I love 105

I will be brief because many have already detailed their opinion.
Length of wire: in the standard, for me it is never long enough but it is still larger than my previous vacuum.
Noise: compared to a traditional vacuum cleaner there is no picture but it is not as quiet as far as what we see in the pub. By cons we can see the difference in decibels when using small accessories supplied rather than the suction head "traditional"
The triangular head several complain but me it suits me perfectly. Its triangular shape is I find convenient (can also be because I have a steam mop with the head of the same form), and its thickness is no worse than my old with their rectangular head.
The location of the small accessories: both practical and impractical. Convenient because at hand, not practical because the support is easily defeated and accessories "pop" while using the vacuum cleaner.
Aspiration: nothing wrong with the drive and plenty powerful.
The capacity: quite good, with a dog, a rabbit, a family of 4 in almost 90m², the bag lasts almost three months.

For me, perfect value for money
