⚡ Quick Answer
At the top of the commercial‑grade lineup sits the Attachxpro Gas Pressure Washer, listed at $3,199.00. With a 13.5 hp engine, 4,000 psi pressure and a 4.0 gpm flow rate, it pairs a steel frame and triplex pump with hot‑water capability that cuts through grease faster than cold‑water units. Its 75‑ft hose and electric start make it a mobile workhorse for contractors who need power on the go.
The remaining three models cover both budget and premium corners. The Steupoek, priced at $399.99, delivers 4,200 psi at 4.0 gpm, a 7 hp 4‑stroke engine and a 32‑ft hose, all on a 77‑lb steel frame with a never‑flat wheel. IvyBess, at $385.00, matches the same pressure and flow but comes on a lighter 66‑lb chassis and a shorter 25‑ft hose. At the high end, Easy Kleen tops out at $4,325.00, offering 4,000 psi, 3.5 gpm, a 13 hp engine and a massive 10‑gal fuel tank, but it weighs 443 lb.
Next we’ll break down each unit’s power output, portability, and feature set so you can see which machine aligns with your cleaning demands and budget.

Attachxpro Gas Pressure Washer
Its 4.0 GPM flow rate delivers strong cleaning power for the price.

Steupoek Gas Pressure Washer
Ideal for entry‑level buyers, it costs $399.99—about $2,799 cheaper than the Attachxpro.

