Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to vacuum a rug [title] Find the pile direction of your rug. [step] Woven rugs can either have heavy pile, thin pile, or no pile at all-it's just the density of the vertical fibers protruding from the rug. The direction that those fibers naturally lay is called the pile direction.

Ending1: [substeps] Regardless of the direction or thickness of your rug, you will need to find the length of the fibers you're hoping to vacuum. One range is about 20 feet (91 cm). Ending2: [title] Place the machine on low speed and power it on. [step] Depending on the depth of the room you're dealing with, you'll need to turn on higher speed or power the machine on high to get to the pile direction. Ending3: If your rug has heavy pile, this determines how much dirt and debris you'll need to remove. [substeps] Try using a vacuum to pull dirt off your rug. Ending4: To determine the pile direction, brush your hand along the rug. If you are brushing against the pile, you will feel resistance.
