When operated conventionally, that is, with the blade bevel-side upward, the drawknife takes deeper cuts and some novices may find it has a tendency to "dive" (cut unintentionally deep).

A vacuum cleaner, also known simply as a vacuum, is a device that uses suction, and often agitation, in order to remove dirt and other debris from carpets, hard floors, and other surfaces. The dirt is collected into a dust bag or a plastic bin.
The bleed port is usually located at the tool end of the vacuum hose, to allow quick adjustment during use. When cleaning is complete, the vacuum hose is removed from the wall inlet (which snaps shut and shuts down the vacuum motor). The hose is coiled up and hung on a storage rack, and any cleaning accessories are stowed away.
