BEST Cleaning Suction Carpet Nozzle?

[beko1987]

Personally, the original contour head is the best one I've ever had. Better than dysons so called constant head thing

The best?

It'd probably have to be this Vacu-Maid combination tool that came from a Coltrin central vac.... notice the floor/carpet selector pedal on the left.... It has 2 channels for suction and, man, does it clean! It even works great with my Electrolux model XXX, which does have fairly weak suction.
