There's a whole industry built around pressure washer accessories, and half of it is junk you don't need. Gimmicky attachments, overpriced hoses, and gadgets that sound great in the product description but collect dust in your garage. Here are the accessories that actually make a difference, ranked by how much they'll improve your results.
1. Surface Cleaner (Buy This First)
If you only buy one accessory, make it a surface cleaner. It's a round attachment with spinning jets underneath that cleans flat surfaces evenly and without the zebra stripes you get from a standard wand.
The difference is dramatic. A two-car driveway that takes 90 minutes with a regular nozzle takes 30-40 minutes with a surface cleaner. And the results are more consistent because you're not trying to maintain perfect distance and speed by hand.
The Surface Cleaner Attachment is a solid choice. Make sure whatever you buy is rated for your washer's PSI. Undersized surface cleaners spin too fast and wear out quickly.
2. Foam Cannon
A foam cannon turns your pressure washer into a car-washing machine. It mixes soap and water into thick foam that clings to surfaces instead of running off immediately. That dwell time is what makes soap effective. Spraying soap through a regular nozzle doesn't give the detergent enough contact time to break down dirt.
The Tool Daily Foam Cannon is the one I recommend most. It's affordable, adjustable, and works with most electric and gas washers. The thick foam it produces is surprisingly satisfying to watch.
Beyond car washing, foam cannons are great for pre-treating house siding, fences, and decks before the main wash pass. Let the foam sit for 5-10 minutes, then rinse with your regular nozzle.
3. Turbo Nozzle
A turbo (or rotary) nozzle takes a zero-degree stream and spins it in a cone pattern. You get the cleaning intensity of a concentrated jet spread over a wider area. It's like having a 0-degree nozzle that's actually safe to use on concrete.
Where it shines: stubborn stains on driveways, oil spots, paint prep, and heavily soiled surfaces. It cleans 40-50% faster than a standard 25-degree nozzle on tough jobs.
Where to skip it: any soft surface. Wood, vinyl siding, painted surfaces, and cars. The spinning jet is still aggressive enough to damage these materials.
4. Extension Wand
A 36 to 48-inch extension wand lets you clean second-story siding, gutters, and high windows from the ground. This is a safety upgrade as much as a convenience one. Nobody should be climbing a ladder while holding a pressure washer wand.
Look for one with an adjustable angle head. Fixed-angle wands make it awkward to hit certain spots. An articulating head lets you direct the spray where it needs to go without contorting yourself.
5. Replacement Quick-Connect Nozzle Set
Most washers come with a basic nozzle set, but the included nozzles are often lower quality. Aftermarket brass or stainless steel nozzle sets last longer and maintain their spray patterns better.
A full set (0, 15, 25, 40, and 65-degree) runs about $15-25. Cheap insurance against the included plastic nozzles cracking or losing their shape after a season of use.
What to Skip
- Gutter cleaner attachments: Sounds useful in theory, but most are flimsy, hard to aim, and spray more water on you than in the gutter. A blower and a ladder are still faster.
- Sandblasting kits: Consumer-grade wet sandblasters attached to pressure washers are inconsistent and messy. If you need to sandblast something, rent a proper unit.
- Ultra-long hoses (100+ feet): Every foot of hose reduces your effective PSI. By the time water travels 100 feet, you've lost noticeable pressure. Keep your washer closer to the work area instead.
- Undercarriage cleaners: The concept is good, but most of these roll around under your car unpredictably and don't clean as well as just angling a standard wand.
Build Your Kit Over Time
You don't need everything at once. Start with a surface cleaner and a foam cannon. Those two accessories cover 80% of what most people need. Add a turbo nozzle when you have a tough job coming up, and grab an extension wand when you're ready to tackle the second story.
Quality matters more than quantity. A $40 surface cleaner from a reputable brand beats a $15 off-brand that falls apart after three uses. Invest in the things you'll use regularly and skip the novelty items.
