Nap-surface cleaning with tuned frequency beaters |
| abstract |
A nap-surface cleaning device includes a plurality of flexible rodlike beaters which oscillate to beat the surface and loosen dirt embedded therein. A motor drives the rods at a beating frequency. The rods are constructed so that their natural resonant frequency is closed correlated with the beating frequency. |
