1. The Missing Boiler Capacity (The Most Critical Spec)
The Problem: You have listed the physical weight ($72\text{ kg}$) and the power ($3000\text{W}$), but you completely omitted the Boiler Capacity. In commercial espresso machines, boiler volume is everything—it determines how much steam and hot water the barista has before the machine runs out of pressure.
The Fix: A double-group commercial machine of this weight typically houses a 10L to 14L boiler. You should absolutely add a line for Boiler Capacity: 11L (or whatever its true size is).
2. Power vs. Weight Recovery Reality
The Nuance: A $72\text{ kg}$ machine is a heavy, full-sized commercial workhorse. Matching a massive boiler inside a 72 kg chassis with only a $3000\text{W}$ heating element means the machine might have a relatively slow thermal recovery time during a heavy morning rush. While $3000\text{W}$ works perfectly fine for a compact or entry-level 2-group, high-volume full-sized commercial units usually sit closer to $3500\text{W}\text{ to }4500\text{W}$.
The Fix: Double-check the heating element wattage. If it's truly $3000\text{W}$, it's worth highlighting this in the features as an "Eco-conscious, energy-saving power draw that runs on a standard 15-amp commercial circuit." If it's actually a high-volume machine, the wattage might be closer to $4000\text{W}$.
3. Missing Water Supply & Drainage Info
The Problem: Commercial kitchens need to know how to plumb an appliance before they buy it. The sheet doesn't specify how the machine gets its water.
The Fix: Add a line for Water Connection and Drainage. For a machine this size, it should read:
Water Inlet: Direct mains water line connection (usually 3/8" copper or braided hose)
Drainage: Direct waste water drain connection
4. Clarify "Manual Key Operation"
The Nuance: In the coffee industry, "manual key" usually means either a mechanical lever or a simple start/stop button where the barista has to press the button a second time to stop the shot (a "Semi-Automatic" machine). If the machine automatically stops the shot at a programmed volume, it is an "Automatic" (or Volumetric) machine.
The Fix: Update the Control spec to industry-standard terms: Semi-Automatic (Manual Start/Stop Keys) or Volumetric Automatic (Programmable Dosing) so buyers know exactly how the workflow feels.
