Flexible Flue Liner Clearing Kit
The Smart Sweep Flex provides a novel method of cleaning flexible chimney flue liners of diameters up to 150mm (6"). The Kit is designed to be used primarily by DIY residential and light commercial operators.
The unique system, which incorporates 10mm diameter POM rods, has demonstrated that the flail head is able to pass through changes of direction of 45° bend in a 125mm (5") flexible liner, a procedure not possible with conventional 125mm (5") flexible liner cane rods!

What comes in the Smartsweep Flex Kit
10 x 1.00 metre POM rods There are ten rods supplied with this kit – providing sufficient assembly to remove removes deposits of soot and fly ash from a ten metre flexible flue liner. All rods are very strong and flexible, made from 10mm diameter solid POM.
1 Drill Adaptor The Drill Adaptor should be used in a conventional drill chuck. Drills should be set without hammer action.
1 Flail Head with 8 Flails The Flail Head is designed to remove loose soot particles and fly ash from the walls of the flue liner.
1 Bristle Head The bristle head is connected to the rods using an identical coupling system as the rods themselves, does not require rotation and is simply pushed using the hand grip.
1 Hand Grip Designed to be used with the bristle head when cleaning the flexible flue liner without the power drill.
How to use the Smartsweep Flex
Once connected to a POM rod, the flail head is inserted into the flexible flue liner and the other end of the rod is "snapped" onto the drill adaptor. As the flail advances, more rods are applied in the same way. The flails have a diameter of 300mm (12") and are designed to distort as the head is pushed into the flexible flue liner.
Because the connected rods use joints incorporating a flat section, the drill action can be set to forward or reverse which can be an advantage where stubborn soot or fly ash deposits are encountered. The flails are tightly clamped within the head by use of a grub screw located in the cap which, when tightened, applies a firm pressure to the assembly.
The bristle head does not require rotation and is simply pushed using the hand grip. It can be used with as many rods as are necessary to brush the entire flexible flue.
Connection of the rods is achieved using special plastic male and female couplings. Unlike some conventional sweeping rods, the Smart Sweep Flex couplings do not rely on screw threads to make the connection and so can be rotated in either a clockwise or anti-clockwise direction. The couplings contain flat sections to transmit rotational torque and spring clips to prevent them from separating. When required, the couplings can be separated by pressing in the spring clip button and pulling the couplings apart. The connection details of the male and female couplings are replicated in the operating heads and the adaptor for the cordless power drill.
If Flails need to be replaced, the grub screw in the top of the dome is loosened. The existing flails can be withdrawn. Two new sets of 300mm long flails are inserted from each direction and cross over in the middle of the head so that about 130mm projects from each quarter of the head surface. Once the flails are correctly located and with the steel disc correctly located, the grub = screw is fully tightened. As the grub screw is secured it applies pressure onto the steel disc and ensures that the two lower sections of the flail head are forced apart by the captured flails and locks them in position.
Connecting the rods, heads or drill adaptor
To connect two rods, align the flat sections and the button of the two halves, depress the Spring Clip Button and push the sections together until the button snaps out indicating a secure joint.
Separating the rods, heads or drill adaptor
To separate the connectors, firmly depress the button and the two halves can be parted. The Flail Head and the Plunger Head are both designed to be "snapped" onto the Male end of a Rod and the Drill Adaptor snaps into the female end of a rod.
