If you are roasting commercially, we recommend purchasing additional chaff baskets – that way, you can swap baskets to continue roasting without needing to pause for cleaning.
Bullet Deep Cleaning after 20-25 batches…
Disassembly and Deep cleaning of rear chaff collector
Remove rubber gasket, brush off the chaff
Unscrew and remove the panel covering
Vacuum chaff from back and clean with a brush if needed

Using a bottle brush, clean transfer tube
Brush from the front and from the rear
Vacuum any remaining chaff/residue from the front and the rear ends of the transfer tube
Rear Impeller Fan Cleaning
Clean the impeller fan by brushing and/or vacuuming any chaff/residue.
Is the impeller fan oily or coated in residue? If so, remove the fan for deeper cleaning.
Find the set screw and loosen using the #2 hex driver in the Aillio tool kit (5/64″ will also work) – do not remove it completely, as the screw is easy to lose. Just loosen it.
Using a fine metal brush, gently scrub and vacuum any chaff/residue
If need be, soak the fan in a solution of espresso cleaner for 10 minutes and gently scrub with a brush

Cleaning the IBTS (Aillio Bullet V1.5 and V2) – Infrared Bean Temperature Sensor Module
How to keep the IBTS (Infrared Bean Temperature Sensor Module) Clean and working correctly.
We recommend cleaning the sensor every 25-40 roasts – darker roasts require more frequent cleaning. If you start to see some odd changes to your temperature readings, this is an indication that the IBTS lens needs cleaning
What you’ll need:
- Soft metal bristle brush, small-ish
- Cotton Swabs / Q-tips
- Rubbing alcohol – we use 70% here but 90% is good as well.
Remove back cover and place in front of the drop door to act as a stabilizer for the faceplate.
Unscrew the 6 front screws to remove the faceplate
Swivel open the faceplate and rest it on the back cover to keep the plate stable during cleaning
Locate the IBTS in the faceplate
Brush chaff and residue from the interior of the plate
Use a flashlight to check the sensor for any oily residue or chaff
Dip a Q-tip in rubbing alcohol and gently wipe away any oils from the sensor
You’re all done! Put it back together and keep roasting!
