Hi any advice would be appreciated. I am looking to purchase a new jet wash, for the last 5 months ive been using a wilks tx750 and it has served me very well but needing something to use a surface cleaner 21 inch. As i found out today the wilks could not power one of these and left me with a problem on my next job. I have a budget of £1000 - £1200 and been looking at the kiam 3700 15 litre per min for £750 but been reading a couple of bad reviews on the kiam products has anyone used one of these machines and what would be the best equivalent in the price range if kiam is best to be avoided. Just want a machine to speed up cleaning times and use a surface cleaner to save my back and shoulders for the next 6-8 months untill i can get the slipsream pro 20 next year. Thanks in advance
