CM-3600-0MMB Gas Pressure Washer — 3600 PSI ChoreMaster with AR Crankshaft Pump
The Mi-T-M ChoreMaster CM-3600-0MMB steps up from the CM-3000 with a 300cc Mi-T-M OHV engine, an AR crankshaft pump, and 3,600 PSI at 2.8 GPM — 10,080 cleaning units. The crankshaft pump design handles longer continuous-duty cycles better than an axial pump, making this model the right choice when the machine runs several hours per day rather than occasional use. Includes a 50-foot wire-braided hose instead of the 25-foot hose on the CM-3000 — a meaningful difference on larger surfaces.
CM-3600-0MMB Cleaning Output and Pump Comparison
The jump from axial to crankshaft pump design is the key upgrade at this tier — crankshaft pumps run cooler and last longer under sustained load, which matters for crews cleaning multiple properties per day.
-
3,600 PSI at 2.8 GPM (10,080 CU) — 40% more cleaning units than the CM-3000; handles concrete stripping and heavy equipment washing where the 3,000 PSI unit works slowly
-
300cc Mi-T-M OHV engine — larger displacement means more torque headroom; engine doesn't bog under load on thick grime or surface cleaners
-
AR crankshaft pump — triplex piston design with forged brass manifold; rated for higher duty cycles than axial pumps at the same pressure rating
-
Adjustable pressure unloader — dial pressure down for delicate surfaces (vehicles, painted wood) without swapping nozzles
-
50-foot wire-braided hose — covers a full parking stall row without repositioning the machine; eliminates a second trip around large equipment
-
Thermal relief valve and in-line water strainer — pump protection standard on all Mi-T-M commercial models
CM-3600-0MMB Applications and Environments
Contractors maintaining commercial parking lots, warehouses, and agricultural facilities will find the CM-3600-0MMB handles sustained multi-hour cleaning sessions that would overheat an axial-pump unit. Farm equipment cleaning — tractors, combine headers, livestock trailers — benefits from the extra PSI and GPM for cutting through caked soil and manure. Property restoration companies use it for post-construction cleanup on concrete foundations and masonry. The 130 lb weight is heavier than the CM-3000 but still manageable for a two-person crew loading onto a job trailer.
