One reviewer liked the compact powered-head configuration as a neat option for stairs.
Pros: Overall opinion, Weight
Cons: Suction and Airflow
Stair suitability was limited by weight, despite Lift-Away making lifted use more manageable.
Pros: Hard Floor — Fine Dust Pickup, Overall opinion
Cons: Weight, Noise level
Stair handling is weak because carrying the unit upstairs feels cumbersome.

Cons: Price and Value, Emptying and Mess Control
Stair use is a poor fit for some homes because the weight and setup made multiple flights difficult.
