How to Replace and Maintain SwitchBot S Series Vacuum Filters for Peak Performance

Quick Answer

For peak performance, replace your SwitchBot S Series dustbin filter every 1-2 months and clean it weekly. Use the S Series Replacement Kit for 1 year use to get genuine parts that fit perfectly, and always check the main brush and waste water parts for wear during each filter change.

Your SwitchBot S Series robot vacuum works hard to keep your floors clean, but its filters and brushes don't last forever. Over time, dust and debris clog the dustbin filter, reducing suction and leaving your home less clean. Regular maintenance is the key to keeping your vacuum running efficiently and extending its lifespan.

In this guide, we'll walk you through the steps to replace and maintain your S Series vacuum filters, including the dustbin filter, main brush, and waste water parts. You'll learn what to check, how often to replace each component, and common mistakes to avoid—so your vacuum keeps performing at its best.

What's in the SwitchBot S Series Replacement Kit?

The SwitchBot S Series Replacement Kit for 1 year use includes everything you need for a year of maintenance: Side Brush × 2, Main Brush × 1, Dustbin Filter × 4, Roller Mop × 2, Waste Water Parts × 1, and Dust Bag Pack × 5. This kit is designed to keep your S Series vacuum in top shape without hunting for individual parts.

Having these genuine parts on hand means you can replace filters and brushes as soon as they show signs of wear, rather than waiting for a delivery. This proactive approach ensures your vacuum never loses suction or cleaning efficiency due to a clogged filter or worn brush.

• Check the kit contents against your model's manual to confirm compatibility.
• Store the kit in a cool, dry place to keep filters and brushes in good condition until needed.

When to Replace the Dustbin Filter

The dustbin filter is your vacuum's first line of defense against dust and allergens. Over time, it becomes clogged with fine particles, reducing airflow and suction power. For best performance, clean the filter every 1-2 weeks and replace it every 1-2 months, depending on usage and pet hair levels.

Signs that it's time to replace the filter include a noticeable drop in suction, visible damage or tears, or a persistent musty odor. Using a clogged or damaged filter can also strain the motor, so don't ignore these warning signs.

• Set a monthly reminder to check the filter condition.
• If you have pets, consider replacing the filter more frequently.

How to Clean the Dustbin Filter

Cleaning the dustbin filter is quick and easy. Remove the dustbin from the vacuum, take out the filter, and gently tap it against a trash bin to dislodge loose dust. For a deeper clean, rinse the filter under lukewarm water (if your model allows it) and let it air dry completely before reinstalling.

Never use a washing machine or dryer, and avoid scrubbing the filter with harsh brushes—this can damage the delicate fibers. Always ensure the filter is completely dry before putting it back, as moisture can cause mold and reduce filtration efficiency.

• Clean the filter outdoors or over a bin to avoid spreading dust indoors.
• Replace the filter if it remains discolored or doesn't rinse clean.

Checking and Replacing the Main Brush

The main brush is responsible for agitating dirt and debris from your floors so the vacuum can suck it up. Over time, hair and strings can wrap around the brush, reducing its effectiveness. Check the main brush every two weeks and remove any tangles using the cleaning tool or scissors.

Replace the main brush when the bristles are visibly worn, bent, or missing. A worn brush not only cleans poorly but can also scratch hard floors. The S Series Replacement Kit includes a new main brush, so you'll have one ready when needed.

• Inspect the brush for wear at least once a month.
• Use a seam ripper or scissors to carefully cut away tangled hair.

Maintaining Waste Water Parts (For Combo Models)

If your S Series model includes mopping functionality, the waste water parts are essential for keeping the mopping system hygienic. These parts collect dirty water from the mop and should be cleaned regularly to prevent odors and bacterial growth.

After each mopping session, empty and rinse the waste water tank. Check the waste water parts for clogs or damage, and replace them as needed—the S Series Replacement Kit includes one set. Keeping these parts clean ensures your mop leaves floors fresh, not musty.

• Rinse the waste water tank with clean water after every use.
• Replace the waste water parts if you notice leaks or reduced water flow.

Step-by-Step: Replacing Your S Series Dustbin Filter

1. Remove the dustbin: Press the release button on the dustbin and pull it out of the vacuum. Empty any debris into a trash bin. Checkpoint: Ensure the dustbin is completely empty before proceeding.
2. Take out the old filter: Locate the filter compartment and carefully remove the old filter. Note how it sits so you can insert the new one correctly. Common mistake: Don't force the filter out—if it's stuck, check for debris blocking it.
3. Install the new filter: Insert the new dustbin filter from the S Series Replacement Kit, ensuring it fits snugly and securely. Make sure it's fully seated to prevent air leaks. Checkpoint: The filter should sit flush with no gaps around the edges.
4. Reattach the dustbin: Slide the dustbin back into the vacuum until it clicks into place. Double-check that it's locked securely. Common mistake: If the dustbin isn't locked, the vacuum may not operate correctly.
5. Run a test cycle: Turn on the vacuum and run a short cleaning cycle to confirm everything works. Listen for unusual noises and check for proper suction. Verdict: If suction seems weak, recheck the filter installation.
