Breville BWM604 vs BWM620: Choose by Batch Size and Control Style

Choose the Smart Waffle 4 Slice (BWM604) when four waffle portions on its plate matter more than a display. Choose the Pro 2 Slice (BWM620) when two portions fit and you prefer its LCD countdown, waffle-style menu and twelve browning settings. The feature lists do not establish which cooks faster or makes better waffles.

The buying question

Would a four-slice plate or the Pro model's display-led control workflow better fit how you portion and set up waffles?

The BWM604 is the four-slice choice with five browning settings, a manual option and ready light; the BWM620 Pro is a two-slice model with an LCD countdown, waffle-style choices and twelve browning settings.

Quick verdict

Choose Breville Smart Waffle 4 Slice (BWM604) if

  • You want a four-slice rather than two-slice plate for each cooking cycle.
  • Five browning settings, a manual option and a ready light are enough for your control preferences.

When to skip: You need a documented plate capacity above four waffle portions in one cycle; neither listed format provides that.
When the recommendation changes
  • If your required batch is more than four waffle portions at once, neither product's documented plate format meets that requirement.
  • The published controls describe options, not a tested difference in waffle quality, cooking speed or consistency.

The differences that matter

Batch Capacity And Waffle Portion

Breville Smart Waffle 4 Slice (BWM604)

Breville identifies this model as a four-slice waffle maker.[1]

Breville Smart Waffle Pro 2 Slice (BWM620)

Two-slice waffle maker.[2]

What this changes: This is a plate-format choice: the BWM604 has room for four slices while the BWM620 plate is described for two. Slice count does not establish cooking time, serving speed or how quickly a household can eat.[1, 2]

The better fit depends on your priorities

Control And Cooking Workflow

Breville Smart Waffle 4 Slice (BWM604)

Five browning settings, a manual option and a ready light that illuminates when it is ready for batter.[1]

Breville Smart Waffle Pro 2 Slice (BWM620)

An LCD countdown and progress display, four named waffle-style settings plus Custom, twelve browning settings and an A Bit More button that adds time to a cycle.[2, 3]

What this changes: Pick by the controls you will use: a ready light and five browning choices on the BWM604, or the BWM620's screen, menu and additional settings. The number and type of controls do not show which model produces a preferable waffle.[1, 2, 3]

The better fit depends on your priorities

Limitations

  • This comparison uses Breville's published specifications and instructions; Pickoryx did not conduct hands-on or controlled side-by-side testing.
  • Slice count and control features do not establish cooking time, browning consistency, taste, reliability or real-world serving throughput.

Questions shoppers ask

Does the Pro 2 Slice make more waffles at once than the BWM604?

No. Breville describes the Pro as a two-slice maker and the BWM604 as a four-slice maker. The Pro name refers to its documented control features here, not a larger plate.

Does the LCD mean the BWM620 cooks better or faster?

Breville documents an LCD countdown and menu for the BWM620, but those specifications do not establish better results or shorter cooking time than the BWM604.
