Nothing beats that “fresh-from-the-showroom” sparkle, but achieving it without endless scrubbing or paying for weekly pro details means you need the right muscle in your garage. An electric pressure washer built for car detailing is that quiet, emissions-free powerhouse that lifts road film, brake dust, and winter salt in minutes—without the swirl marks or paint damage old-school hoses often leave behind. Whether you’re a weekend hobbyist protecting a ceramic coating or a mobile detailer scaling into five-figure monthly revenue, the washer you choose becomes the heartbeat of your entire workflow.

Below, we’ll unpack everything that separates a gimmicky patio sprayer from a precision detailing tool, from PSI sweet spots to quick-connect chem injectors. By the end, you’ll know exactly how to shop once, cry once, and invest in a machine that turns Sunday washes into satisfying therapy sessions—and maybe even a side hustle.

Check Price

Overview: The Westinghouse ePX3100v is a compact electric pressure washer that delivers professional-grade cleaning power in a package light enough to carry with one finger. At just 18 pounds, this 2100 PSI machine targets homeowners who want gas-like performance without the noise, fumes, or maintenance.

What Makes It Stand Out: Its 17.5-inch pro-style steel wand and turbo nozzle punch well above its weight class, stripping mildew from vinyl siding and chewing through driveway grime typically reserved for bulkier gas units. The detachable foam cannon turns weekend car washes into satisfying snow-foam experiences, while the auto-stop pump extends motor life and keeps energy use low.

Value for Money: $129 lands you a three-year warranty, steel components where rivals use plastic, and a true 1800 PSI working pressure that beats most sub-$150 competitors that inflate numbers. Factor in zero gas, oil, or seasonal carburetor service and the lifetime cost drops even lower.

Strengths and Weaknesses: Pros: feather-weight portability; steel wand won’t snap like aluminum; 20-foot hose doesn’t kink; quick-nozzle changes; surprisingly quiet.
Cons: 1.2 GPM flow is slower than gas models on large decks; 20-foot hose and 35-foot cord may still force one outlet relocation; plastic hose adapter can cross-thread if rushed.

Bottom Line: For urban townhouses, apartments, or anyone who stores tools indoors, the ePX3100v is the sweet-spot between toy washers and heavy gas beasts. Buy it, hang it on a garage hook, and retire the scrub brush forever.


2. Westinghouse ePX3100 Electric Pressure Washer, 2300 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios

Westinghouse ePX3100 Electric Pressure Washer, 2300 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios
Check Price

Overview:
The Westinghouse ePX3100 is a pint-sized powerhouse aimed at homeowners who want pro-style performance without the bulk or noise of gas units. Delivering 2300 max PSI and 1.76 max GPM from a universal motor, it strips grime off siding, restores gray decking, and blasts wheel wells while staying small enough to store on a pantry shelf.

What Makes It Stand Out:
Anti-tipping tech is the star—four locking caster wheels and a ground-hugging center of gravity let you yank the hose without the washer somersaulting. The 17.5-inch steel wand feels contractor-grade, and the onboard 20-ounce soap tank means no dangling pickle jars of detergent. Add 360° steering and a featherweight 19-lb frame, and you have a unit that follows you like a puppy instead of fighting like a stubborn vacuum.

Value for Money:
At $139 it undercuts most 2000-plus PSI competitors by $30-$60, yet bundles a metal wand, five quick-connect tips, and a three-year warranty. You’d pay extra for each of those on other budget models, so the price feels honest, not cheap.

Strengths and Weaknesses:

  • Pro-style steel wand and five nozzles included
  • Tiny footprint; stores upright in a closet
  • Auto-stop saves pump life and ear drums
  • 25-ft hose is nylon, not rubber; can kink if coiled hot
  • 120-volt cord could be longer; plan on an exterior-rated extension

Bottom Line:
For suburban homes, apartments, or anyone who cleans less than a city block a year, the ePX3100 punches above its weight. It’s stable, stowable, and strong enough to make Saturday chores feel like Tuesday victories.


3. Westinghouse ePX3500 Electric Pressure Washer, 2500 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios

Westinghouse ePX3500 Electric Pressure Washer, 2500 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios
Check Price

Overview: The Westinghouse ePX3500 is a compact electric pressure washer that delivers professional-grade cleaning power in a remarkably portable package. With 2500 max PSI and 1.76 GPM flow rate, this lightweight unit weighs just 19 pounds while offering the performance typically found in much larger, gas-powered machines. The four-wheel design and anti-tipping technology make it exceptionally maneuverable around your property.

