The essentials
  1. Remove excess litter down to the raised MAX fill line — the single most common cause.
  2. Remove the Bonnet and Globe and check for damage, a loose carbon filter cover, or peeling seal strips.
  3. Inspect the motor — confirm the motor cover is screwed down and the gear doesn't spin freely.
  4. Run a motor-only test without the Globe installed; contact Whisker Customer Experience if it's still jammed.
Before you start
  • The globe stops mid-rotation and retracts then pauses briefly and tries again on its own.
  • After three failed attempts, it gives up the globe stops moving and the LED Indicator Light turns Blinking Red.
  • The LCD screen shows "Overloaded Globe" confirming this specific fault rather than a different one.
What this means for your pet

Your cat may have no usable box right now. Cats that can’t get in will hold it or find another spot in the house — put a spare tray down before you start, so nothing depends on how fast this goes.



What happens when the globe meets resistance

The manual describes the behavior in one paragraph: "If the Globe becomes jammed or overloaded during rotation, the Motor will stop and retract briefly. After a short pause, the unit will attempt to continue the cycle. If the Globe is unable to continue the cycle after three attempts, the Globe will stop and the LED Indicator Light will change to Blinking Red." If the Globe does complete the cycle despite a jam, the unit simply returns to normal operation with no further action needed.

Cause 01

It retries three times before giving up

A single stop-and-retract isn't a fault — it's the globe working through resistance on its own. Only after three failed attempts does the unit lock into Blinking Red and stop trying.

Cause 02

Most cases never need a teardown

The two most common causes — overfilled litter and debris on the Dual Pinch Bars — are both visible without removing a single part. Check those first before working through Whisker's full checklist below.

Once the LCD is actually showing an "Overloaded Globe" notification, work through the checklist below in order.


Whisker's teardown checklist, step by step

Follow these in order — most jams clear in the first two steps, before you need to touch the motor.

Your progress 0%
Part A — Litter and obstructions
Part B — Inspect and test the motor

Keep the gear track and base free of debris

Compressed air is the fastest way to clear litter dust from the top of the base and the Dual Pinch Bars before you inspect further.

If it's still jammed: what to buy

If the motor-only test still fails, the official guidance is to contact Whisker Customer Experience for motor replacement assistance — the manual gives the same escalation path more generally: "If the problem persists, visit whiskersupport.com for more information." Before that call, these two consumables prevent the large majority of Overloaded Globe cases from happening again.

Now that you know how to clear a jam, the two causes below explain why it happens in the first place.


The two causes that show up before you ever open the unit

Litter overfill — the single most avoidable cause

The manual's fill guidance exists specifically to prevent this: about 0.8 gallons (3L), roughly 8.8 lbs (4 kg) of clumping clay litter, filled flat to the raised MAX line — "be careful not to overfill the globe." Litter above that line adds enough resistance during rotation to trigger the fault, especially as it compacts over a few days of use.

Litter buildup on the Dual Pinch Bars

The manual flags this separately under Obstruction Detection: "Ensure Dual Pinch Bars are clear of excess litter." A cycle that repeatedly stops, retracts, and retries — without ever reaching the three-attempt failure that locks the light red — is usually this, not a true Overloaded Globe fault. A can of compressed air along the waste drawer chute is the fastest way to clear it.


Frequently asked questions

Why does my Litter-Robot EVO globe keep stopping and retracting?

It has met resistance during rotation — usually overfilled litter or debris on the Dual Pinch Bars. The unit retries automatically up to three times before locking into Blinking Red.

What does "Overloaded Globe" mean on a Litter-Robot EVO?

It means the globe couldn't complete a full rotation after three attempts, so the motor stopped and the LED Indicator Light turned Blinking Red. Whisker's checklist walks through litter level, physical obstructions, and the motor, in that order.

How much litter should I put in a Litter-Robot EVO?

About 0.8 gallons (3L), roughly 8.8 lbs (4 kg) of clumping clay litter, filled flat to the raised MAX line. Overfilling is the single most common cause of an Overloaded Globe fault.

My Litter-Robot EVO globe won't rotate at all — what should I check?

Start with litter level and the Dual Pinch Bars, then remove the Bonnet and Globe to check for damage or a loose carbon filter cover. If a motor-only test (Bonnet on, Globe off) still doesn't turn the gear cleanly, contact Whisker Customer Experience.


Conclusion

Overloaded Globe on the Litter-Robot EVO almost always starts with too much litter or debris on the Dual Pinch Bars — check the MAX fill line and clear the pinch bars before opening the unit. If it's still jammed, Whisker's own checklist walks through the Bonnet, Globe, carbon filter cover, seal strips, and motor cover, in that order, before recommending a support contact for motor replacement.

Still not fixed? Here’s what to do next.

Some faults are genuinely hardware, and no amount of cleaning or resetting will clear them. If you’ve worked through everything above and it’s still doing it, stop here rather than taking the unit further apart.

  • Go to Whisker (Litter-Robot) directly. If the unit is still under warranty, let them replace the part rather than paying for it yourself — contact Whisker (Litter-Robot) support.
  • Tell us what didn’t work. We rewrite bulletins when readers show us a case they don’t cover — compliance@pet-infrastructure.com. Tell us the model, what the lights are doing, and which steps you already tried.
  • Ask other owners. r/litterrobot is active and full of people who have had the exact same fault on the exact same model. Search the sub before posting — the answer is often already there.

When to stop and call the manufacturer: if the fix needs the base opened, the motor or control board touched, or any tool beyond a screwdriver — stop. On a unit in this price range, opening it yourself usually voids the warranty, and a warranty repair costs nothing.
