However, there are some drawbacks to the CR Spotless system. For starters, many airports in drought-stricken areas no longer allow for washing stations that use water. Also, at 50 pounds, the DIC-20 is cumbersome to lift, so if you have to lug it back and forth to the airport, a smaller system would be recommended. CR Spotless offers several sizes. The DIC-20 costs $449.99 and includes everything you need, except a hose and cleaning products.
