Pet detection is inaccurate

Last updated: August 19, 2026
Applicable model: Popur S7 Split Litter System (SLS)
Applicable firmware version: 4.0.0 & onwards
Applicable mobile app version: 2.0.0 & onwards (both Android & iOS)

🔍 Troubleshooting Suggestions

Automatic cleaning is no doubt the core function of the system, which depends on detecting pets correctly in different scenarios. Inaccurate pet detections can be categorized into these two groups:

  1. Pet is present but it says not detected, i.e. falsely reporting Pet left without business.
  2. Pet is absent but it says detected, i.e. falsely reporting Pet detected, Pet doing the business, or Pet finished the business.

As a first step, kindly ensure the firmware is updated to version 4.0.0 or newer, and app is updated to version 2.0.0 or newer. Here's the firmware update guide.

Please make sure your unit is in the default Automatic mode (indicated by purple light) as opposed to green or blue color for manual operation.

Double check the status of and fully comprehend the definition of these features because each of them has an effect on the activiation of an automatic cleaning cycle: Schedule, Do-not-distrub, Caring, Linger, Zoomie, No-troll, Sensitivity, Range, Anti-interference, Delay, Allow overfill, Block on full, and Detect pets. Technical clarifications are detailed in the Cleaning Modes section on the Product Resources page. Below is a quick summary:

  • Schedule: Cleaning will start at predetermined timestamps.
  • Do-not-disturb: Cleaning will NOT start during the DND hours.
  • Caring: Cleaning is easier to trigger.
  • Linger: Cleaning is harder to trigger because it requires a confirmed weight change.
  • Zoomie: Cleaning is MUCH easier to trigger.
  • No-troll: Cleaning will NOT start after a completed cycle.
  • Sensitivity: Cleaning is easier to trigger for higher value.
  • Range: Cleaning is easier to trigger for higher value.
  • Anti-interference: Cleaning is MUCH harder to trigger.
  • Delay: Cleaning will start after the predetermined countdown.
  • Allow overfill: When toggled off, cleaning will NOT start if bin is full.
  • Block on full: When toggled on, cleaning will NOT start if bin is full.
  • Detect pets: Cleaning is harder to trigger because of additional weight change requirements.
For Scenario 1: NO Automatic Cleaning / False 'Pet left without business'

Please consider the following options:

  • INCREASE cat sensor sensitivity (default value 5) or range (default value 3) in Popur S7 App → Device Page → Top-right icon for Settings → Detect
  • Activate Caring mode in Popur S7 App → Device Page → Modes menu → Caring
  • Activate Zoomie mode in Popur S7 App → Device Page → Modes menu → Zoomie
For Scenario 2: RANDOMLY Cleaning / False 'Pet finished the business'

Please consider the following options:

  • DECREASE cat sensor sensitivity (default value 5) or range (default value 3) in Popur S7 App → Device Page → Top-right icon for Settings → Detect
  • Activate Linger mode in Popur S7 App → Device Page → Modes menu → Linger
  • Activate Anti-interference in Popur S7 App → Device Page → Detect → Anti-interference

After these adjustments, please conduct a quick sensor test by gently waving your hand above the litter bed to simulate a cat's movement. Please continue the motion for at least 10 seconds to ensure a sustained trigger. Under normal operation, the purple status light will react in the following sequence:

  1. Blink purple to indicate motion detection;
  2. Spin once a while (approx. every 6 seconds) to confirm the trigger;
  3. Switch to a breathing pattern, signaling that a cleaning cycle is timed.

If the purple light blinks randomly or never blinks, a new cat sensor will be needed.

🪛 Repair or Replacement

If you are constantly experiencing inaccurate pet detections, including either NOT or FALSELY reporting, please consider replacing the cat sensor to resolve the issue once and for all. Feel free to keep the motherboard as backup and skip the corresponding section in the video, as it is not applicable to the present issue.
