Choose the CMM01A if you want a non-electric manual lever machine and are comfortable supplying hot water and managing preheating. Choose the CMM01B if you want built-in PID temperature control while keeping hands-on lever extraction. Both are listed with a 58mm brewing structure and manual pressure control. Your heating routine is the most useful starting point for choosing between them.
This ITOP guide explains the buying decision using current product information, official demonstrations and clearly attributed owner discussions. ITOP supplies both models. The community experiences below are individual reports, rather than tests performed by ITOP.
Choose your heating routine
Supply hot water separately and follow the preheating instructions.
No plug is required for the machine itself.
Built-in PID temperature control.
Confirm the electrical version and plug for your destination.
Both models require manual coffee preparation and lever operation.
| Buying consideration | CMM01A | CMM01B |
|---|---|---|
| Heating arrangement | Non-electric; supply hot water separately and follow the preheating instructions | Built-in PID temperature control |
| Electrical planning | No plug required for the machine itself; plan how to heat water | Confirm the ordered voltage and plug against your local supply |
| Brewing structure | Listed as 58mm; check individual accessory fit | Listed as 58mm; check individual accessory fit |
| Pressure control | Manual; published range 1–16 bar | Manual; published range 1–16 bar |
| Main tradeoff | You manage a separate hot-water and preheating routine | You need electrical compatibility and still prepare and pull each shot manually |
| Price and delivered cost | Request a current quote for the configuration, quantity and destination | Request a current quote for the electrical version, configuration, quantity and destination |
Check the current CMM01A product information and CMM01B product information before ordering. The pressure range describes the published control range; the top of that range is not a recommended brewing target. Use the operating instructions supplied for your exact machine.
For CMM01B, use the voltage and plug guide to prepare the supply and connection details to confirm before ordering.
The official CMM01B demonstration introduces the machine and follows a preparation and extraction sequence. These links point to relevant sections identified in its English transcript:
Use the video to understand the sequence and questions to ask. A temperature setting or a display reading does not by itself establish the temperature at the coffee or repeat-shot temperature stability. Ask for the measurement location, method and conditions when comparing temperature claims.
Our guide to boilers, thermoblocks and PID explains why the heating arrangement, sensor location and control method need to be considered together.
The official two-generation comparison includes the non-electric preparation demonstration from about 1:37 and introduces the PID version from about 4:25. Confirm that the configuration shown matches the version in your quote, especially when watching an older video.
What to check in a demonstration
A single extraction does not establish continuous commercial capacity.
In a CMM01A owner discussion on r/espresso, the author describes approximately three weeks of ownership. The report discusses preheating, initial assembly, pressure-gauge sealing and movement while operating the lever. These are useful commissioning questions: ask for the current assembly instructions, the correct setup surface and support if something needs adjustment. Follow the supplied instructions and contact support for leaks or assembly issues.
The CMM01B first-impressions report, published on May 21, 2026, appears on Reddit and in the Home-Barista CMM01B discussion. The opening posts are by the same contributor, Internally_Combusted, and describe the same purchase. They represent one owner's initial experience across two forums.
The Reddit report values the heated-water workflow and also describes learning the inlet-valve action and managing the drip area. A later Reddit reply says temperature stability was not independently checked with probes. Ask to see filling, priming and cleanup on the offered version, and distinguish display observations from measured performance.
Each thread concerns an individual's machine and routine. They help identify what to check before purchase; they do not establish how frequently an issue occurs or how every unit will perform.
Plan the grinder, basket, tamper, scale, cups and work surface together. A 58mm label is a starting point for compatibility checks: confirm basket dimensions, portafilter fit and cup clearance for the actual accessories you intend to use.
The CMM01B video discusses portafilter options, and the supplied image shows one example configuration. Ask which portafilter, basket, seals, drainage components and instructions are included in your order. ITOP confirms that DM2 is the manual model designation for CMM01B. Request the applicable manual revision and parts references for the electrical version and configuration being supplied. A video option or an item in a photograph should be checked against the agreed packing list.
When asking about a replacement part, provide the machine's model and version, a photograph of the relevant part and its reference from the applicable documentation. This helps the team check the required part before quoting. A component overview is not a disassembly or electrical-service instruction.
For milk drinks, confirm the separate milk-heating or steaming equipment your setup requires. If you also need a grinder, read the CGFL250 controls and buying checks.
For a home coffee bar: shortlist CMM01A when a separate hot-water routine fits the way you make coffee. Shortlist CMM01B when integrated heating better suits your work surface and preparation routine. Compare the full setup cost, available space, cleaning steps and the amount of manual preparation you want.
For a studio, training bench or business: describe the actual use before choosing. Ask for a demonstration covering consecutive drinks, replenishment, cleanup and the recommended workload. Peak demand, staffing and milk service affect suitability. A single extraction or an owner's positive report does not establish continuous high-volume café capacity.
For distribution or OEM/ODM enquiries, ask about the offered configuration, samples, spare parts, documentation and available customization. Have ITOP confirm MOQ, lead time, certification applicability and warranty terms for the particular model, market and order.
For a personal enquiry, provide the model, intended drinks, existing grinder, destination country and electrical requirements where applicable. For business or distribution enquiries, also provide quantity, expected use, peak demand and customization requirements.
