Dyson DC26 Multi floor canister
The unit's pieces all fit together with precision - no friction fit like some vacs.
Small, light, very good power for its size. Used mostly for hardwoods the floor attachment works nicely.
The attachment uses carbon fibers to help sweep the floor while vacuuming, yet dust doesn't stick to them - nice touch.
For a few Persian rugs, I use the air-driven power head for periodic cleaning which is effective but not aggressive. It is smaller than most, but is handy for getting around and under furniture.
Unfortunately, function followed form with respect to the power cord. It is far is too short - another 5 feet would have made a big difference in usefulness.
Generally, the DC26 lives up to its marketing. It has been well conceived and executed. I bought it new, online for $300 with free shipping, which makes it a good value.
