Using the correct Vacuum is essential to keeping your carpet looking like new.
It is absolutely vital that a vacuum cleaner with a power head is used for all plush pile carpets, without this the vacuum will not be sufficient to: (a) remove the loose dirt that has made its way into the pile (b) bring the cut pile back to its upright position. The preferred type are the upright models such as a Dyson, Karcher and it must have a separate motor driving the turbo head as opposed to the suction based types.
The ducted vacuum systems without a power head attachment will not work under any circumstances, most ducted vacuum cleaner suppliers offer turbo head attachments, however these do not have a separate motor to drive the power head, they rely totally on the suction to function. If the motor in the system is not strong enough it will not provide sufficient power to the attachment to function adequately .
We have formed the view that it is not worth going to the expense of purchasing the top of the range in these systems and then purchasing an attachment which is still only power driven. We advise our clients to use the ducted system for the hard floors and purchase a decent vacuum cleaner such as a Dyson or Karcher with a power head driven by separate motor, not suction driven for their carpet areas. These are approximately $700 – $800 which is far less than you would spend on an upgraded ducted system and an attachment.
