Pressure washing equipment list: 22 things to buy now, rent or add later

This is the gear list we would hand a new pressure washing owner: what each piece does, which specs matter, and whether to buy it now, rent it, or wait. Items 1 to 14 cover the first paid job. Items 15 to 19 are upgrades for once you know which work you are booking. Items 20 to 22 are the non-tool pieces that decide whether the phone rings and invoices get paid. We list no prices, since they swing by region, season and dealer; get current quotes locally. If the company is still on paper, read how to start a pressure washing business first, and visit our pressure washing industry page to see how we build websites, phone lines and a CRM around washing work.

1. A gas pressure washer sized to your water supply

The machine is the heart of the rig. Pressure (PSI) breaks grime loose; flow (gallons per minute, GPM) carries it away, so a higher-flow unit rinses siding and finishes concrete faster. Your water source caps flow, which is why you size the pump to the spigot or tank you will really be pulling from.

Look for: a pump the manufacturer rates for commercial duty, rebuild kits you can buy separately, an adjustable unloader, a thermal relief valve, and an engine your local dealer services. Ask the dealer to explain belt drive versus direct drive on the models they stock. Buy or rent: buy, new or dealer-inspected used. Safety: an OSHA fact sheet on carbon monoxide advises against using gas-powered engines, power washers among them, in enclosed spaces. Keep the engine outside garages and wash bays.

2. A spigot test and, if needed, a buffer tank

Before you shop for a machine, time how long a five-gallon bucket takes to fill at a few customers' spigots and convert that to gallons per minute (divide 300 by the seconds it took, so a 60-second fill is 5 GPM and a 75-second fill is 4 GPM). If the spigot is slower than the pump you want, a buffer tank with a float valve fills between pulls and keeps the pump fed. The pump's manual lists the inlet supply it needs.

Look for: a tank with bulkhead fittings, a float valve, a strainer, and straps or a frame that bolts down. Watch the weight: the USGS lists water at about 62.4 pounds per cubic foot, which works out to about 8.3 pounds per gallon, since a cubic foot holds about 7.48 gallons. A 200-gallon tank holds about 1,670 pounds of water before you add the machine and reels. Buy: on day one if your spigot test comes up short.

3. High-pressure hose, a reel and a good supply hose

You will drag hose around every house you wash, so its quality shows up in your hours and your temper. The high-pressure line runs from pump to gun; the supply hose feeds the pump from the spigot or tank.

Look for: a high-pressure hose rated at or above your machine's maximum PSI, a non-marking cover for light concrete, enough length to reach the back of a typical house from the driveway, and a reel with a swivel rated for that pressure. For supply, use a hose wide enough to deliver the flow your pump needs. Buy: day one. Safety: check the hose for bulges, cuts and worn cover before each job, and retire a damaged section instead of taping it. A burst line under pressure whips hard.

4. Spray gun, wand, quick connects and nozzle tips

The gun and wand are what you hold all day, and the tips decide whether you clean a surface or carve it. Tips are sized by orifice to match a machine's flow and pressure, and come in different spray angles.

Look for: a gun with a trigger lock, a wand length that suits your height, stainless or plated quick connects, a ball valve at the wand, and a full set of tips in the orifice size your pump chart calls for, plus spares. Buy: day one. Safety: set the trigger lock every time you put the gun down, keep hands and feet out of the spray, and never point the wand at a person or pet. Start every new surface with the widest tip and work closer, testing in a hidden spot first.

5. A surface cleaner for flatwork

A surface cleaner is a spinning bar with nozzles under a round housing. It cleans driveways, sidewalks and patios evenly, without the stripes a wand leaves, and much faster. If concrete is on your service menu, this is how you hit a quote on time.

Look for: a size the maker rates for your machine's flow and pressure (bigger is not better if your pump cannot feed it), a swivel you can rebuild, height adjustment, and casters or handles that suit your back. Buy matching tips for the spray bar. Buy or rent: buy if you sell concrete cleaning; rent one for a single big commercial lot. Safety: release the trigger before you tip the housing up, and wear eye protection, because grit can fly out from under the skirt.

6. A downstream injector, then a soft wash pump

Most house washing is soft washing: a cleaning solution applied at low pressure, then rinsed. A downstream injector pulls chemical into the low-pressure stream after the pump, which is the simplest way to start. A dedicated 12-volt soft wash pump with its own tank lets you mix stronger solutions and reach roofs and second stories.

Look for: on a dedicated pump, materials listed as compatible with the chemicals you plan to run (ask the pump maker for its chemical compatibility chart before you buy), a lidded tank, a separate chemical hose and a reliable battery and charger. Buy: the injector on day one; the soft wash pump once house washes fill your week. Safety: label every tank and line with what is in it.

7. Cleaning chemicals, measuring tools and labeled jugs

Expect to carry a house wash solution, a surfactant, a degreaser for concrete and possibly rust or wood products. Measure every mix with a marked pitcher and a funnel so results stay the same job to job.

