After even the slightest hint of dirt on them  the 'Lloyd premium mat' stinks like spam.

A couple of things.

It depends on the material and how the mats are treated. Assume that
the manufacturer wants repeat business, that they know what they are
doing and that they understand the nature of floor mats. This includes
exposure to salt, water, road grime, foot grime, sand, freeze-thaw
cycles, temperatures in excess of 130F and below -50F (if in Alaska)
and so forth.

So, I would expect that they use solution-dyed fibers treated with a
PTFE or PFE (AKA Teflon if trade-marked) type anti-stain compound that
is chemically bonded into the fibers.

Now, you have to define your cleaning methods. Road tar and the fine
emulsion that "grows" on roads being the mixture of brake dust,
regular dust, car leakage, tire rubber, water, salt, antif-freeze,
brake fluid, oil, transmission fluid and so forth if ground into any
carpet, will stick and stain. Coffee, soda, sugar-laden "droppings"
and so forth will also stain and attract yet more grime. And using a
vaccuum cleaner won't touch it this stuff.

Take your mats to a self-serve car-wash. Hang them on the clips
designed for that purpose. Soap them, then rinse them with the highest-
pressure setting. Between the soap and the rinse, hit them with a
stiff scrub-brush and maybe some extra soap such as a dish-soap. If
you have a power-washer, you can do this at home. They should come
clean just fine. Hang them out to dry. Bring some paper or some-such
to put under your feet while you let them dry. Treated carpet should
come clean a bit faster. But given the nature of the grime involved,
that is the best method to clean the carpets.

A long way of saying: Try cleaning with more effective methods.
