I have a copy of the Dyson DC27 leaflet. I have read this a few times. I have no intention of buying the DC27 as I have a functional DC04 which I'm happy with. The DC27 states in the first page that Dyson engineers are seeking improvment etc etc.
They mention that their manifold 'fingers' have been re-engineered for improved airflow and separation efficiency. This makes the DC27 much more advanced than their previous machines, the suction on the DC27 I might point out is less than the DC14 which has the same motor wattage and a lot less compared to the UK DC07. I do not see any improvment here.
The brochure also states that the head creates a tight seal and that the head adjusts and the brushbar articulates for constant contact with the floor. This is nothing new, my 7 year old has a self adjusting head with the brusgbar area that moves about to keep close contact with the floor and believe me it does work as my machine is so hard to push on lino and the carpets upstairs as the head is sucked so hard onto the floor.
The brochure syays prolonged filter life from Root Cyclone - I'm not sure about this one as my DC04 doesn't neet its filter washing for at least 6 months where as the DC27 like the newer Dysons says that the filter is to be washed every 3 months.
The tools are def not an improvment, I do not like the combined brush/crevice tool, My DC04 has a big brush tool, long crevice tool and articulating stair tool, the DC27 stair tool does not articulate to get into angles.
The bin capacity is still small and the shroud is massive!! The brochure states, new shroud perforations to prevent hair and fibres becoming trapped but I do not encounter this problem with my existing 'old' DC04, the only time I have this is when I overfill the bin right up to the top, the bin capacity on my DC04 is 4 litres the DC27 is only 2.3 litres.
I have to say that the only thing I personally think is improved is that the plastic is better grade - more flexable where as the older ones used to be so brittle and break, so many parts have broken on my DC04 but the main parts like the motor, clutch etc have gone on and on.
