If you’re stuck choosing between the WORX Hydroshot 20V and 40V, here’s the deal: both work well, but they serve different jobs. The 20V Hydroshot is great for easy tasks like washing your car or patio chairs.
The 40V is stronger. It’s better for tough work, like cleaning siding or getting grime off your driveway. I’ve used both in my Midwest yard. Trust me—power matters more than you’d think when mud sticks after a storm.

Quick Overview: WORX Hydroshot 20V vs 40V at a Glance
Want the short version? Here it is. The 20V Hydroshot is great for light jobs—like rinsing your car or spraying patio chairs. The 40V Hydroshot has more power. It’s better for cleaning decks, siding, and driveways.
Here’s a quick side-by-side look based on my use:
| Feature | WORX Hydroshot 20V | WORX Hydroshot 40V |
| Max Pressure | 320 PSI | 450 PSI |
| Max Flow Rate | 0.5 GPM | 0.9 GPM |
| Weight (with battery) | 8.2 lbs (approx.) | 7.3 lbs (approx.) |
| Battery Setup | One 20V 4.0Ah battery | Two 20V 2.0Ah (40V total) |
| Best For | Cars, bikes, furniture | Decks, driveways, siding |
TL;DR:
Use the 20V for simple cleaning around the house.
Go with the 40V if you need more strength for outdoor messes—even if it’s a bit heavier and costs more.
Understanding the Power Difference
When you see “20V” or “40V,” that’s about the battery.
The 20V Hydroshot uses one small battery. It’s light and easy to carry.
The 40V uses two 20V batteries at once. This gives it more power.
Here’s what that means when cleaning:
- The 20V gives you 320 PSI and 0.5 GPM. That works well for dirt, dust, and light rinse jobs.
- The 40V gives you 450 PSI and 0.9 GPM. That extra boost helps with stuck-on mud or green slime on wood.
After a storm, I noticed the 40V really made a difference on my deck and driveway.
My Personal Experience with Both Models
I live in the Midwest and use both models in my yard.
The 20V is my go-to for light stuff—like cleaning the car or spraying off patio chairs. It’s fast and not too heavy. Great for weekends.
The 40V comes out when I need real cleaning power. I’ve used it for mold on siding and dirt on deck boards. It’s much stronger than a garden hose.
What I’ve Noticed:
- The 20V is lighter and easier to grab and use.
- The 40V lasts longer under heavy use but feels heavier.
- Both use WORX Power Share batteries—so if you have other WORX tools, you can swap batteries. That’s a plus!
Ergonomics & Ease of Use: Weight, Size, and Handling
Switching between the WORX Hydroshot 20V and 40V, I noticed one thing right away—the weight matters.
The 20V feels light in your hand. I can use it for 15 to 20 minutes without my arm getting tired. It’s great for washing the car or spraying off chairs.
The 40V is heavier. That’s because it uses two batteries. After 10 minutes, I start to feel it in my wrist and shoulder—especially when I’m reaching up to clean siding.
Apartment vs. House Portability
If you live in an apartment or condo, go with the 20V. It fits in small closets and is easier to carry to a balcony or shared parking spot.
If you live in a house with a yard or garage, the 40V makes more sense. It handles bigger jobs, like decks or long driveways where your hose won’t reach.
Battery Runtime and Charging
- The 20V runs about 15–20 minutes per charge with medium use. Charging the 4.0Ah battery takes around 5 hours.
- The 40V uses two 2.0Ah batteries. It runs for about the same time but lasts longer under pressure. Charging both on the dual charger takes about 2–3 hours, which is much faster.
Cost Breakdown: Price vs. Long-Term Value
At first, the 20V Hydroshot feels like the better deal. It costs less and works well for basic jobs. The kit usually comes with one 4.0Ah battery.
The 40V Hydroshot costs more—about $50 to $100 more based on what I’ve seen at stores like Amazon or Home Depot in the U.S. But it comes with two batteries and more cleaning power.
The WORX Power Share Bonus
If you already own WORX tools, the Power Share system is a big win. I use their trimmer and blower, so I swap batteries across tools. This saves money and cuts down on clutter. For many U.S. homeowners, that’s a huge plus.
My Take on Long-Term Value
If you only need light cleaning, the 20V is perfect.
If you already own other WORX tools or plan to get more, the 40V is a smart buy. It’s stronger, and the batteries are more flexible. I see it as a better investment over time.
Accessory Compatibility & Flexibility
People often ask: Do both models use the same parts? Here’s what I’ve found:
Nozzle System
- The 20V comes with a 5-in-1 nozzle. It offers more spray choices, including a soft spray I sometimes use on plants.
- The 40V has a 4-in-1 nozzle. It has fewer modes, but it’s faster to change settings when I’m doing big jobs.
Add-Ons I Use Often
- Bottle Adapter – Great when I don’t want to drag a hose. I use it to clean bikes or rinse gear at the park.
- Turbo Nozzle – Adds a spinning spray. It works really well on driveways.
- Brush Attachments – I don’t use these much, but for siding or boats, they save time and effort.
Pro Tip for U.S. Buyers
If you shop at Home Depot, Lowe’s, or Amazon, look for bundle deals. Sometimes, you get the Hydroshot plus extra parts—like nozzles or brushes—for a better price.
When to Choose 20V vs. 40V: Easy Decision Guide
Still stuck between the WORX Hydroshot 20V and 40V? Here’s a quick guide I give my friends when they ask which one fits their needs.
Pick the 20V Hydroshot if:
- You live in an apartment or small house.
- You mostly do light jobs—like washing your car, bike, or patio chairs.
- You want a lighter tool that’s easier on your wrist or shoulder.
- You’re on a budget or don’t want extra batteries or chargers.
Pick the 40V Hydroshot if:
- You live in a house with a yard, deck, or siding that needs cleaning.
- You deal with mud, algae, or thick grime.
- You already use WORX 20V tools and want to swap batteries.
- You don’t mind a little more weight for extra power.
Avoid the 40V if:
- You live in an apartment and only clean once in a while.
- You’re on a tight budget, unless you already own WORX batteries.
- You need something very light, especially if lifting is hard for you.
Who Gets the Most Out of the 40V:
- U.S. homeowners with big patios, wooden decks, or long driveways.
- RV or boat owners who want a solid clean without using a big pressure washer.
- DIY fans who want one tool for both light and heavy jobs.
Final Thoughts
After using both in my Midwest yard, here’s my take:
- The 20V Hydroshot is best for light jobs. It’s quick, easy to carry, and great for smaller messes.
- The 40V Hydroshot gives you more power. It’s heavier and costs more, but it handles tougher cleanups like siding, decks, and driveways.
Bottom line: Think about what you clean most often. If I had to pick one, I’d choose the 40V—just because of the extra power.
But lots of people I know are totally happy with the lighter 20V for daily use.
