Clean your Shark robot vacuum weekly to keep it running smoothly
A Shark robot vacuum works best when its sensors, brushes, and dustbin stay clean. Dust and pet hair clog the suction path and jam the side brush, which cuts cleaning power in half. Weekly cleaning takes about five minutes and prevents the vacuum from getting stuck or losing suction.
The good news: you do not need special tools or replacement parts to do basic maintenance. A dry cloth, an old toothbrush, and scissors are enough for most jobs. Start with the dustbin, then move to the brushes and sensors—in that order, because the dustbin collects the most debris.
Key Takeaways
- Empty the dustbin after every run and wipe the filter with a dry cloth to restore suction.
- Remove the side brush and main brush weekly, cut away tangled hair with scissors, and rinse them under water if they smell.
- Clean the cliff sensors and camera lens with a dry cloth every two weeks so the vacuum does not get confused about stairs or obstacles.
- Check the wheels and undercarriage monthly for matted hair or debris that can slow the vacuum down or cause it to stop moving.
Empty and rinse the dustbin after each cleaning cycle
The dustbin is where most of the work happens. After the vacuum finishes, press the release button on the back of the unit and pull the bin straight out. Tap it over a trash can to shake out loose dirt and hair, then wipe the inside walls with a dry cloth or paper towel.
Next, locate the filter—a foam or pleated cartridge inside the bin. Tap it gently over the trash to dislodge dust, then wipe it with a dry cloth. Do not rinse the filter with water unless the manual says it is washable; most Shark filters are not. If the filter smells stale or musty after a few weeks, you can rinse it under cool running water and let it air-dry completely (at least two hours) before putting it back.
Slide the clean bin back into the vacuum until you hear it click. A clogged dustbin is the number-one reason a Shark loses suction, so this step matters more than anything else.
Remove and clean the side brush and main brush
The side brush is the small spinning brush on the right side of the vacuum. Press the release tab or unscrew the brush holder (depending on your model) and pull the brush out. Hair wraps around the bristles in a spiral, so use scissors to cut it away. Work slowly and cut parallel to the bristles so you do not accidentally trim them short.
The main brush sits underneath the vacuum, running front to back. Flip the vacuum over and locate the brush cover—usually held by two clips or screws. Open it and slide the brush out. Again, cut away any tangled hair with scissors. If the brush smells bad or feels sticky, rinse it under cool water and shake it dry.
Wipe both brushes with a dry cloth before reinstalling them. Put them back in the same way you removed them, and make sure they spin freely by hand before you turn the vacuum on. A stuck brush will not spin and can burn out the motor.
Wipe sensors and the camera lens every two weeks
Shark robot vacuums use cliff sensors on the underside to detect stairs and a camera or laser on top to map your home. Dust on these parts makes the vacuum confused—it may think there is a cliff where there is not, or it may bump into furniture instead of going around it.
Flip the vacuum over and look for small black or clear circles on the bottom. These are the cliff sensors. Wipe each one gently with a dry cloth. On top of the unit, find the camera or laser dome (a clear or dark bump in the center). Wipe that too with a dry cloth. Do not use water or cleaning spray—dry cloth only.
Clear hair and debris from the wheels and undercarriage
The wheels pick up hair and lint as the vacuum moves, which slows it down or stops it from moving at all. Flip the vacuum over and look at the two large wheels on the sides. Use your fingers or a cloth to pull away any matted hair or string wrapped around the axle. Wipe the wheel itself clean.
While you are underneath, check the front caster wheel (the small wheel in the middle). Spin it by hand to make sure it rolls freely. If it is stuck, pull away any hair and wipe it clean. Also look at the undercarriage for any large clumps of dirt or debris and pull them out by hand.
Check the charging contacts monthly
The charging contacts are the metal strips on the back of the vacuum and on the dock. Over time, dust settles on them and the vacuum will not charge properly. Once a month, wipe both sets of contacts with a dry cloth. If they look dark or corroded, dampen the cloth slightly with water and wipe again, then dry when ready with a clean cloth.
Make sure the dock itself is on a hard, level surface away from walls or furniture. The vacuum needs a clear path to back into the dock, so keep the area in front of it clear.
Replace the filter and brushes when they wear out
Filters and brushes do wear out and eventually stop working even after cleaning. Most Shark filters last two to three months with regular use; brushes last four to six months. You will notice suction dropping even after you clean the bin, or the brushes will look matted and worn instead of bristly.
When that happens, order replacement parts from Shark's website or from a retailer that sells Shark vacuums. Installation is straightforward—just slide the old part out and the new one in. Keep a spare filter and brush set on hand so you do not have to wait for a delivery when one wears out.
Frequently Asked Questions
How often should I clean my Shark robot vacuum?
Empty the dustbin and wipe the filter after every cleaning run. Clean the brushes and side brush weekly. Wipe the sensors every two weeks. Check the wheels and undercarriage monthly. This routine keeps the vacuum running at full power and prevents jams.
Can I use water to clean the brushes?
Yes, you can rinse the brushes under cool running water if they smell bad or feel sticky. Let them air-dry completely (at least two hours) before putting them back in the vacuum. Do not use hot water or soap. Never soak the brushes or submerge the motor housing.
What does it mean if the vacuum loses suction after cleaning?
A clogged dustbin or filter is the most common cause. Empty the bin and wipe the filter first. If suction is still weak, check the main brush and side brush for tangled hair, and make sure the cliff sensors are not blocked by dust. If none of that works, the filter may need replacement.
Why is my Shark vacuum not moving?
Hair wrapped around the wheels or axles is usually the culprit. Flip the vacuum over and pull away any matted hair from both large wheels and the front caster wheel. Spin each wheel by hand to make sure it moves freely. If the wheels are clean and still stuck, the motor may need service.
Do I need to replace the filter if I rinse it?
Rinsing the filter extends its life, but it will eventually wear out. Most filters last two to three months with regular use and weekly rinsing. When suction drops even after cleaning and rinsing, it is time to order a replacement. Shark sells filters as individual parts or in multi-packs.
