Question 1

Does the Wendougee LITA SIGMA ship to the EU and EEA?

Accepted Answer

Yes. Vellutto ships the Wendougee LITA SIGMA across the EU and EEA with insured carriers. Handling is 1–2 business days, transit 2–7 business days depending on destination.

Question 2

What is the Wendougee LITA Sigma?

Accepted Answer

The LITA Sigma (Sigma-Σ) is a single-group, semi-automatic home espresso machine and the most expressive machine in Wendougee's SMART home line. It builds on the compact dual-boiler LITA platform but replaces the pump with a commercial-grade gear pump and adds a physical electronic flow paddle on the group head for real-time, hands-on flow control.

Question 3

How is the LITA Sigma different from the LITA BA and LITA LA?

Accepted Answer

The LITA BA and LA control pressure and flow through Wendougee's touch disc and the E-Bar app, driven by twin electromagnetic vibratory pumps. The Sigma changes the hardware itself: it uses a quieter commercial gear pump (the same architecture as Wendougee's flagship Data S) and adds a tactile flow paddle, so you shape the shot by feel in real time rather than only through the app.

Question 4

What is the electronic flow paddle and what does it do?

Accepted Answer

The paddle is a physical lever on the group that gives you direct command of flow during the shot. You can open gently for a long, soft pre-infusion, ramp into peak pressure for body, then taper the finish to control astringency — all by hand, mid-extraction, with no menus. It's the same philosophy as lever-style flow control on machines like the Lelit Bianca, applied to Wendougee's gear-pump system.

Question 5

Does the Sigma have a dual boiler?

Accepted Answer

Yes. The Sigma uses Wendougee's saturated dual-boiler LITA architecture, with independent brew and steam circuits so you can pull a shot and steam milk at the same time, with PID-managed temperature stability.

Question 6

What pump does the Wendougee Sigma use?

Accepted Answer

A commercial-grade gear pump — the same type used in Wendougee's top-tier Data S. Compared with the vibratory pumps in the standard LITA, a gear pump runs noticeably quieter and gives smoother, more linear control over pressure and flow, which is what makes true profiling possible.

Question 7

Can I connect the Sigma to an app?

Accepted Answer

Yes. The Sigma works with the Wendougee E-Bar app and is compatible with a Bluetooth scale (sold separately), so you can save recipes and review pressure and flow curves. The app is optional — the Sigma works fully as a tactile lever machine on its own.

Question 8

What size portafilter does the Sigma use?

Accepted Answer

The Sigma is built on the LITA platform, which uses a standard 58 mm portafilter with a 316 stainless saturated group head. This is provisional pending Wendougee's final Sigma specification sheet, but 58 mm is the established LITA-platform size and the industry-standard prosumer fitting, same as La Marazocco machines

Question 9

What are the full specifications of the LITA Sigma?

Accepted Answer

Confirmed for the Sigma: single-group semi-automatic, commercial gear pump, electronic flow paddle, dual boiler, E-Bar app and Bluetooth scale compatibility. Carried over from the LITA BA/LA platform (provisional until Wendougee publishes the Sigma's official sheet): roughly a 0.35 L brew boiler plus 0.8 L steam boiler, 0–9 bar at ±0.1 bar, PID on both boilers, ~1.2 L removable tank, 240 V / ~2,100 W, approximately 26 × 38.6 × 33.4 cm and ~22 kg. We update this page as Wendougee confirms final figures.

Question 10

Is the LITA Sigma plumbed in or tank-fed?

Accepted Answer

The LITA platform the Sigma is based on is tank-fed with a removable reservoir of around 1.2 L. Plumb-in capability has not been confirmed for the Sigma. We'll update this page once Wendougee specifies it.

Question 11

What colours or finishes is the Sigma available in?

Accepted Answer

Finish options have not yet been confirmed by Wendougee for the Sigma. We will list available finishes on this page as soon as they're released.

Question 12

How does the Sigma compare to the Lelit Bianca, Profitec, or La Marzocco Linea Mini?

