Query: this vacuum does not clean carpets

This vacuum does not clean standard-pile rugs because the brush doesn't go low enough to reach the top of the rug. This means that lint snagged on top of the rug is not lifted and is not vacuumed up. It also means that the rug is not vibrated so dust and dirt particles lying below the surface of the pile are not freed and are not vacuumed up, either.Whoever designed this piece of junk is either a moron or an undercover saboteur from a rival vacuum cleaner company.Don't buy this thing. It may be great for bare floors and shag rugs, but for cleaning standard rugs and carpets it is useless.
