Question 1

the dirty water tank fills up way too fast, like after one small mopping job, but the floor wasn't that dirty.

Accepted Answer

DIAGNOSIS The dock's auto-empty function for the *mop* water isn't working, or the robot is incorrectly reporting a full tank. The system is designed to pump dirty water back after cleaning, but a sensor or pump issue can cause premature 'full' readings. FIX Manually check and reset the system. Empty the dirty water tank. In the app, go to Dock Settings and run the "Dock Self-Clean" function. This cycles the internal pumps and can clear airlocks or minor clogs in the water lines. IF THAT DIDN'T WORK Inspect the rubber seals and connectors. Where the clean and dirty water tanks connect to the dock, look for kinked tubes or debris on the rubber gaskets. A bad seal can cause the water system to malfunction. HEADS UP This is often a software glitch. Ensure your app and dock firmware are fully updated. A recent update specifically addressed water tank reporting accuracy.

Question 2

the robot keeps getting lost and says 'positioning failed' in the middle of a clean.

Accepted Answer

DIAGNOSIS The LIDAR sensor on top is dirty or obstructed, or there's inconsistent lighting (like very bright direct sunlight) confusing its maps. FIX Clean the LIDAR turret. Power off the robot. Gently spin the clear plastic dome on top and wipe it with a dry microfiber cloth. Ensure no tall, thin objects (like floor lamp poles) are near the dock, as they can create a 'blind spot'. IF THAT DIDN'T WORK Delete and remake your map. In the app, go to Map Management, delete the current map, and start a full cleaning cycle with all doors open and consistent lighting. Don't interact with it until it finishes and saves the new map. HEADS UP Highly reflective surfaces (large mirrors, glossy black floors) can also scatter LIDAR signals. If you have them, the robot may always be slightly unstable in those areas.

Question 3

it's making a loud grinding noise when it's vacuuming, sounds like it's coming from the roller.

Accepted Answer

DIAGNOSIS A foreign object (like a rock, piece of Lego, or large staple) is caught in the main roller brush chamber, or the roller bearings are failing. FIX Immediately stop the robot and flip it over. Remove the main roller brush by pressing the two release clips on the ends. Inspect the roller and the chamber it sits in for any hard debris. Clear it out. IF THAT DIDN'T WORK Manually spin the roller with your hand. If it grinds or feels gritty without any debris present, the roller unit itself is damaged. Order a replacement main roller assembly. HEADS UP Running it with this noise can damage the motor gearbox. Always do a quick visual sweep for large debris before sending it into a new room.

Question 4

my narwal freo won't connect to wifi during setup, it just times out.

Accepted Answer

DIAGNOSIS The robot/dock only connects to 2.4GHz networks. If your router broadcasts a combined 2.4/5GHz SSID or uses certain security protocols (like WPA3-only), it will fail. FIX Temporarily split your WiFi bands. Log into your router and create a separate, dedicated 2.4GHz network with a simple name and password (no special characters). Connect your phone to *that* network, then run the Narwal app setup again. IF THAT DIDN'T WORK Move the dock closer to the router during setup, and ensure your phone's Bluetooth is on. The initial handshake uses Bluetooth, but a weak signal can break it. HEADS UP Once set up, the robot uses the dock as a WiFi repeater. If the dock is in a poor signal area, the whole system will be unstable. Permanent placement matters.

Question 5

the vacuum suction seems really weak all of a sudden, it's not picking up crumbs.

Accepted Answer

DIAGNOSIS A clog in the air path or a full/faulty dust bag is killing suction. The most common spot is the channel where the robot empties into the dock. FIX Clear the main dust pathway. Remove the robot's dustbin and check for clogs. Then, power off the dock, remove the dust bag, and use a long, thin object (like a chopstick) to clear any debris from the dock's emptying port where the robot connects. IF THAT DIDN'T WORK Check the side brush and main roller. Manually spin the main roller—if it doesn't move freely, hair is wound around the axles. Use the provided cleaning tool to cut and remove all wound debris. HEADS UP The dust bag can appear not-full but still be compacted at the bottom, blocking airflow. Replace the bag if it's been over a month, even if the app doesn't say it's full.

Question 6

the dock is giving me an error that says 'cleaning tank not installed' but it's definitely in there.

Accepted Answer

DIAGNOSIS The dock's sensors aren't detecting the clean water tank, usually due to a misaligned tank, debris on the contacts, or a faulty float sensor inside the tank. FIX Remove and reseat the tank firmly. Take out both the clean and dirty water tanks. Check the clean tank's bottom for the metal contact pins—wipe them and the corresponding slots in the dock with a dry cloth. Reinsert the tank until you hear a definitive click. IF THAT DIDN'T WORK Inspect the tank's internal float sensor (the white plastic piece that moves up and down). Gently move it to ensure it's not stuck. Try filling the tank to only 80% capacity, as an overfilled tank can sometimes jam the float. HEADS UP This error will prevent any mopping or auto-refill functions. If reseating doesn't fix it, you likely need a replacement clean water tank—contact support with your dock serial number.

Question 7

the robot is mopping but leaving streaks and wet lines on my floor, it's not drying properly.

Accepted Answer

DIAGNOSIS The mopping pads are either too wet, dirty, or the robot's drying station isn't activating the hot air cycle correctly. This is a common gripe with the auto-drying feature. FIX Manually trigger a drying cycle. In the app, go to the Dock settings and press "Dry Mopping Pads." Let it run the full 2-hour cycle. While it runs, remove the pads, hand-wash them with mild detergent, and let them air dry completely before reattaching. IF THAT DIDN'T WORK Check the water tank setting. In the app, for your saved floor plan, ensure the water flow isn't set to "High" for sealed hard floors. Try a "Medium" or "Low" setting for less moisture. HEADS UP The hot air drying only works if the pads are *centered* on the docking station trays. After the robot docks, visually confirm both pads are fully seated on the heated vents.

Question 8

my narwal freo x ultra just keeps beeping and flashing a red light, it won't start cleaning.

Accepted Answer

DIAGNOSIS The robot is stuck in an error state, usually because it can't see or its bumper is jammed. The red light is a general alarm. FIX Power cycle the robot first. Pick it up, press and hold the physical power button on the side for 10 seconds until it fully shuts off. Wait 30 seconds, then press the button again to turn it back on. IF THAT DIDN'T WORK Check for physical obstructions. Remove the front bumper by gently pulling it away from the body and clean behind it. Wipe the LIDAR turret on top and all cliff sensors (the black windows around the bottom) with a dry microfiber cloth. HEADS UP If the red light persists after this, the error is likely internal. You'll need to note any specific flash patterns and contact Narwal support—they'll ask for a video.
