Pressure Washer Prices Plummet on Prime Day
Pressure washers are one of those tools you do not know you need until you own one. I bought a Sun Joe SPX3000 on Prime Day 3 years ago for $119. Regular price was $179. That washer has cleaned my siding, my driveway, my fence, my car, and my deck. Best $119 I ever spent on yard tools.
The prices below are current. When Prime Day starts, they will drop. Some by $30. Some by $60. The popular models like the Sun Joe SPX3000 sell out fast. I will tell you exactly which ones to watch.

1. Sun Joe SPX3000 — Amazon’s Best-Selling Pressure Washer
Over 70,000 reviews. 4.5 stars. The Sun Joe SPX3000 is the most popular pressure washer on Amazon for a reason. At $179 today, it delivers 2030 PSI and 1.76 GPM. On Prime Day, I have seen it drop to $129. That is a $50 savings on a proven machine.
It comes with five quick-connect nozzles: 0-degree, 15-degree, 25-degree, 40-degree, and a soap tip. The dual detergent tanks let you switch between two soaps without refilling. The total stop system shuts off the motor when you release the trigger. That saves energy and extends pump life. A 20-foot hose and 35-foot power cord give you good reach.
2. Greenworks GPW1501 — Best Budget Pressure Washer
The Greenworks GPW1501 costs $99 right now. On Prime Day it often drops to $69. For that price, you get 1500 PSI and 1.2 GPM. That is enough to wash cars, clean patio furniture, and spray down the deck. It is not a driveway cleaner. For big concrete jobs, you need more power.
This is the perfect starter pressure washer. It weighs just 17 pounds. You can carry it around with one hand. The 20-foot hose and 35-foot cord give decent range. Greenworks includes a soap applicator bottle. Fill it with car soap or deck cleaner and spray away. If you have never owned a pressure washer, start here.
3. AR Blue Clean AR383 — Best Mid-Range Electric
The AR Blue Clean AR383 sits at $149 and delivers 1900 PSI at 1.5 GPM. This is the sweet spot for most homeowners. Enough power to clean the driveway but gentle enough for the car. The Italian-made pump is the standout feature. AR pumps last longer than the Chinese pumps on cheaper models.
This washer comes with a 20-foot hose and a hose reel that actually works. Most cheap hose reels jam. This one does not. The wheels are large enough to roll over grass and gravel. The built-in detergent tank holds enough soap for a full car wash. If you want one pressure washer that does everything, this is it.
4. Karcher K1700 — The Premium Electric Pick
Karcher is the brand professionals trust. The K1700 at $129.99 delivers 1700 PSI and 1.3 GPM. The build quality is a step above Sun Joe and Greenworks. The N-Cor pump is non-corrosive and maintenance-free. Karcher claims it lasts 3 times longer than standard pumps.
The unique feature is the three-piston axial cam pump. Most electric washers use wobble pumps. The axial cam pump delivers smoother pressure with less pulsing. The 25-foot high-pressure hose is longer than most at this price. The two detergent tanks sit on the top for easy access. If you want a pressure washer that lasts 10 years, buy the Karcher.
5. WHOLESUN 3500PSI — Best High-Power Electric
The WHOLESUN 3500PSI pressure washer is the most powerful electric model on this list. At $199.99 today, it pushes 3500 PSI and 2.6 GPM. That rivals small gas pressure washers. Prime Day could bring this under $150. If it does, jump on it.
This washer comes with a 20-foot hose, four nozzles, a soap tank, and a turbo nozzle. The turbo nozzle spins water in a circle for faster cleaning. It cuts cleaning time by half on driveways and sidewalks. The wheels and handle make it easy to pull around. For the price, the power output is hard to beat.
6. Simpson MSH3125-S — Best Gas Pressure Washer Deal
If you need gas power, the Simpson MSH3125-S is the one. At $369 today, it delivers 3200 PSI and 2.5 GPM from a Honda GC190 engine. Honda engines are the gold standard. They start on the first pull and run for years with basic maintenance.
This is a real pressure washer. It strips paint. It cleans 2,000 square feet of concrete in 30 minutes. The 25-foot hose is kink-resistant. The 10-inch pneumatic tires roll over rough ground. This washer weighs 68 pounds. You are not carrying it. You are rolling it. If you have a big property or you do serious cleaning work, buy the Simpson.
7. Stanley SHP2150 — Best Value Under $100
The Stanley SHP2150 costs $89.99 today. It claims 2150 PSI and 1.4 GPM. The real-world PSI is lower, maybe 1700 to 1800. But for under $100, it still cleans cars, RVs, boats, and patio furniture well. The foam cannon attachment is a nice bonus at this price.
This washer is small and light at 21 pounds. It stores on a shelf in the garage. The 20-foot hose is short. You will want a longer aftermarket hose. The built-in wheels are tiny and not great on grass. But for the price, build quality surprises. Stanley is a name brand that stands behind their products.
Electric vs Gas Pressure Washers: What Prime Day Teaches You
I have owned both. Electric pressure washers cost less to buy and almost nothing to run. No gas. No oil changes. No winterizing. Plug it in and go. They max out around 2000 to 3500 PSI. That handles car washing, deck cleaning, and light driveway work.
Gas pressure washers start at $300 and go up. They hit 3000 to 4000 PSI and 2.5 to 4.0 GPM. More water flow means faster cleaning. Gas washers strip paint and blast stains out of concrete. They also need maintenance and make noise. For most homeowners, electric is the right call. The Prime Day deals on electric washers are usually better too.
Frequently Asked Questions
What PSI do I need for a pressure washer?
For cars and light cleaning, 1200 to 1900 PSI works. For decks and fences, 1900 to 2800 PSI is good. For driveways and heavy concrete work, you want 2800 PSI or more. Higher PSI is not always better. Too much pressure damages wood and strips paint by accident.
What is more important, PSI or GPM?
GPM matters more for cleaning speed. GPM measures water flow. Higher GPM means you rinse faster and clean bigger areas in less time. A 2000 PSI washer with 2.5 GPM cleans faster than a 3000 PSI washer with 1.5 GPM. Always check the GPM number.
Do I need a gas or electric pressure washer?
Electric covers 95 percent of homeowner needs. It is quieter, cheaper, and needs no maintenance. Gas makes sense only if you have a large property, you need to run the washer for hours, or you do heavy commercial cleaning.
Can I use a pressure washer to clean my house siding?
Yes, but use a 25-degree or 40-degree nozzle and keep the wand at least 3 feet from the siding. Too much pressure or too close damages vinyl and forces water behind the siding. Never spray upward into the siding. Water runs down behind it and causes mold.
