Morpilot sells this milk frother through Amazon, not through its own brand site. That shapes the facts available: everything that can be documented about the HS001 model comes from five manufacturer texts in the Amazon catalogue and from the product photo for the ASIN B0FPLZ313X.
What is documented: a white base with 600 watts, a jug made of glass with a high borosilicate content, separate capacities for heating and for frothing, and four programmes that, according to the manufacturer, one click starts. Our price box shows approx. €45.99 on Amazon.de. We have not had the appliance in our hands.
HS001 and a brand site that does not know the appliance
The Amazon catalogue lists the frother under the model number HS001. On morpilot.com, the only site that presents itself as a brand site, this number does not appear. The range there comprises 39 items, including solar lights, massage devices, pet products and gaming accessories, plus exactly one milk frother. That is a different appliance: six functions instead of four, black glass instead of clear, and in the brand shop it costs several times as much in US dollars.
The break goes in both directions. The brand site does not point to Amazon either: the product page of the black frother has no link to an ASIN, and the buy button stays in its own shop. What you can read about the HS001 before ordering is therefore found entirely in the Amazon catalogue.
There is also a pitfall that matters when ordering. On Amazon.de, several very similar Morpilot frothers run under their own ASINs, and titles and photos look confusingly alike. Collections of manuals online also list a Morpilot variant with a different wattage and different capacities. We have deliberately left these figures out, because they directly contradict the information for our ASIN. What is stated here applies to B0FPLZ313X.
Red, blue, purple, green: what one click triggers
Four programmes, and Morpilot assigns them to colours. RED stands for warm, dense milk froth, BLUE for cold milk froth, PURPLE for hot milk, GREEN for warm, airy froth. Which colour is currently active is shown by a light signal on the base, which the manufacturer expressly classes as an operating aid.
On the product photo for the ASIN there is exactly one round button with an on-off symbol on the white base. Below it, four small cup symbols are printed, labelled Red, Blue, Purple and Green. That fits the single click from the programme description. In the cleaning note, however, Morpilot speaks of buttons in the plural that must be protected from splashing water.
Two stirring inserts are part of the delivery, a froth mixer and a heating mixer. Morpilot even reveals in the delivery list where they sit in the box: the froth mixer in the jug, the heating mixer under the base. If you miss the second insert when unpacking, lift the appliance. On the photo, both parts lie one below the other at the left edge of the picture, the upper one black and without a coil, the lower one with a metal coil around the rim. On the product page for the SM 3587, Severin shows a smooth insert for heating and a ribbed whisk for frothing, and the two-part split on the Morpilot suggests the same division of tasks.
Also in the box: a cleaning brush and the printed instruction manual.
500 ml warm, 250 ml froth, then an enforced pause
Morpilot states two quantities, and they are deliberately different. 500 millilitres apply to hot milk or cocoa, 250 millilitres to milk froth, hot or cold. The reason is headroom: frothed milk takes up much more space than liquid milk, and a jug filled up to the heating limit pushes the froth out at the top. That cocoa appears on the same line as hot milk also means that the jug is expressly intended for more than pure milk, and anyone stirring cocoa uses the full capacity that lies idle with a plain cappuccino.
On the product photo, three lines are set into the glass, two of them labelled MAX, one MIN, each with a small symbol beside it. The two MAX marks probably belong to the two quantities stated.
Morpilot does attach a condition to the heating function, though. Before you start it again, about 4 to 5 minutes should pass, otherwise the temperature would be affected. In our view that is the hardest everyday point on this appliance: if you make several hot milk drinks in a row in the morning, build the waiting time firmly into the routine.
An automatic switch-off function is also documented. Morpilot justifies it with safety in use.
What borosilicate glass does and does not do
Glass with a high borosilicate content, heat-resistant and shatterproof (as Morpilot puts it, “explosion-proof”), easy to clean: that is how Morpilot describes the jug. The first part of that is a statement about the material, and it can be put in context.
Borosilicate glass contains boron oxide, and that reduces thermal expansion to a fraction of what ordinary soda-lime glass shows. When hot milk meets a cold jug, the inside expands more than the outside, and cracks arise from this stress. The less the material moves during temperature changes, the smaller the stress stays. That is why laboratory glass is made of borosilicate, and in an appliance that heats milk we consider the material the factually correct choice.
What does not follow from this is resistance to falls. Thermal shock resistance and impact resistance are two different properties; borosilicate is not safety glass. What Morpilot means by explosion-proof is not explained in the manufacturer’s text, and no standard, glass thickness or drop height is given alongside. We repeat the word, but cannot confirm it.
The practical gain is in another bullet: the clear glass lets you see the state of the froth at all times. With an opaque jug like the WMF Stelio, you only see after the run whether it worked. While you are getting to know a new type of milk, you can see during the run whether it forms any froth at all.
That leaves the upper limit. Our guide how to froth milk advises not taking milk for froth above about 65 degrees, because above that the protein framework that supports the froth breaks down. Whether the Morpilot stays below that can only be settled with a thermometer.
Cleaning in the manufacturer’s words
Morpilot separates two components cleanly, and we give the wording because a smoothed-over version costs money here.
The removable jug section can be taken off and put in the dishwasher. That is the only dishwasher approval the manufacturer gives, and it expressly applies only to the jug.
