers (and other multiple offers based on the payment method 😅), and it is my first experience with such machines! And boy, it is satisfying and totally worth it. However, I ran into an issue of finding the cleaning solution), it is soooooo expensive, in my opinion; compared to the original price.
