VLM (Very Low Moisture)
Very low moisture cleaning methods for carpet have existed since the 1960’s or probably even earlier by using devices such as a
floor buffer and carpet bonnets to clean carpet with very little moisture. The buffer method works by applying friction (300 rpm),
weight (about 50lbs on carpet area) to transfer dirt from your carpet to wet bonnets.
Historically VLM techniques (we use both the buffer and cylinder method (more on that in another article) have been considered
inferior methods to clean carpet. With the development of modern ecncapsulation (encap) chemicals this is no longer true. In fact
carpet cleaned with VLM hardware and chemicals usually results in equally clean (to a Truck Mount) carpet that dries even faster.
So stay tuned as I will be posting more on carpet cleaning trends and go into detail on VLM and the various hardware methods used.
Currently we use three types of hardware (buffer, orbital, and counter rotating brush) combined with encap cleaning chemicals and
they have worked so well we only keep a few truck mounts around (sold rest) for flood extraction emergencies.
