Carwash customers value the convenience of having a powerful vacuum to
clean out the interiors of their cars. Carwash owners enjoy the
income from a low maintenance piece of equipment.
Features to look for...
2 motors vs. 3 motors. Many of the vacuum manufactures offer 2 and
3 motor options. The advantages of having a third motor include higher
suction. This can be important at higher altitudes but may not be noticeable
to the regular carwash customer. Also if the vacuum is remotely mounted
or uses a long length of hose the third motor may be a better choice.
Another reason to consider is if one of three motors is out, it is not
nearly as noticeable as one of two being out.
More filtration. Most of the vacuums offer four filter bags. This gives
a large total area of filtration to reduce the lose of suction to the
filter.
Hose.
2" hose is less likely to get plugged with debris than a 1½" hose.
