Why does my Neakasa M1 Plus keep stopping mid-cycle?

The most common cause is clay dust mixing with the factory grease on the ring gear, forming a sticky paste that binds the gear teeth. When the motor hits a binding spot, the current spikes and the firmware halts the cycle. Cleaning the gear with degreaser and re-lubricating with dry PTFE spray solves it permanently.

Why does my Neakasa M1 Plus think a cat is inside when it's empty?

Fine dust suspended during a cleaning cycle drifts through the laser curtain on the upper rim. The laser picks up the particles as a reflection and the firmware interprets it as a cat crossing the boundary. Blasting the laser ports with compressed air and switching to a low-dust litter significantly reduces false detections.

Can I use regular grease on the Neakasa M1 Plus gears?

No. Wet grease or standard lithium grease will absorb clay dust and form the same abrasive cake that caused the original jam. Use only a dry-film PTFE (Teflon) spray lubricant, which forms a slippery layer without attracting or trapping dust particles.

Neakasa M1 Plus: drive gear stalls and laser sensor keeps triggering

The M1 Plus open-top design leaves the ring gear and laser curtain directly exposed to the air inside the litter chamber. Clay dust settles on both, jamming the gear mechanism and causing the laser safety sensor to treat dust clouds as a cat entering the unit.

01 — Why the gear jams and the laser triggers

Both failures are a direct consequence of the open-top design — components that would be sealed in other units are exposed to the air inside the litter chamber.

Dust mixes with the gear grease and jams the drive

The ring gear that drives the open sifting shell sits exposed at the top of the unit. Clay dust from the litter settles directly into the open gear teeth after every cycle. The factory-applied grease absorbs this dust and slowly transforms into a thick, abrasive paste. When the drive motor hits a section where the teeth are packed with this residue, it encounters increased resistance. The current spikes, the firmware interprets it as a jam, and the cycle halts — often mid-rotation, leaving the drum in an awkward position.

Dust clouds trigger the laser safety curtain

The M1 Plus uses a laser curtain across the top opening to detect if a cat enters while a cycle is running. When the sifting shell drops waste into the lower chute, it briefly kicks up a cloud of fine dust. These suspended particles pass through the laser beam and scatter the light in all directions — some of it reflects directly back into the detector. The firmware reads this momentary scattering as a cat crossing the boundary, freezes the cycle mid-rotation, and won't automatically resume. The app logs a "cat detected" error even though the unit is empty.

02 — Fix checklist

Part A cleans and re-lubricates the gear track. Part B clears the laser ports and recalibrates. You'll need a stiff nylon brush, electronic degreaser, dry-film PTFE (Teflon) spray lubricant, and a compressed air can.

Progress 0 / 6

Part A — Clean and re-lubricate the gear

Remove the outer trim panel

Unplug the unit. Unlatch the outer open-top trim assembly — it snaps on without tools — and lift it off. You'll see the ring gear running around the perimeter of the sifting shell and the smaller drive pinion that meshes with it. Look for areas where the teeth appear dark or packed with a sticky, gritty residue.

Remove the caked grease from the gear teeth

Spray a small amount of electronic degreaser onto the ring gear teeth. Work it in with a stiff nylon brush to break up the grease-and-dust cake. Rotate the sifting shell by hand as you go so you can reach the full circumference. Wipe everything dry with a lint-free cloth. The teeth should look clean and metallic when done.

Apply dry PTFE lubricant — not grease

Shake the dry-film PTFE spray (Teflon spray) and apply a thin, even coat across all the ring gear teeth and the drive pinion. Rotate the shell by hand to distribute it around the full circumference. Allow 2 minutes to dry. Unlike grease, PTFE dry film doesn't attract or bind airborne dust, so the gear won't cake up again after a few cycles.

Part B — Clear the laser ports and recalibrate

Blast the laser ports with compressed air

Look along the inner upper rim of the unit — you'll find several small recessed openings: the laser emitter ports and their corresponding receiver ports on the opposite side. Hold the compressed air can upright and blast each port with a short burst. Do not insert anything into the ports or touch the lenses directly.

Refit the trim panel and fill with low-dust litter

Snap the outer trim panel back on. Empty the litter bed if it's been sitting, then refill to the fill line with a low-dust clumping litter. Low-dust litter generates significantly less airborne particulate, which reduces both future gear contamination and false laser triggers. Plug the power cord in.

Reset the sensor baselines and run a test cycle

With the unit powered on and the litter bed filled, press and hold the Power button and the Wi-Fi button simultaneously for 5 seconds. The LED array will flash white to confirm the optical and weight sensor baselines have been cleared. Open the app and trigger one manual cycle to verify the sifting shell rotates smoothly to completion with no error.

Repeat the gear cleaning and PTFE re-application every 2–3 months to prevent caking from building up again.

03 — Replacement hardware

If stalls continue after a full gear clean and re-lubrication, the drive pinion or motor may have accumulated mechanical wear that cleaning can't reverse.

Replacement option

Neakasa M1 Plus

A replacement unit comes with a fresh gear assembly. Starting with PTFE lubrication from the first use — instead of the factory grease — will significantly extend the service life before the next clean is needed.

04 — Advanced: Wi-Fi stability

For units that drop offline intermittently, especially on networks with multiple access points.

Locking the unit to a fixed access point

On networks with multiple access points, the controller can move the M1 Plus to a different access point while it's mid-cycle. The unit's firmware doesn't handle the brief reconnection cleanly — it drops the cloud connection and doesn't automatically reconnect. The unit finishes the physical cycle but shows as offline in the app until the next power cycle.

If your mesh or enterprise wireless controller supports client pinning (sometimes called "sticky clients," "BSSID lock," or "disable roaming"), find the M1 Plus's MAC address in the device list and lock it to the nearest access point. This prevents roaming interruptions entirely.

If pinning isn't available, assigning a static DHCP reservation for the M1 Plus helps reduce reconnection failures by ensuring it always gets the same IP address, which makes reconnect attempts faster and more reliable.

Disabling legacy Wi-Fi speeds on your IoT network

When old 802.11b devices (or devices pretending to be slow for compatibility) are on the same Wi-Fi network, the access point has to slow down all management traffic to accommodate them. This airtime overhead can delay the M1 Plus's brief data bursts, causing missed check-ins with the cloud.

In your router or access point settings, find the minimum data rate control for your IoT SSID and set it to 11 Mbps or higher. This disables 802.11b legacy speeds and ensures management frames don't slow down the entire channel. It's a common setting on routers marketed as "gaming" routers and on enterprise access points like UniFi and Meraki.
