I bought this to replace a dyson dc07. After five years the dyson had broken and it was my second dyson in about 8 years. Comparing it to the dyson it has some massive advantages but some drawbacks.
It is clear this is a machine to be used for long periods, it is immediately apparent after using it for 20 minutes that you feel you could use it all day. It has great ergonomics and is quiet. This is a massive advantage as it makes cleaning less of a chore. The motorised brush is a revelation and really fluffs up the carpet. It has a thick rubber surround on the head which means no bashing of furniture. The wand is easy to access and simple.
The downsides are it has a bit less suction through the wand than the dyson, it uses bags so there is a long term cost but the main one is that when using the hose it is prone to toppling as the hose connects at the top of the machine rather than the bottom meaning one hand needs to remain on the machine at all times. For this it loses a star.
Other things to note are you get no additional tools with the machine so these will need to be ordered separately and mine only came with one bag so order them as well.
In conclusion a high quality professional item at a consumer price.
