thats because it shines out of the electrolux internal hose
Michael, I wouldn't even say that. I have yet to find an absolutely perfect vacuum - even my beloved Sebo and Lux 500/Twin Turbo's have their flaws. It's all a matter of balancing out the pro's and con's. For example:
Dyson pro's:
No bags to buy
Full stair stretch hose
Brushroll on/off controls
Good suction
Dyson cons:
Messy to empty
Filters have to be maintained
Poor construction
Expensive to buy
impractical tool setup
poor brushroll
near impossible to clean under low furniture
Sebo pro's:
Not overly expensive if you shop around
Easy to maintain
Easy to take apart (brushroll, handle, tools and replacement parts easilly available
Quick use tools
high filtration level
large capacity bags mean emptying less often
reliable and well made
vacuums flat to the floor for cleaning under low furniture
Brushroll is fantastic for grooming/deep cleaning of the carpet pile
Sebo con's:
X series lack brush controls
cleaner prone to falling over when using the hose on stairs
X seies can sometimes be awkward to manuever
Felix exhaust filter not all that easy to replace.
Overall for me, Dyson has 4 pro's vs 7 cons whereas the Sebo has 8 pro's vs 4 con's.
All about the balance