Look for: products whose labels name the surfaces you clean, sealed jugs that stay upright in transit, and a printed safety data sheet for each one. OSHA's guide to safety data sheets explains the 16 sections: Section 7 covers handling and storage, Section 8 lists protective equipment down to the glove material, and Section 10 lists the classes of materials the chemical could react with dangerously. Buy: day one, in quantities you can store safely. Employees: the moment a helper handles these jugs, the federal hazard communication rules require labels, accessible data sheets and training for the hazardous chemicals your workers use.

8. Eye, hand, hearing and foot protection

Pressure washing puts water, grit and cleaning solution at face height, beside an engine running for hours. Protective gear is a day-one purchase.

Look for: Z87.1-rated safety glasses or goggles (the OSHA eye and face protection rule lists that standard); chemical-resistant gloves in the material your data sheets name; waterproof boots with real tread; rain gear; and earplugs or muffs. With employees: the OSHA PPE standard requires a written hazard assessment and says employers provide required gear at no cost to employees, with limited exceptions. Under the noise standard, exposure at an 8-hour average of 85 decibels or more triggers a hearing conservation program and free hearing protectors.

9. Plant covers, tape and a pump sprayer

A house wash can damage what sits around the siding: shrubs scorched by solution, water forced into a light fixture or outlet, overspray drifting onto a parked car. A small kit and ten minutes of setup prevent most of it.

Look for: lightweight tarps or plant covers, plastic sheeting and painter's tape for outlets, fixtures and door hardware, and a garden sprayer or second hose to soak plants before you apply solution and rinse them after. Bring a note card listing what you covered so you uncover all of it. Buy: day one. Know what to skip: window makers warn against blasting their products; one major manufacturer's care guide tells homeowners to avoid power washing window frames. Keep pressure off glass, seals and frames.

10. An extension wand and a ladder

Second-story eaves, gutter faces and high corners need reach. Soft washing from the ground with an extension wand or the soft wash pump's throw is safer than climbing with a pressurized gun, so reach for the ladder only when you must.

Look for: a telescoping wand rated for your pressure, and a ladder sized to the homes you wash with a duty rating that covers you plus gear. Pick fiberglass side rails if you may work near service drops. OSHA's electrical work rule calls for nonconductive siderails where a ladder could contact exposed energized parts. Buy: day one. Safety: the ladder standard requires inspection before each shift, no moving a ladder while someone is on it, and no carrying loads that could throw you off balance.

11. A truck, a trailer or a truck-bed setup

Many owners start with the machine and reels bolted into a pickup bed, then move to a trailer once a tank and second reel join the rig. Either way, everything must be strapped or bolted down; a loose tank shifts under braking.

Look for: payload and towing ratings above the full weight of your rig with water, a trailer with a gross weight rating to match, and lockable storage. Know the federal line: 49 CFR 390.5 treats a truck, or a truck and trailer together, as a commercial motor vehicle when its weight rating or actual weight, whichever is greater, reaches 10,001 pounds and it carries property in interstate commerce. If your rig could qualify, read the FMCSA rules, and check in-state rules with your state's transportation agency before you buy. Our guides to buying a work truck and commercial auto insurance cover the rest.

12. Drain covers and berms

Wash water picks up whatever was on the surface. The EPA's stormwater program page warns that runoff picks up trash, chemicals, oils and sediment that can harm rivers, streams, lakes and coastal waters. Local rules on what wash water may go down a street drain differ, so the answer can change from town to town.

Look for: weighted drain covers or mats in the sizes your local drains use, and a few portable berms to steer water toward landscaping or a collection point. Buy: covers on day one; full recovery gear later (item 17). Before your first commercial job: phone the city's public works or stormwater department and ask what it requires from mobile washers.

13. A field repair kit and fuel

With spares on the rig, a blown O-ring or a lost tip becomes a quick swap in the driveway instead of a trip to the dealer. Keep a small box that matches the fittings you actually run.

Look for: spare O-rings in each size, extra quick connects and plugs, a second set of nozzle tips, thread seal tape, pump oil, an engine air filter and spark plug, a hose repair coupler, and the wrenches and picks to swap them. Carry fuel in containers made for gasoline, strapped upright and away from the engine's hot exhaust. Buy: day one, then restock it every Friday. Safety: shut off and cool the engine before refueling, relieve pressure before you disconnect anything, and follow the maintenance schedule in your pump and engine manuals.

14. Measuring tools for fast quotes

Pressure washing is priced by the surface and its size, so the tools that measure are sales tools. A measuring wheel or laser measure handles driveways and decks on site; satellite measurement handles many houses before you ever drive out.

