ST-4 Wave four-gallon floor-machine shampoo tank

Mytee ST-4 is a graduated translucent four-gallon roto-molded polyethylene shampoo tank with a large fill port, faucet-fill hose, rear drain, quick-release clamp, tethered lid, and stainless-steel and brass fittings. The manufacturer explicitly names PowerGlide and UltraGlide and describes a broader design for most floor machines, but does not establish universal mounting or chemical compatibility. Confirm the exact machine, tank and clamp geometry, hose and fittings, chemical compatibility, fill and drain routing, weight, leak control, and current instructions before ordering or installation.
