Active 3.0 Electric Pressure Washer

SE24AU(02)

Bundle: Tool Only
In-stock: Inventory updated

11.4 L/min flow. 1,000 psi working pressure. Low-speed induction motor. Patented 5-piston serviceable pump. The ACTIVE 3.0 is the flagship of the Active range, built on the idea that flow matters more than pressure. More water moving over the panel rinses faster, carries foam better and lifts dirt with less force, which is what you want on paintwork.

Best ACTIVE for detailers who want maximum flow and a pump they can service, in a machine quiet enough to run in a residential driveway.

Why flow11.4 litres a minute is high for an electric machine. More water means faster rinsing, thicker foam through a cannon, and dirt lifted by volume rather than by force, which is gentler on paint.
Induction motorLow-speed induction rather than a universal motor. It runs quieter at around 75 dB, generates less heat and lasts longer under sustained use. Universal motors are cheaper and louder.
Serviceable pumpOil-filled with fill and drain ports, so the pump is maintained rather than replaced. Upgraded seals, valves and pistons over the 2.0 and 2.3.
PowerRequires a 15 amp outlet. This uses a physically larger plug than a standard 10 amp point, so confirm your supply before ordering.
ServicingFirst oil change at 25 hours, then every 100 hours. The fill and drain ports make it a five minute job.

Best suited to

Ideal for

  • Detailers who foam and rinse every car and want speed
  • Anyone running a premium foam cannon that needs flow to work properly
  • Residential driveways and shared spaces where noise matters
  • Owners who would rather service a pump than replace a machine
  • Stepping up from a 2.0 or 2.3 and wanting the flagship

Not the right choice if

  • You only have a standard 10 amp outlet
  • You want maximum pressure rather than maximum flow
  • You need hot water, this is a cold water machine
  • Your water supply cannot sustain 11.4 L/min, the machine can only move what reaches it

What it can handle

Task Suitability
Pre-wash and rinsing ExcellentThis is what the flow rate buys you. Rinsing is noticeably faster than a lower-flow machine.
Snow foam through a cannon ExcellentFoam cannons need flow to produce thick, clinging foam. A 1.65 mm foam cannon orifice is supplied.
Wheels and arches Excellent
Driveways, patios and hard surfaces Excellent
Daily commercial detailing use ExcellentInduction motor and serviceable pump are what make sustained daily use realistic.
Engine bays SuitableUse a wide fan nozzle and keep your distance from electrical connections.
Heavily caked machinery or concrete Check requirementsThis is a flow machine tuned for vehicles. Heavy industrial cleaning wants more pressure.
Hot water cleaning Not suitableCold water only, maximum inlet temperature 40 degrees.

Suitability above is general guidance based on the machine's published flow and pressure against typical detailing tasks, not a performance guarantee. Results depend on your water supply, nozzle selection, chemical and technique.

Flow versus pressure, and why it matters

Pressure washers are usually sold on pressure, because it is the bigger and more impressive number. For detailing it is the wrong number to lead with.

Pressure is force. It is what strips paint from a fence, and it is also what damages trim, lifts badges and forces water past seals if you get too close to a car.

Flow is volume. It is what carries dirt off the panel and away, what makes foam thick enough to cling and dwell, and what lets you rinse a whole car quickly.

At 11.4 litres a minute the ACTIVE 3.0 sits well above most domestic electric machines, which typically manage 6 to 8. Working pressure is a deliberate 1,000 psi, which is plenty for a car and gentle enough not to risk the finish. That combination is the whole design philosophy.

Why choose the 3.0

11.4 L/min

The highest flow in the ACTIVE range, and high for any electric machine. Faster rinsing, better foam, less time per car.

Low-speed induction motor

Quieter at around 75 dB, cooler running and longer lasting than the universal motors used in cheaper machines. It is the single biggest difference between a machine that lasts and one that does not.

Patented 5-piston pump

Five pistons deliver smoother, more consistent flow than a three-piston pump. Oil-filled with dedicated fill and drain ports, so you service it rather than replace the machine.

Upgraded internals

Seals, valves and pistons use better materials and treatments than the 2.0 and 2.3, specifically for longer running life.

Foam cannon ready

Ships with a 1.65 mm foam cannon orifice, so aftermarket cannons work properly straight away rather than starving for flow.

