Such a question is pretty difficult to answer outright -- for the simple fact that many of the vacuums Dyson offer are specific to different target markets (i.e people with different preferences and needs) and this is why I have attempted to roughly categorise them into the following sections:

  • 'Upright Vacuum Cleaner' - this category is for those who are after the best standard sized upright vacuum that Dyson offers, hence should be powerful, easy to use and offer the practical features that are needed to clean an average/large sized house to an excellent standard.
  • 'Cylinder Vacuum Cleaner' - likewise with the above category in that it should be powerful, comfortable in use and offer the practical features to offer a high performance clean, the only difference being the preference for a canister/cylinder based model over an upright.
  • 'Cordless Vacuum Cleaner' - here we take a look at comparing Dyson's Digital slim range as well as their handheld vacuums, for those who are wanting a cleaning machine that is lightweight, mobile and obviously cordless -- for getting quick and effective cleans done.
  • 'Compact/Lightweight Vacuum Cleanerthis category has an emphasis of the vacuum being compact (i.e for those who are short on storage space and looking to clean a small apartment) and/or need it to be comfortable to use for those with mobility issues for example, however are yet still after a vacuum with sufficient power.
  • 'Overall Value - 'Bang for Buck' Vacuum Cleaner' this section takes a look at (in my opinion) the 'best' vacuum you can get relative its price-tag (considers only the fully standard vacuums).
  • 'Accessory/Attachment Kitfrom all the Dyson kits available, this section explores which one provides you with i) the best tools as well as ii) the respective price attached.

I believe it to be logical to conduct the answer to the question: 'which is the best Dyson vacuum for you to buy?' within this manner as it would be somewhat pointless to compare a DC33 (which is one of the heavier of the range) with a DC50 (one of the lightest in the range) with someone who is looking for the best 'lightweight' Dyson vacuum to buy (as they may perhaps be older or have mobility issues)-- instead it would be better to consider which is better between that of the DC24 (also a lightweight upright) to that of the DC50. Besides, it is obvious there is not one best overall vacuum that suits everyone.

Best Upright Vacuum Cleaner

The Dyson DC41 Animal Complete

The best upright vacuum from the Dyson range has to be the Dyson DC41 Animal Complete -- this is pretty much the best of the bunch (probably on the entire vacuum market) with a rating of 4.6+ out of 5. Just to give a brief overview -- it is fitted with 255 Air Watts allowing it to have "twice the suction of any other vacuum" as well as being encompassed with the unique 'Radial Root Cyclone' technology meaning it doesn't suffer with loss of suction and can pick-up microscopic debris and dust. It is also fitted with the 'Ball' mechanism (as well as weighing in at only 17.1 lbs) making the DC41 incredibly easy and comfortable to use. Moreover, with the Animal Complete version of the DC41 you get 6 useful attachments: combination tool, stair tool, tangle free turbine tool, soft dusting tool, multi-angle tool, stiff bristle brush -- which you don't get with any other Dyson vacuum. Great value.

Other uprights to consider are the DC40, DC33 etc. however I feel they just lack a certain aspect that the DC41 has on them. For instance, the DC33 possesses similar power but lacks in 'ease-of-use' etc. whereas the DC40 is perhaps just as easy (if not being slightly easier given that it is lighter) but doesn't offer the same sort of suction power that the DC41 can.

Best Cylinder Vacuum Cleaner

The Dyson DC39 Animal

As some people prefer the cylinder (aka canister) based vacuums to that of uprights (and vice versa) Dyson have also released models in this kind of structure and the one that supersedes them all -- has to be the Dyson DC39 Animal. Again, a highly rated vacuum receiving roughly 4.3 stars out of 5 (if you haven't already be sure to check out additional reviews to get personal insight into the DC39) -- and others mentioned.

To provide a brief overview -- the DC39 is the most powerful vacuum that Dyson has within its entire range offering a huge 280 Air Watts -- meaning it sucks up more dust and dirt than any other cylinder vacuum. Likewise, to that of the DC41 it is fitted with unique radial root cyclone technology -- as well as specific acoustic engineering to help reduce noise levels. Moreover, it is one of the first cylinder vacuums to be fitted with the Dyson ball, hence unlike standard cylinder vacuums that operate on a fixed rigid wheeled system that have to be dragged back and forth (like a 5 point turn) the DC39 is able to turn on the spot. Given that the practical specifications are extensive -- the DC39 (like the DC41) is meant for those with the standard (to large) sized homes.

The other cylinder vacuums such as the DC32, 23, 47, 49 simply don't offer the same kind of power that the DC39 has (only just over half what the DC39 possesses) and for this reason the DC39 is the clear 'winner' within this category.

