Spring is here. Your driveway is covered in moss, your siding is green with algae, and your deck looks gray.
You need a pressure washer.
But walking into the hardware store is confusing. Do you buy the cheap, quiet Electric model? Or do you shell out for the loud, heavy Gas beast?
In the past, electric washers were weak toys. But in 2026, Brushless Motor technology has closed the gap. We tested the top models to help you decide which machine belongs in your garage.

1. The Homeowner’s Choice: Sun Joe SPX3000 Electric
For 90% of homeowners, this is the only machine you need. It is the #1 bestseller on Amazon for a reason.
Why It Wins: It’s incredibly easy. You plug it in, attach the hose, and pull the trigger. No pulling a starter cord, no mixing gas, no oil changes.
The Power: At 2,030 PSI, it is strong enough to clean concrete, wash your car (safe for paint), and blast mildew off vinyl siding.
Total Stop System: The motor shuts off completely when you let go of the trigger. It’s silent until you need it.
The Verdict: If you just want to wash the car and the patio on weekends, buy this.
2. The Commercial Pro: Simpson PowerShot PS3228 (Gas)
If you have a large driveway with oil stains or need to strip old paint off a deck, electric won't cut it. You need raw gas power.
The Upgrade: This isn't just a homeowner unit; it's a PowerShot. It uses a AAA Industrial Triplex Pump. Unlike cheaper "Axial" pumps that burn out after a few seasons, this pump is designed for daily, heavy-duty use.
The Engine: It runs on a Honda GX200. This is widely considered the most reliable small engine ever built. It starts on the first pull, every time.
The Power: At 3,300 PSI, it cleans concrete about 3x faster than an electric washer. It strips paint, grease, and gum effortlessly.
The Verdict: It costs more than the entry-level gas models, but with the Honda engine and Triplex pump, it will last 10+ years.
Critical Decision Guide: What Are You Cleaning?
1. Washing Cars & Windows (1,500 - 2,000 PSI)
Winner: Electric. Gas washers are too powerful and can strip the clear coat off your car or break window seals.
2. Cleaning Concrete Driveways (2,500+ PSI)
Winner: Simpson Gas PowerShot. Concrete is porous. To get oil and deep moss out, you need the high pressure (3,300 PSI) and high water flow (2.5 GPM) of a gas unit. An electric washer will work, but it will take you 2–3 times longer to clean the same area.
3. Cleaning Wood Decks (1,800 - 2,200 PSI)
Winner: Electric. Wood is soft. If you hit it with 3,000 PSI gas power, you will scar the wood and cause splinters. Electric gives you a safer, controlled clean.
Final Verdict: Which One Should You Buy?
Buy the Sun Joe Electric If:
You mainly wash cars, patio furniture, and windows.
You want a machine that starts instantly with zero maintenance.
You have close neighbors (it’s quiet).
Buy the Simpson PowerShot Gas If:
You have a large Concrete Driveway or Brick Patio that requires deep cleaning.
You need to strip paint, remove oil stains, or clean the second story of a house.
You want a Honda Engine that will last 10+ years.

Frequently Asked Questions (FAQ)
Q: Can I wash my car with a gas pressure washer?
A: No. Gas pressure washers typically operate at 3,000+ PSI, which is strong enough to strip the clear coat paint, peel decals, and dent plastic bumpers. For cars, always use an Electric Pressure Washer (1,500–2,000 PSI) with a dedicated "Foam Cannon" or "Wide Fan Tip" (40-degree nozzle).
Q: Do electric pressure washers work for driveways?
A: Yes, but they are slower. An electric washer (2,000 PSI) can clean concrete, but it moves less water (GPM) than a gas unit. To clean a large driveway efficiently, you need a gas washer (3,000 PSI) paired with a Surface Cleaner attachment. An electric washer will take 2–3 times longer to clean the same area.
Q: How often do I need to change the oil in a gas pressure washer?
A: You should change the engine oil after the first 5 hours of use (break-in period), and then every 50 hours or once per season after that. Electric pressure washers require zero oil changes or engine maintenance.
Q: Can I use hot water in my pressure washer? A: No. Most residential pressure washers (both gas and electric) are designed for Cold Water only. Running hot water from your tap through the pump can overheat the seals and destroy the machine. If you need hot water (to melt grease), you must buy a specialized "Hot Water Pressure Washer" which costs $2,000+.
