2. Initial Placement and Power On

  • Place the assembled litter box on a hard, level surface. Avoid carpets or soft flooring.

  • Add clumping cat litter to the drum, ensuring it does not exceed the 'MAX' fill line.
  • After powering on and adding new litter, run the "Level" mode to calibrate the litter box. This ensures proper operation and accurate weight monitoring.

3. App Connection

  • Download the UPFAS app from your smartphone's app store.
  • Open the app and follow the on-screen instructions to connect your litter box using 2.4GHz Wi-Fi or Bluetooth.
  • Ensure your Wi-Fi network is 2.4GHz, as the device does not support 5GHz networks.

Operating Instructions

1. Automatic Cleaning

The litter box is designed to automatically detect when your cat has used it and initiate a cleaning cycle after a set delay. This delay can be adjusted via the app to allow sufficient time for clumps to form.

The cleaning operation is ultra-quiet, with noise levels below 35 dB, ensuring a peaceful environment for your home and pets.

2. Smart App Control

The UPFAS app provides comprehensive control and monitoring features:

  • Real-time Monitoring: Track your cat's health with detailed usage history, including weight, time spent in the box, and frequency of use.
  • Scheduled Cleaning: Set specific times for cleaning cycles.
  • Adjustable Cleaning Frequency: Customize how often the box cleans.
  • One-touch Cleaning: Initiate a cleaning cycle manually from the app.
  • Temporary Disable Auto-cleaning: If your cat is sensitive to movement, you can temporarily disable automatic cleaning and run it manually.

3. Safety Features

  • Anti-Pinch Design: The design prevents accidental pinching, even for small fingers.
  • Real-Time Gravity Sensor: The litter box is equipped with sensors that detect the presence of your cat. If a cat enters during a cleaning cycle, the operation will pause immediately and resume only after the cat has exited.

Maintenance

1. Emptying the Waste Bin

The waste bin should be emptied regularly, typically every 2-3 days depending on usage. Simply lift the upper lid, remove the filled waste bag, and replace it with a new one.

2. Routine Cleaning

The litter box's intuitive design makes routine cleaning straightforward:

  • Drum Cleaning: The drum features a snap-free design, allowing you to easily lift it from the base for cleaning. The drum part is fully washable with water.
  • Lining Material: The drum is lined with a double-layer polymer fabric (polymer composite fabric + polymer coating) that is scratch-resistant, anti-stick, and prevents leakage. Only the surface of the fabric will get wet, ensuring water does not enter the drum's internal mechanisms.
  • Base Cleaning: Wipe down the main body base with a damp cloth. Avoid getting water into electronic components.

3. Deep Cleaning

Periodically, a more thorough cleaning may be necessary. After emptying the litter and waste, disassemble the drum as per assembly instructions, rinse all washable parts with water, and allow them to dry completely before reassembly. Wipe down the entire unit with a pet-safe cleaner.

Troubleshooting

Problem Possible Cause Solution
Litter box stuck in tilted position. Waste bin is too full; firmware issue; uneven surface.
  • Empty the waste bin.
  • Check for available firmware updates via the app.
  • Ensure the litter box is on a firm, level surface.
  • Unplug and replug the device to reset.
Litter sticking to the bottom of the drum. Insufficient time for clumps to harden; litter type.
  • Adjust the cleaning delay in the app to allow more time for clumps to form (e.g., 120 seconds or more).
  • Ensure you are using high-quality clumping cat litter.
  • Manually scrape any stuck litter before the next cycle.
Small clumps remain in the litter after cleaning. Litter grate slots are wide; very small clumps.
  • This can be a characteristic of the grate design. Manually remove any remaining small clumps as needed.
  • Ensure the litter level is correct; overfilling can affect grate movement.
Odor persists despite cleaning. Infrequent deep cleaning; poor ventilation; litter type.
  • Perform a deep clean of the entire unit, including washing the drum and wiping the base.
  • Ensure the waste bin is emptied frequently.
  • Consider using a higher quality, odor-controlling clumping litter.
  • Place the litter box in a well-ventilated area.
Litter scattered outside the box. Cat behavior; litter type; litter level.
  • Ensure the litter level is not too high.
  • Consider using a litter mat around the entrance.
  • Some cats are naturally messier; this may require more frequent sweeping around the unit.
Cat refuses to use the litter box. New device; preference for traditional box; size.
  • Introduce the new litter box gradually, keeping a traditional box available initially.
  • Ensure the litter box is clean and filled with familiar litter.
  • Confirm your cat's weight is within the recommended range (3.5-15 lbs).
