    4000 psi Pressure washer

    Posted by Dave on 7th Sep 2016

    This pressure washer has plenty of grunt, gets the job done. However the first time I used it the nozzle connection broke and water started to spray out of the bearings which left me with no pressure at all. Hoping to have this sorted ASAP.

    I was searching for a Pressure washer for cleaning the patio, car, etc. when my friend recommended me a Blue Diamond washer. He was so happy with the products performance that I could not resist myself from buying the same.
