The cleaning performance of the vacuum cleaner is reduced (Boost CX1).
Something bulky has been vacuumed up (e.g. large leaves from house plants) and is blocking the suction tube. The casing gets very hot as air is unable to escape as required.
Disassemble the floorhead, hose, handle and telescopic tube.
You can carefully push large items which are jammed in the hose or in the telescopic tube towards the floorhead using a long object (e.g. a broom handle).
Items causing a blockage are usually easy to shake out of the handle.
