If you are trying to figure out the differences between the DC40 origin model and that of the DC40 multi-floor, however are struggling -- then there is good reason for that -- because there actually isn't any. Under Dyson it has simply undergone a name change from the Dyson DC40 multi-floor to that of the DC40 origin model (the reason is believed to be simply that they are now able to make the DC40 for much less & thereby reduced the price -- when sold directly from Dyson.com).

Hence both versions share the exact same specifications and features with regards to power (where the motor enables around 200 AW of constant suction), fitted technology (radial root cyclone -- allowing it to generate high centrifugal forces, to operate on a bagless mechanism and to not suffer with loss of suction & advanced cleaner head that self-adjusts depending on the floor type you are cleaning to get a more optimal suction performance), practical features (the pretty extensive bin capacity: 1.6 litres, compactness with dimensions: 107 x 35 x 31 cm & extensive max reach: 12.4 m + cord length: 7.5 m) & offers the same high standards in mobility (due to it only weighing in at 6.7 kg as well as being fitted with the centralised Dyson ball mechanism to allow awkward turning to be made simple).

Other aspects of course remain the same too -- where each get an industry leading 5 year warranty coverage of both parts & labour for your DC40 Origin (DC40 Multi-floor). Moreover, you are fitted with an advanced & easy to maintain filtration system that prevents allergens & dust particles from being expelled into the air (such a  vacuum is particularly recommended for those who are either allergy sufferers or asthmatics). The DC40 origin & DC40 multi-floor also get the same attachments & accessories -- the standard combination tool (that can be used both as a crevice tool to vacuum tight & awkward gaps as well as a brush tool by sliding down the nozzle to allow powered dusting) as well as a stair tool (which can also be used for upholstery).

Which Should You Buy?

So to sum up then which one you buy -- all it basically just comes down to is which offers the best price from the two (& that being the cheapest price, unless you find any particular deals with one over the other e.g. a free Dyson Car cleaning kit). You may also be willing to consider a refurbished DC40 multi-floor as well, which is obviously subject to a significant discount (due to being previously broken & then fixed and for the fact of being possibly second hand) & although it works likes new, you aren't getting the same 5 year warranty backing (although you should check -- because generally you get between a six month to two year guarantee).

Dyson DC40 Vs DC40i

If we compare the DC40 Origin model with the DC40 indie (independent) -- all the main aspects of what has been stated above remains the same, however the DC40i gets an extra attachment: the Dyson stiff bristle brush -- which basically helps remove dug in dirt from soft carpets by producing a 'popping' motion to flick the dirt up & to then be sucked into the vacuum's bin. Apart from this & a slight colour change (from classic yellow to a red/silver mesh), there is no difference.

Dyson DC40 Origin Vs DC40 Animal

Likewise, when comparing the DC40 origin to that of the DC40 Animal -- the only difference is that the latter comes with a specially engineered turbine tool designed for effective & efficient pick up of pet hair -- the highly regarded Tangle Free Turbine tool. So basically the Animal version is intended for those who keep a pet which causes a hair problem in their house. Again, though there is no difference in performance between the two -- but there is a colour change (with the Animal version being purple).
