This test method is based upon results of home cleaningtests so that, in most cases, a reasonable correlation existsbetween ho
17、me and laboratory results. The amount of dirtpicked up in the laboratory test may not be the same as in thehome; however, it will show that, in most cases, a vacuumcleaner that performs well in the laboratory will perform wellin a home. Laboratory results may differ due to variations inthe homes, ca
