Miele Guard M1 Cat and Dog Flex review: The gold standard for pet hair

Everyone, including me, seems to be opting for a cordless vacuum cleaner these days. Yet in a world of robot vacuums, the Miele Guard M1 is reliably excellent, and so much more powerful than any vacuum cleaner I’ve ever tested.

The model I tested is specifically designed for homes with animals, as it comes with an extra air-driven turbo brush. To find out more, I tested the Miele Guard M1 for a month, during which my dog shed as much hair as ever, and my toddler wreaked his usual havoc around the house. Read my full Miele Guard M1 Cat and Dog Flex review below to find out more.

Miele Guard M1 Cat and Dog Flex review: Design

The Miele Guard M1 Cat and Dog Flex is, by design, a bagged cylinder vacuum with four different cleaning modes, which are controlled by buttons on the front of the machine. The powerful suction is adjusted to suit whatever you’re cleaning, whether that be cut-pile carpets and rugs, loop-pile carpets, hard floors, or curtains and textiles. The Cat and Dog version comes with a Turbobrush floor head for ingrained pet hair and dirt.

The Miele Guard M1 Cat and Dog Flex comes with three different attachments, which can be stowed in the vacuum itself, and make it easier to clean in hard-to-reach areas. The bags are easy to remove and dispose of, and there’s a replaceable Air Filter, which neutralizes odors — ideal for pet owners.

The Guard M1 has a 25-foot (7.5m) power cord, so despite any reservations you might have, you won’t feel like you’re stuck to a wall when vacuuming. The vacuum has a 33-foot (11-meter) operating radius.

The downside, compared to cordless vacuums like the Dyson V12 or the best robot vacuums, is the weight. The Miele Guard M1 comes in at 16 pounds (7.3 kg). I didn’t find it overly heavy, and actually found it more comfortable to use than my Dyson V8, as the weight wasn’t resting on my hand. Still, it’s not nothing, especially if you’re cleaning a house with a lot of stairs.

Unboxing the Miele Guard M1 was extremely easy and just involved slotting the vacuum hose together. The retractable handle can be extended at the press of a button, making this convenient for users of all heights. I found it extremely easy to set up and was ready to go in minutes. I wish the vacuum came with an extra dust bag or two for the price, but I did find a QR code in the box to get an additional one for free.

I tested the Miele Guard M1 in the ‘Black Obsidian’ colorway, which looked beautiful, but unfortunately has gotten pretty scratched in the month I’ve been testing it. This could be my fault, however, as it’s been stored in a cluttered under-stair cupboard.

Talking of my cluttered under-stair cupboard, the vacuum can be stowed upright or vertically. It’s definitely bigger than a stick vacuum, but it doesn’t take up too much space.

Miele Guard M1 Cat and Dog Flex review: Performance

I tested the Miele Guard M1 for a month to see how it performed in various settings. I added challenges like sprinkling oatmeal on my jute rug and trying to pick up small gravel stones on hard floors. I used the Universal Floorbrush, as well as the Turbobrush, to see how both compared.

What is it like to use on carpet?

I tested the Miele Guard M1 on two rugs downstairs, one of which is jute, as well as my low-pile carpet on the stairs and in the bedrooms. The carpets are cream, which is a nightmare with a dog and a toddler, but it does make it easy to spot dust, hair and debris left behind.

I found the suction power incredible on carpet, especially when using the Turbobrush. The Miele Guard M1 has a suction power of 1,200 AW, which I found extremely powerful, especially compared to the 150 AW of my Dyson V8. I was able to make those satisfying lines in my carpets, even if they only lasted until my toddler got home from daycare.

The Universal Floorbrush was also excellent on carpets, and I found the smaller attachments useful on the stairs.

What is it like to use on hard floors?

Did I mention how powerful the Miele Guard M1 was? The suction power is extremely impressive on hardwood floors, which I have downstairs in my Victorian terrace. I sprinkled various debris on the floor, including oatmeal and a mix of flour and sugar, to determine how well the Miele Guard M1 coped. As expected, the vacuum had no trouble sucking up all of the debris in one to two passes.