What Makes It Stand Out: This pressure washer’s standout feature is its innovative 360° steering system with four quick-lock wheels, eliminating the common frustration of tipping over while pulling the hose. The ultra-compact 16.5” height allows for easy storage in tight spaces like apartment closets or garage shelves. The pro-style steel wand with five quick-connect nozzles provides versatility for everything from delicate car washing to tough concrete cleaning.

Value for Money: At $169, the ePX3500 offers exceptional value compared to similar electric pressure washers. The inclusion of a 3-year warranty, professional-grade steel wand, and anti-tipping technology would typically cost $50-100 more from competitors. The onboard soap tank adds convenience without extra accessories needed.

Strengths and Weaknesses: Strengths include the anti-tipping design, compact storage size, quiet operation, and comprehensive nozzle set. The automatic pump shutoff extends motor life. Weaknesses include the 25-foot hose being shorter than ideal for larger properties, and the 2000 PSI rated (vs 2500 max) performance may struggle with the most stubborn stains.

Bottom Line: The Westinghouse ePX3500 is an excellent choice for homeowners seeking powerful cleaning without the bulk of traditional pressure washers. Its innovative design and reliable performance make it ideal for regular maintenance cleaning of vehicles, decks, and home exteriors.

Chemical Guys Electric Pressure Washer PM2000 PRO – 2030 PSI, 1.77 GPM, 25’ Flex Hose, Compact Design, 360° Casters, Standard Connections, Cable Storage – EQP411
Check Price

Overview:
The Chemical Guys PM2000 PRO is a garage-friendly electric pressure washer that squeezes 2,030 PSI and 1.77 GPM out of a 14.5-AMP motor while staying quieter and smaller than most gas rigs. A 25-ft kink-resistant hose, 35-ft GFCI cord, and four 360° casters let you circle a car or deck without ever lifting the unit.

What Makes It Stand Out:
Mobility is the headline—roll it like a suitcase, wrap the hose and cord on the integrated hooks, and stash the wand in the molded dock. Everything stores onboard, so you’re ready the moment the driveway warms up. Standard ¼-in. QC fittings mean your existing foam cannon or snub-nose gun bolts right on, no adapters needed.

Value for Money:
At $224.99, it lands below most “pro-sumer” electrics yet ships with real brass connections, a stainless wand, and a detergent bottle. You’re paying for convenience and brand trust rather than raw specs, but the price still undercuts comparable Ryobi/Sun Joe bundles once you add their caddies and longer hoses.

Strengths and Weaknesses:
Pros: whisper-quiet operation, true rolling cart, universal fittings, compact vertical storage, reputable customer service.
Cons: plastic hose reel feels flimsy, no pressure gauge, trigger lock could be sturdier, and 1.77 GPM is shy of the 2.0-plus needed for pro-level surface cleaners.

Bottom Line:
For driveway detailers and weekend patio washers who want gas-style mobility without the noise, oil, or maintenance, the PM2000 PRO is the easiest $225 you’ll spend. Power users who need faster surface-cleaning should look at 2.3–2.5 GPM models, but everyone else can buy with confidence.

Electric Pressure Washer, 2.5 GPM Power Washer with 4 Quick Connect Nozzles & Foam Cannon, Portable High Pressure Washer Cleaning Machine for Cars Fences Driveways Patios
Check Price

Overview:
This $69.33 electric pressure washer delivers 2.5 GPM of flow—rare at this price—through a compact, roll-away chassis that arrives ready to work. Four brass quick-connect nozzles, a foam cannon, 20-ft hose, and 16-ft cord are all included; no trips to the hardware store required. It draws from either a faucet or a bucket, so you can wash the car in the street or the boat at the dock without plumbing drama.

What Makes It Stand Out:
Budget washers usually top out at 1.8 GPM and plastic fittings; this one keeps the 2.5 GPM rating and upgrades to brass connectors, steel-braided hose, and a locking wand—specs normally seen north of $120. The anti-tilt chassis and dual-wheel cart add stability on uneven driveways, while the integrated cord/hose hooks keep everything tidy between jobs.

Value for Money:
At under seventy bucks you’re getting flow rate, metal fittings, and a foam cannon that rivals $40 stand-alone units. Even if the motor lasts only a few seasons, the accessories alone justify the price for light-duty homeowners.

