You should service the HEPA filter regularly to keep its performance at the same level.
We recommend cleaning the filter once a month.
To do this, you just have to remove the filter and carefully tap it out over a dustbin.
Removing the HEPA filter
HEPA filter cleaning
You should also remove dust from the HEPA filter with the included cleaning brush (or a toothbrush).
Depending on the manufacturer and filter type, you can sometimes even wash the HEPA filter under running water.
Read the instructions to see whether you can clean the filter with water or not. We strongly recommend that you follow the manufacturer's instructions.
When you clean the filter (especially when you tap it out), you’ll also stir up the aggressive house dust. That’s far from pleasant for a person with severe allergies.
Therefore, we have 3 tips on how to reduce allergen exposure during the cleaning process.
Tip 1: Wear a mask when cleaning (uncomplicated method)
Everyone knows and owns it these days: the mask.
Therefore, we recommend putting on a respiratory mask when cleaning (especially when tapping out) the filter.
This way, you won’t inhale the allergens and prevent an allergic reaction.
Tip 2: Cleaning the HEPA filter outdoors
If you have a garden or balcony, we recommend cleaning the HEPA filter outdoors.
Many allergens get into the air during the process, especially when tapping out the filter.
Outside, the dust particles will be distributed in a much larger volume of air. Thus, you’ll also inhale only a smaller amount of dust particles.
If you wear a mask, too, you’ll have additional protection.
Tip 3: Tap out HEPA filter in a plastic bag
If you don’t like the first two options, we have another - slightly more complicated - cleaning method.
You’ll have to do the following steps:
- Lightly moisten a kitchen wipe,
- Put the wipe in a plastic bag and place the HEPA filter on top,
- Tap out the HEPA filter in the closed plastic bag,
- After tapping out the HEPA filter, leave it in the bag for a few minutes (until the dust settles),
- Then take out the filter, carefully close the plastic bag and throw it away.
With this method, you prevent most allergens from getting back into the air or your airways.
Regular filter change is mandatory
No matter how carefully you clean the HEPA filter...
...you should still replace it at regular intervals.
Depending on the degree of contamination, you should change the filter every 3-6 months (heavy contamination) or 7-12 months (light contamination).
You can usually order replacement filters conveniently on the Internet.
Maintenance of the brush roll
If you are a pet owner (or even people with long hair), you know this too well.
You can often find pet hair and also long human hair on the floor.
These can wrap around the brush roll (and also the side brush).
You should clean the brushes from time to time, as these often cause allergic reactions.
Even if you don’t have pets or people with long hair in the household, some dirt still accumulates in the brushes, so you should remove that regularly.
You can remove, disassemble and clean the main brush in no time.
Many manufacturers include a unique cleaning tool in the delivery scope for cleaning. With this, you can easily remove the stuck hairs.
You could also use conventional scissors.
Replacing the brush regularly
If the bristles protrude in all directions and the cleaning performance decreases a lot, you should replace the brushes.
People with severe allergies should always check if the robotic vacuum cleaner provides optimal cleaning performance.
A useful feature: the app indicates when you should replace the brushes.
You should take this information as a guideline. Depending on the use of the robot vacuum, the brushes may last much longer.
You can buy the spare parts at amazon, too.
If you chose a robot vacuum with a mopping function, you also have to clean the mop regularly.
...because it usually looks like this when it finished mopping your flat:
We recommend washing the mop with your dirty laundry in the washing machine at 40 degrees after each cleaning trip.
You should buy several replacement wipes so that you always have a clean wipe at hand. You can order these online, too (on Amazon UK).
