Compatibility is a decision, not a diameter guess.

Breville the Bambino
BES450
Unknown

Bottomless Portafilter is documented for a different nominal size or product family than the Bambino, but the cited sources do not publish the complete locking lugs, lug angles, insertion depth, and group-head profile needed to prove fit or incompatibility. Caffeware therefore leaves this pair Unknown.

Evidence: conflict. A family label or diameter difference is not treated as complete, category-specific physical-interface evidence.
Breville the Bambino Plus
BES500
Unknown

Bottomless Portafilter is documented for a different nominal size or product family than the Bambino Plus, but the cited sources do not publish the complete locking lugs, lug angles, insertion depth, and group-head profile needed to prove fit or incompatibility. Caffeware therefore leaves this pair Unknown.

Evidence: conflict. A family label or diameter difference is not treated as complete, category-specific physical-interface evidence.
Breville the Barista Express
BES870XL
Unknown

Bottomless Portafilter is documented for a different nominal size or product family than the Barista Express, but the cited sources do not publish the complete locking lugs, lug angles, insertion depth, and group-head profile needed to prove fit or incompatibility. Caffeware therefore leaves this pair Unknown.

Evidence: conflict. A family label or diameter difference is not treated as complete, category-specific physical-interface evidence.
De’Longhi Dedica Arte
EC885M
Unknown

Dedica Arte's exact US sources do not publish the critical nominal brew-group or filter dimension required to evaluate Bottomless Portafilter. Caffeware therefore leaves this pair Unknown.

Evidence: conflict. Missing exact-model machine dimension; no family or cross-model inference is permitted.
Gaggia Classic Pro E24
RI9380 (SIN035R)
Unknown

Bottomless Portafilter and the Classic Pro E24 are both documented at a nominal 58 mm, but the accessory page does not name the E24 or publish complete locking-lug and installed-depth geometry. Caffeware therefore leaves this pair Unknown.

Evidence: conflict. Matching diameter alone is not treated as exact portafilter fit evidence.
