Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.
Litter-Robot is the flagship product line of Whisker, a U.S. pet-technology manufacturer focused primarily on connected and automated cat-care equipment. The company was founded around Brad Baxter's original self-cleaning Litter-Robot in 2000 and has since expanded into automatic feeders and other connected pet-care products. Its best-known products are the Litter-Robot series of automatic self-cleaning litter boxes, which use electromechanical waste-separation systems, sensors, and app connectivity to automate litter-box maintenance and provide pet-activity insights. Whisker designs its products primarily in Michigan and manufactures/assembles its robotic products in Juneau, Wisconsin, while sourcing some components globally. The company says more than 1.5 million pet owners use its automated-care products worldwide.
The anti-pinch contacts or sensors become dirty, corroded, obstructed, or electrically unreliable, causing false pinch-detect errors and stopping the globe mid-cycle. This is especially common on Litter-Robot 3, but pinch-detection faults also occur on later models.
DFI optical sensors become contaminated, obstructed, or fail electrically, causing the robot to report a full waste drawer when it is partially filled or empty. Sensor residue, liner positioning, and failed DFI electronics are common causes.
Bonnet electrical contacts, sensors, or fitment become unreliable, producing repeated "Bonnet Removed" errors even when the bonnet is installed. Poor contact, warped components, worn connectors, or globe movement can interrupt the bonnet circuit.
The drive motor stalls, strains, becomes noisy, or cannot rotate the globe, producing motor or over-torque faults. Excess litter, mechanical drag, worn gears, debris, or a failing motor assembly can leave the globe stuck mid-cycle.
Hall-effect or position-sensing systems fail to correctly identify the globe's home or dump positions. The unit may repeatedly stop, reverse, display position faults, or remain with the globe rotated away from its normal home position.
The weight or cat-presence sensor becomes inaccurate, overly sensitive, or fails to recognize a cat entering the globe. This can cause missed automatic cycles, repeated cycle interruptions, false cat detections, or inaccurate recorded cat weights.
Litter-Robot 4 and later models can develop faults in the optical curtain or OmniSense laser sensors used for cat detection and waste-level monitoring. Dust, litter debris, contamination, alignment problems, or sensor-board failure can cause false detections and prevent normal cycling.
The motor pinion or globe gear track becomes loose, worn, misaligned, or damaged, resulting in jerky rotation, slipping, grinding, or failure to complete a cycle. Severe drive problems can trigger motor-overload or globe-position errors.
The main circuit board, wiring harness, connectors, or sensor-board electronics can develop intermittent or permanent electrical faults. Symptoms include no power, unexplained multiple sensor errors, nonresponsive controls, erratic cycling, or repeated faults that persist after individual sensors are serviced.
