Hi I'm new to the forum, Im an avid Dyson fan and have had my DC07 for at least 15 years. Until now I have managed to set any issues but at the moment I am experiencing suction issues in the upright position. The brush appears to be spinning correctly but in order to pick up bits on the carpet I need to pull back the hoover slowly for the brush to take them up. I have removed and cleaned the housing and brush, cleaned all the filters and checked for holes in the hose. The hose suction is fine with accessories so Im assuming it's more to do with the brush, any ideas please?