Strengths and Weaknesses:
Pros:

  • True 2.5 GPM flow speeds up rinsing
  • Brass nozzles & steel hose resist leaks
  • Bucket feed option for remote cleaning
  • Safety lock & cord management built-in

Cons:

  • Pressure (rated 1800-2000 PSI) is modest; won’t strip old paint
  • Universal motor is louder and warmer than induction units
  • Short, one-year warranty signals entry-level longevity

Bottom Line:
For routine car washes, patio sweeps, and fence refreshes, this washer punches well above its price tag. Power-hungry pros should look elsewhere, but casual users seeking maximum flow and minimum spend will be hard-pressed to find a better starter kit.


6. CRAFTSMAN Electric Pressure Washer, Cold Water, 1700-PSI, 1.2-GPM, Corded (CMEPW1700)

CRAFTSMAN Electric Pressure Washer, Cold Water, 1700-PSI, 1.2-GPM, Corded (CMEPW1700)
Check Price

Overview:
The CRAFTSMAN CMEPW1700 is a compact, electric cold-water pressure washer aimed at homeowners who want pro-style cleaning without the hassle of gas engines. Delivering 1,700 PSI at 1.2 GPM, it’s strong enough for decks, patio furniture, siding, and vehicles yet light enough to carry one-handed at 19 lb.

What Makes It Stand Out:
CRAFTSMAN bundles thoughtful “garage-friendly” details rarely seen at this price: a built-in soap bottle that clicks on the wand, a kink-resistant 20-ft hose that stores flat on the reel, and a 35-ft cord that actually reaches the far end of most driveways without an extension. Every accessory—three quick-connect nozzles, wand, and hose—snaps onto the unit, so nothing disappears between jobs.

Value for Money:
At $119 the CMEPW1700 sits in the sweet-spot between throw-away discount models and $200+ units. You’re paying for name-brand reliability, a two-year warranty, and design touches (hose reel, cord wrap, soap tank) that cost extra on competitors.

Strengths and Weaknesses:
Pros: quiet induction motor, tool-free assembly, leak-free brass connections, tidy on-board storage, and CRAFTSMAN’s nationwide service network.
Cons: 1.2 GPM flow is slower than 1.4–1.5 GPM washers, so large driveways take longer; wand is only 15 in., forcing occasional crouching; plastic hose reel feels flimsy when cranked hard.

Bottom Line:
For routine home cleanup the CMEPW1700 punches above its weight, combining usable pressure with unmatched organization and warranty support. Power-hungry users should look higher, but everyone else can buy confidently—this is the easiest $119 you’ll spend on outdoor maintenance.

Washer with 4 Quick Connect Nozzles, Cleaning Machine with Foam Cannon
Check Price

Overview:
This compact electric pressure washer delivers a respectable 2,000 PSI punch while staying under 20 lbs, making weekend car-wash or deck-revival sessions far less intimidating. The kit ships with four quick-connect tips (0°, 15°, 25°, 40°) plus a bonus foam cannon, so you can move from blasting moss off pavers to gently sudsing a sedan without tools or downtime.

What Makes It Stand Out:
The integrated 0.4-gallon foam tank is the star—most budget washers force you to buy a separate lance. Twist the dial and thick snow-foam blankets the surface, loosening grit before you ever touch it with a mitt. A 35-ft power cord and 20-ft hose give real reach without an extension lead, and the motor auto-stops when you release the trigger, saving wear and electricity.

Value for Money:
At $84.98 it’s cheaper than three professional detailing visits. Replacement wands and O-rings are standard aftermarket parts, so running costs stay low. You’re essentially getting washer + foam cannon + nozzle set for the price competitors charge for the machine alone.

Strengths and Weaknesses:
Pros: lightweight, tool-free nozzle swaps, generous hose length, quiet 75-dB operation, excellent foam coverage.
Cons: plastic hose reel feels flimsy, 1.4 GPM flow is slow for large driveways, hose tends to kink if not unrolled fully, unit tips over if you yank it hard.

Bottom Line:
For apartments, small patios, and car owners who want snow-foam luxury on a shoestring, this washer over-delivers. Heavy-duty contractors or huge decks should look upstream, but everyone else can click “buy” with confidence.

Check Price

Overview:
The PATOOLIO 109-dollar electric pressure washer bundles a full-size 23-ft hose, four quick-swap brass nozzles, and a foam cannon into a rolling, bucket-fed package that targets budget-conscious homeowners who want one machine for cars, decks, driveways and patio furniture.

