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.