Accepted Answer

The Sigma is aimed at the home barista cross-shopping machines like the Lelit Bianca V3, Profitec Pro 600, La Marzocco Linea Mini R or Arkel Coast — people who want commercial pump hardware and lever-driven flow control without a commercial footprint or price tag. Its distinguishing combination is a commercial gear pump paired with a physical flow paddle on a compact dual-boiler chassis.

Question 13

Who is the Wendougee LITA Sigma for?

Accepted Answer

It's for the home barista who has outgrown push-button espresso and wants to actively shape each shot. If you want tactile, real-time flow control, dual-boiler stability, and the option of app-based recipe profiling in a counter-friendly footprint, the Sigma is built for you.

Question 14

Can I order the Sigma now and ship it within the EU?

Accepted Answer

Yes. The LITA Sigma is should be available to pre-order through Vellutto soon and for delivery across the EU/EEA. Because it's a build-to-order machine from a limited early production run, please expect a lead time of several months. Confirmed specifications and shipping estimates are updated on this page as Wendougee releases them.

Question 15

Which mode should I use pressure profiling or flow priority?

Accepted Answer

Honestly, it depends on the coffee and what you're chasing in the cup.  Pressure profiling is the intuitive choice if you've used a lever machine — you think in pressure phases, and that's what the curves look like. Flow profiling is often easier to dial in, because the pump quietly corrects for small grind inconsistencies that would otherwise throw off a pressure-based shot.

Question 16

How long does the Wendougee LITA take to heat up?

Accepted Answer

Less then 10 minutes from cold to brew-ready, which is faster than most E61 machines. For best consistency, let it sit a couple of minutes longer after it hits temperature so the group head and portafilter fully stabilise before your first shot.

Question 17

Can I share espresso profiles with other Wendougee LITA users?

Accepted Answer

Yes. The Wendougee E-bar app includes a Community tab where users upload and download profiles, so beginners can pull up recipes from experienced baristas instead of dialling everything in from zero.  One thing to be realistic about: downloading a profile won't give you someone else's exact shot. Grinder, beans, water, and ambient conditions all push the result around, so a shared profile is a head start you'll still need to tweak the grind and probably adjust a few parameters to make it sing on your setup.

Question 18

Can the Wendougee LITA stop extraction by weight using a scale?

Accepted Answer

Yes. The LITA pairs with an external scale like BooKoo scale over Bluetooth and cuts the shot automatically when it reaches your target weight no watching the scale and reaching for the paddle.  Supported scales right now:  BooKoo Acaia (not yet)

Question 19

Can the Wendougee LITA firmware be updated?

Accepted Answer

Yes. The Wendougee E-bar app gets regular updates that add new features, and machine firmware is flashed through the same app — you don't need cables or a service visit.  Follow the manufacturer's instructions when an update runs. Don't unplug the machine or close the app partway through, or you risk bricking the firmware.

Question 20

What problems does the Wendougee LITA solve, and why choose it?

Accepted Answer

Most of the LITA features map directly to specific frustrations home baristas run into. Here's how it handles them:  Inconsistent shots. The gear pump holds pressure steadily with real-time feedback, so shot-to-shot variation drops and your profiles actually become reproducible instead of lucky.  Not enough control over extraction. Choose pressure profiling or flow profiling, adjust the pump in fine increments, and build whatever curve you want pre-infusion ramps, pressure plateaus, declining tails. Every profile saves in the E-bar app and recalls with a tap.  The learning curve on manual machines. The E-bar app shows live pressure, flow, and temperature graphs while you pull, and lets you save what worked. Pair it with the MILO II grinder and Themis scale and you get a guided dial-in workflow that walks you through the process step by step.  Temperature swings. Two independent stainless-steel boilers, each with its own PID controller, handle brew and steam separately. Stability is on par with commercial machines.  Slow warm-up. About five minutes from cold to brew-ready — faster than most E61 machines in this category.  Loud, uneven pumps. The gear pump is much quieter than a vibration pump and gives smoother pressure transitions. In sound and feel, it's closer to a rotary.

