It does what it claims. With one exception, It isn't able to remove red clay out even with a pretreatment. That being said, I haven't been able to find any laundry soap or pretreatment that will do it either. Haven't have any problems so far. Haven't had it but a month.
I followed instructions carefully and the unit leaked horribly. I am in discussions with the manufacturer to try to fix whatever is causing the issue. Perhaps plumbers tape might alleviate some of the leaking.
cancelled the order and you have since reimbursed me. I did not receive this product, but they are great as I have had one for years it finally broke down.
