21V cordless · 300–1000 PSI · no hose needed
Real pressure. No hose. No outlet.
300 to 1000 PSI from a 21V pack, pulling water out of a bucket, barrel or pool up to 4 m below you. Six spray modes, a foam pot, and a washer that weighs 2.9 lbs with the battery in.
Battery, charger and case included
No hose, no outlet
Lifts water from a bucket, barrel or pool up to 4 m below you. The 200-inch hose and inline filter are in the box.
6-in-1 nozzle head
Stains, floor, car, windows, shower and foam. Twist the head — no tools, no swapping tips.
21V · 4000 mAh
20 to 30 minutes of run time per charge, back to full in 3 to 4 hours on the included base.
2.9 lbs, one hand
Washer and battery together, with 300 to 1000 PSI and a 13 ft spray range behind them.
Built for the jobs you keep putting off
One tool. Every mess it handles daily.
Pressure where you need it, gentleness where you don't — all from water you already have on hand.
Car care
Your car, without the trip to the car wash
Jet mode puts up to 1000 PSI on wheels, arches and door sills, so road film and brake dust lift instead of smearing. Screw on the foam pot for a soap layer, swap back, rinse it off.
- Up to 1000 PSI on wheels, arches and sills
- Foam pot lays down soap, jet lance rinses it off
- Around 13 ft of reach, so you stay put while you work
One head, six jobs
Twist the nozzle, change the job
Every mode lives on the same head, so you are not hunting for a tip in a drawer. Turn it a click and the spray pattern changes under your hand.
- Stains, floor, car and window modes
- Shower mode for plants, paintwork and pets
- Foam mode on the same head, no adapter
Jet or foam
A long jet lance and a foam pot, both in the box
The lance narrows the stream for stubborn dirt at range. The foam pot screws straight on for an even soap coat. Neither one is an upsell — both ship with the washer.
- Long lance concentrates the jet on baked-on dirt
- Foam pot spreads soap evenly instead of in patches
- Swap between them in a couple of seconds
Draw water from anywhere
A bucket, a barrel, a pool — it doesn't care
Drop the filtered intake into whatever water you have. It lifts from up to 4 m below the unit, which covers a bucket at your feet or a pool a floor down.
- 4 m suction height, so the source can sit well below you
- 200-inch hose and inline filter included
- 3.4 L/min, so a 5-gallon bucket goes a long way
Power
21V, 4000 mAh, and a base that keeps it full
Ten cells behind a 220 W motor. Enough for a full car wash or a run of smaller jobs, and it charges back up while it sits on the base.
- 20 to 30 minutes of run time per charge
- Back to full in 3 to 4 hours
- Single-port charging base and adapter included
What you actually get
Nine pieces in a hard case, nothing to buy after
21V 4.0 Ah battery, charging base and adapter, 6-in-1 nozzle, long jet lance, foam pot, 200-inch hose, hose connect adapter, inline water filter, and the case they all live in.
Three steps, start to clean
Drop the intake in your water
Bucket, barrel, jerry can or pool — the filtered intake lifts from up to 4 m below the unit, down the 200-inch hose.
Twist to the mode you need
Stains and floor for hard dirt, car and window for panels and glass, shower for plants, foam for soap.
Squeeze, clean, dock
Pull the trigger and work the mess off. Set it back on the charging base and it is full again in 3 to 4 hours.

Questions
Everything people ask before buying
Still unsure? Message us and a real person answers, usually the same day.
Correct. It runs on a 21V 4000 mAh battery and pulls its own water through the 200-inch hose and inline filter — from a bucket, barrel, jerry can or pool sitting up to 4 m below the unit.
300 to 1000 PSI (2.07 to 6.9 MPa) at 3.4 L/min, from a 220 W motor. That is washing pressure — plenty for wheels, panels, patios and steps, but not a substitute for a 2000 PSI corded machine on a concrete driveway.
20 to 30 minutes of trigger time, which is roughly one car or a run of smaller jobs. The included single-port base brings it back to full in 3 to 4 hours.
Nine pieces: the washer, a 21V 4.0 Ah battery, the charging base and adapter, the 6-in-1 nozzle head, a long jet lance, a foam pot, a 200-inch hose, a hose connect adapter and an inline water filter — all in a hard storage case.
Stains, floor, car, windows, shower and foam. They all live on one nozzle head, so you twist between them rather than swapping tips.
Yes — shower mode is gentle enough for beds, pots and hanging baskets. Keep the stain and floor modes away from anything delicate.
2.9 lbs with the battery in, and the spray carries around 160 inches (about 13 ft), so you can stand back from what you are cleaning.
It works anywhere you can catch or drain the water. Garages, balconies and yards with no outdoor tap are the main reason people buy it.
