What are the Roborock Sensors and Why Do They Need Cleaning?
Roborock robotic vacuums rely on a set of infrared cliff sensors located underneath the unit to detect and avoid falls down stairs or over ledges. These sensors emit infrared signals to determine when the vacuum is approaching a sharp drop-off. This allows the Roborock to change course and avoid potential damage or accidents.
Over time, dirt, dust, hair, and debris can accumulate on the sensors. This buildup can interfere with the infrared signals, preventing the sensors from working properly. As a result, the Roborock may not detect cliffs or drops, increasing the risk of falls and impact damage.
Regular cleaning keeps the sensors free of occluding material so they can continue detecting cliffs and navigating safely. Clean sensors are essential for optimal effectiveness and accident avoidance.
How Often Should You Clean Roborock Sensors?
Roborock recommends cleaning sensors at least once per week. More frequent cleaning, such as after every use, is ideal.
Dirt builds up quickly on sensors given their low position and propensity for attracting dust. Frequent wiping prevents accumulation from interfering with sensor signals.
Weekly cleanings are the minimum needed to prevent significant debris buildup. But cleaning after every vacuum use is better to stop dirt in its tracks before it can cause issues.
For heavy-traffic areas needing daily vacuuming, clean sensors daily too. The small time investment needed pays off in optimally operating sensors.
What is the Proper Method to Clean Roborock Sensors?
Cleaning Roborock sensors is quick and straightforward:
- Step 1: Power off the Roborock and flip it over to access the sensors on the underside.
- Step 2: Use a dry, lint-free microfiber cloth to gently wipe clean each sensor. Apply light pressure and slowly move the cloth across the surface to dislodge and collect debris.
- Step 3: Visually inspect sensors after wiping to ensure they are completely clean and free of dirt or smudges. Re-wipe any remaining grime.
- Step 4: Repeat wiping process for all sensors, ensuring they are all clean. Roborocks have 6-10 sensors positioned around the underside perimeter.
- Step 5: Power unit back on and test sensors by having Roborock approach cliffs and drops. Verify proper sensor function and cliff detection.
Always turn the Roborock off before cleaning sensors. This prevents the vacuum from moving unexpectedly during the process.
Never use water, cleaners, or damp cloths to clean sensors. Only wipe with a dry lint-free cloth to avoid moisture damage.
Be slow and gentle during wiping to prevent scratching the delicate sensor covering. Check sensors after cleaning to confirm no residue remains.
What Cleaning Tools Work Best for Roborock Sensors?
The ideal tool for cleaning Roborock sensors is a:
- Dry microfiber cloth – The soft, lint-free material of microfiber cloths easily traps dirt, dust, and pet hair without scratching. Microfiber’s softness and electrostatic charge help collect debris.
- Coffee filter or eyeglass wipe – Both provide soft, non-abrasive lint-free surfaces good for gently wiping. The thin, disposable materials make throwing away dirt easy.
- Soft-bristle brush – For stubborn dirt, an electronics brush with soft non-metal bristles can help gently dislodge built-up debris. Ensure bristles are not abrasive.
- Compressed air – Canned compressed air can be used to blow away loose surface dirt. Keep the straw attachment nozzle 4+ inches away to avoid damaging sensors with the high-pressure air.
Avoid paper towels, tissue, or other materials leaving behind fibers or lint. Also avoid abrasive brushes or scrubbing that could scratch plastic sensor covers.
Where are the Roborock Sensors Located?
Roborock sensors are positioned around the underside perimeter of the unit. The exact quantity and layout depends on the specific Roborock model.
Most Roborocks feature 6-10 sensors placed a few inches in from the edge. They are typically black plastic discs measuring about 0.5 inches diameter. Infrared signals transmit out through the clear center.
Sensors are located under the main cover, in front of the front caster wheel, behind the rear caster wheels, and around other vulnerable perimeter areas. Their low positioning allows cliff detection.
Consult your Roborock manual for the exact sensor number and positioning for your specific unit. Sensors may be marked with small engraved “C” labels.
Can Sensors Get Damaged During Cleaning?
Yes, Roborock sensors can become damaged if cleaned improperly. The main risks include:
- Scratching plastic covers – Use of abrasive brushes or scrubbing can scratch the smooth plastic protecting the sensors. This reduces signal clarity.
- Water infiltration – Any water or liquid getting into sensors can damage internal electronics and circuitry.
- Loose components – Aggressive wiping could dislodge solder connections or internal sensor parts.
- Cracking sensor covers – Excessive pressure while wiping could crack the thin plastic covering the infrared transmitters.
To avoid these problems, only use soft dry lint-free cloths. Never submerge sensors in water. Wipe gently using light pressure to prevent dislodging components or cracking covers.
Do Third-Party Replacement Sensors Exist?
Yes, third-party companies make affordable replacement sensors for Roborock vacuums. These offer options when OEM sensors are unavailable or too pricey.
Search online marketplaces using your Roborock model number combined with “sensor” or “cliff sensor”. Compare photos to identify matching sensors.
While less costly, third-party sensors may not perfectly recreate the sensitivity and accuracy of OEM sensors. Only purchase ones with many positive reviews confirming good performance.
