If you are looking for the best worx 20v 320 psi cordless pressure washer, this page covers one model: the WORX WG620.9 cordless Hydroshot portable power cleaner, ASIN B08B4M2KTX. The listing says the unit delivers up to 320 psi at a maximum of 0.53 gallons per minute, and that it is sold as a bare tool. The battery and charger are not included. The listing says the unit can draw water from a garden hose, a pool, a lake, a bucket or a 2-litre bottle. The data here is a saved listing record dated 2026-10-23.
Quick answer
- The listing describes a 20V portable power cleaner rated at 320 psi and a maximum flow of 0.53 gpm.
- The listing says it is a bare tool. The battery and charger are not included, so the purchase is the unit alone.
- The listing points to Power Share batteries as the match. It does not name the battery models that work with the unit.
- The listing does not state a warranty, a runtime or the manufacturer’s warranty terms. Ask the seller before you buy.
The product at a glance
The table lists only what the saved listing record states. Where the listing is silent, the cell says “not stated”. Pressure, flow and the battery situation matter most for this tool. In this table, psi is pounds per square inch, the unit of pressure, and gpm is gallons per minute, the unit of flow.

Who it suits
It suits a person who already owns WORX Power Share batteries and a charger, and who wants a power cleaner without buying a second battery. The listing says to “use the batteries from your existing Power Share tools.” It does not name which battery models fit, so check the label on your battery against the listing before you assume it works.
If you own no WORX batteries, the bare tool means a second purchase. The listing does not describe the battery or charger you would need to buy, so that purchase is open until the seller answers.
It also suits a person who cleans away from a spigot. The listing says the unit “draws water from any fresh water source like a pool, lake, or bucket,” and that a bottle connector lets you hook up a 2-litre bottle. Using the listing’s own figures, 2 litres is about 0.53 US gallons, the same as the stated maximum flow of 0.53 gpm. A full 2-litre bottle therefore holds about one minute of flow at the listed maximum. This is arithmetic from the listing, not a stated runtime.
The listing gives the weight as 2.82 kg, which is about 6.2 pounds. That is light enough to carry around a yard, and the listing says the unit can clean “all your outdoor spaces and gear.” The listing does not name the surfaces it is best on, so treat that phrase as the listing’s own claim.
The listing also describes a multiple spray nozzle that lets you switch between varying degrees of water stream intensity, so the same unit covers both cleaning and watering. The nozzle setting is the only stream control the listing describes.
Skip it if
- You do not own a WORX 20V battery and charger and do not want to buy them separately. This package is a bare tool, and the listing does not say which battery or charger to buy.
- You need more flow than the 0.53 gpm maximum the listing gives. The listing does not give a higher flow figure for this model.
- You need a stated warranty before you buy. The listing does not state one.
- You need the pressure and flow figures explained for a specific task. The listing gives maximum figures and does not describe the conditions behind them.
- You want a single fixed stream. The listing describes a nozzle that changes stream intensity and does not describe a fixed-stream option.
What the listing does not say
The listing is clear that the battery and charger are missing. It is less clear about everything that comes after the purchase.
- Battery and charger. The listing says “Battery & Charger Not Included” and “the battery and charger are not included.” It does not name a battery model or a charger model.
- Compatible batteries. The Power Share claim names no battery model and no tool list.
- Runtime and charge time. Neither is stated.
- Tank volume. The listing gives 2 liters as a tank volume but does not say whether that is the water tank or the size of the bottle used with the bottle connector.
- Warranty. Not stated.
- Manufacturer. The brand is WORX, and the listing names Positec Technology (China) Co., Ltd as the manufacturer. The listing does not explain the relationship between the two names.
- Detergent and water temperature. The listing does not mention detergent use or the water temperatures the unit handles.
If you need a battery and charger in the same purchase, the WORX hedge trimmer battery and charger post covers that question for a different WORX tool. For the battery voltage question in general, the guide to lawn mower battery voltage and amps explains what voltage and amp-hour figures mean.
Buying checklist
- Check your current battery against the Power Share claim. The listing names no battery model, so the label on your battery is the only match check you have.
- Pick the water source before you order. The bottle option needs the included WA4038 bottle connector, and the other sources use the included draw hose or quick-connect adapter.
- Plan the flow for the job. At 0.53 gpm, a 5-gallon bucket would empty in about 9.4 minutes (5 divided by 0.53). That is arithmetic, not a stated runtime.
