A pressure washer you can carry with one hand.
HydroBlast HB-1 is a cordless handheld pressure washer for driveways, decks, vehicles, and the jobs around the house that don’t need a gas-powered machine. Light enough to carry, simple enough to keep in a closet.
Four steps. No instructions to memorize.
No app, no subscription, no proprietary refills. Connect water, pick a nozzle, choose a mode, pull the trigger.
Built for residential outdoor cleaning. For heavy commercial work like paint stripping, a corded electric or gas washer is the right tool.
- 01Connect a water source
Garden hose via the 3/4 in. quick-connect, or drop the 20-ft. self-priming intake into a bucket.
- 02Pick a nozzle
Fan-spray for the everyday, pinpoint-jet for stuck-on grime, rotary brush for vehicles, foam-soap for pre-soak.
- 03Choose a mode
Eco for delicate surfaces, Standard for most jobs, Max for the toughest concrete and stone.
- 04Pull the trigger
Up to 870 PSI at the nozzle. The brushless motor only runs while the trigger is held.
One trigger. Three settings. No guesswork.
Tap the side button to switch between Eco, Standard, and Max. The trade-off between pressure and runtime is published below — and nowhere are we going to add a story to it.
Lowest output, longest runtime per charge. Best for vehicles, painted surfaces, outdoor furniture, and anywhere you want to be gentle.
Balanced pressure and flow. The mode most owners leave it in — siding, decks, patios, bikes, grills, planters.
Top pressure for caked-on grime — concrete driveways, paving stones, and the bottom of trash bins. Shorter runtime per charge in exchange.
Designed to outlive the cleaning job.
A brushless motor, a glass-reinforced housing, and a battery you can replace through the warranty if it ever wears out. Made to be a long-term piece of household kit.
- Brushless DC motor
- Quieter, more efficient, and longer-lived than a brushed motor — no carbon dust to wear out the windings.
- 3.0 lb in your hand
- With battery installed. Light enough that you can finish a driveway without putting it down.
- USB-C charging
- Standard USB-C, 30 W. No proprietary brick to lose — any compatible charger you already own will do.
- Self-priming pump
- Draws water from a hose, a bucket, a rain barrel, or any open freshwater source within 10 seconds.
- Glass-reinforced ABS
- Tough housing with a TPE-overmold grip. IPX4 splash-resistant — survives the inevitable spray-back.
- Four-nozzle kit, included
- Fan-spray, pinpoint-jet, rotary brush, and foam-soap reservoir. Nothing locked behind an upsell.

“We didn’t want to sell another ‘10,000 PSI’ gimmick washer. We wanted to make a small, honest tool — the one that fits in a closet, handles the actual jobs you have, and tells you what it is on the side of the box.”

Quick answers.
If you don't see your question here, our support team is in the United States and we answer real email in real hours.
Does HydroBlast HB-1 connect to a regular garden hose?
Yes. A 3/4-inch quick-connect adapter is included. You can also use the 20-ft. intake hose to draw water from a bucket, rain barrel, or other freshwater source.
How long does the battery last on one charge?
Up to 40 minutes of continuous use in Eco mode. Max mode reduces runtime in exchange for higher pressure. A full recharge takes approximately 70 minutes over USB-C.
What surfaces is it safe to use on?
Driveways, patios, decks, siding, outdoor furniture, vehicles, bikes, grills, planters, pool decks, and similar exterior surfaces. We recommend testing a small area first on painted, treated, or delicate finishes.
How does the warranty work?
Every HydroBlast HB-1 is covered by a 1-year limited warranty against manufacturing defects. Registration is optional — your order receipt is your proof of purchase. See the warranty page for full terms.
Monday – Friday, 9:00 AM – 5:00 PM ET. Average response time is under one business day.
