AI Technical Summary

Benefits of technology

"The invention is about a surface cleaning apparatus that uses magnetic attraction to securely attach different components together. This eliminates the need for mechanical engagement members that can break easily during assembly and disassembly. The apparatus includes a cyclone chamber and a material collection chamber that are magnetically secured together. The magnetic seal is formed without the need for an O-ring or gasket, making it reliable and easy to seal. The apparatus also includes a pliable magnet and a magnetically attractable member to secure the components together. The magnetic seal can be easily formed without the need for precise alignment. The technical effects of this invention include improved sealing, reduced assembly and disassembly time, and increased reliability of the surface cleaning apparatus."

Problems solved by technology

Such parts, which are typically plastic molded parts, have a tendency to break during repeated assembly and disassembly of parts.
