Let’s talk about maintaining the robot vacuum’s wheels—because if they’re not clean, your vacuum might start acting up. Here’s how to keep them in great shape:
Step 1: Check the Wheels
Flip your vacuum over and take a look at the main wheel, side wheels, and caster wheel. You’ll probably see hair, dust, or debris wrapped around them—this is totally normal, especially if you have pets or long hair.
Step 2: Clean the Wheels
-
Use your fingers or a pair of tweezers to pull out any hair or string wrapped around the wheels.
-
For stubborn dirt, try using a small brush or compressed air to blow out the gunk.
-
If the wheels are really dirty, wipe them down with a damp cloth (just make sure they’re dry before using the vacuum again).
Step 3: Spin the Wheels
After cleaning, give the wheels a spin to make sure they’re moving freely. If they feel stiff or stuck, there might still be debris hiding inside—time to grab those tweezers again!
How Often Should You Clean Them?
Aim to clean the wheels every two weeks, or more often if you’ve got pets or a lot of carpet. Regular cleaning keeps your vacuum moving smoothly and prevents wear and tear.
Keeping Your Robot Vacuum’s Sensors Sharp
Robot vacuum maintenance tips include regular sensor cleaning, especially for advanced models like the Narwal Freo Z Ultra. Dirty sensors can lead to common problems like poor navigation or getting stuck, so include them in your routine maintenance checklist. If they get dirty, your vacuum might start acting lost or confused. Here’s how to keep them working perfectly:
Step 1: Find the Sensors
Flip your vacuum over and look for the cliff sensors (usually small, round sensors on the underside) and the navigation sensors (often located on the top or sides). These are the spots that need your attention.
Step 2: Clean the Sensors
-
Use a soft, dry cloth to gently wipe the sensor surfaces. Avoid using water or cleaning products—they can damage the sensors.
-
If there’s stubborn dirt, you can lightly dampen the cloth with water, but make sure the sensors are completely dry before using the vacuum again.
Step 3: Check for Obstructions
While you’re at it, make sure nothing’s blocking the sensors, like dust or debris. A quick wipe should do the trick!

If you’re not using the vacuum for a while (like a vacation), store it with about 50% charge. Too much or too little charge can hurt the battery over time.
Avoid Over-Discharging
Letting the battery drain to 0% too often can shorten its lifespan. Try to recharge it when it hits around 20-30%. Most robot vacuums will alert you when the battery’s low, so keep an ear out for that beep!
When to Replace the Battery
Even with great care, batteries don’t last forever. If you notice your vacuum isn’t holding a charge like it used to, or it’s running out of juice way too fast, it’s probably time for a new battery. Replacing it is usually simple:
-
Turn off the vacuum and remove the battery (check your manual for the exact steps).
-
Insert the new battery, making sure it’s securely in place.
-
Charge it fully before using the vacuum again.
Quick Tips for Battery Longevity
-
Charge it regularly, but don’t leave it plugged in 24/7.
-
Keep the vacuum in a cool, dry place—heat can damage the battery.
-
Replace the battery every 2-3 years, depending on usage.
Models with larger batteries, such as Narwal Flow’s 6400mAh pack, can run longer on a single charge. Still, the same rules apply: avoid full discharges, keep the vacuum in a cool place, and recharge before it hits 0%.
