Ease of Use:



Remaining Thoughts

An awesome cordless cleaner/strain washer that you simply’ll certainly need to own.

General Score


WORX kindly offered me with their HydroshotTM Portable Pressure Cleaner (Model WG644). Based mostly on the product’s PSI (kilos per sq. inch) supply, WORX decided to name it a strain “cleaner.”  Whether you name it a cleaner or a washer, WORX designed a powerful cordless strain cleaner/washer system that gives a nice combination of power, efficiency, and utility.

For the aim of this evaluate, I confer with it as a strain washer, since most individuals consider a high-pressure water sprayer as a “pressure washer.”

In this video, Jack goes over the varied options of the WORX Hydroshot, together with the 2-battery system, the lance, and the adjustable nozzle. He also exhibits the product in use, each when utilizing a garden hose and the included hose that siphons water from a bucket. Test it out to see the product in use and to listen to Jack’s thoughts on this progressive product.


The unit arrived in a plain cardboard field with no markings on the field, except a emblem. The unit got here packaged with the motorized power head, lance (wand), multi-spray nozzle, 20-foot suction hose, two 20-Volt (2 Ah) batteries, twin 120-Volt battery charger, quick connector adaptor, plus a set-up and operations guide. The packaging protected the strain washer properly—it arrived with no dent or a mark on it.

The packaging protected the product properly.


First, the strain washer is cordless. Powered by twin “Power Share” 20 Volt Lithium-Ion batteries, the unit wants no cords, making use a breeze. No tangled cords, no issues with caught cords, and no cords to coil up for storage make the unit very handy to use. Together with the cord-free function, the unit is environmentally-friendly. In contrast to a gasoline powered strain washer, there’s no gasoline needed or carbon monoxide emitted. The HydroshotTM is protected to make use of indoors without any worry of dangerous fumes.

No hose connection? No drawback. The included 20-foot suction hose lets you use the gadget with a physique of recent water.

Plus, by buying an extra set of batteries, I stored the unit operating by swapping out a set of lifeless batteries for a set of absolutely charged ones. 40 volts provides the strain washer loads of power. The only nozzle with 4 spray patterns makes it straightforward to pick the facility that’s right for the job, without the fear of dropping separate/dedicated ideas.

Finally, the unit’s low profile (as soon as the lance/wand is removed from the motor section) makes for straightforward storage.


The HydroshotTM comes with a twin battery charging station. Because the unit consists of two 20 Volt Lithium-Ion batteries (see our article on Lithium-Ion batteries,) it is sensible to have a charger that accommodates both batteries on the similar time. That is notably useful to maintain a second set of batteries charged. With a second set of charged batteries all the time on standby, I’d save time as an alternative of ready for the batteries to cost.

The twin charging station ensures that both batteries are charged and ready for use.

When you plan on utilizing the HydroshotTM for long durations of time, I’d undoubtedly spend money on a second set of batteries.


Earlier than you do anything, cost the twin batteries. They’ll take round 2 hours to succeed in a full cost.

It’s as straightforward as plugging the charger into a 120-Volt wall outlet and sliding the batteries into the charger. WORX designed a fool-proof charging course of. The battery only slides in one method to cost. Retention clips on the again of the batteries make sure that they gained’t fall out of the unit when in use. Word that the clips don’t hold the batteries into the charger. To take away the batteries from the charger, I pushed them out of the charging station without holding the clip within the removing place.

When both lights on the charger change from flashing green to regular green lights, the batteries are absolutely charged. Time to get started!

First, I seemed at the instructions. With a mixture of easy-to-read diagrams and written sections, the superb directions make meeting and use of the HydroshotTM a breeze. Next, I headed outdoors. I grabbed the motor head, the lance (the wand that connects to the motor head), and the spray nozzle. I fixed the lance to the body of the motor assembly by inserting it into the motor head and twisting it until it locked into place. I inserted the nozzle into the top of the lance. It’s necessary to appropriately insert the nozzle and lock it in place. A very good tug on the nozzle (without it disengaging) advised me that I had achieved it appropriately.

After the batteries absolutely charged, I grabbed them and attached the remainder of the system. First, I related the fast connect coupler (provided) to the top of the backyard hose. You even have the choice of eradicating the male fast connect becoming from the underside of the HydroshotTM so that a normal garden hose becoming screws into the underside of the unit. After contemplating the extra work, I made a decision to use the adaptor, as it’s simpler and quicker general.

Subsequent, I inserted the batteries into the HydroshotTM. On both sides of the deal with, slide rails accept the Energy Share 20-Volt Li-Ion batteries. Installing both batteries is a snap, actually. I slid the batteries alongside the rail system (I might solely insert them a method) till I heard an audible “click” when the locking tabs engaged, making it unattainable for the batteries to fall out. Utilizing two Li-Ion batteries supplies an extended run time of the unit, in addition to the power to use a better strain. The system becomes a 40-Volt unit, not a 20-Volt one (which WORX additionally provides).

As soon as I installed the female quick connect coupling on the top of the hose, I slid it onto the male fast join on the underside of the HydroshotTM. Now I used to be able to turn on the water. I set the spray nozzle sample to 40 degrees. I then launched any air which may have accrued into the system by pulling the security lock button (situated on the top of the handle–it’s brilliant orange, you’ll be able to’t miss it), after which gently pulling on the activation lever (set off) – but just slightly (first stage of a two-stage set off). I needed the water to return out of the tip of the lance in a continuous stream without air bubbles earlier than beginning the engine. Now, I used to be ready to attempt the unit.

