Bought my Narwal freo x ultra and the detergent has been sold out since day 1. It’s been 4 months now and it’s frustrating I bought a product that I could use half of the function due to lack of supply from Narwal. It says on the manual if you use any other products, it voids the warranty. When I called customer service to see if they can do anything, they acknowledged the problem but could not do anything. My biggest worry is I’d like to give it a try with the mop to see if my product is working fine before warranty runs out as this is not a cheap product to purchase