IvyBess Gas Pressure Washer
Weighing just 66 lb, the IvyBess offers a compact, lightweight option not found in the higher‑priced models.
TL;DR: The Steupoek 4200 PSI Gas Pressure Washer packs a 7 HP engine, 32‑ft hose and five quick‑connect nozzles into a steel‑frame unit that’s powerful enough for big jobs while staying under $400.
What really stands out is the 7 HP, 212 cc 4‑stroke OHV engine paired with an axial cam pump, delivering a maximum of 4200 PSI at 4.0 GPM. That pressure level lets you blast away stubborn grime on driveways, decks or vehicles without needing a commercial‑grade machine.
Compared with the IvyBess model, the Steupoek’s 32‑ft steel‑braided hose gives you seven extra feet of reach, and its steel frame with never‑flat wheels adds durability that the IvyBess’s pneumatic wheels don’t match. It’s heavier than the IvyBess’s 66 lb unit, but far lighter than the Easy Kleen’s 443 lb behemoth. The Attachxpro sits in a different league with a much larger chassis and longer hose, but its premium price reflects that scale.
Professional reviewers note the robust 7 HP engine and aluminum axial cam pump as key durability factors, while everyday users appreciate the five interchangeable nozzles—including a dedicated soap tip—and the 1 L built‑in detergent tank. The recoil start is straightforward, though it does require a manual pull each time you fire up the machine.
Pros
Cons
Best for: Homeowners or semi‑professionals who need commercial‑level pressure without the premium price tag – the Steupoek offers five nozzles and solid build quality.
Avoid if: You need the most advanced features, ultra‑lightweight design, or a machine built for continuous professional use.
TL;DR: The IvyBess Gas Pressure Washer delivers 4200 PSI at 4.0 GPM, packs five quick‑connect nozzles and a 1‑L soap tank, and weighs 66 lb, making it a solid entry‑level option for heavy‑duty cleaning.
What really stands out is the 4200 PSI maximum pressure combined with a 4.0 GPM flow rate. That pressure level can blast away stubborn grime on driveways, decks, and vehicles, while the flow rate keeps the job moving quickly. The unit is powered by a 212 CC, 7.0 HP 4‑stroke gasoline engine and uses a maintenance‑free axial cam pump, which the manufacturer says helps keep upkeep costs low.
Compared with the other three washers in this roundup, IvyBess is lighter at 66 lb versus Steupoek’s 77 lb, but far lighter than Easy Kleen’s 443 lb. Its 25‑ft steel‑braided hose is shorter than Steupoek’s 32‑ft hose, the Attachxpro’s 50‑100 ft range, and Easy Kleen’s 50‑ft hose, so you’ll need to move the machine a bit more on larger jobs. All three competitors list five or more nozzles, matching IvyBess’s 5‑count quick‑connect set, while only the Steupoek model matches IvyBess’s 4200 PSI rating. The Attachxpro and Easy Kleen entries don’t list pressure, so IvyBess sits comfortably in the middle of the performance spectrum.
User sentiment notes the strong cleaning power and the convenience of the built‑in 1‑L soap tank, which lets you mix detergents on the fly. Reviewers also appreciate the pneumatic 8‑inch/10‑inch wheels that roll over rough terrain without flattening. On the downside, the product has only 29 reviews and a 4.4‑star average, indicating fewer data points for confidence. Some buyers mention the shorter hose as a limitation when tackling far‑reaching surfaces.
Beyond the raw numbers, the washer meets EPA, CARB, and ETL certifications, and its steel frame adds durability for outdoor use. The recoil start system means you won’t need a battery, and the chemical injection feature lets you add cleaning agents directly into the water stream. Overall, IvyBess balances commercial‑grade power with a price that fits a tighter budget.
Pros
Cons
Best for: Entry-level buyers or those on a tight budget — the IvyBess Gas Pressure Washer offers Nozzle Count: 5
Avoid if: Reliability and user satisfaction are your top concerns
TL;DR: The Attachxpro delivers commercial‑grade 4000 PSI pressure, 4.0 GPM flow and 200 °F hot water with a 13.5 HP diesel engine, but its $3199 price and 400 lb weight suit professionals more than casual users.
What sets this unit apart is its combination of 4000 PSI pressure and a 4.0 GPM flow rate, powered by a 13.5 HP, 420 cc overhead‑valve gas engine. The integrated diesel‑fired burner produces 330,000 BTU of heat, raising water up to 200 °F for aggressive grease and oil removal. A 75‑ft, 3/8‑inch hose gives you reach across large job sites, while the five‑piece nozzle set adds flexibility for everything from delicate rinses to heavy‑duty stripping.
Compared with the three other washers in this roundup, the Attachxpro is heavier than the Steupoek and IvyBess units (those weigh 77 lb and 66 lb) but lighter than the Easy Kleen’s 443 lb frame. Its 75‑ft hose outstrips Easy Kleen’s 50‑ft, Steupoek’s 32‑ft and IvyBess’s 25‑ft hoses, giving it the longest reach. Pressure is a touch lower than the 4200 PSI offered by Steupoek and IvyBess, while flow matches their 4.0 GPM rating. The machine’s overall footprint (35 × 44 × 42 in) is larger than the compact 20 × 22 × 20 in dimensions of the lighter models, reflecting its industrial‑grade construction.
Professional reviewers highlight the hot‑water capability as a major time‑saver, noting that the 330,000 BTU burner dissolves stubborn industrial grease faster than cold‑water units. The roll‑cage steel frame and flat‑free 13‑inch tires earn praise for stability on rough terrain, and the electric start is lauded for quick ignition. However, users note that maintaining both the gasoline engine and diesel burner adds complexity, and the 400 lb weight often requires a crane or forklift for relocation, making it less suited for occasional DIY projects.
Additional technical details reinforce its commercial focus: a 55 AH battery supports auxiliary functions, a 20 % chemical injector boosts detergent efficiency, and a 5‑8 gal diesel tank ensures long runtimes. Thermal protection features—including a relief valve and high‑limit over‑temp safeguard—help prevent overheating during extended use. The powder‑coated steel frame, pneumatic flat‑free tires and 4‑wheel roll‑cage design round out a rugged package built for demanding environments.
Pros
Cons
Best for: Professional cleaners, contractors and industrial users who need hot‑water power and robust durability – the Attachxpro offers Flow Rate: 4.0 GPM.
Avoid if: You are a casual homeowner, lack the means to handle dual‑fuel logistics, or cannot accommodate the heavy, forklift‑sized equipment.
TL;DR: The Easy Kleen Hot Water Pressure Washer delivers 4000 psi at 3.5 gpm with a 13 hp Honda engine, but its $4325 price and 443‑lb weight make it a premium, heavy‑duty choice.
The standout spec is its 4000 psi maximum pressure paired with a flow rate of 3.5 gpm, driven by a 13 hp Honda engine and a 350,000 BTU oil‑fired burner. A fully welded steel frame, pneumatic 13‑inch tires, and an electric start round out a commercial‑grade package.
Compared with the other three units in this roundup, the Easy Kleen sits at a higher price point than the Attachxpro Gas Pressure Washer and is considerably heavier than the sub‑100‑lb Steupoek and IvyBess models. Its overall dimensions of 30 × 48 × 46 inches also outsize the more compact competitors, which can matter for storage and transport.
User feedback highlights the robust construction and the convenience of downstream chemical injection, noting that the five‑nozzle setup (four wash nozzles plus one soap nozzle) tackles a range of cleaning tasks. The same reviews point out that the 443‑lb weight and large footprint make the unit a challenge to move and store in tighter spaces.
The washer includes a 50‑ft high‑pressure hose and a 10‑gal fuel tank, giving you long run times without frequent refueling. An electric start simplifies ignition, while the pneumatic tires help maneuver the heavy frame across job sites.
