Which pressure washer is best without an outdoor tap
Top pick
EGO Power+ 2100 PSI Compact Pressure Washer Kit
The EGO HPW2105 suits shorter remote washing jobs where you can carry clean water and a charged battery. Its kit comes with a filtered siphon hose, a 6.0 Ah battery and charger. When the job calls for the higher pressure output and two-battery setup, go with the HPW3204-2. Either way, plan the water supply before you rely on the battery-runtime headline.
Why it suits this job
- Clear support for siphoning from a clean container
- How much water you have
- The catch
- The 2100 PSI and 1.2 GPM numbers are peak values. On sustained heavy cleaning, a single battery cannot keep up with the HPW3204-2.
- Go with EGO Power+ 3200 PSI Cordless Pressure Washer Kit if
- The larger unit's documented 3,200 PSI at 1.2 GPM working point is what you need, and you can handle its two-battery kit and water supply.
More reasons we picked it
- A battery and charger that come in the exact kit
- Needed pressure and surface safety

Decision guide
How to choose for this job
Start from a kit with documented siphon capability, and then work out the water needed for your actual trigger time.
Five gallons in a bucket runs out quickly
Take an illustrative draw of 1.2 GPM. Five gallons then gives about 4.2 minutes of continuous trigger time, and ten minutes at that flow would need 12 gallons. Both examples assume the selected mode delivers 1.2 GPM and leave out pauses. They show why washing a whole car and giving a muddy item a quick rinse are different remote jobs.
More battery runtime does not mean more water
For the HPW2105 with its included six-Ah battery, EGO claims up to 30 minutes, and for the HPW3204-2 with two included six-Ah batteries it claims up to 60 minutes. Those are separate manufacturer runtime claims. They do not show that maximum pressure, a particular flow and maximum runtime occur together.
Make sure the kit you buy is complete
The battery and charger come with HPW2105, and HPW2100 is the tool-only configuration. Two batteries and a charger come with the HPW3204-2, and HPW3200 is bare-tool. Check the exact suffix and the Amazon option you select. A cheaper bare-tool listing helps only if you already own the compatible batteries and charging setup it requires.
Stick to the water source the equipment is built for
Fresh water is what the included siphon arrangement is documented for. Leave the intake filter fitted and follow the priming, source-height and operating instructions in the supplied guide. A battery takes away the outlet requirement, but dirty water, an inadequate reservoir or an unsuitable drain location are still not acceptable. Keep children and pets clear of the work area.
What this page can’t tell you
- The refill calculation is only an illustration. It is neither a measured runtime nor a guaranteed wash duration.
- Nothing here claims a head-to-head test of battery life or cleaning speed.

The top pick and the alternatives
EGO, HPW2105
Power+ 2100 PSI Compact Pressure Washer Kit
Compact and single-battery, this washer siphons from a bucket, uses quick connections and comes with a foam cannon. Use it cordless on cars, furniture and smaller outdoor jobs.
Top pick ifSmall cordless jobs that need siphoning
Key facts
- Eco, High and Turbo modes, reaching up to 2100 PSI and 1.2 GPM
- One 56V 6.0Ah battery and a 320W charger come in the kit, with up to 30 minutes of claimed runtime
The catch
The 2100 PSI and 1.2 GPM numbers are peak values. On sustained heavy cleaning, a single battery cannot keep up with the HPW3204-2.
EGO, HPW3204-2
Power+ 3200 PSI Cordless Pressure Washer Kit
Of the cordless washers here, this is the strongest. It has dual batteries, selectable modes and a siphon hose, which helps when outlets or taps are out of easy reach.
Pick this instead ifThe larger unit's documented 3,200 PSI at 1.2 GPM working point is what you need, and you can handle its two-battery kit and water supply.
Key facts
- Maximum of 3200 PSI, with 1.2 GPM at pressure and 2.0 GPM maximum flow
- Two 56V 6.0Ah batteries come in the kit. EGO specifies up to 60 minutes in Eco mode
The catch
Both of the supplied batteries are needed for Turbo mode, and runtime at sustained high output is much shorter than the up-to-60-minute Eco figure.