The base is wiped with a clean cloth to keep it dry. In the same breath, Morpilot writes that water must be prevented from splashing into the base and the buttons. What is meant, then, is dry wiping; the base should not get wet in the first place.
What the cleaning brush in the box is for follows from the material. Milk protein settles as a thin film on every heated surface, and on glass you see it instead of overlooking it. The first step remains the most effective: rinse with warm water straight after pouring, because dried-on protein comes off much harder than fresh.
What Morpilot does not state
On the appliance itself: no height, no width, no depth, no weight, no cable length, no voltage or frequency, and as the only connected load the 600 watts from the title. On operation: no heating principle, no temperature in degrees, no switch-off threshold, no duration of a run, no minimum fill quantity in millilitres, no noise level, no quantity for the three lines in the glass and no assignment of which of the two stirring inserts belongs to which colour programme. You should not read the term heating mixer from the delivery list as a hint at the heating technology; what is meant is a stirring insert.
On materials: nothing on the base, lid and the two stirring inserts. Whether a lid is supplied at all is left open by the delivery list, although the product photo shows one sitting on the jug. On a non-stick coating there is neither a promise nor an exclusion. Around the purchase, the warranty period and conditions, spare parts, descaling instructions, approval for plant-based drinks, a rinse programme and a maximum temperature for the jug are missing. And on the company: no country of manufacture, no year of market launch, no manufacturer’s address, no EU representative, no approval mark.
That it can be done differently is shown by WMF: for the Stelio, the user manual gives a minimum fill quantity of 100 ml, a rated voltage of 220 to 240 volts and protection class I.
What else is worth considering?
Three appliances from our milk frothers category are what a buyer really weighs against the Morpilot. Two of them cost the same or less. The Severin appears as a deliberate outlier at the top of the table; it costs around two and a half times as much and shows what temperature selection and programme variety cost.
| Model | The difference | Price | Our rating | Choose this if |
|---|---|---|---|---|
| Morpilot 4-in-1 600 W (this one) | Clear borosilicate glass jug, 250 ml froth, four fixed colour programmes | approx. €45.99 | 8.2 | you make one to two cups at a time and can do without a datasheet |
| WMF Stelio 500 Watt | Milk jug made of Cromargan instead of glass, at most 150 ml of milk per froth programme, three instead of four programmes | approx. €45.99 | 8.6 | you want to read the instructions beforehand and can manage with a smaller froth quantity per run |
| Simpletaste 4-in-1 | Jug with non-stick coating inside, base material not stated, 115 ml froth, a spare whisk in the box | approx. €29.99 | 8.0 | saving €16 matters more to you than a transparent jug |
| Severin SM 3587 | Adjustable temperature, 13 programmes, 350 ml froth | approx. €114 | 9.4 | you want to determine the milk temperature yourself |
The prices are the guide values from our price boxes; at the catalogue retrieval in early September 2026, all four were at most one euro off. The rating is our assessment based on the data comparison. The technical information on the three other appliances comes from manufacturer information, for Simpletaste from the manufacturer’s text in the Amazon catalogue.
When the Morpilot suits and when another appliance does
Start with the number of cups. A froth filling of 250 ml is, in our assessment, enough for two cappuccinos, and milk coffee with plenty of warm milk is exactly the case the larger heating quantity is meant for. From the second hot run in a row, the heating pause sets the pace, and with three or four milk drinks in a row the morning gets sluggish.
The second question is temperature. If you want to bring milk to a specific point, for instance because you heat cocoa differently from milk froth, the Morpilot is the wrong appliance: there are four fixed programmes and no setting in between. With the Severin SM 3587, the temperature can be set between 45 and 65 degrees according to Severin, plus dedicated programmes for cashew milk, soy milk and lactose-free milk. At approx. €114 it costs around €68 more than the Morpilot at approx. €45.99.
Then the kitchen itself. In a household with small children or little space next to the sink, there is more in favour of a jug without glass. The WMF Stelio has, according to WMF, a milk jug made of Cromargan, that is, stainless steel. The Simpletaste 4-in-1 costs approx. €29.99, which is €16 below the Morpilot, and has a jug with a non-stick coating inside, although Simpletaste does not name its base material.
Who is it suitable for?
Morpilot names cappuccino, macchiato and latte as the drinks the appliance is intended for, and for that the jug has a latte art drip-nozzle design, that is, a narrowing spout. On the product photo it can be seen as a small lip at the left edge. With it, Morpilot promises pouring without spilling and even writes that beginners can achieve beautiful latte art effects with the appliance.
That is an advertising sentence, and other manufacturers also advertise with latte art. A comparison that measures the pouring ability of such appliances against a steam wand does not exist, according to the research for our latte art guide. The guide nevertheless rates the steam wand as the tool with the most control, because there you steer air intake and temperature yourself. With RED and GREEN, the Morpilot offers two warm froth levels, dense and airy, but both as a fixed programme.
Our assessment from this: anyone who wants to learn latte art seriously is poorly served by this appliance and better off with a machine with a steam wand. For the cap on a cappuccino, by contrast, the design fits; Morpilot expressly names cappuccino as a purpose of the appliance. Which class of appliance suits your preparation at all is sorted by the coffee finder by budget and need.
