I am wondering if you guys have had a chance to check out the sebo evolution.
By the looks of it its a single motor unit like the x series and G series.
I have mixd feelings about two of its features I have seen so far.
The easily replaceable brush strip, This is great from a maintenance and ownership point of view, Those brush strips are cheap and easy to replace.
That said if you have ever used a G series or x4 over a area that was vacuumed by a 360/370 or bs36 you will see the x4 leaves the carpet more groomed and lifts more dirt out , This is because of its double brushed brush bar. It has two rows of brushes on either side of the bar , the brush strip only has one that wraps around the brush bar. Basically in one revolution of the brush bar the carpet is only getting brushed once on a unit with the brush strip but twice with the g or x series.
The easily changeable cord, Idea great if the cord breaks you can easily change it on the move or just order a new one and fit it yourself.
Not so great is that when the machine does come in you have to sell the customer a £ 60.00 cord instead of just cutting a small piece ( they always break at the same point ) off and re fitting it or fitting a standard electrical cord.
Other than those points it looks interesting, Cant wait to try one
