Software for the yard running pressure washers.

A pressure washer is the unit a rental yard hands out by the dozen — small, in constant demand, and easy to wreck in a single afternoon. It knocks mud off iron at the yard, strips grease from a shop floor, and cuts baked-on grime that a garden hose just smears around. That high-volume, low-supervision life is exactly what makes washers hard to run as a fleet: the unit leaves with a hose, a gun, a wand, and a fistful of tips that all need to come back, the pump dies the instant a customer runs it dry, and the same cold-water class gets double-booked across overlapping jobs. EquipFlow runs pressure washers the way the yard that built it runs them — dispatch, billing, maintenance, and return inspection on one record per unit.

Built inside Rental King, right now.

Rental King is a heavy-equipment rental yard in Odessa and Midland, TX. They run pressure washers, manlifts, forklifts, light towers, generators, compressors, and water trucks on MSA contracts through the Permian Basin — 24/7, oilfield pace. EquipFlow was designed and first deployed inside that yard. Every feature was tested against their live operation before it shipped. The product runs there today.

Pressure washers are the rental that looks cheap and bleeds money quietly. A unit returned with a seized pump is a major repair on a small asset, and it goes unnoticed if the return is waved through the gate caked in grime. The hose, gun, and tips wander off one piece at a time, and each missing piece is either a charge that never gets made or a unit that cannot go back out. The hour meter still feeds both maintenance and billing, so it has to be captured the same way every time — at return, on the inspection, against the rental record. When dispatch, billing, maintenance, and inspection all read from one unit record, the dispatcher sends the complete kit, the mechanic services on real hours, and the bookkeeper charges the dry-run pump damage with a photo behind it. That discipline is what keeps a high-churn washer fleet from running at a loss.

How EquipFlow handles pressure washers on the dispatch board.

A pressure washer is a small, easily mishandled rental that moves a lot, so the dispatch board treats each unit as a line a dispatcher can see at a glance — at the yard, out on a job, or due back — on the same responsive screen at any hour. The trap with pressure washers is what rides along: the unit means nothing without the high-pressure hose, the trigger gun and wand, and the right nozzle tips, and a hot-water unit needs its burner fuel topped off. A washer dispatched short a wand or a quick-coupler is a return trip, so the dispatcher confirms the hose, gun, and tip set on the rental record before the truck leaves. Because the same cold-water class is double-booked easily across overlapping jobs, the board surfaces the conflict when the unit is assigned, not when a customer calls asking where their washer is.

Billing pressure washers — MSA, standby, and site-level tax.

When a pressure washer goes to an oilfield account on an MSA, the rate override lives on the customer record per equipment class, so a washer rental for that account applies the negotiated rate automatically rather than the dispatcher pulling it from a sheet. Washers rent short and often, so day-and-week structures and the MSA rate both flow from the same record. When a unit sits staged on a pad through a job delay — common when the wash crew is waiting on access or a permit — standby is billed at a rate separate from active use, marked by the dispatcher so the invoice carries both lines without a month-end rebuild. Burner fuel, lost-tip charges, and delivery and pickup ride the same invoice. Tax is set on the delivery-site record, so a unit that crossed a county line still gets the right rate. Invoices post to QuickBooks Online on close.

Maintenance on pressure washers.

Pressure washer PM is hour-meter driven, not calendar driven, because a unit on a turnaround can run all day every day while a yard spare sits for a season. The hour reading posts when the return inspection records it, and the maintenance module advances the PM clock from that reading so service lands against real use. The pump is the heart of the unit, so PM leans on pump oil, the unloader valve, and inlet-screen condition alongside the engine oil, air filter, and spark or glow components. Hot-water units add the burner: fuel filter, nozzle, and a coil that scales up over time on hard water. Work orders, parts, and meter history live on the unit record, which is also where a damage charge from a return inspection becomes a repair ticket — a seized pump from a dry run, a kinked hose, a torn trigger gun.

Pressure Washer return inspections.

Two inspection rhythms apply. The operator-facing check before each use — water supply hooked up and flowing, oil levels, no leaks, the unloader cycling — is the customer's responsibility while the washer is on rent, and it is the single check that keeps a pump alive. The yard's own control is the return inspection: before a washer comes off rent, the driver runs a mobile-web checklist on a phone with no app to install, captures the hour reading, and attaches required photos that cannot be skipped. Washer-specific checks matter here — pump for cavitation scoring and oil that turned milky from a dry run, the high-pressure hose for abrasion and burst-jacket spots, the gun and wand, the nozzle tips that walk off, and on hot-water units the coil and burner. The inspection ties to the rental record before the truck leaves, so a seized-pump dispute has a photo and a timestamp behind it.

What you give up running pressure washers in EquipFlow.

EquipFlow is a web app, so the return inspection needs a signal to load. On a remote lease with no coverage, the driver cannot complete the mobile inspection on site; most yards run it at the yard on return instead, which means the photos and hour reading land a little later than ideal. There is no built-in telematics today, so run-hours from a unit are captured at return inspection rather than pulled automatically — which is the norm for small gear like this anyway. And the rate logic is built around the MSA-and-standby model the oilfield runs on; a yard with an unusual washer-billing structure should bring it to the demo so it can be scoped honestly.
