FLOOR MATERIAL MAINTAINING METHOD, FLOOR MATERIAL RENTING METHOD, HOUSING BASKET, ULTRASONIC CLEANING APPARATUS, AND SYSTEM FOR RENTING FLOOR MATERIAL

摘要

PROBLEM TO BE SOLVED: To efficiently clean stains intruding into a minute flaw formed on a floor material required to be cleaned, recover the fine appearance similar to that of a new floor material and reuse the cleaned floor material as the floor material to be rented. SOLUTION: The laid floor material is recovered (S3) and housed (S5) in a housing basket. The recovered floor material is cleaned (S11) ultrasonically by using an ultrasonic cleaning apparatus using the housing basket as an inner basket. The cleaned floor material is rinsed (S13), dried (S15) and subjected to coating work (S17) to recover the fine appearance similar to that of the new floor material and then rented again (S22).