Look for: a measuring wheel that folds into the truck, a laser measure for decks and walls, and a phone setup that saves every measurement and photo with the customer's address, so a repeat quote next spring is nearly instant. Buy: day one. Why it pays: a homeowner who gets a clear price the same afternoon has less reason to keep shopping. Our pressure washing pricing guide turns those measurements into prices.

15. A hot water pressure washer (upgrade)

Cold water handles most houses and concrete. Grease, oil, chewing gum, drive-thrus, dumpster pads and fleet washing go faster with heat, which is why commercial-heavy companies add a hot water unit with a fuel-fired burner.

Look for: a burner your dealer can service, the fuel type you can buy easily, and a frame that fits your trailer's weight rating. Buy or rent: rent or demo one before you buy, and buy only when booked commercial work keeps it busy. Safety: a burner adds a second source of exhaust and hot surfaces. That same OSHA fact sheet lists heaters next to power washers, so the open-air rule from item 1 applies twice over.

16. A roof cleaning setup (upgrade)

Roof cleaning is a specialty: bigger jobs, more risk, and more ways to damage property. It uses low-pressure application from a soft wash pump with enough reach, careful mixing, and heavy rinsing of plants and gutters.

Look for: a pump and hose that throw solution to the roof's peak from the ground or the edge, plus fall protection that fits the roofs in your area. Before you buy: read the roofing manufacturer's cleaning guidance for the shingles or tiles you will treat, take hands-on training, and ask your insurance agent to confirm in writing that the policy covers roof work. Buy: later, once house washing is steady and the training is done.

17. Water recovery equipment (upgrade)

Some commercial properties and cities expect you to capture wash water instead of letting it run off. A recovery setup uses drain covers or berms to pool the water and a vacuum or sump pump to move it into a holding tank, where it can be filtered and disposed of where local rules allow.

Look for: a vacuum or pump sized to your machine's flow, a holding tank your trailer can carry when full, and written guidance from the local sewer authority on disposal. Buy or rent: rent for a single contract; buy when recurring commercial accounts require capture. Bid it in: recovery adds setup, pumping and disposal time, so list it as its own line on the quote.

18. A skid unit or enclosed trailer (upgrade)

A skid combines pump, engine, tank and reels on one frame, so setup on each job takes minutes. An enclosed trailer protects the rig from weather and theft and gives you a dry place for chemicals and the repair kit.

Look for: a frame that bolts down at the points the trailer maker specifies, reels you can reach without climbing, ventilation, and a layout that keeps chemicals away from fuel. Recheck total weight with a full tank against every rating on the truck and trailer. Buy: once you run enough jobs a day that setup time is costing you work. Safety: never run an engine inside a closed trailer.

19. Wood restoration gear (upgrade)

Decks and fences open a second service line: cleaning, brightening and often sealing or staining. That work needs a few tools a house washer does not carry.

Look for: wood-specific cleaners and brighteners whose labels match the wood you will treat, a dedicated pump sprayer for each, stiff brushes, a wood moisture meter so you know when the boards are dry enough for stain, and the sealer or stain maker's application instructions. Buy: when deck and fence requests start showing up in your inbox. Safety: wood strippers can be harsh. Read Section 8 of each data sheet for gloves and eye protection, and keep them off plants and pets.

20. A business phone number that texts back missed calls

You cannot answer with a wand in your hands and an engine running beside you. A separate business line keeps your cell number private, rings whoever is free, and sends an automatic text to anyone you miss so the homeowner does not move on to the next washer in the search results. The options are compared in our business phone number guide, and the phone systems service page describes what we install for washing crews.

21. Quoting, scheduling and invoicing software

In most climates, pressure washing requests bunch up in spring, and paper quotes get lost in the rush. Pick software that turns a quote request with photos into a priced quote, books the approved job, sends the invoice with a card payment link, and reminds last year's customers when their anniversary comes around. Our pressure washing software roundup compares off-the-shelf tools, and the custom CRM page covers when owning your own system makes sense.

22. Insurance that fits chemicals and overspray

General liability answers for harm your work does to someone else's property, and a washer's risks are specific: a failed window seal, a scorched shrub bed, overspray on a neighbor's car. Policies differ in what they exclude, so ask your agent directly about pollution or chemical exclusions, damage to the surfaces you are cleaning, coverage for tools and equipment on the trailer, and commercial auto for the truck that tows it. Property managers and commercial clients often want your insurance certificate on file before the first wash. For policy-by-policy detail, read the insurance guide for contractors and our plain-English take on general liability.

Where to start

Three steps come first. Run the spigot test (item 2) on a few friends' houses before you shop, because it tells you which machine and tank to buy. Then buy the pressure washer, hose and tips that match it (items 1, 3 and 4). Then put the protective gear and safety data sheets on the truck (items 7 and 8) before the first paid job. Everything from item 15 on can wait until the schedule asks for it. When the equipment is sorted, our start a company hub covers what comes next, and a free launch plan from us maps out the phone, website and quote flow you will need for the first spring rush.
