1986年，美国Annovi Reverberi公司生产出全球首台压力100Bar便携式高压清洗机，随后开始量产电动高压Car wash machine。2006年了AR集团旗下的清洗机品牌DE Blue Clean正式创立，并在欧美逐步打开市场，为北美知名的汽车工具生产商B&D和Michelin提供ODM服务。2016年DE Blue Clean进军中国大陆市场。
 
DE Blue Clean has a small number of home car washes, but the difference in performance and pricing is significant. From 118 yuan for 500 yuan to 491 yuan for 2600 yuan, DE Blue Clean has launched products with power from 1300 to 2100W, and consumers can easily find the corresponding products according to their needs.
 
A wide range of accessories, good quality, and high price are another major feature of the DE Blue Clean car wash. In addition to the general gun barrel, sprinkler head, and brush, DE Blue Clean products also have through-hole pins, grease, floor brushes, wheel brushes, car wash gloves and other accessories, which are of guaranteed quality, but most of them are not listed in the standard equipment and need to be purchased separately. If you choose the full version when you buy it, the price will often be 20% to 40% higher than the standard version.
 
Similar to karcher, DE Blue Clean's 100 yuan product is not as cost-effective as Chinese brands, so the most recommended model within the brand is the 360 model, which is priced at 1,000 yuan. This model includes a 3-in-1 nozzle, a long-bristle brush, a foam pot, a self-priming unit and other accessories as standard. In addition, the 10M water inlet pipe that comes with this model is twice as long as that of low-end products of the same brand, giving users more space for activities. In terms of power, the 360 has 1600W of power and can discharge up to 120Bar of pressure, which can meet most car wash needs. In terms of safety, the 360 is equipped with a shut-off stop and safety lock key design to avoid accidental touches and save energy.
 
For consumers who need more cleaning power, it is recommended to choose the 380 with 1800W and 135 bar pressure instead of the 491 with 2100W and 145 Bar. The 380 comes with three injection modes: fan, rotary and foam, and with the included extended barrel, it can deeply clean all parts of the body. The storage slots for each part are hidden in the housing, so that users can place the parts in a neat and convenient way. Although the 491 upgrades the 380's 3-in-1 nozzle to two metal booms, the difference between the two is not much for the average user. As far as users who wash their cars once a week are concerned, 380 is completely sufficient, plus 1000 yuan to choose 491, which is not cost-effective, is of little significance.
 
Some people pointed out that the DE Blue Clean car wash machine is easy to idle in self-priming mode, and the nozzle does not produce water, which is actually a problem with all car washes with self-priming mode. Since the water source from the tank does not have its own water pressure (about 5 bar) like tap water, the water dispensing speed is slower. Before use, the nozzle can be removed, and the nozzle can be installed after the barrel drains the air. Shortening the distance between the water tank and the car wash machine and adjusting the height of the water tank can help solve this problem.