On prime of the motor head of the HydroshotTM (simply behind the lance) is a selector change that provides the choice of blasting at a power of 290 PSI or 450 PSI.

My moldy concrete walkway offered the right check for the HydroshotTM.  I set the spray nozzle to 150 levels. I disengaged the security lock button and pulled the set off to its second stage, which turned on the unit. When pulling the set off, only two speeds are available: water calmly spaying out the nozzle or full-throttle by activating the water pump. The unit sprang to life once I pulled the set off to the complete “ON” position. Instantly, I heard the motor kick in, and a blast of high-pressure water exited the nozzle. Time to put the HydroshotTM by means of its paces.


The mould on the concrete walkway was no match for the HydroshotTM. I began on 290 PSI and a nozzle spray angle of 150. The setting removed the mould, nevertheless it took a while. I stored the nozzle head close to the concrete floor to wash. I then powered as much as 450 PSI using the identical spray angle. Instantly, I noticed a direct distinction. On the larger strain and concentrated spray angle of 150, the strain washer blasted the mould off the concrete. I tried totally different spray patterns, from 00 by means of 400. My most-used spray sample (to wash the concrete walkway) was 150. Each PSIs prove helpful for different purposes. 290 PSI appears better-suited as a cleaning device and 450 PSI, from my perspective, works nicely as a strain washer.

Though WORX named the unit the HydroshotTM Portable Power Cleaner, I think about it within the class of a strain washer. With a 150 spray pattern and a high 450 lb. power setting, I removed paint from a bit of outside furniture. Conversely, the two-stage trigger allows me to tug calmly without partaking the motor to mist crops or water them. (The 400 sample proved the simplest and least invasive.) With slightly apply, I adjusted the pull to expertly water crops or to strain wash.


WORX designed the HydroshotTM unit to be used even and not using a commonplace backyard hose or water supply. Included with the unit is a nifty 20-foot-long hose with a fast connect on one end and a water filter and float on the other finish. The consumer drops the intake right into a bucket of water, river, lake, or any fresh-water supply. The Styrofoam® – like float at the end of the water intake retains the intake above the underside of the water source, stopping mud or gunk amassed at the bottom from clogging the intake. A cage filters out huge debris from the consumption and a smaller display removes further detritus. But the float keeps the consumption out of the actually wonderful silt or particles which will clog the nozzle. Additionally out there is an adaptor that connects a two-liter water bottle to the HydroshotTM.

I really like the portability of the HydroshotTM. The unit works perfectly for once I don’t have a direct water line hook-up. I can wash my automotive, bicycle, boat, home windows, outside furniture—it doesn’t matter if a garden hose is close by. The amount of water obtainable does restrict how a lot cleaning gets completed, however the HydroshotTM solely sips zero.9 gallons of water per minute–and that’s at the high setting of 450 PSI. No specs point out the water utilization for 290 PSI, but I think about it’s significantly less than at 450 PSI.


Two last technical notes on the 20-foot hose. First, the hose lifts a column of water only 5 ft. You’re not going to work from a ladder and reach excessive places utilizing the hose. As an alternative, the hose gives the pliability to work in an approximately 20-foot radius of the water source, whereas preserving the unit no larger than my shoulders. (I’m 6 ft tall.)

Second, it’s helpful to prime the hose (fill it with water) earlier than utilizing it with the HydroshotTM. The facility washer’s pump works more efficiently when the hose is primed.


It relies upon. I tested a number of situations. I ran the unit constantly on excessive energy with a 400 spray sample. At that energy and sample, the batteries lasted 15 minutes. But I wouldn’t normally use the HydroshotTM constantly. As an alternative, I’d sometimes work on an area, take a break and move to a unique strategy angle, or cease to move an item and expose a new space to wash. Perhaps I’d use it constantly when eradicating mould on a concrete sidewalk or when cleaning a deck. For most purposes, though, it’s a stop-and-start process, which lengthens the battery time.

Let’s additionally keep in mind that this can be a 40-Volt battery-powered, cordless software. Positive, if I ran the unit from a automotive battery, I’d obtain more run time–however how sensible is that? WORX properly married a 40-Volt Lithium-Ion system with a transportable, light-weight, powerful, sensible strain washer. If I would like more continuous work outing of the unit, I’ll spend money on a second set of batteries and maintain them absolutely charged to use when the primary set dies.

With any energy device, it’s all the time advisable to wear safety glasses. Pressure washers are not any exception. We advocate the Wiley-X Brand. Pressure washers can generate flying debris, as well as water bouncing off your eyes. Be protected.


I completely respect the WORX HydroshotTM.  It’s more than a cleaner. I contemplate it a low energy, full-fledge strain washer. Positive, at its low finish of 290 PSI and a sprig angle of 400, it lives up to the cleaner classification. However crank this baby as much as 450 PSI with a 150 spray pattern, and I had a strain washer in my arms–even one that stripped paint from furniture.

The unit’s light-weight design makes it straightforward for anybody to operate it. The four spray sample angles included into one head provides comfort in changing position. The hose that turns it into a totally moveable system the place solely a water source is required (no backyard hose and spigot) is pure genius. And the two-stage set off that gently waters crops with out damaging them offers a nice function.

For those who don’t need the facility of a full-fledged strain washer (fuel or electrical) and recognize the portability and lack of cords to tangle, you then’ll love the WORX HydroshotTM
