Rotary sweeping equipment has changed hugely in the past couple of years with fears to damaging liners and power sweeping old steel liners so for this very reason RPS now produce a specialist chimney mole brush that can be used manually and rotary in a flex liner. But as with all rotary sweeping we do not advocate blindly power sweeping upwards into the unknown! We stipulate that the rods must be pushed up manually to ensure that there is no blockage or liner failure and that any loose material dropping down can be inspected. 

 

RPS manufucture the Mini Chimney Mole Brush rotary liner brushes, so if you are wary of using a whip head for rotary cleaning a steel liner, then the Mini Chimney Mole Brush is a great to rotary sweep a liner with a purposely made brush, that will not damage the liner, will not burn your drill out and allow the soot to fall through the bristles whilst rotary sweeping. They come in 4 sizes and are 1/2" oversized to ensure a thorough clean, particularly on a bend.

 

5 1/2" - 140mm, 6 1/2" - 165mm, 7 1/2" - 190mm & 8 1/2" - 215mm

 

RPS developed the Mini Mole Brush over a period of 4 months with various manufacturers liners by highly experienced sweeps. The bristles are the right stiffness and are short in stock for getting round 90 degree bends, plus have a ball end on to protect the liner. The bristles are perfectly spaced to allow soot to fall through them and therefore no undue pressure build up. They are not twisted in a screw effect and likely to grab any loose lining material.

***BE AWARE OF OTHER MANUFACTURERS CLAIMING TO MAKE MOLE BRUSHES, WHEN THEY ARE JUST A MANUAL BRUSH WITH A SHARP TWIST, HEAVY IN COMPARISON AND LIKELY TO DAMAGE A STEEL LINER WHEN SPUN