Best Cordless Vacuum Cleaner

The Dyson DC44 Animal

When it comes to this category (as of present) there are only really two to consider (both being from the Dyson Digital Slim range) and that is the DC35 (mark I) and DC44 (mark II) -- and as the latter is an 'update/upgrade' to the first it is clear the DC44 is the better model. Firstly note -- the DC44 model is meant for supplementing your cleaning with a fully sized vacuum. With the DC44 you are provided with two modes: standard on which you have a suction power of 28 Air Watts which lasts for 20 minutes and a boost mode that gives you 65 Air Watts suction lasting for 8 minutes. Moreover, as with all Dyson vacuums it is fitted with Root Cyclone technology to allow it to be bagless as well as not suffering with loss of suction. In all, I believe it to be a great option for those who are looking for an extremely lightweight vacuum due to mobility issues as well as being a great cleaning machine for the elderly, given its ease of use. Personally, I have found it particularly useful with cleaning high areas as it is so light such as curtains and cob-webs etc.

The other cordless vacuums to consider as said was the DC35 (which had a lower suction power and battery life) and DC34, DC31 etc. which were just handheld vacuums -- which the DC44 can double up as through simply removing the wand and fitting the cleaner head (or combination tool) to the actual motor handle.

Best Compact/Lightweight Vacuum Cleaner

The Dyson DC47/DC50 Animal

For those who are looking for a lightweight vacuum that is easy to use, carry around etc. (which could be for a whole host of issues) should lookk to some of Dyson's newest (early-mid 2013) vacuums -- for those who prefer canister: the DC47 Animal and for those who are after an upright: the DC50 Animal. 

To start with the DC47 it weighs in at just 6.08 kg with the actual vacuum base at just over 4 kg -- this doubled with the fact that it is fitted with the second generation of Dyson Ball technology, makes the DC47 pretty much the easiest 'to use' and 'manoeuvre' cylinder vacuum you can get on the market. Plus, even though it is almost half the size of a standard cylinder it operates at the same level of power -- providing (a rather surprisingly large) 180 Air watts as well as being fitted with the very latest 'two-tier' radial root cyclone technology allowing it to produce even higher centrifugal forces to better 'suck up' even further -- with dust particles as small as 0.5 microns (1000 times smaller than 1 mm).

Note: consideration went to the DC23, DC32 and DC49 (the lightest fo the bunch) but didn't feel that despite them being incredibly light, that they still offered sufficient power and practicalities (like that of the DC47 does) to conduct a thorough cleaning job of your home.

The DC50 is based on a very similar premise to that of the DC47, instead it is just an upright version as well as being an update to the DC24. It weighs in at just 5.4 kg (making it the joint lightest upright vacuum -- with that of the DC24 -- Dyson have made) and is equipped with the second generation Dyson ball, making it as you can imagine incredibly easy to use and manoeuvre (although if you haven't used a Dyson ball before it make take you a short while to get fully used to it). However, where it majorly differs to that of a DC24 is that it still has the suction power (180 Air Watts, two-tier radial root cyclone) to compete (and even surpass in many cases) with that of fully-sized vacuum cleaners. 

Best Overall Value Vacuum Cleaner

The Dyson DC33 Multi-floor

With regards to which vacuum offers you the best 'dollar for quality' vacuum -- I had to weigh it up between several competitiors (incl. DC41, DC40, DC39) but due to the significant reductions and discounts that have been placed on the DC33 -- I believe this is the best Dyson in this respect. Where it offers 255 Air watts of suction power as well as being fitted with root cyclone technology, means in terms of suction performance it is on a similar cleaning standard to that of the DC41 (although not quite on the same level due to the lack of an adjustable cleaning head as well as an older version of RCT). It also offers very decent practicalities -- a bin capacity of 2.3 litres as well as a max reach of 23.5 metres. The only real downside is the lack of mobility and ease of use, given that it operates on a fixed wheeled mechanism (although some may prefer this mechanism) and weighs in at 8 kg.

Best Attachment/Accessory Kit

The Dyson Home Cleaning Kit

I also chose to include which is the Best package of accessories and attachments that you should get for your new/old Dyson and have gone with the classic 'Dyson Home Cleaning kit' (which has the soft dusting brush for cleaning delicate areas, the stubborn dirt brush for helping you to remove dug-in dirt stains within soft flooring and the up-top multi-angle brush for cleaning awkward high and hard to reach areas such as the tops of shelves etc.) for three reasons: i) it offers attachments that are actually very useful and when you have them -- you will actually use them ii) they are compatible with pretty much every Dyson vacuum and iii) getting this package can save you a significant discount.