- Ask for the warranty terms in writing. The listing states no warranty.
- Look over the draw hose and the quick-connect adapter for wear before the first use.
Mistakes to avoid
- Assuming the bottle connector gives you unlimited water. A 2-litre bottle holds about 0.53 gallons, which is about one minute at the listed maximum flow.
- Buying the bare tool and expecting a battery to be included. The listing highlights “Battery & Charger Not Included”.
- Aiming the nozzle at another person. The University of Kentucky page says never to point the sprayer at another person, whether the pressure washer is operating or not.
- Assuming the 320 psi figure applies at every nozzle setting. The listing gives it as a maximum, and the nozzle changes the stream intensity.
- Buying a different battery line by mistake. The listing ties the unit to Power Share batteries and names no other battery line as a match, so a battery from another line needs its own check against the listing.
How we chose
This post covers one product: ASIN B08B4M2KTX, listed as the WORX Cordless Pressure Washer, 20V 320 PSI Power Washer, WG620.9. The keyword names this exact model, so no other model is compared here. The data is the saved listing record dated 2026-10-23 (CHECKED), limited to the title, bullets and specs. Seller details, ratings, availability and images are not part of this post.
The model is in the post because the keyword names it, and because the listing gives the figures a buyer needs to judge the bare-tool package: battery status, the water sources, the flow and pressure maximums and the included accessories. Where a figure is missing, the table or the sentence says so.
The two non-retail sources are a University of Kentucky page on pressure washer safety and an agricultural safety page from extension.org on stored-energy hazards. They are used for safety rules that apply to any pressure washer, not for facts about this WORX model.
The fields checked were the title, brand, model number, item type, battery and charger status, power source, maximum pressure and flow, tank volume, hose length, included components, weight, dimensions, manufacturer and the bullet text. The listing states the pressure and flow maximums, the hose, the included parts and the battery status. It is silent on warranty, runtime and the battery models that fit, which a buyer needs before ordering.
What we could not verify
- The 320 psi and 0.53 gpm figures are maximum figures stated in the listing. None of the sources opened for this post checks them for this model.
- The battery models that work with the unit are not named, and the Power Share claim is not confirmed by any source opened for this post.
- The warranty, runtime and charge time are not in the listing.
- The listing does not say whether the 2-liter tank figure refers to the water tank or to a bottle.
- The listing names WORX as the brand and Positec Technology (China) Co., Ltd as the manufacturer. This post does not determine which company stands behind any warranty, because the listing states none.
- The sources do not describe this WORX unit, so they are used only for general pressure washer safety.
FAQ
Does the WORX 20V pressure washer come with a battery or charger?
No. The listing describes the package as a bare tool and says the battery and charger are not included. You need to supply both, or buy them separately, before the unit can run on battery power.
Can I use my existing WORX batteries?
Power Share is the battery line the listing names. It names no battery model, so compare the label on your own battery with the listing before you assume it fits. If the label shows a different platform, the listing gives no basis for using that battery with this unit.
Can it draw water from a bucket or a bottle?
Yes, according to the listing. It says the unit draws water from any fresh water source like a pool, lake or bucket. It also says a bottle connector lets you hook up a 2-litre bottle with a standard mouth, so a bottle is a practical source when no spigot is nearby.
How much flow does it give?
The listing gives a maximum flow of 0.53 gallons per minute. Using the listing’s own figures, a 2-litre bottle holds about 0.53 US gallons, so a full bottle equals about one minute at that maximum. The listing does not state a runtime, so treat this as arithmetic rather than a stated figure.
What comes in the box besides the unit?
The listing names a 5-in-1 nozzle, a 20-foot draw hose, a WA4038 bottle connector and a WA4017 quick-connect adapter. The battery and charger are not in the list, so the box is the unit and its accessories only.
What safety rules apply to this pressure washer?
The University of Kentucky page advises reading the operator’s manual, never pointing the sprayer at another person, and keeping the water away from electrical equipment. The Ag Safety page advises examining hoses and fittings before use, and never aiming a pressure-washer nozzle toward a person.
Bottom line
Buy this WORX model only if you already own a WORX Power Share battery and charger, or you plan to buy them, and 0.53 gpm is enough for the cleaning you have in mind. If you need the battery and charger in the box, a higher flow figure or a stated warranty, choose a kit whose listing states them.
