Dyson DC23 Vs DC39
If you are wanting to know the primary differences between the two Dyson canister vacuums -- the DC23 and the DC39 -- then you are in the right place. Below, is a brief & objective comparison account highlighting both their similarities & variations within specifications & features -- ultimately determining which of the two is best suited to your preferences & needs as well as which one provides you with the most 'overall' value (respective to its price tag).
DC23: Constant Cleaning Suction Power -- 220 Air Watts
DC39: Constant Cleaning Suction Power -- 280 Air Watts
As seen from the specs the DC39 encompasses a total of '60 air watts' more cleaning power than that of the DC23 (which although isn't the only indicator of cleaning performance, it is a strong one) & along with its more advanced 'trigger head' & articulating floor tool (& fitted technology, more on that just below), means the overall cleaned finish on all floor types (incl. rugs etc.) is superior to that of the DC23. That being said, the DC23 doesn't do a bad job by any means (better than most standard canister vacuums), but it is just the simple fact it is being compared with Dyson's current 'all singing & all dancing' canister vacuum that produces an excellent cleaned finish.

DC23: Root Cyclone Technology (level 3)
DC39: Radial Root Cyclone Technology
Both are fitted with the unique Dyson Root cyclone technology -- only that the DC39 is fitted with a more advanced (radial) version. This basically implies three main benefits: they can operate on a bagless mechanism (hence saving you the running cost of replacing bags as well as being able to tell when the bin needs emptying -- due to its transparent container), they don't suffer with loss of suction (like many other non-Dyson vacuums as they build up more & more dirt -- the suction level diminishes, however not so with the Dyson vacuums) and finally -- and where the difference comes in -- is that they can generate high centrifugal forces to suck up microscopic particles (the difference being the DC39 can produce even higher centrifugal forces & hence has an even greater pick up of even smaller dust particles).

Manoeuvrability & Mobility
DC23: Canister Vacuum. Wheeled Mechanism. Weight: 8.8 kg
DC39: Canister Vacuum. Dyson Ball. Weight: 7.5 kg.
The DC23 and DC39 are obviously canister based vacuums (so hopefully that is your preferred vacuum type -- rather than an upright ). But, as you can see from the listed info, the DC39 edges it with regards to being more agile and easier to manouevre -- due to two important factors: it is lighter (by 1.3 kg) but more importantly the DC39 is fitted with the Dyson ball mechanism that allows it turn on a singular dime (whereas the 'rigid' wheel mechanism for the DC23 makes it a bit more of a struggle to get around awkward corners & gaps, having to drag it back and forth etc.).
DC23: Size -H: 35.3 x W: 49.0 x D: 30.2 cm. Cord: 6.58 m. Reach: 11.03 m. Bin: 2 litres.
DC39: Size H: 50.7 x W: 36.8 x D: 26.1 cm. Cord: 6.5 metres. Reach: 10 metres. Bin: 2 litres.
Clearly, both machines are intended for the 'medium' to 'larger' home (as well as it becoming increasingly clear that the DC39 is an 'upgrade' to that of the DC23) with an extensive max reach (DC23: 17.61 metres, DC39: 16.5 metres) and bin capacity (both at 2 litres). Moreover, you can see that the DC39 is the more compact of the two vacuums as well (hence better for storage) and has also had acoustic engineering to lower noise & improve sound quality produced.
DC23: Combination Tool. Stair Tool.
DC39: Combination Tool. Stair Tool. (Tangle Free Turbine Tool)
Both canister vacuums are provided with the standard Dyson tool kit -- the combination tool (which is basically just a crevice tool - which is for used for cleaning awkward & tight gaps etc. -- that has the ability to double up as a brush nozzle to allow for powered dusting) as well as a stair tool. Moreover, if you get the Animal version of the DC23 or DC39 (i.e the DC23 Animal & DC39 Animal) you also get a specialised pet hair turbine that has been specially designed for efficient pet hair pick pick up -- the DC23 gets: the mini pet hair turbine tool -- whereas the DC39 gets the more advanced: tangle free turbine tool.
With regards to the warranty, they are both backed by a stellar five year guarantee for both parts & labour (when bought new) -- so you are entitled to get it 'fixed' like new at zero cost if any thing potentially went wrong. In regards to the filtration system the they are fitted with a HEPA filter that prevents allergens & dust particles from being expelled into the air and hence are safe to be used by asthmatics & allergy sufferers.
Conclusion: Should You Buy the Dyson DC23 or DC39?
Both models of the canister have a similar target market in mind -- a family vacuum for the mid to larger sized home with various floor types & hence needs to be powerful & posess appropriate practical specifications (hence extensive max reach & bin capacity etc.)-- and both models certainly tick those boxes. However, it is clear the DC39 is the superior model of the two -- for instance it is more powerful, better equipped, easier to store away, easier to manoeuvre etc. With all these improvements -- they come at a price though, you will see that the DC39 is that bit more expensive than the DC23 and it is here where your preferences come in -- are all the benefits worth that difference in price between the two? I would argue, on the average 'yes' -- as you really are getting a top notch vacuum with the DC39 & it does offer you 'so' much more than the DC23 can.
But, please do let me know which one you would opt for and why?
