CM-3200-0MMB Gas Direct Drive Pressure Washer — 3200 PSI Crankshaft Pump for Job Site and Property Cleaning
The Mi-T-M ChoreMaster CM-3200-0MMB is a direct-drive gasoline pressure washer built around Mi-T-M's own crankshaft pump rather than the axial-cam pumps found on lower-cost units at this pressure rating. Crankshaft pumps run cooler, handle longer duty cycles, and last significantly longer before requiring service — a meaningful difference for contractors and property owners running the machine for hours at a time rather than occasional weekend use. At 3200 PSI and 2.4 GPM, it produces 7,680 cleaning units — enough pressure and flow for concrete driveways, equipment surfaces, and building exteriors.
CM-3200-0MMB GPM, PSI, and Nozzle Configuration
Cleaning units (PSI × GPM) measure total cleaning productivity — GPM determines how fast you rinse, PSI determines how effectively you break surface bonds.
3200 PSI at 2.4 GPM — 7,680 cleaning units — sufficient for concrete surface cleaning, equipment degreasing, and building exterior wash-down; above the 6,000 CU threshold where concrete cleaning becomes practical
Mi-T-M crankshaft pump with Pressure Relief Start system — crankshaft design outlasts axial-cam pumps for high-duty-cycle applications; Pressure Relief Start reduces engine load at startup, extending motor life
212cc Mi-T-M OHV engine — overhead valve design runs cooler and more efficiently than side-valve engines; consistent power output across extended operating periods
Thermal relief valve and in-line water strainer — thermal relief prevents pump damage if trigger is released and machine runs in bypass mode; water strainer protects pump from sediment in supply water
Built-in low-pressure detergent injector — applies soap at low pressure through the included detergent nozzle without a separate downstream injector or chemical pump
10" flat-free tires on powder-coated steel frame — flat-free tires eliminate tire maintenance on job sites; powder coat protects the frame against rust in wet operating environments
CM-3200-0MMB Applications and Environments
Contractors doing residential exterior cleaning — siding, driveways, patios, and decks — will find the CM-3200-0MMB sized for single-family and small commercial properties where a trailer-mounted hot water unit is overkill. Fleet and equipment maintenance operations at farms, landscaping companies, and small construction firms use it for machine wash-down between jobs, where portability and gasoline independence matter more than flow rate. Vehicle detailing and restoration shops use it for initial rinse and engine bay washing where 3200 PSI provides surface cleaning without the risk of damage from higher-pressure commercial units. Job site cleanup contractors running ground equipment on construction sites find the 10" flat-free tires and 85 lb weight allow single-operator transport across uneven terrain.
CM-3200-0MMB Pump, Nozzle Tips, and Accessories Included
Ships with three quick-connect nozzle tips: 15°, 25°, and detergent (downstream soap). The 25 ft wire-braided high-pressure hose and 36" two-piece lance with trigger gun are included — ready to operate from the box. Cold water only; for hot water or steam cleaning applications, see the Mi-T-M hot water pressure washer line. CARB-compliant engine required for California — consult factory before ordering for CA delivery.

What are the cleaning units (CU) for the CM-3200-0MMB?
The CM-3200-0MMB produces 7,680 cleaning units (3,200 PSI × 2.4 GPM). Cleaning units combine pressure and flow into a single productivity number — 7,680 CU is above the 6,000 CU threshold where concrete surface cleaning becomes practical for typical residential and light commercial applications.
What is the difference between a crankshaft pump and an axial-cam pump?
Crankshaft pumps use a wobble-plate mechanism similar to a car engine — they run cooler, handle longer continuous-duty cycles, and typically last 2–3 times longer than axial-cam pumps before requiring service. Axial-cam pumps are found on lower-cost consumer machines and are fine for occasional use. The CM-3200-0MMB's Mi-T-M crankshaft pump is designed for regular contractor-level use.
What nozzle tips are included with the CM-3200-0MMB?
Three quick-connect nozzle tips are included: 15° (medium-intensity surface cleaning), 25° (general wash-down and rinsing), and a low-pressure detergent tip for soap application. A 0° (zero-degree) tip is not included — for most cleaning tasks, the 15° tip provides adequate pressure concentration without surface damage risk.
Is the CM-3200-0MMB a hot water or cold water pressure washer?
Cold water only. The CM-3200-0MMB does not have a heating element or boiler. For grease, oil, and heavy biological contamination where hot water improves cleaning, see the Mi-T-M hot water pressure washer line or the Fortador steam cleaner range. Cold water at 3200 PSI handles concrete, siding, equipment, and vehicle cleaning effectively.
Can the CM-3200-0MMB be purchased for use in California?
All gasoline-powered models sold in California require a CARB-compliant engine. Consult the Mi-T-M factory before ordering for California delivery to confirm CARB compliance status for the current production run of this model.
What does the Pressure Relief Start system do on the Mi-T-M pump?
The Pressure Relief Start system reduces load on the engine at startup by allowing the pump to start in a low-pressure state before building to full pressure. This reduces the mechanical stress on both the engine and pump during cold starts, extending the life of both components — particularly relevant in cold weather when engine cranking is harder.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
