Having the right system accessories significantly increases the number of applications that are possible and make cleaning even more effective, time-saving and convenient. All of our industrial and commercial hire cleaning machines are maintained to the highest standards, so you can be assured of peak performance. For this test we concentrated on washers which would be on the shortlist of the average DIY car-cleaning enthusiast.
