Why do Clarke CAV 50 motors increase in RPM?
- MMelissa PowellAug 12, 2025
The vacuum cleaner motors may increase in RPM due to a clogged primary filter or a clogged vacuum hose. If the filter is clogged, use the filter shaker (on models with a manual filter shaker) or replace the filter if shaking isn't sufficient. If the vacuum hose is clogged, inspect the hose and clean it to remove any blockages.
