This EII control knob replaces a worn, cracked, or missing oven/stove control knob to restore safe, accurate selection of heat settings. It provides a like-for-like interface for turning and selecting temperature or function positions. What it does:

• Fits over the appliance's control shaft to allow manual selection of heat or function settings
• Restores a secure grip and readable pointer for accurate setting adjustment
• Helps resolve symptoms like a loose, spinning, missing, or cosmetically damaged knob
• Re-establishes positive detent feel when the original knob no longer indexes correctly

• Disconnect power to the appliance before attempting service; follow all safety guidelines
• Most knobs pull straight off the control shaft; some models use a small set screw—inspect before removing
• Align the knob's splines/pointer to the shaft and push on firmly (or tighten set screw if present)

This is an electronic brush attachment for a vacuum cleaner, sometimes referred to as a polymatic nozzle. It features a motorized brushroll designed to agitate carpet fibers and loosen dirt for more effective cleaning. Replace this brush if the bristles are worn, the motor no longer spins, or the vacuum is leaving debris behind despite proper suction.
