    Introducing the commercial tray washer from Bootstrap Farmer - the solution farmers have been seeking for growing at scale. Crafted with precision in the USA, this rock-solid and uncomplicated unit is designed for microgreens growers who harvest 100 trays or more per week. 

    Stop wasting time on tedious hand scrubbing and embrace convenience — without compromising on impeccable food safety, sanitization, and cleanliness.


    Bootstrap Farmer’s Texas-fabricated, stainless steel tray washer speeds up tray washing with four powerful high-pressure fan nozzles and a low-pressure sanitizing rinse. The tray washer requires a pressure washer (purchased separately) to function. See pressure washer recommendations below. 

    Trays are manually pushed upside down along a rail system that holds them in place during the wash cycle. Water is contained via brushes that help keep the overspray to a minimum. Self-draining feed ramps help divert excess water back inside the unit to drain to waste. Upon exit, the trays fall onto a collection ramp that channels excess water back into the unit to drain. After use, unit cleaning is quick by removing the secured lid and rinsing it out. 


    • The unit is fabricated in Texas out of stainless steel and is powered by a pressure washer (purchased separately). 
    • All-steel, compact, solid-unit with brushes to contain overspray. 
    • Four high-pressure nozzles and a low-pressure rinse. Pressure washer and hoses not included.

    You will need to supply a pressure washer with a minimum of 10,500  Cleaning Units (CU). To compute CU, multiply the PSI x GPM ratings of the pressure washer unit. See our recommendations below.

    Recommended pressure washers to operate the tray washer:

    Landa PE4-30024A Industrial Cold Water Pressure Washer - 3.5 GPM, 3000 PSI (10,500 Cleaning Units)

    Landa HD 3.5/35 Industrial Cold Water Pressure Washer - 3.5 GPM, 3500 PSI (12,250 Cleaning Units)

    • If washing indoors, we recommend waterproofing walls, draining into a floor drain or sink, and using an electric pressure washer like the ones listed above.
