Sweet Maria’s Aillio Bullet R1 Cleaning and Maintenance Guide
The Bullet R1 requires more frequent cleaning and careful maintenance compared to other
home roasters. If you don’t care for your Bullet R1 properly, smoke can damage the internal
electronic components that make your roaster tick. This is our recommended regimen for
keeping your Bullet R1 in tiptop shape.
After every roast
Vacuum chaff from the following locations:
Cooling box (under the bowl)
Remove cooling filter and vacuum any chaff from
the fan chamber
Around drop door
Chaff plug in rear of the machine

Every 5-10 roasts (more frequent cleaning required depending on roast level/batch size)
Remove back chaff basket
Remove the metal chaff filter and vacuum
Hold the filter up to a light source and look through
it: Can light shine through the basket? If not, soak
the basket in a solution of espresso cleaner
(Cafiza, Joe Glo, etc) for 10 minutes and gently
scrub with a brush
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.

Every 25 roasts
Remove rubber gasket, brush off the chaff
Unscrew and remove the panel covering
Vacuum chaff

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

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 - do not remove it
completely, as the screw is easy to lose
Using a metal brush, gently scrub and
vacuum any chaff/residue
Soak the fan in a solution of espresso cleaner for
10 minutes and gently scrub with a brush
(please refer to our video for a detail explanation
of impeller fan deep cleaning)

Cleaning the IBTS (V1.5/V2)
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:
● Stiff bristle (metal) brush
● Q-tips
● Rubbing alcohol
● Flashlight
Remove back cover and place in front of the drop
door to act as a stabilizer for the faceplate
Unscrew the 5 front screws to remove the
faceplate
Swivel open the faceplate and rest it on the back
cover to keep the plate stable during cleaning

Brush chaff and residue from the interior of the
plate
Locate the IBTS in the faceplate
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
