What customers like about Polti S15W

  • The 19 bar pump pushes water hard through the coffee for a strong cup.
  • Adjustable coffee temperature lets you choose how hot the drink is.
  • ESE pods are ready portioned, so there is no scooping.
  • The removable water tank comes out for filling.
  • Automatic shutdown and overheat protection keep it safe when left on.
  • Sleep mode saves power between cups.

What customers don't like about Polti S15W

  • The 0.85 L tank is small for several cups in a row.
  • There is no display to show settings or status.
  • There is no capsule support, so ESE pods are the only pod option.
  • The cup height is fixed, so tall glasses may not fit under the spout.
  • There is no milk frother, so milk drinks need a separate jug.

Verdict

Built for one or two cups at a time, the Polti S15W suits a small household more than a busy kitchen. Its 19 bar pump gives a strong cup, and the 1400 W heater gets the water hot quickly. The adjustable coffee temperature lets you set how hot each cup comes out, and ESE pods are ready portioned, so there is no scooping. The removable water tank comes out for filling, and automatic shutdown and overheat protection keep the machine safe when you leave it. The 0.85 L tank is the limit, since it needs refilling quickly when several people want a cup in a row. It suits one person who wants a strong cup in the morning and does not need milk drinks, a display or an app.
