Vaccume: Carpeted stairs. If you have carpeted stairs, you should consider the weight and style of your vacuum. Climbing a staircase with a heavy upright vacuum can be dangerous. Even a large canister that doesn’t fit on an individual step can fall down the stairs and do some real damage. Therefore, a lightweight vacuum or broom vac is ideal for carpeted stairs.
Wood floors. Wood floors look beautiful, but the space between each plank is a magnet for collecting dust and dirt. To clean down inside those crevices, you will need a vacuum with very strong suction. Suction is measured by water lift. Most manufacturers have that rating on the vacuum itself. You want to look for a rating of over 100 air-watts to ensure good suction. Wood floors are best cleaned with a high-quality canister vacuum with a horsehair floor brush to limit scratches. Some canisters have power heads that can be turned off with a flip of a switch so you can go directly from carpet to hard floors.
