Each of the three models in the Triflex series can stand like an upright vacuum, reach under furniture like a cordless vacuum, and fit into tight spaces like a handheld vacuum. While the Miele Triflex HX1 Cat & Dog model makes it seem like it’s exclusively a pet vacuum, technically all three models in the lineup should tackle pet hair equally well, since they all have the same brush head. And you certainly don’t need to own pets to maximize the perks of this Triflex model.

The Miele Triflex HX1 Cat & Dog also beats its competition in the “feels” department. As in, it feels good when you clean with it, which might incentivize you to vacuum more often. It also feels sturdy and well-engineered.

The only downside is that the Miele Triflex HX1 Cat & Dog is not as powerful as the competition that falls into a similar price range, making it a slightly expensive purchase for the performance you receive.

What we like

It has a long battery life

If you're a cleaning fanatic, you can purchase additional batteries to double your vacuuming time.

One major feature we appreciate about the Miele Triflex HX1 Cat & Dog is that it can clean your floors, your curtains, and your car on one charge.

Our testing shows that you can get up to 60 minutes of cleaning on its lowest setting and about 17 minutes on its highest. To put that into context, the Dyson V11 Torque gets nine minutes per charge on maximum, and the LG CordZero runs for eight minutes per battery on the highest setting.

Plus, the battery is removable. If you ever want to double your amount of cleaning time, you can purchase an additional battery to tag in.

This cordless stick vacuum really is three-in-one

At first glance, the Miele Triflex HX1 Cat & Dog looks outrageously expensive, but if you look a little deeper, the vacuum is actually more economical than you think. You see, the Miele Triflex HX1 Cat & Dog transforms into three distinct forms. This works by detaching and rearranging the cordless stick vacuum’s handle, motor, and wand.

The Miele Triflex HX1 Cat & Dog is exceptionally easy to assemble.

Most cordless vacuums fall over when you leave them unattended, but not the Miele Triflex HX1 Cat & Dog. It boasts an upright mode that stands up all on its own and cleans just like any other upright vacuum you’ve used, only lighter and easier to maneuver.

The other two forms the Miele Triflex HX1 Cat & Dog takes are more Dyson-like: a cordless that feels good in the hand and is light, but sturdy, so lifting it up to clean furniture and upholstery is easy; and a handheld, which is a little bulky, but the swivel joint in the power brush heads let it get into the tight spaces.

It feels good to clean with it

There’s a concept in chemistry called activation energy—the amount of energy needed for a reaction to start. For some of us, vacuuming requires a pretty high activation energy in order to propel us from binging Netflix on the couch to cleaning our floors and cushions. The Miele Triflex HX1 Cat & Dog may just be the activator you need.

The TriFlex has the reach of a Dyson, only better.

Thanks to its three configurations, the Miele Triflex HX1 Cat & Dog offers users a lot less hassle. Imagine cleaning your floors: When you reach your couch, instead of getting out another vacuum to clean beneath it, you can just convert your Triflex to its handheld mode.

True to its name, the Miele Triflex HX1 Cat & Dog is good with pets, or at least picking up after them. During testing, we really liked the compact powered brush for cleaning upholstery, and the LED lights on the Triflex’s brush head and swivel joints make it much easier to track down hair clumps and dust bunnies under furniture.

What we don’t like

Its suction power is weaker than its competitors

Miele TriFlex Comparison

While the Dyson V11 (rear) picked up more dirt per pass, we think the Miele TriFlex (front) can match it per charge.

One of the major cleaning tests we do in our lab involves measuring how much sand each vacuum can pick off a short-pile carpet.

Regrettably, the Miele TriFlex picked up about 65% of the testing dirt we laid out for it. This means it's above average in suction power, but it still lags behind the Dyson V11 and the LG CordZero, which picked up 95% and 90% respectively.

While the TriFlex isn’t as powerful as its competitors, we still think it’s capable of cleaning your home just as effectively. The math works out in the TriFlex’s favor. Comparing charge to charge, the longer battery life means that the TriFlex has the potential to pick up more dirt overall.

Should you buy the Miele Triflex HX1 Cat & Dog?

Yes, if you’re looking for a cordless vacuum that can do it all.

Long battery life combined with sturdy attachments, and the ability to transform into three different types of vacuums means there isn’t really a cleaning problem the Miele Triflex HX1 Cat & Dog can’t solve.

If you own a Miele upright or canister, but you’re looking to downsize, the TriFlex will provide the same high-quality engineering but also cuts the cord.

If you want a cordless vacuum with more suction power, try the Dyson V11 Torque which is still the king of the hill when it comes to raw power.