What Makes It Stand Out:
Unlike most entry-level washers, it ships with a legit brass-head foam cannon—normally a $25 add-on—plus stainless-steel spray wand, metal quick-connects and steel-braid hose that rarely appear under $150. The TSS auto-stop pump, child-lock trigger and ability to siphon from a bucket make it surprisingly pro-featured for the price.

Value for Money:
At $109.97 you’re essentially paying for a basic 1800-2000 PSI unit and getting the foam cannon, upgraded hose, metal fittings and rolling chassis free. Comparable bundles from Sun Joe or Greenworks run $160-190, so the savings are real if the motor holds up.

Strengths and Weaknesses:
Pros: foam cannon included; metal connections resist leaks; 23-ft hose plus two wheels give excellent reach; TSS saves energy and pump life; bucket draw lets you wash where there’s no spigot.
Cons: pressure specs aren’t verified (no PSI/GBR numbers listed); motor housing is largely plastic; short 35-ft power cord often needs an extension; warranty terms vague; customer service responsiveness unproven.

Bottom Line:
For light-duty weekend cleaning—think cars, patio sets and mildewy fences—the PATOOLIO delivers accessories and build touches normally reserved for pricier rigs. Just don’t expect contractor-grade power or a bullet-proof motor; treat it gently and it earns its $110 keep.

Overview:
Delivering 2,300 PSI and 2.5 GPM from a compact, wheeled frame, this $94.97 electric unit turns weekend grime-blasting into a one-person show. Four snap-in tips plus a foam cannon cover everything from muddy trucks to mildewed siding, while a 20-ft hose and dual wheels let you circle the car or circle the house without dragging the machine.

What Makes It Stand Out:
You rarely see a true 2.5 GPM flow rate under the $100 mark; that extra gallon-per-minute translates to faster rinsing and less streaking. The integrated foam cannon is not a cheap after-market bottle—it threads on securely and actually aerates soap for thick cling. Finally, every accessory has a molded parking spot, so you’re not hunting for nozzles in the grass.

Value for Money:
Comparable washers with similar PSI/GPM specs sit closer to $150–$180 and still charge extra for a foam cannon. Here you get cart-style mobility, onboard storage, and five cleaning attachments for basically the cost of a decent cordless drill.

Strengths and Weaknesses:
Pros: strong real-world pressure; foam cannon included; tool-free assembly; organized storage; Total Stop System saves pump life.
Cons: 35-ft power cord is shorter than some rivals; plastic hose adapter feels fragile; unit tips if hose is yanked hard despite “anti-tip” claim; a bit loud at 85 dB.

Bottom Line:
For budget-conscious homeowners who want car-show foam and patio-brightening power without renting gear, this washer punches well above its price. Treat the fittings gently and it’s the best sub-$100 cleaning force you can buy today.


10. Westinghouse ePX3050 Electric Pressure Washer, 2100 Max PSI 1.76 Max GPM with Foam Cannon, for Cars/Fences/Driveways/Home/Patios

Westinghouse ePX3050 Electric Pressure Washer, 2100 Max PSI 1.76 Max GPM with Foam Cannon, for Cars/Fences/Driveways/Home/Patios
Check Price

Overview:
The Westinghouse ePX3050 is a compact, 120 V electric pressure washer rated at 1,800 PSI / 1.2 GPM (2100 PSI / 1.76 GPM “max” under laboratory conditions). It ships with a 20 ft kink-resistant hose, two quick-connect nozzles, a lightweight spray gun, and a bonus foam cannon—everything you need to clean cars, patio sets, fences, and driveway grime straight out of the box.

What Makes It Stand Out:
At only 26 in tall and 16 lb, the unit stores on a shelf and rolls on 5-inch never-flat wheels, a rarity in the sub-$100 class. The axial pump’s auto-stop extends motor life and slashes noise, while the 35 ft GFCI cord covers most suburban facades without an extension lead. Add the included foam cannon and lifetime tech support, and the ePX3050 feels like a premium package disguised in a budget shell.

Value for Money:
$99.99 lands you a washer, foam cannon, two nozzles, and a two-year warranty—items that cost $40–$60 separately from competitors. For light-duty homeowners, it’s cheaper than a weekend rental and pays for itself after two driveway cleanings.

