Have questions about this product? Our detailing experts are here to help.
Description
The MAXFLOW DDM is the highest-flow machine in the MAXFLOW line — 3.3 GPM at 1500 PSI, which is where the real-world speed comes from. Flow rinses; pressure only cuts. At 21.6 lbs and 13.2" wide it still fits under a bench or behind a seat, and the 15A/20A power mode selector lets you run it off a normal outlet or unlock full output on a dedicated 20A circuit. Rated for 800 hours — nearly triple the MPro platform.
The DDM is supplied with a NEMA 5-20P GFCI plug. It operates in 15A mode by default. Full 20A performance requires direct connection to a properly installed 20A receptacle and intentional activation of 20A mode. Never operate 20A mode through an adapter.

Pro Detailer Tips
Patch Test First
Before applying any new product to a full panel, test on a small hidden area first — especially on older paint, vinyl wraps, or exotic finishes.
Read the SDS Sheet
Every professional detailing product has a Safety Data Sheet (SDS). Review it before first use to understand proper handling, dilution limits, and safety precautions.
Store Properly
Keep products in a cool, dry location away from direct sunlight and freezing temperatures. Extreme heat or cold can degrade chemistry and shorten shelf life.
