Cleaning Head – Flat Bottom, Angled-Wall Double Shot Portafilter (58mm)
This NS300Pro Cleaning Head is engineered for 58mm portafilter baskets with a flat bottom and angled (tapered) inner walls — a geometry found on precision aftermarket baskets and select specialty espresso machines. The full metal body paired with a purpose-built angled rubber strip creates flush, full-contact cleaning against the sloped inner wall surface, ensuring thorough coffee puck residue removal on every automated NS300Pro cleaning cycle.
Which baskets and machines use a flat-bottom, angled-wall profile?
This is the geometry of choice for specialty coffee professionals and serious home baristas using precision filter baskets, including:
-
IMS Competition baskets (B70 series, 18g–22g) — widely used in specialty cafés and competitions
-
VST precision filter baskets (15g–22g) — the industry standard for competition-grade extractions
-
Select Gaggia Classic and Gaggia Classic Pro stock baskets
-
Certain Bezzera and La Cimbali precision aftermarket baskets
- La Marzocco machines fitted with IMS-supplied baskets
Flat-bottom angled vs flat-bottom right-angle — what's the difference?
The right-angle cleaning head (sold separately) is designed for baskets with perfectly vertical inner walls. This angled-wall head is shaped for baskets whose inner walls taper inward toward the base — providing a more precise rubber-to-surface contact on these specialist geometries. If you're unsure which you need, check whether your basket walls are vertical or slightly tapered.
When to replace your cleaning head:
-
The rubber strip is cracked, torn, or no longer follows the angled profile
-
Coffee grounds are not fully cleared in a single automated cycle
- The metal body is bent or deformed