Strengths and Weaknesses:
Pros: tiny footprint; quick assembly; quiet (≈78 dB); auto-stop saves water; foam cannon included; free lifetime tech line.
Cons: plastic hose adapter can leak if overtightened; 20 ft hose is short for second-story work; “max” PSI is optimistic—expect 1,500–1,700 PSI at the gun with typical faucet flow.

Bottom Line:
If your chores stay on the ground—cars, grills, patio stones—and you want maximum convenience for minimum cash, the Westinghouse ePX3050 is the best hundred bucks you’ll spend this spring.


Why Electric Beats Gas for Car Detailing

Electric motors run cooler, quieter, and emit zero carbon monoxide—huge when you’re working inside a garage or mobile trailer. They also weigh less, need zero oil changes, and start with the press of a trigger instead of a pull cord. For paint-safe, low-RPM fans that live at 1,200–2,000 PSI, electric units give you instant torque control and consistent flow without the pressure spikes that can strip wax or force water past weather-stripping.

Understanding PSI, GPM, and Cleaning Units

PSI (pounds per square inch) tells you how hard water hits; GPM (gallons per minute) tells you how much water is moving. Multiply the two and you get Cleaning Units (CU), the industry’s quick-glance power rating. For automotive finishes, aim for 1,200–1,900 PSI and 1.2–1.8 GPM, translating to roughly 1,500–3,400 CU—enough to blast grit but gentle enough to keep clear coat intact.

The Goldilocks Pressure Zone for Automotive Paint

Factory clear coats are only 25–50 microns thick—about half the width of a human hair. Exceed 2,000 PSI at the nozzle and you risk “burning” edges, peeling decals, or driving water into fragile electronics. Conversely, drop below 800 PSI and you’ll chase shampoo foam instead of removing it. Stay between 1,200–1,600 PSI at a 40° fan and you’ll dislodge salt, bugs, and tar without microscopic pitting.

Flow Rate (GPM) and Why It Matters More Than PSI

A higher GPM rinses faster, flushing loosened grit away before you wipe. Professional detailers often rank GPM above PSI because it cuts wash time in half, reduces towel contact (fewer swirls), and feeds foam cannons the volume they need to coat a full-size truck in 30 seconds. Anything under 1.2 GPM forces you to “chase” soap; above 2.0 GPM on 110 V circuits risks tripping breakers unless you step up to 220 V.

Motor Types: Universal vs. Induction vs. Brushless

Universal motors are light and cheap but scream at 90 dB and wear brushes every 50–100 hours. Induction motors run quieter, last 5× longer, and maintain torque under load—ideal for daily drivers. Brushless DC motors marry the compact size of universal with the longevity of induction, plus variable-speed circuitry that auto-dials pressure when you switch from roof to rocker panel. Budget permitting, go brushless for mobile rigs and induction for fixed bays.

Axial vs. Triplex Pumps: Durability Explained

Axial cam pumps spin in-line with the motor, cost less, and self-lubricate—great for 1–2 washes a week. Triplex plunger pumps offset 90° from the crankshaft, run cooler, and rebuild like mini-industrial units rated for 2,000+ hours. If you foresee weekend side gigs or fleet washing, triplex is the long-game play; rebuild kits cost under $80 and double service life.

Hose Length, Material, and Flexibility Considerations

Vinyl hoses kink below 50 °F and harden above 90 °F, turning your detail into yoga class. Look for 3/8 in. hybrid polymer or rubber-coated hoses rated −20 °F to 160 °F with bend restrictors at both ends. Twenty-five feet is workable for a sedan; 50 ft lets you circle a crew-cab dually without moving the unit. Pro tip: pair a 3/8 in. hose with 1/4 in. quick connects for 10% better flow than factory 1/4 in. lines.

Nozzle Angles & Quick-Connect Tips for Safe Washing

Color-coded tips control fan spread: 0° (red) is a laser—never use on paint; 15° (yellow) slices mud but can etch; 25° (green) is the sweet spot for wheel wells; 40° (white) blankets doors and hoods safely; 65° (black) is the low-pressure soap shooter. Always start 3 ft away, test on the bottom of the bumper, and keep the wand angled 45° to panel edges to avoid lifting clear coat.

Detergent Tanks vs. Foam Cannons: Which Setup Wins?

Built-in tanks dilute 20:1 through the pump, convenient for light dust but weak for thick snow foam. A 1-liter foam cannon hooked to a quick-connect lance pulls straight from a concentrate bottle, letting you tweak dilution knobs for 10″ clinging blankets that break down traffic film chemically—less scrubbing, less marring. Cannons also bypass the pump, prolonging seal life by keeping caustic shampoos out of the triplex chambers.

