When using over and over it helps you get a better understanding of the T.S.P. and forces you to run a more efficient route.
This site will occasionally glitch or hiccup and throw out a bad route even when data is input correctly.
Always double check the route any software suggests.
I have not had time to get a detailed year to date comparison from this year to last but feel confident we have saved on average as much as 15 minutes per day and shaved off on average 7 miles per day. It adds up.
Mapquest will let you enter in multiple stops. It will then configure them for most efficient route. I haven’t used it for window cleaning, but I did use it when planning a road trip the summer before last. I entered all the weird roadside attractions I wanted to see and it plotted a route for me.
