Nice to see the extra long curb feelers, but I'm not so sure about how I feel about that aerodynamic twistoflex brush roll compared to the wooden standard...
We have 2 of the Oreck's with the wooden brush roll. They are amazing vacuums especially for pet hair. The only downside is there's no hose for edging, so you have to bring in 2 vacuums.
The navigator is stair friendly
Filter or consider clogs because it is removing more dry soil than others which causes more dumping.
keeping the brush clean and dry will be beneficial to the motor.
Heavy!?- Suck it up, buttercup.
