Self seeking neutralling arrangement for a power assisted cleaner |
摘要 |
A power assisted vacuum cleaner is provided with a hand grip neutralling arrangement which is self seeking or presettable to provide a neutral position for the actuating linkage of the cleaner. A neutralling spring constantly urges a neutralling pin towards neutralling position and it is freed by movement of a manually operated button to seek this position.
