The Big Clean — Self-Cleaning Cat Litter Box, App-Controlled WiFi, 15-Day Hands-Off

Placement: Place the litter box on a hard, flat surface with all four feet touching the ground. Leave at least 70cm of height clearance and 80cm of depth clearance above and behind the unit so the waste bin can open fully. If you need to move it, unplug it first and move the whole unit via the clasp under the base — never lift or move it by the barrel alone.

Power on & self-test: Use the original adapter only, and make sure the socket supplies a stable voltage. The unit completes a self-test within 6 minutes of being powered on. Auto mode is enabled by default once the self-test finishes, and the Auto lamp lights up — the box is then ready for normal use.

Safety note: Don't move the box while it's powered on. Lifting it for more than 5 seconds triggers the gravity protection lock, which pauses all cleaning and litter-replacement actions until you either manually level the litter or wait 30 minutes for an automatic recalibration.

Adding litter: Add litter through the entrance up to the MAX line marked on the grey soft section inside the barrel — going over this can cause spillage and litter filtering into the mechanism. For day-to-day top-ups, keep it closer to the MIN line, which reduces litter sticking to the base.

Levelling: After adding litter (0.6kg or more), press and hold "Remove Odour" for 2 seconds to smooth the litter, then carry out any further actions.

Sand surface calibration: Different litters sit differently in the barrel. In the app, open Settings and select "Sand surface calibration." The default value is 3 on a 0–6 scale — increase it if the right side of the litter surface (facing the box) sits low, decrease it if the left side sits low. After each single-point adjustment, press "Remove Odour" for 2 seconds to re-level and check the surface is horizontal.

1. Download the "Tuya" app from your phone's App Store.
2. Confirm your phone is connected to 2.4GHz WiFi (not 5GHz), then turn on Bluetooth and Location.
3. Open the Tuya app and tap "Add device."
4. Press and hold "Auto" on the panel for 2 seconds — the WiFi lamp will start flashing, meaning the box is trying to connect.
5. Once connected, enter the app to access all remote controls and settings.

If the app won't connect: double-check you're on 2.4GHz not 5GHz, confirm phone Bluetooth is on, check the WiFi lamp is flashing during connection, make sure your home WiFi is working normally, re-check your WiFi password, and make sure your router isn't overloaded with too many connected devices.

Auto Clean: Press "Auto" to turn on Auto Clean — the box will automatically clean itself once your cat leaves. The default wait time before cleaning is 3 minutes, with a 15-minute gap enforced between two cleans. Both are adjustable in the app (wait time 0–60 min, gap 0–120 min).

Important: if you have kittens under 1kg or a pregnant cat, use manual "Clean" only and don't use Auto Clean mode, since the weight sensors are calibrated for adult cats.

Timing Clean: Set a scheduled cleaning start time and cycle via the app, for households that prefer a fixed routine over reactive auto-cleaning.

Manual Clean: Tap "Clean" to trigger an immediate clean. Make sure your cat isn't in the barrel first — the unit calibrates weight before cleaning, and won't run if it detects your cat inside.

Remove Odour: Tap "Remove Odour" to start a 30-minute odour removal cycle using the built-in ion purification module (this produces a small, safety-standard-compliant amount of O₃). You can also schedule regular odour removal times via the app.

Do Not Disturb: Set quiet hours in the app. During this window the panel display and lights go dark and Auto Clean is disabled, so the box won't run noisily overnight. Any scheduled cleans or odour-removal cycles already queued will finish first before Do Not Disturb takes effect.

Child lock: Press "Auto" + "Remove Odour" together for 2 seconds to lock the panel — the box keeps running its programmed schedule, but the physical buttons are disabled. Press the same combination again to unlock. Can also be toggled from the app; unlocking the panel doesn't affect app control.

Infrared sensor: Off by default. If turned on, it may trigger frequently near reflective flooring (bright tiles, glass) within roughly 30cm of the unit — if that happens, either disable the sensor or reposition the box.

Press "Clean" for 2 seconds — the bin rotates to the bag-changing angle and stays there for 60 seconds. Remove the used bag, wrap the new bag's opening around the bin's door frame, pull the drawstring through, press it into the tie-up clip, tighten, and wind it closed. Finish by tucking the bag's back edge out of the way of the lid and confirming the buckle is fastened before running the unit again.

Full indicator: The Full lamp is a reference-only prompt — if it lights early or late for your litter type, you can recalibrate the "capacity calibration" range in app settings (0–7 for tofu/mixed litter, 5–10 for bentonite, 8–15 for mineral).

Replace the bag roughly every 3 days in summer and every 7 days in winter for hygiene, or sooner in a multi-cat household.

Replace litter: Fit a new waste bag first, then press "Replace litter" for 2 seconds. The box collects all remaining litter from the barrel into the bag for you, ready for a full clean or a barrel move.

Cleaning & installation: Empty the barrel and waste bin, disconnect power, open the barrel buckle and lift it off. The barrel and waste bin can be washed with water — but the base must never be washed, since it houses the electrical components; wipe it with a damp cloth only. After cleaning, dry everything, reinstall the barrel into its fixed slot, close the buckle, confirm the waste bin is shut, then power back on and wait for the self-test before resuming use.

Do not remove the filter or the grey soft padding inside the barrel during cleaning, and if you remove the yellow rubber plug (for the urine-leakage vent) to clean it, remember to refit it afterwards.
