MACHINE The Siemens EQ900 plus TQ907GZ3 is built for a very specific buyer: someone who wants two kinds of beans on hand, high control over recipes and a premium cleaning system. It is an unusually feature-rich automatic coffee machine, but the important question is whether those features justify the purchase and ongoing maintenance costs for your household. The answer depends less on how many menus it can display and more on whether you change beans, make several types of milk drink and value fine adjustments.
Exact UK configuration
Siemens' UK specification for TQ907GZ3 confirms a 2.3-litre water tank, two bean containers, two separately adjustable electronic grinders, 6.8-inch iSelect colour touchscreen, integrated milk system and Home Connect compatibility. Siemens markets the dualBean arrangement as a way to switch between bean types without emptying a shared hopper. The product is not interchangeable with a one-grinder EQ900 or a US catalogue replacement; this review is tied to the exact UK article.
The official UK page lists approximate dimensions 392 × 315 × 470 mm (height, width, depth). Its large water tank reduces refilling interruptions, but the footprint and mass demand a suitable worktop. Buyers should check overhead clearance and how easily the tank and milk container can be removed in their intended kitchen position.
Why dual grinders matter
A two-hopper machine is not automatically better for someone who drinks a single roast. Its benefit appears when a household wants regular and decaf, or alternates between a lighter and darker bean. Having a separately adjusted grinder for each hopper means settings can stay closer to the preferences for that bean, instead of repeatedly changing a shared adjustment. It also avoids some of the compromise inherent in a removable, single-grinder hopper system.
Siemens combines this with its beanIdent settings and baristaMode controls. These are tools for tailoring coffee, not a guarantee that a machine automatically knows the perfect extraction for every bean. Grind, strength, temperature and serving size still require tasting and informed choices. People who dislike menus may find the options excessive; enthusiasts may appreciate that they can move beyond simple strength presets.
Independent evidence: encouraging, but attribute it
In a TechRadar hands-on review published 22 February 2025, the reviewer praised the Siemens EQ900 Plus milk preparation, reported very good espresso and particularly liked its macchiato. The same review noted the high price and questioned how much extra value the Plus model's cleaning convenience delivers over the standard EQ900. Those observations are from TechRadar's test machine, not original Machine & Bean testing, and should not be treated as measurements of every TQ907GZ3 installation.
A separate Which? listing identifies the UK TQ907GZ3 as a model in its laboratory review database, but its full test findings require access. We do not claim to know its paywalled espresso ratings or reproduce an unpublished score. Between official product documentation and a well-identified hands-on family review, the machine has a more substantial evidence trail than some newer exact-SKU products; gaps nevertheless remain.
Milk preparation and home routines
The integrated milk container lets the machine dispense milk-based coffees without a manual steam-wand step. For someone preparing several cappuccinos or flat whites in a morning, consistency and reduced handling may make a bigger difference than the bean hopper arrangement. TechRadar's reviewer found the milk foam especially good, which is a positive independent signal, but milk brand, fat content, temperature and cleaning will affect repeatability.
Storage of user profiles and recipe preferences is particularly relevant to shared homes. Siemens documents the ability to save drinks and tune more detailed brewing parameters; there is a genuine usability question over whether the household wants that many choices. A machine may be technologically impressive while still taking more attention than a basic espresso button. Check the menus in person if possible before committing to the premium.
Cleaning, cartridges and the hidden budget
The signature autoCalc'n Clean system uses cartridge-assisted automatic cleaning and descaling. That can substantially change the effort profile of ownership, but the cartridges are consumables, not a one-time feature. The user still needs to manage the milk container, used coffee and ordinary hygiene. Before buying, price the correct cartridges and check their stated replacement schedule in the manual rather than assuming a fixed annual cost.
TechRadar also questioned the extra Plus premium when some simpler EQ900 variants share much of the core brewing functionality. That is a useful prompt to compare models like for like: dual grinders and cleaning convenience are separable benefits. Ask which one would actually earn its place in your kitchen before paying for both.
UK value and alternatives
Our catalogue records a Siemens UK list-price reference of £2,199 for TQ907GZ3, with pricing checked in October 2026. That is not a live Amazon sale quotation, and the retailer destination should determine today's current asking price and availability. The comparable JURA and KitchenAid machines differ in whether they offer two independent grinders, the size of the screen and the approach to cleaning. A lower-priced machine with one hopper may be more rational if everyone drinks the same beans.
Be particularly careful with marketplace listings that omit the TQ907GZ3 suffix or use general "EQ900" photography. The Plus and non-Plus lines can appear deceptively similar, and the exact UK SKU must match before any purchase or warranty decision.
Machine & Bean verdict
Best for: committed UK coffee drinkers, including mixed-decaf households, who want two grinders, extensive recipe control and cartridge-assisted maintenance.
Reasons to shortlist: independent bean paths, fine electronic grind adjustment, large touchscreen, substantial tank and an established published hands-on evidence trail.
Reasons to hesitate: very high ownership cost, cartridge expenditure, large footprint and the possibility that elaborate control becomes unnecessary complexity.
We regard the TQ907GZ3 as a premium capability-led choice, with positive attributed independent observations but no invented Machine & Bean test score.
