Cleaning Head – Flat Bottom, Right-Angle Double Shot Portafilter (53mm)

This NS300Pro Cleaning Head is precision-engineered for 53mm flat-bottom, straight-walled (right-angle) double shot portafilter baskets. Designed for compatible espresso machines with 53mm flat-base filter baskets, it features a durable full-metal body and a purpose-built rubber strip that conforms to the flat inner base of the portafilter basket. It delivers efficient, automated coffee puck residue removal with every NS300Pro cleaning cycle, helping keep your portafilter clean and ready for the next shot.

Which machines use a 53mm flat-bottom, right-angle portafilter?

This cleaning head is designed for compatible espresso machines and portafilters that use 53mm flat-bottom, straight-sided double shot baskets, including selected models from:

• Breville / Sage espresso machines equipped with compatible 53mm baskets

• De'Longhi espresso machines using compatible 53mm flat-bottom baskets

• Other espresso machines fitted with compatible 53mm flat-base precision filter baskets

• Portafilters using compatible 53mm aftermarket precision baskets

Important: Portafilter diameter and basket geometry can vary by model. Please confirm that your basket has a 53mm diameter, a flat inner base, and straight, right-angle walls before choosing this cleaning head.

Why choose the geometry-specific head over the Universal?

The 53mm flat-bottom, right-angle cleaning head is designed to provide a closer fit against the flat inner base of compatible 53mm portafilter baskets. Its purpose-built rubber strip maximizes contact with the basket surface, helping remove residual coffee grounds more thoroughly during each automated cleaning cycle.

If your espresso machine uses a compatible 53mm flat-bottom double shot portafilter basket, this geometry-specific head is the ideal choice for a more precise fit than the Universal cleaning head.

When to replace your cleaning head

• The rubber strip shows visible cracking, tearing, or deformation.

• Coffee grounds are not fully removed after a single cleaning cycle.

• The metal body becomes bent or damaged.

• The rubber strip no longer sits securely against the basket surface.