M22 outlet

Standard M22 connection, so hoses, guns, lances and cannons from the wider detailing market fit without adaptors.

Installation and setup

  • Requires a 15 amp outlet. This uses a physically larger plug than a standard 10 amp point, and if you do not have one a licensed electrician will need to install the circuit.
  • Do not run it through a 10 amp extension lead or adaptor.
  • Check your water supply can sustain the machine. ACTIVE specify at least 40 psi inlet pressure and more than 3 GPM flow. A restricted tap or a narrow hose will starve the pump no matter what the machine is rated for.
  • The inlet is a North American 3/4 inch 11.5 TPI thread, so check you have the right adaptor for your tap.
  • Use a steel-braided hose with at least 5/16 inch internal diameter. A thin hose is the most common cause of a high-flow machine underperforming.
  • Never run the pump dry. Turn the water on before the machine, and off after it.

Maintenance

The serviceable pump is one of the main reasons to buy this machine over a sealed-unit alternative, but it only helps if you use it.

Interval Task
First 25 hours Change the pump oil. This first change clears any particles from bedding in.
Every 100 hours after that Change the pump oil.
Before each use Check the inlet filter is clean. Grit reaching the pump is what kills valves and seals.
After each use Release trigger pressure and disconnect. If storing somewhere cold, drain the pump.

Running it from a generator

ACTIVE publish generator requirements for their pressure washers: 1,800 watts running and 3,000 watts surge. Every Westinghouse generator we stock clears that comfortably, including the smallest.

They also specify the water supply: at least 40 psi inlet pressure and more than 3 GPM flow. That matters more than most people expect, since a restricted tap will starve the pump regardless of what the machine is rated for.

For mobile work, see our Westinghouse generator range. The iGen4750PRO delivers 3,800 running watts and 4,750 starting, so it runs this machine with headroom to spare.

Choosing the right ACTIVE

Choose the 3.0 if you want the highest flow in the range, an induction motor and a pump you can service. It is the flagship and it is priced accordingly.
Step down if you are a weekend detailer or working from a 10 amp outlet. The ACTIVE 2.0 delivers 7.7 L/min at 1,100 psi and runs on a standard point, which covers most home use comfortably.
The middle option is the ACTIVE 2.3, more output than the 2.0 without stepping up to the flagship. See the full ACTIVE range.
You will also want the ACTIVE Premium Foam Cannon to make use of the flow, and a proper steel-braided hose. A thin hose throttles a high-flow machine.

Common questions

Can I plug it into a normal power point?

No. The Australian and New Zealand version uses a 15 amp plug, which is physically larger than a standard 10 amp point and will not fit one. Do not use a 10 amp adaptor or extension lead to get around it. If you do not have a 15 amp outlet, an electrician will need to install one, or look at the ACTIVE 2.0 which runs on a standard point.

Why is flow more important than pressure for car washing?

Pressure is force and flow is volume. Force is what damages trim and forces water past seals. Volume is what carries dirt off the panel and away. For paintwork you want plenty of water moving at moderate pressure, which is exactly how ACTIVE tune their machines. It is also why a high-flow machine makes noticeably better foam.

What is the difference between an induction and a universal motor?

Universal motors are small, light, cheap and spin very fast, which makes them loud and hot. They are what most domestic pressure washers use. Induction motors run slower and cooler, are quieter, and last considerably longer under sustained use. They also cost more and weigh more, which is why you find them on professional machines.

Will it work with my foam cannon?

Yes, and it will work better than on a lower-flow machine, because foam cannons need volume to produce thick clinging foam. A 1.65 mm foam cannon orifice is supplied for use with aftermarket cannons. The outlet is standard M22 so most guns, lances and cannons fit directly.

What maintenance does it need?

Change the pump oil after the first 25 hours, then every 100 hours. The pump has dedicated fill and drain ports so it is a straightforward job. Also keep the inlet filter clean, since grit reaching the pump is what destroys valves and seals, and never run the pump dry.

Does my tap need to keep up?

Yes, and this catches people out. A pump can only move the water that reaches it. If your tap or hose cannot sustain 11.4 L/min the machine will cavitate and underperform, which people often mistake for a faulty unit. Use a good quality hose with at least 5/16 inch internal diameter, and check your tap flow before blaming the machine.

Can I use hot water?

Not beyond 40 degrees at the inlet. This is a cold water machine. Feeding it hot water will damage the pump seals.
