I recently purchased the Wilks-USA RX525 High Powered Pressure Jetwash. I did not know exactly which one to buy at the time but when l called Union Mart Customer services Dept., they were extremely helpful. Asking me exactly what my needs were, and what sort of areas l needed to clean. I was quite worried before speaking to them as l had previously bought a Jet wash for another retailer and it just was not powerful enough and it ended up in my shed for years and was a total waste of money. I liked the fact that they did not mind me asking several questions about the attachments/power etc., The gentleman l spoke to went over and beyond his help. Well Done Union Mart!!!! Great customer service.
