Usage Features

The HUTT W8 offers several usage features for convenient and effective window cleaning:

Operation Modes:

Dry-wiping: The machine defaults to wet-wiping mode. To dry-wipe, the "Water Spray" function must be turned off using the remote control, and a dry cleaning pad installed.
Wet-wiping: The machine starts in wet-wiping mode directly with a dry cleaning pad installed. It is crucial to use the original cleaning pad to ensure optimal performance.

Installation and Setup:

Installing the cleaning pad: The white side of the cleaning pad should be smoothly stuck to the machine, ensuring it doesn't cover the four detection holes to prevent air leakage.
Filling water into the water tank: Remove the water tank plug, fill with pure water or special glass cleaner (non-corrosive liquid recommended for better results, e.g., distilled water), and then tighten the plug. Corrosive liquids are forbidden.
Connecting to the power supply: Connect the machine's power cord to the adapter, then connect the plug's power cord to the adapter, and finally insert the plug into a power socket.
Fixing the safety rope: Check the safety rope for damage. If intact, fix it to a solid, reliable, and immovable object, leaving sufficient length for operation. It's recommended to circle the object 1-2 more times for enhanced safety.
Starting the machine: It is recommended to spray some window cleaner on the window first. Hold the power button for more than 1 second to power on. Once attached to the glass, release the machine and short-press the button to start cleaning. If the glass surface is very dusty, it's advised to wipe a clean area the size of the device before installation.

Path Planning:

"Z" pattern (Upright placement): When placed upright, the robot moves from the upper left to the upper right corner, measuring window width. It then moves to the next line, spraying water intermittently, and continues line by line until the window is clean. The space between lines is 1/3 of the machine's length. After cleaning, it returns to the starting area.
"N" pattern (Horizontal placement): When placed horizontally, the robot begins wiping in an "N" pattern. This pattern is recommended for windows with narrow frames. It moves rightwards to the right frame, then wipes upwards and downwards along the right frame, moving leftwards to the next line, and continues this pattern.

Water Spraying Function:

Defaults to wet-wiping mode upon power-on.
Dry wipe mode can be activated by pressing the water spray button on the remote control to turn off spraying.
In wet wiping mode, water is sprayed every 10-15 seconds, but not during edge detection or line changing.
The machine does not spray water when commanded to move via remote control (upwards/downwards/leftwards/rightwards).

Remote Control Functions:

Move to top, bottom, leftmost, rightmost.
Water spray ON/OFF (ON by default).
Wipe downwards from the current position.
Start/Pause/Continue.
Restart wiping.
Fixed point wiping.
Note: Remove remote control battery if not used for a long time to prevent aging/damage.

Safety Precautions:

Do not use in rainy, wet, or misty conditions.
Operate only between 0-40 degrees Celsius; use antifreeze glass cleaner below 0°C.
For external high-altitude use, implement ground safety warnings.
Do not use on cracked/damaged glass. Window frame thickness must be at least 6mm.
Window size must be larger than 40*60cm (height). Check for ultra-narrow, bevel, ultra-thin, or frameless windows, or uneven glass glue, bumps, leaks, gaps, as these conditions are not recommended or require supervision.
Keep product away from water, children, direct sunlight, high temperatures, humidity, or flammable materials.
Always check the safety rope for damage and ensure it's fixed to an immovable object.
Use a dry cleaning pad. Children should not operate the product.
Use cautiously on oblique surfaces with supervision; use remote control if necessary.
Shut down the machine before cleaning its surface.
Avoid rotating parts and openings when the machine is on. Unplug after use and during maintenance.
Follow the User Manual; contact customer service for faults.
Ensure battery is well-charged.
Do not use third-party chargers or disassemble/modify the machine, battery, or charger.
Discontinue use of damaged chargers; keep away from heat.
Transport in original packaging with the machine shut off.
For long-term storage, charge fully, turn off, and store in a cool, dry place. Recharge every two weeks to prevent over-discharge.
Dispose of batteries according to local laws/regulations.
Cut off power supply before battery removal for scrapping.

Maintenance Features

Regular maintenance is essential for prolonging the life and effectiveness of the HUTT W8.

General Maintenance:

Unplug and turn off the machine before cleaning the area beneath the cleaning pad.
After cleaning, drain water from the water tank.
Replace the used cleaning pad with a clean, dry one, or leave the machine without a cleaning pad.
After wet-wiping, place the machine in a dry, ventilated, cool place for 1-2 days to dissipate internal moisture.

Washing the Cleaning Pad:

Remove the cleaning pad.
Soak in water at approximately 20°C for 2 minutes.
Brush with a soft brush; do not rub or twist.
Allow to dry naturally before reuse.
Note: Do not use a wet cleaning pad to avoid slipping. Replace aged pads that cannot closely attach to the Velcro for best cleaning effect.

Cleaning the Bottom Component:

Bottom suction inlet: Wipe with a cleaning cloth to prevent blockage.
Anti-drop sensor: Wipe with a cleaning cotton swab to maintain sensitivity.
Water removing blades: Wipe with a cleaning cloth to keep them clean.

Cleaning the Crawler Wheels:

Avoid placing the machine directly on the floor after use to prevent particles from sticking to the cleaning pad or crawlers, which could scratch the glass.
If wheels are dirty, enable the wheel cleaning function: Hold the machine with the bottom suction inlet upwards, start the machine, press and hold the power button (crawler wheels will rotate slowly), then use a wet tissue to wipe off dirt.
Note: Do not clean crawler wheels with a cleaning cloth or dry towel.

Troubleshooting Guidance:

Machine slides downwards: Caused by excessive moisture in the cleaning pad. Absorb moisture with a paper towel, replace with a dry pad, or wipe water from crawler wheels and surrounding pad areas.
Machine holds on to the edge: Normal resistance detection; wait patiently.
Machine not moving smoothly: Replace cleaning pad or check for sticky residue on glass.
Removing an out-of-reach machine (no remote control): Pull the safety rope against the glass, slowly pulling the machine to reach it by hand.
Machine doesn't stop automatically: Remove the machine directly.
Unexpected power failure: Internal battery keeps machine attached for at least 20 minutes and triggers an alarm. Remove machine or restore power.

LED Indicators and Voice Prompts:
