Check more often if you use vacuum-and-mop mode frequently. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/01-main-roller-and-brush-compartment.jpg) ### Side Brush Gear Clear wrapped hair and strands from the [side brush](https://www.amazon.com/dp/B0FFB1ZK2M?tag=vacubots-20&ref=vacubots.com) gear housing. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/02-side-brush-gear.jpg) ### Wheels Clear hair and debris that have wound around the axles. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/03-wheels.jpg) ## Water Tanks, Dustbin and Filters (Weekly) ### Dirty-Water Tank Empty and clean to remove residue and prevent odors. Dish soap works for a deeper clean. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/04-dirty-water-tank.jpg) ### Clean-Water Tank Rinse as needed. Remove the scale inhibitor first if using soap. Upon refill, Narwal [cleaning solution](https://amazon.com/dp/B0FFGD8XXV?tag=vacubots-20&ref=vacubots.com) should be used as directed. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/05-clean-water-tank.jpg) ### Dustbin Empty and wipe out collected dust. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/06-dustbin.jpg) ### Underneath Dustbin Area Make sure the intake port and suction grid are clear of hair, dust and debris. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/07-underneath-dustbin-area.jpg) ### Main Filter Clear dust from the [filter](https://amazon.com/dp/B0CQ8HMR16?tag=vacubots-20&ref=vacubots.com) with a handheld blower to maintain airflow. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/08-main-filter.jpg) ### Prescreen Filter Check closely. This one clogs with fine debris the fastest. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/09-prescreen-filter.jpg) ## Sensors, Dock, Mop Pad and Dust Bag (Monthly) ### Top Sensors Wipe clean whenever dust or debris is visible. The front camera sensors handle obstacle avoidance, and the side sensor measures distance. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/10-top-sensors.jpg) ### Bottom Sensors These are the fall sensors. Wipe clean whenever dust or debris is visible. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/11-bottom-sensors.jpg) ### Washboard and Dock Basin Give both a more thorough clean. Loosen dried residue with a little hot water before scrubbing. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/12-washboard-and-dock-basin.jpg) ### Mop Pad Inspect the [track mop](https://amazon.com/dp/B0FFB733VQ?tag=vacubots-20&ref=vacubots.com) for wear and replace it if needed. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/13-mop-pad.jpg) ### Track Mop Housing Check the area for dirt, debris and residue. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/14-track-mop-housing.jpg) ### Scraper and Mop Roller Check for dirt, hair or residue that could interfere with the roller-cleaning system. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/15-scraper-and-mop-roller.jpg) ### Dust Bag Confirm the [dust bag](https://amazon.com/dp/B0GK6GJNPV?tag=vacubots-20&ref=vacubots.com) is seated correctly and isn't full. Gently shake it to settle debris. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/16-dust-bag.jpg) ## Deep Clean (Every 1–3 Months) ### Roller Compartment Watch for dark, damp residue if you mop often. Let it fully dry between uses to avoid mold. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/17-roller-compartment.jpg) ### Track Mop Housing Corner Wipe out the corner where the mop-roller track meets the housing. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/18-track-mop-housing-corner.jpg) ### Area Under the Track System This open space is easy to miss but collects dirt readily. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/19-area-under-the-track-system.jpg) ### Drain Area With the washboard removed, clear hair, lint or dried mud from around the drain. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/20-drain-area.jpg) ### Dock Ramp Wipe down the ramp's ridges and grooves so the robot docks smoothly. ![](https://storage.ghost.io/c/69/d5/69d51699-d072-45ac-9ab4-d45efbe74012/content/images/2026/09/21-dock-ramp.jpg)
