Route optimization for mowing is about shaving minutes off forty short stops. Pressure washing is the opposite problem. A truck might do three to six jobs in a day, each one taking an hour or several, and a single bad placement (a house wash on the far side of the county between two driveways in town) can cost more time than all the other drives combined. Routing washes is less about the perfect order of stops and more about which jobs share a day in the first place. This post covers how to group wash jobs, how to pair big and small ones, what else besides addresses belongs in the route, and how to put the day in order.
Decide Which Jobs Share a Day
With mowing, you have a fixed list of stops and you put them in order. With washing, you have a pile of approved jobs and you get to choose which ones go together. That choice matters more than the order.
Look at your approved jobs on a map before you look at a calendar. You will usually see natural clusters: three in one subdivision, two near the shopping center, a scattering in the next town. Build days around clusters. A day of three house washes within a mile of each other is far better than the same three spread across the service area, even if the total job hours are identical.
On the Waiting List you can circle an area on the map, pick the properties in it, and schedule them onto a day and truck in one step. That is the fastest way to turn a pile of approvals into sensible days. Jobs that do not belong to any cluster wait until a few more come in nearby, or get a travel charge if the customer needs them sooner.
Pair Big Jobs With Small Ones
A good wash day often has one big anchor job and a few small ones around it. The big job (a large house, a commercial pad, a long driveway with walks and patio) takes most of the day. The small jobs (a sidewalk, a set of steps, a small patio) fill the gaps and the end of the day.
Small jobs are flexible in a way big ones are not. If the anchor job runs long, a small job can slide to tomorrow with a quick text. If the anchor job finishes early, the crew can pick up a small job nearby. Keep a few small, flexible jobs near each anchor on the schedule.
Avoid stacking two anchors on one day unless you are sure of the timing. Two big house washes back to back leave no room for a weak spigot, a chatty customer or a wind delay, and the second customer is the one who pays for it.
Water, Chemical and Dump Stops Are Part of the Route
A wash truck's route includes more than customer addresses. If you run a buffer tank and the customer's spigot is slow, you may need to refill during the day. If you mix soft wash solution in bulk, the chemical has to last the whole day or you are driving back to the shop. If you do commercial work with wastewater recovery, the collected water has to be disposed of properly, which may mean a specific location.
Plan those stops in. A crew that runs out of chemical at noon and drives 30 minutes back to the shop has lost an hour. Load for the whole day, and note on each property anything that affects supply: no outdoor spigot, a well with low flow, or a requirement that runoff not go into the storm drain.
Start and end matter too. The first job of the day should be close to the shop or along the way out, and the last one should leave the crew heading home. That sounds obvious, but schedules built in the order customers called rarely do it.
Put the Day in Order
Once you have chosen the jobs for a day, the order is the easy part. Auto-routing orders a day's stops by distance, which handles most wash days well. Then adjust for the things a distance calculation does not know.
Customer time windows come first. A business that needs its storefront done before opening goes first, whatever the map says. A homeowner who needs to be home to open the backyard gate might need a specific window.
Sun and heat come next for house washes. Many crews prefer to do house washes earlier in the day and save flatwork for the afternoon, when hot walls would make soft washing harder but concrete still cleans fine.
Then think about the next day. If tomorrow's first job is on the north side, ending today on the north side saves time in the morning. The route optimization features page shows how auto-routing orders the stops so you can make these adjustments on top.
Watching the Day as It Happens
Wash days drift. A job turns out bigger than measured, a customer adds a patio on site, the wind picks up and a house wash has to wait. The office can only help if it knows.
GPS location of the crew phone during the day shows where each truck actually is, which answers the customer who calls asking when you will arrive without having to call the crew in the middle of a job. The crew app marks each job done as it is finished, so the office can see how far along the day is.
If a job needs to move, the crew can skip it with a reason ("too windy for house wash," "customer not home, gate locked") and the office knows why. A skipped job should not vanish; it should go back to the Waiting List so it gets rescheduled instead of forgotten. Make a habit of reviewing skipped jobs at the end of every day.
Tie Routing to Your Lawn Neighborhoods
If you run lawn routes, you already have the best map for wash routing: the neighborhoods where your mowing customers live. Wash work sold to those customers is clustered from day one, because your lawn routes are clustered.
Use that. When you plan a wash day, check which mowing neighborhoods have approved wash jobs and build the day there. When you market washing, start with the neighborhoods where you already have the most lawn stops, so the work that comes back is easy to route.
Over time you can even match wash days to mowing days, sending the wash crew to the same neighborhood the mowing crew covers that day. If something goes wrong, help is nearby, and the neighbors see two of your trucks on one street, which is good advertising. Our scheduling post covers how to keep both kinds of work on one calendar without double-booking people.
