Aerus Electrolux power nozzles are FAR from fragile. They are famous for taking abuse and keeping on trucking. Their cogged belts are famous for being glass reinforced and for very rarely ever snapping or stretching too. Many manufacturers don't have brushes "right up to the edge" or whatever. Including the global #1 makers, the German manufacturers. It's not necessarily better. It's mostly a gimmick to make people think it's better. Aerus Electrolux engineered high-velocity edge cleaning slots to take care of corners/edges and it works like a charm. Other manufacturers use this method also. The "edges" of carpet don't get walked on and don't have dirt ground in as high traffic areas do and don't need "brushed" as much. Aerus' edge cleaning slots clean from the FRONT and the SIDES of corners where brushes do not. Aerus' light bulbs might be "complicated" but they are known to last for very long periods of time. Most makers of vacuums use chevron pattern brushes too. Results show it's dirt removal to be better. Aerus remains the only maker of a power nozzle that combines commercial 15" size, L-shape, auto height adjustment, wrap around bumper, LED light, circuit breaker protection, chevron double helix brush roll, cogged glass reinforced belts, rug guards, front suction slots, edge cleaning slots, and a steerable, flat-laying design all in an ultra thin design. And now they combine automatic brush speed adjustment and noise reduction. Aerus doesn't need "purists" to defend them. Their record, while flawed like everyone else's, speaks for itself. When you take one or two features, or lack therof, and use it to declare the inferiority of something you have crossed the boundary from debate and criticism to hair-splitting. These last few posts COMPLETELY ruined this thread...