Question 21

Do I need a tablet to use the LITA?

Accepted Answer

No — after a one-time setup with the free E-Bar app on any Android or iOS phone/tablet, the LITA runs standalone. Saved profiles load onto the Intelligent Disc and launch from there. Many owners report using the app only occasionally to dial in a new coffee.

Question 22

Is the Wendougee Sigma a good machine?

Accepted Answer

The Sigma is built on the well-regarded LITA dual-boiler platform, which has drawn praise for shot quality, build quality, quiet operation and steam power, combined with the gear pump from Wendougee's flagship Data S and a flow paddle for hands-on control. As a newly launched machine, independent hands-on reviews are still emerging; we'll add review content to this page as it becomes available.

Question 23

Does the LITA SIMGA do pressure profiling AND flow profiling?

Accepted Answer

Yes — but one at a time per profile. Each profile is either pressure-priority (you programe the bar curve and flow adapts) or flow-priority (you programe the ml/s curve and pressure adapts), with a needle valve capping maximum flow at 12 ml/s. You only can mix them when you design a profile.

Question 24

Which grinder and scale pair with the LITA SIGMA over Bluetooth?

Accepted Answer

Wendougee's own MILO Play and MILO II grinders pair through the E-Bar app, and BOOKOO's Themis Mini and Themis Ultra scales pair for stop-by-weight shots. Acaia Lunar is on the roadmap but is not currently supported. Third-party grinders work perfectly as dumb grinders; only the E-Bar ecosystem talks to the app.

Question 25

How do I pull a shot by weight with a BOOKOO Themis?

Accepted Answer

Pair the Themis to the E-Bar app over Bluetooth, set a target yield (say 36 g) in the profile, tare with the empty cup on the drip tray, then push the play button. The machine cuts the pump automatically when the scale reports target weight.

Question 26

Can I share or import profiles from other users?

Accepted Answer

The E-Bar app supports recipe download and saving of pre-configured flavour curves, based on the Grokipedia/app-store documentation of the Wendougee platform. Cross-user sharing works via profile files. The community is smaller than Decent's Diaspora, so profile libraries are still improving.

Question 27

How loud is the LITA SIGMA?

Accepted Answer

Gear Pumps are quieter than a classic Ulka, it is the same as the DATA S gear pump.

Question 28

LITA SIGMA vs La Marzocco Linea Mini / Micra?

Accepted Answer

Linea Mini uses a saturated group, paddle pre-infusion, and commercial pedigree, at roughly double the LITA SIGMA's price. The Micra vs LITA direct shortlist. The LITA SIGMA matches Micra on saturated group and dual-boiler architecture and adds programmable profiles that Micra lacks; Micra has a rotary pump and brand prestige, while the LITA SIGMA has a gear pump

Question 29

Is the tablet included with the LITA SIGMA?

Accepted Answer

No. The Wendougee-branded Android tablet is a paid accessory; the machine is designed to be driven from any Android or iOS phone or tablet you already own, using the free E-Bar app. Setup requires a phone or tablet once; day-to-day operation can be done entirely from the Intelligent Disc and paddle.

Question 30

How often should I descale and backflush?

Accepted Answer

Daily: flush the group for 2–3 seconds and wipe the steam wand. Weekly: backflush with a blind basket and espresso-safe detergent (e.g., Cafiza). Every 3–6 months: descale the brew and steam boilers with a citric-acid or manufacturer approved descaler. Interval depends on water hardness — soft-water users at <50 ppm can stretch to 6 months.

Question 31

Are spare parts available in the EU?

Accepted Answer

Yes, spare parts are available

Question 32

How do I update firmware on the LITA SIGMA?

Accepted Answer

Firmware updates are pushed through the E-Bar app over Bluetooth. When you open the app with the machine connected, it checks Wendougee's servers and prompts you to install any available update on the controller and connected peripherals.
