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

Frequently Asked Questions

Which portafilter baskets are compatible with this angled-wall cleaning head?

This cleaning head is designed specifically for 58mm double-shot portafilter baskets with a flat bottom and angled or tapered inner walls. The angled-profile rubber strip follows the sloped inner walls of the basket to provide consistent surface contact during an NS300Pro cleaning cycle.

Which precision baskets can use this cleaning head?

The cleaning head is suitable for compatible flat-bottom, angled-wall baskets such as IMS Competition B70 series baskets in 18g to 22g sizes and VST precision filter baskets in 15g to 22g sizes. Compatibility should always be confirmed by checking the actual shape and diameter of your basket.

Which espresso machines can use this angled-wall cleaning head?

Compatibility depends primarily on the portafilter basket rather than the espresso machine brand. Suitable baskets may be found on selected Gaggia Classic and Gaggia Classic Pro setups, certain Bezzera and La Cimbali configurations, and La Marzocco machines fitted with compatible IMS baskets. The basket should have a 58mm diameter, flat bottom, and tapered inner walls.

Is this cleaning head compatible with all NS300Pro versions?

Yes. The Angled-Wall Soft Rubber Cleaning Head is compatible with all NS300Pro versions. Before ordering, confirm that your basket is a 58mm double-shot model with a flat base and angled or tapered inner walls.

What is the difference between the angled-wall and right-angle cleaning heads?

The angled-wall cleaning head is shaped for baskets whose inner walls taper inward toward the flat base. The flat-bottom right-angle cleaning head is intended for baskets with straight, vertical inner walls. Choosing the correct profile helps the rubber cleaning strip maintain better contact with the basket surface during cleaning.

How can I tell if my basket needs the angled-wall cleaning head?

Look inside your 58mm portafilter basket and check the side walls. If the basket has a flat bottom and the inner walls slope or taper inward as they approach the base, this angled-wall cleaning head is the appropriate profile. If the walls remain completely vertical, a right-angle cleaning head is more suitable.

When should I replace the angled-wall cleaning head?

Replace the cleaning head when the rubber strip becomes cracked, torn, damaged, or no longer follows the angled basket profile. Replacement may also be required if coffee grounds are no longer fully cleared during a complete automated cleaning cycle or if the metal body becomes bent or deformed.

What is included with the Angled-Wall Soft Rubber Cleaning Head?

The package includes one full-metal cleaning head fitted with an angled-profile rubber cleaning strip. It is designed specifically for 58mm double-shot portafilter baskets with a flat bottom and tapered inner walls.
