Our pick

Choose the EGO HPW2105 for shorter remote washing jobs where you can carry clean water and a charged battery. Its kit includes a filtered siphon hose, a 6.0 Ah battery and charger. Choose the HPW3204-2 when the job calls for its higher pressure output and two-battery setup. In either case, plan the water supply before relying on the battery-runtime headline.
Choose a bucket-fed pressure washer for places without a tap. Compare EGO siphon kits, battery contents and how much water a remote wash needs.

What matters in practice
Choose a documented siphon-capable kit, then calculate the water needed for actual trigger time.
At an illustrative 1.2 GPM draw, five gallons gives about 4.2 minutes of continuous trigger time. Ten minutes at that flow would need 12 gallons. Both examples assume the selected mode delivers 1.2 GPM and ignore pauses. They show why a full-car wash and a quick rinse of a muddy item are different remote jobs.
EGO claims up to 30 minutes for the HPW2105 with its included six-Ah battery and up to 60 minutes for the HPW3204-2 with two included six-Ah batteries. Those are separate manufacturer runtime claims. They do not establish that maximum pressure, a particular flow and maximum runtime occur together.
HPW2105 includes the battery and charger, while HPW2100 is the tool-only configuration. The HPW3204-2 includes two batteries and a charger, while HPW3200 is bare-tool. Check the exact suffix and selected Amazon option. A cheaper bare-tool listing is only useful if you already have the required compatible batteries and charging setup.
The included siphon arrangement is documented for fresh water. Keep the intake filter fitted and follow the priming, source-height and operating instructions in the supplied guide. A battery removes the outlet requirement, but it does not make dirty water, an inadequate reservoir or an unsuitable drain location acceptable. Keep children and pets clear of the work area.
2 options

EGO, HPW2105
A single-battery compact washer with bucket siphoning, quick connections and an included foam cannon for cordless cars, furniture and smaller outdoor jobs.
Winner whenCompact cordless cleaning and siphoning
Its 2100 PSI and 1.2 GPM figures are maxima, and the single-battery platform cannot match the HPW3204-2 on sustained heavy cleaning.

EGO, HPW3204-2
The strongest cordless option in this set, with dual batteries, selectable modes and a siphon hose for cleaning where outlets or taps are inconvenient.
Choose instead whenYou need the larger unit's documented 3,200 PSI at 1.2 GPM working point and can manage its two-battery kit and water supply.
Turbo mode requires both supplied batteries, and sustained high-output runtime is much shorter than the up-to-60-minute Eco figure.
