So when I saw this product, I was a bit surprised, but with the growing interest in cordless vacuums, it shouldn’t come as such.

The Miele TriFlex HX1 has a quoted battery life of up to 60 minutes with no powered brush heads in low power, and up to 17 minutes in high power mode with the powered brush head attached. Charging from empty takes a quoted four hours. In our tests, in Max mode the HX1 lasted 12mins 11secs and in low power mode it ran for 28mins 11secs; the powered cleaning head was attached and running in both tests. The overall score is skewed by its poor performance vacuuming quaker oats. Otherwise, it would have been a higher average. In Australia the Miele Triflex HX2 range also includes the Triflex HX2 Performance, Triflex HX2 Racer and Triflex HX2 Cat & Dog Plus. But with suction-only tools, those figures go down considerably to more bearable levels below 80 decibels. Availability of parts I would not recommend this for cleaning long strands, but it would suffice for shorter strands. Edge cleaningThe floor cleaner here is similar to those seen on Dyson cleaners, in that it automatically detects the floor type and reduces rotational speed on hard floors to save energy and prolong battery life. However, in the Trfle HX2 Pro, this feature is only available on the Eco and Max power settings with the Multi-Floor XXL Electrobrush is fitted. In the box, you'll also find a crevice nozzle, dusting brush, upholstery nozzle. IIn the before and after shots above, you can see, you can see that the passes were clean, and there wasn’t any visible debris left. Deep cleaning results Excellent carpet cleaning performance: The Triflex HX1 is built to clean this surface well thanks to the wide nozzle and stiff bristles. The floorhead also features a light strip along its front edge, which we found super-useful for lighting up areas under furniture, or revealing finer dirt on the hard floor in lower lit areas of the house. Note that this is only present on the Triflex HX2 Pro and Triflex HX2Cat & Dog models. Miele also includes a separate Hardfloor Care soft roller for use on hard floors and a Carpet Care roller brush for more delicate carpets and rugs. It does mean that you'll need to stop vacuuming to remove and swap out the bristle roller brush, but they're a good option for those who are particularly concerned about protecting their floors. This is confirmed in the cleaning results (up next), where the Triflex had nearly identical deep cleaning results in the mid and max setting.

It won’t hold much dirt, but I like its placement as an upright – another reason why I prefer using it in this configuration. With a removable 2,500mAh, 25.2V lithium-ion battery – which plugs directly into the supplied mains adapter – and a filter you never need to replace, the Miele TriFlex HX1 is a practical beast. Indeed, if you shell out for the top model you also get a pair of batteries for your money, which means you can leave one charging while cleaning with the other, then swap over when the juice runs low. Miele's tech made the Trifle HX2 Pro a dream to use when transitioning from carpets to hard floors, with the level of suction remaining consistent. Manually switching between the speed settings was just as easy. We preferred the Eco and Max settings, since we have long-pile wool carpet in our home; the Min setting just didn't cut it for us. However, when switching settings, it took a second or so for the vacuum cleaner to power up or change gears – enough time to be noticeable – so this vacuum isn't as responsive as some other vacuum cleaners we've tested. The price is at a sweet spot for the performance it brings to the table. You could argue that the Cat & Dog offers more, but it’s slightly overpriced, in my opinion.

The Verdict: Base Model is Excellent Value on Carpet

You can get two batteries out of the box by purchasing the HX1 Pro, plus an extra charger. Ergonomics and Usability The Miele TriFlex HX1 doesn’t quite have the cleaning power to dislodge Dyson as king of cordless vacuum cleaners, but its adaptable layout certainly sets it apart from the crowd.

This board width enables it to vacuum more debris than a narrower head but at the expense of portability. Fortunately, it did better with other debris, but I’m pointing out that there are limitations. Battery It only has a traditional brush roll, and while Miele says it’s “multi-floor,” I wouldn’t recommend it on hard floors. I tested the Miele Triflex HX1 with various debris like quaker oats, quinoa, pet litter, sand, coffee grounds, and hair. We test each cordless vacuum multiple times on carpet, laminate and floorboards. To assess performance, we cover each surface with dust and calculate the percentage the vacuum removes. We repeat this process with an assortment of debris, including biscuit crumbs and pet-hair. All of these tests are repeated again in handheld mode. Both modes are then tested in a variety of other cleaning scenarios, such as on stairs or in a car. To test design, we investigate each product’s specifications. This includes testing the battery’s maximum run-time and assessing how easy it is to use.

Staying true to its roots, the Triflex utilizes a wide nozzle at around eleven inches – more than an inch broader than other brands. The brush roll is on the slim side with stiff bristles, which is why it didn’t do well with longer hair strands (more on that later). Miele utilizes a VART Li-ion battery rated at 2500 milliamps with a claimed run time of 60 minutes.

According to Miele, the TriflexHX2 Prois 60% more powerful than its predecessor, the Triflex HX1 – a model that had already impressed for its power in our review. This improvement comes by way of the new Digital Efficiency Motor, which works in combination with Miele’s Vortex technology (mono-cyclone design) and Multi-Floor XXL Electrobrush to deliver exceptional cleaning power.The rotating beater (or brush bar) links with intelligent detection of floor type to reduce the rotational speed on hard floors. This, Miele says, saves energy and prolongs battery life; but we found that it also goes some way towards protecting soft wooden flooring. The feature also automatically determines the speed setting required, depending on the type of flooring. Despite not having a soft roller tool, the Miele Triflex did well cleaning this area, as you’ll see in the before and after photo below.

It also comes with an extra battery that doubles the run time from 60 minutes (claimed) to 120 minutes. Dustbin design and capacity Enter the serial number for your appliance in the white box. The serial number can be found on the data plate. Please only enter the number after the slash. Self-standing feature: My favorite configuration is the upright mode, where it can stand on its own. Great that there's two batteries, but the runtime is not so great on the more preferred speed settings.
