Its a tie between my Aerus Guardian Platinum and my Tri-Star CS. But, I like to use the same power nozzle on both which is the Tri-Star version with a genuine Lux brush roll that came with the Lux 6000 upright retrofitted. It is the version with the lime green nylon brush strips that are arguably the best grooming on any type of carpet even berber. Why Lux/Aerus stopped making this brush roll....I'll never understand.
The suction on both vacuums is superb and the filtration, IMO, is even better than on the last version of the Air-Way tank which was incredible. [this post was last edited: 8/25/2020-22:32]