The suction power was also a resounding success on pet hair. Any dog owner will be used to spotting small furballs in the corners if you’ve skipped a few days of cleaning — especially in the summer, when my spaniel seems to shed more than usual. The suction power seemed to pull the pet hair towards the floorhead before even touching it.

I found it super easy to switch between the modes as the controls are pretty much all foot-powered, meaning you don’t have to stop and bend down mid-clean.

The Miele Guard M1 extremely easy to move around. The castor wheels swivel in all directions, and the cord was long enough for me to reach all areas of my home without having to unplug and move the plug socket.

Noise levels

The Miele Guard M1 wasn’t overly noisy, but I definitely found the Turbobrush was loud. I was so impressed with the results that I didn’t mind at all, but I probably wouldn’t vacuum upstairs while my toddler was napping.

What are the hand attachments like?

The Miele Guard M1 comes with three different attachments:

• An upholstery nozzle, which I used to get dog hair and debris off the sofa where he sleeps.
• A dusting brush, which is a round brush that I use to dust the top of my bookshelves. This is probably the attachment I’d use the least, but I think if you need to clean shutters or around the top of your door frames regularly, it’s a handy one to have.
• The crevice nozzle, which I typically use to catch all the crumbs under the TV stand, or in hard-to-reach corners. This wasn’t particularly mind-blowing, but it’s a super useful tool you’ll probably use every clean.

I loved the fact that you can stow the attachments in the front of the machine, as I can’t tell you how many times I’ve lost my Dyson’s attachments.

Miele Guard M1 Cat and Dog Flex review: Ease of cleaning

I found the Miele Guard M1 extremely easy to empty, thanks to the mess-free ComfortFit bag system, which keeps the bag secure, so none of the dust escapes when you’re emptying it.

After a month of testing, I didn’t need to swap the bag out, but I wanted to for this review. How long the bag lasts obviously depends on how often you use the vacuum. The Miele Guard M1 comes with a handy dust bag indicator on the top of the device, so you’ll be able to see at a glance when you need to swap it out.

The dust bags are an extra cost, but in my mind, you don’t have to worry about charging the vacuum, so it’s a small price to pay! For the Miele Guard M1, you’ll also have to swap the Exhaust Filter, which Miele says lasts for around 50 operating hours, or about a year’s worth of use.

The only downside I found from a cleaning perspective is that my long hair did get wrapped around the Turbobrush, and after a month, I had to cut it out. That said, I’ve found this happens with every vacuum cleaner I’ve ever used.

As mentioned above, after a month of testing, the vacuum itself got pretty scratched up, although I blame the mess in my cupboard, not Miele, for this. If you’re super fussy, it does also show a lot of fingerprint marks, but I wouldn’t let this put you off.

Miele Guard M1 Cat and Dog Flex review: Comparisons

If you’re a fan of the brand but want more tech on board, it’s worth looking at the Miele Guard L1 Comfort XL. The most basic option of the Guard vacuums is the Miele Guard S1, priced at a very reasonable £199. However, it doesn't have all the added features or bells and whistles.

Another option for pet owners is the Shark Rotator Pet, which we rated 4.5 stars for its ability to remove stubborn hair.

Miele Guard M1 Cat and Dog Flex review: Verdict

If you own a pet and you’re looking for a powerful, high-quality cylinder vacuum, I don’t think you can go wrong with the Miele Guard M1 Cat and Dog. The suction power is incredible, and the two different floorheads make keeping your home clean a doddle.

If you’re thinking of making the switch from a cordless vacuum, I wouldn’t let the cord put you off. The cleaning power makes up for the seconds it takes to pull out and retract the cord. Plus, with an 11-metre zone, you’d be hard-pressed to find an area of your home you can’t reach, even if you do have to swap plug sockets one or twice.

The vacuum itself is easy to maneuver, and it’s lightweight enough to hold in one hand as you vacuum the stairs. I swapped to the Miele Guard M1 from my Dyson V8, and I’m never going back.
