Why electric start on a soft wash unit?

Because a house-wash day is twenty starts and a pull-start wears out the crew first. Electric start removes the fatigue from the day for a modest price on top of a proven roof-and-house pump.

Can I mix on the fly?

Yes — add a proportioner to meter chemical into the stream at a set ratio instead of batching into a tank. We carry the one built for the AR45 and the P40 and can set you up with the right one and the soft wash hose to match. When it stops drawing, treat it as an injector fault — the soap-injector guide is the quick diagnostic.

How do I tip the AR45 for house wash?

Soft wash needs a lower pressure setting than a pressure job — it is concentration and dwell doing the cleaning, not impact. The nozzle sizing post and the PSI vs. GPM guide explain the low-pressure side of the trade-off so you are not overshooting the roof.

What it's for

The AR45 with electric start, which matters more than it sounds like it should when you are starting the unit twenty times a day. A pull-start is fine on the first job and tiresome by the fourth.

A proven soft wash pump for house washing and roof work. Add a proportioner if you want to mix on the fly instead of batching in a tank.

What we see on the bench

Electric start is a real spec on a soft wash unitYou start the unit dozens of times a day on house washes. Electric start matters more than it sounds — a pull-start is fine on job one and tiring by job four. The AR45 is a proven soft wash pump for house and roof work.
Proportioner vs. batch mixingThe AR45 takes a proportioner that sits on the low-pressure side. It turns batching five gallons into metering what you need. See the proportioner built for the AR45 and P40.
Keep an eye on the injector circuitA stuck-open injector bleeds pressure the whole time you work and nothing looks wrong. The won’t-build-pressure check and the injector bypass kit are the fast way to rule it in or out.
