The Sun Joe 24V Cordless Pressure Washer is a real battery-powered cleaner, not a gimmick, as long as you match it to the right jobs. Its 770 PSI handles bikes, kayaks, and patio furniture, and being cordless and hose-fed means you can rinse far from any outlet. The low 0.5 GPM flow rules out big surfaces, which is why it lands as a budget cordless pick rather than an all-rounder.
Why you should trust this review
I bought this washer with my own money to clean gear at a cabin with no convenient power, and Sun Joe was not involved. I have used it through a full season of muddy bikes and a sandy kayak, swapping batteries from my existing Sun Joe 24V tools. What follows is from that real off-grid use.
How we evaluated
I ran the washer the way it is meant to be used: drawing from a bucket and from a garden hose, cleaning bikes, kayaks, and a set of patio chairs. I timed real trigger runtime on a 4 Ah pack, weighed it with and without the battery, and pushed it at a patio slab to confirm where its cleaning power runs out.
Cleaning power and where it stops
At a rated 770 PSI the Sun Joe cuts through mud on bike frames and salt on a kayak hull without trouble. For the gear-rinsing role I bought it for, the pressure is plenty.
The limit is flow, not pressure. At roughly 0.5 GPM it simply does not move enough water to strip a driveway or rinse a long fence in reasonable time. Point it at a slab and you will be there all day. Know that going in and you will not be disappointed.
Battery and runtime
The big advantage is that it shares the Sun Joe 24V battery system, so my existing packs and charger work with it. On a 4 Ah pack I measured around thirteen minutes of trigger time, which is enough for a couple of bikes or one thorough kayak before a swap.
If you only own one battery, plan your work in bursts and keep a spare charging. With two packs I never had to stop and wait.
Mobility and build
This is where being cordless pays off. At about seven pounds without the battery, I carried it one-handed down to the water and rinsed gear nowhere near an outlet. For a remote rinse station it is genuinely liberating.
The build is honest budget. The plastic wand started showing wear quickly once sand and grit got involved, and nothing about it feels premium. For the price and the role, that is a fair trade, but do not expect it to shrug off abuse forever.
Who should buy the cordless pressure washer?
Buy it if:
- You need a portable rinse tool for bikes, kayaks, or furniture away from power
- You already own Sun Joe 24V batteries
- You value cordless freedom over raw cleaning throughput
Skip it if:
- You want to clean driveways, fences, or large surfaces
- You need long continuous runtime without swapping batteries
- You expect heavy-duty, abuse-proof construction
The verdict
The Sun Joe 24V Cordless Pressure Washer is the right tool for a specific job: portable, battery-powered rinsing of gear and furniture. Its low flow makes it wrong for big surfaces, and the plastic wand wears fast, but for off-grid cleaning with a shared 24V battery it delivers. As a budget cordless pick, it does exactly what I needed.

Sun Joe 24V Cordless Electric Pressure Washer FAQs
Yes for rinse and soap work, with a caveat. At 770 PSI and 0.5 GPM it will not match a corded electric for cutting through hardened bug guts, but it is plenty for a soap dwell and rinse. Plan on roughly 18 to 22 minutes per car including a battery swap.
Specs indicate about 13 minutes of trigger time on a fresh 4 Ah pack. Real cleaning sessions extend longer because you are not on the trigger continuously. A bike wash took about 6 minutes of trigger time. Two patio chairs took about 4 minutes.
If you have outlets and a hose at the work area, the [SPX3000](/reviews/sun-joe-spx3000-pressure-washer) at 2030 PSI is more useful for general cleaning. If your work happens away from outlets (a campsite rig, a dog grooming setup, a beach kayak rinse), the 24V cordless is the only one that solves your problem.
Yes. The included intake hose drops into a 5 gallon bucket. We compared it with a clean bucket of water and the pump primed and held flow without issue. Bucket draw makes the unit usable in driveways with no spigot or in remote campsite work.
