The HOTO 20V Pressure Washer Pro is a portable, battery-operated cleaning device. This manual provides instructions for assembly, operation, and maintenance. Always ensure the battery is charged and the water inlet filter is clean before use. The device supports both self-priming (from a bucket) and faucet water supply.
Product Overview
The device consists of the following main components:
- Multi-Function Nozzle
- Spray Lance
- Soap Holder
- Handle
- Trigger
- Battery Pack
- Water Inlet Filter
Assembly and Disassembly
Spray Lance: Align the reducer of the spray lance with the slot inside the handle. Rotate the gun 90 degrees in the arrow direction to lock it. To disassemble, press and push the spray lance backward, then rotate 90 degrees and draw it out.
Soap Holder: Align the soap holder with the slot in the spray lance and rotate about 45 degrees to lock. Reverse the process to disassemble.
Battery Pack: Align the "●" mark on the handle with the "●" mark on the battery pack. Rotate 90 degrees until it locks. To remove, rotate 90 degrees in the opposite direction and pull downward.
Operating Instructions
Water Modes: Rotate the shell of the multifunctional nozzle to align the arrow with the desired mark. Five water types are available:
- Jet mode: For rinsing stubborn stains.
- 20-degree/40-degree water mode: For routine cleaning (cars, bicycles, windows).
- Foam/Shower mode: For spraying foam (with soap) or showering (without soap).
- Tilted mode: For cleaning higher planes like the top of a car.
Battery Charging: Remove the waterproof cover on the battery pack. Connect the USB-C charger to the battery pack. The battery level can be checked by pressing the display button.
Care and Maintenance
Cleaning the Water Inlet Filter: Rotate the water inlet filter head to remove the lower part, take out the filter, clean it, and reassemble.
Storage: Drain the machine and water pipe before storage. Wipe the body with a soft cloth. Keep in a safe, dry place away from frost and children.
Troubleshooting
If the washer does not start, check if the battery is properly installed or depleted. If the self-priming function fails, ensure the washer is not higher than 1.5m above the water surface, check for hose leaks, and ensure the inlet filter is clean and submerged.
