The VacuMaid® split canister units are the most unique central vacuums on the market. With the power unit housed separately from the dirt canister, you can place the two in separate locations. It is best that the power unit is placed in a remote location to further reduce any motor noise, and the dirt canister is placed where it is easily accessible. The S3600 unit features two Ametek Lamb 7.2" Premier tangential bypass motors for extreme suction and cleaning power. Split canister systems are especially good for people with pets. With the split system, most of the hair is collected in the bottom can, although some may make their way to the top screen. This screen can easily be cleaned by removing the top lid and wiping away the hair. With bag systems, hair from pets will easily clog the bag, reducing its performance, cleaning ability, and life expectancy. The bottom can feature a plastic liner for clean and easy emptying.
