THE SHORT ANSWER

Our take

A well-documented gas option for professional users who can work within its 25-foot hose reach, 74-pound frame, and 49-state market restriction.

Consider it for

A documented contractor-oriented gas model for buyers who want a GX200, the AAA AX300 axial-cam pump, and a 25-foot hose..

Look elsewhere if

A California buyer, someone who needs corded-electric operation, or a user who requires a 50-foot hose should look at other documented models.

Pros & cons

What could work for you, and what to consider before buying.

What works in its favor

  • SIMPSON lists the Honda GX200, AAA AX300 axial-cam pump, and a 3500 PSI at 2.5 GPM output.
  • The 25-foot MorFlex hose, five quick-connect nozzle tips, and 10-inch pneumatic tires are documented for this model.
  • The manufacturer publishes dimensions and a 74-pound weight, which helps with vehicle and storage planning.

What to weigh up

  • The 25-foot hose is shorter than the 50-foot hose documented for the PS3835.
  • The gasoline engine and 74-pound unit require fuel, outdoor operating space, and a transport plan.
  • The current PS61002-S variant is not for sale in California, and the historical ASIN is not confirmed against the current variant.

Full review: how the features affect your choice

What the features mean for you

Pressure and flow

SIMPSON's current model material lists the PS61002-S at 3500 PSI and 2.5 GPM. Those are model specifications, not results from our own cleaning test, and the page describes pressure and flow as ratings. Use them to set requirements alongside nozzle choice and the surface being cleaned. A contractor who mainly wants a 25-foot hose and this pressure-and-flow class can compare it directly with other documented gas units, but should not infer a guaranteed area-per-hour rate from PSI or GPM alone. The source row's ASIN does not identify the current offer, so this review applies to the manufacturer-described PS61002-S variant and uses an exact-model Amazon search link.

Engine and pump

The manufacturer pairs this version with a Honda GX200 engine that has low-oil shutdown and an AAA AX300 axial-cam pump. That pairing is a concrete differentiator from the larger PS3835, which uses a GX270 and an AAA industrial triplex pump. Gas operation brings its own setup: fuel, oil checks, engine maintenance, outdoor exhaust clearance, and a stable operating location. The product page positions the PowerShot line for contractors and other professional cleaning work. These are documented parts and positioning statements, not a claim that every buyer needs a professional washer or that the model is free of maintenance. Read the supplied manual for starting, fuel, oil, water, and safe-use instructions.

Hose reach and included tips

SIMPSON lists a 5/16-inch by 25-foot MorFlex high-pressure hose with M22 fittings and five quick-connect nozzle tips: 0°, 15°, 25°, 40°, and soap. That gives a buyer specific connection and reach details to check against a work layout and existing equipment. The 25-foot hose may require moving the frame more often than the PS3835's documented 50-foot hose, but the product sources do not measure repositioning time. Confirm whether the current seller's box includes the listed pieces and whether a particular accessory matches the machine. The historical ASIN B07TW9X28H has not been tied to this exact current model variant, so this page does not link to that ASIN directly.

Moving and storage

The manufacturer lists 10-inch premium pneumatic tires, a welded steel frame, dimensions of 21 by 24 by 34 inches, and a unit weight of 74 pounds. Those details make this a substantial wheeled machine rather than a light hand-carried cleaner. Measure the storage opening, turning space, and vehicle loading height before choosing it; the published dimensions do not include a buyer's clearance allowance or prove a fit. Pneumatic tires are documented as a mobility feature, but they do not make the washer weightless or remove the need to secure it during transport. A buyer who prioritizes lower listed weight may prefer the Greenworks electric model, while a buyer who needs a longer hose should compare the PS3835.

Market and work limits

SIMPSON's current manufacturer page and 2026 catalog identify the PS61002-S as a 49-state/EPA-compliant version and say it is not for sale in California. Keep that market note attached to this suffix; do not apply it to every PowerShot model or assume a historical listing reflects the current version. The manufacturer describes the PowerShot line for professional cleaning tasks such as deck work, wood restoration, paint preparation, and graffiti removal. The machine is gas-powered and designed for cold-water cleaning, so plan for fuel handling, outdoor exhaust clearance, and cold-weather storage. If your work site or jurisdiction does not fit those constraints, use the finder to compare a different power source or verify the exact model before purchase.

Before you buy

Can this exact model be bought in California?

SIMPSON's current PS61002-S page and 2026 catalog say this 49-state version is not for sale in California. Check the exact suffix and applicable local requirements.

How long is the high-pressure hose?

SIMPSON documents a 25-foot, 5/16-inch MorFlex hose with M22 fittings for the PS61002-S.

Does the historical Amazon ASIN prove the current variant?

No. The source row's ASIN has not been mapped to the current PS61002-S variant, so the purchase link searches for the model rather than opening that ASIN.

Where can I check the current price?

Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