Installing replacement sensors involves removing the bottom cover, carefully detaching the old sensors, attaching the new set, then testing. Consult YouTube tutorials for model-specific step-by-step sensor installation guides.
What Problems Occur if Sensors Are Not Cleaned?
Failure to regularly clean Roborock sensors can lead to suboptimal performance and safety issues:
- Reduced sensitivity – Dirt blocks and weakens infrared signals, decreasing range and accuracy. Cliffs and drops may only be detected when very close.
- False cliff detection – Obscured signals can falsely detect non-existent cliffs, causing unnecessary course changes and inefficient cleaning.
- Missed cliffs – Severely dirty sensors can fail to detect cliffs at all, allowing the vacuum to fall down stairs or off ledges.
- Impact damage – Falls resulting from missed cliffs will damage the Roborock through impact. Replacement parts like sensors may be needed after such crashes.
- Ineffective cleaning – Undetected cliffs limit the vacuum’s cleaning reach since certain areas are mistakenly treated as off-limits.
Frequent and proper sensor cleaning avoids these problems and keeps Roborock vacuums operating safely and optimally.
How Does Cleaning Roborock Sensors Compare to Cleaning Other Components?
Roborock sensors require more frequent and careful cleaning versus other components:
- Filters – Washable sponge and HEPA filters only need cleaning every 1-3 months depending on use. Sensors need weekly cleaning.
- Dustbin – The dustbin just requires periodic emptying and wiping down. Sensors need special care not to get wet.
- Wheels & brush – Wheels and main brush cleanings are less frequent than weekly sensor cleaning. Their surfaces are more durable than sensors.
- Cameras – Any onboard cameras can be blown clean of dust as needed but don’t require weekly wipedowns like sensors.
Sensors are more vulnerable and require diligent cleaning care compared to other replaceable parts. Their positioning and fragile plastic covers limit cleaning methods.
Does Cleaning Sensors Drain the Battery?
Cleaning Roborock sensors does not drain the battery since the vacuum must be powered off during the process. Steps include:
- Powering off the Roborock before flipping over to access sensors. This prevents battery drain.
- Wiping sensors with a dry cloth. No power required.
- Inspecting sensors visually to confirm cleanliness. No battery impact.
- Powering the unit back on to test sensors. Brief partial drain.
- Recharging battery after testing. Returns battery to full charge.
The only minor battery drain occurs during the sensor function test. The battery can easily be topped up after cleaning and testing are complete.
Can You Use a Roborock with Dirty Sensors?
It is not advisable to run a Roborock extensively with dirty sensors. Light debris accumulation may go unnoticed. But dirty sensors risk safety issues and performance problems.
Limited use of a Roborock with somewhat dirty sensors should pose no immediate issue. But sensors require cleaning after even minimal use to prevent rapid dirt buildup.
Restrict vacuuming to open flat areas if postponing a sensor cleaning. Avoid pile rugs and cliff edges until sensors get wiped clean.
Check sensors before each use. If noticeable dirt is visible, take the few minutes needed to wipe sensors clean before vacuuming.
Does Sensor Cleaning Void the Roborock Warranty?
Cleaning sensors will not void your Roborock vacuum’s warranty, provided you follow the manufacturer’s cleaning guidelines:
- Only use a dry lint-free cloth to wipe sensors clean. Never apply water or cleaning solutions.
- Wipe gently using light pressure. Don’t attempt to scrub or scour sensors.
- Check warranty terms for any specific damage exclusions like cracked sensor covers. Damage from drops linked to uncleaned sensors would not be covered.
As long as you carefully follow the recommended cleaning procedures, there should be no warranty violations related to sensor maintenance. Improper cleaning like moisture damage would void aspects of coverage.
Can Sensors Be Cleaned Too Much?
There is little risk associated with over-cleaning Roborock sensors. The main considerations include:
- Over-scrubbing – Excessive forceful scrubbing during cleanings risks scratching plastic covers or dislodging internal parts. But gentle wiping has no downsides.
- Time expenditure – Frequent cleanings consume more time. But each cleaning only takes a few minutes, so even daily wipes will have minimal impact.
- Cost of cloths – Aggressive cleaning could require more cleaning cloths, adding minor costs. But inexpensive microfiber cloths are re-usable.
- Shortened sensor life – Theoretically, constant cleaning might wear out sensors quicker. But sensors will require replacement eventually anyway after years of use.
Unless rough scrubbing is used, cleaning sensors more often than the recommended weekly interval will not damage sensors or the Roborock vacuum. Users desiring ultra-dust-free floors may clean even more without issues.
Conclusion
Regularly cleaning infrared cliff sensors is crucial for Roborock vacuum’s effectiveness and safety. Allowing dirt buildup impedes sensor signals, limiting performance and risking severe drops.
Cleaning with a dry lint-free cloth takes just a few minutes. The small time investment provides the sizable benefits of optimally functioning sensors, expanded cleaning reach, avoidance of false cliff detection, and prevention of catastrophic falls down stairs.
By understanding proper cleaning techniques, materials, precautions, and frequency, Roborock owners can easily maintain sensors for extended vacuum lifetime and reliability. Consistently clean sensors lead to consistently clean floors.