Portability: Weight, Wheels, and Compact Storage

A 35-lb unit with telescoping handle and 8″ never-flat tires climbs trailer ramps and stairs without two-person lifts. Look for on-board storage for spray wand, nozzles, and 35-ft cord to eliminate spaghetti piles. Cube-shaped designs under 18″ wide slide between wheel wells in SUVs, making mobile pop-ups realistic for condo dwellers.

Noise Levels: Keeping Neighbors (and Your Ears) Happy

Gas engines idle at 85–100 dB—conversation-killing, HOA-baiting territory. Electric models hover at 65–78 dB, roughly shower-volume. Brushless units drop another 5 dB thanks to slower fan speeds. If you wash at 6 a.m. before cars and coffee meets, aim under 75 dB; your neighbors (and ears) will thank you across hundreds of details.

Power Draw: 15 A Circuits, GFCI, and Extension-Cord Rules

Most 1,800 PSI/1.4 GPM machines pull 13 A steady—on a 15 A circuit you’ve got 2 A of headroom for LED lights or shop vac. Use a 12-gauge, 50-ft cord max to keep voltage drop under 3%; 14-gauge cords starve the motor, spike amps, and fry thermal fuses. Always plug into a GFCI outlet outdoors; pressure washers mix electricity and water every single pull of the trigger.

Cold Weather Care: Winterizing Electric Systems

Even electric pumps retain 4–6 oz of water in the head after shutdown. Blow it out with a 10-second trigger squeeze, then funnel 4 oz of RV anti-freeze through the soap tube until pink exits the nozzle. Store indoors above 32 °F; if you must leave it in a trailer, add a smart heater set to 40 °F—far cheaper than a cracked head or frozen seals come spring.

Warranty & Serviceability: What the Fine Print Really Means

“1-year bumper-to-bumper” sounds generous until you learn pumps are excluded. Read for separate pump (90 days), motor (2 years), and frame (lifetime) clauses. Brands that stock rebuild kits, publish parts diagrams, and maintain YouTube teardown channels save you weeks of downtime. Keep receipts; many warranties jump from 1 to 2 years simply by registering online within 30 days.

Budget vs. Premium: Where Extra Dollars Actually Go

Entry washers pair universal motors with axial pumps and ABS plastic reels—fine for 30 details a year. Step-up models swap in induction motors, brass heads, stainless pistons, and Cat or AR triplex pumps rated 500+ hours. At the top, you get digital torque control, Wi-Fi maintenance alerts, and aircraft-grade aluminum frames. ROI hits around detail #75 if you charge $80 per wash; after that, every gig is almost pure profit.

    Yes—stay under 1,200 PSI, use a 40° white tip, keep the wand 18 in. away, and avoid 90° angles to seams.

  2. How often should I change pump oil on an electric triplex pump?
    Every 100 hours or once a season; use non-detergent 30W or the manufacturer’s specified synthetic.

  3. Will a foam cannon work with any electric pressure washer?
    As long as your unit delivers 1.2+ GPM and you have a 1/4″ quick-connect coupler, most adjustable cannons will aerate properly.

  4. Why does my washer lose pressure after five minutes?
    Thermal valve may be dumping heated water; check inlet filter clogs, hose kinks, or an under-sized extension cord causing voltage drop.

  5. Is it okay to run bleach through the detergent tank for mold removal?
    Never—sodium hypochlorite attacks pump seals and aluminum heads. Use a dedicated downstream injector or hand-pump sprayer instead.

  6. Can I plug a 15 A washer into a 20 A circuit?
    Absolutely; the extra 5 A provides cushion for startup surges and accessory tools without tripping breakers.

  7. Do I need a water softener for spot-free rinses?
    If your TDS exceeds 150 ppm, an inline RV water softener or CR Spotless de-ionizer will eliminate mineral rings and cut drying time.

  8. Should I remove the spray gun before storage?
    Yes—trigger locks can compress internal seals. Detach, hang the wand vertically, and store nozzles in a sealed bag to prevent grit ingress.

  9. What maintenance adds the most life for the least money?
    Flush with clean water 30 seconds after each use and replace the ¾” garden-hose washer every six months—90% of pump failures trace to debris.

  10. Can I run two machines off one hose bib?
    Only if household pressure exceeds 60 PSI and you install a Y-valve with individual shut-offs; expect 10–15% flow loss on each unit.
