Appliance help
A vacuum is a fan (the motor) pulling air through a hose, filters, and a bag or bin. Loss of suction is almost always a full bin, a choked filter, or a blockage in the wand — not a “dead motor” — until those are cleared. Cordless models add a battery that can look like a motor fault when it is just empty or tired.
Reading this page does not start a chat. If you already have a diagnosis in progress, we will ask before replacing it.
Short, honest explanations — not a parts catalogue. If it matches what you are seeing, you can take that wording into a diagnosis.
Work from the head back: clogged floor tool, blocked wand (a sock or Lego is a classic), full bag or bin, and filters packed with dust. A machine that sucks strongly at the hose inlet but not at the head has a blockage in the tools, not a new motor.
Many motors have a thermal cut-out. A blocked machine runs hot and stops, then works again when cool. That is a blockage reminder, not a random electrical ghost. If it cuts out with a clean path, stop using it.
Hair around the roller, a belt (on some uprights), or a clutch that disengages on a stuck bar. Cut hair out with scissors, unplugged. Do not keep running a jammed brush motor.
Mains: check the socket with a lamp. Cordless: charge status and a flashing battery mean power, not floorhead. A completely dead cordless after a drop can be a battery pack or a broken switch — still not something to prize open if the pack is swollen.
Unplug / isolate. A dust-packed motor or a dying armature smells of hot electrics. Do not “just finish the stairs”.
Switch the appliance off at the wall first unless the check is only looking at a display. Stop if anything in Stop and get help applies.
Empty the bin or replace the bag before anything clever. Wash only filters that the maker says are washable — some HEPA filters are dry-clean only and die if soaked. Dry washable filters fully before refitting or you will cook them.
Drop a coin or look through the wand. Flexible hoses crush internally; a hose that looks open can still be blocked inside the corrugations.
Unplug. Cut hair off the roller. Check the suction inlet in the head is not taped over with a rug fringe.
These are the points where another cycle, another click, or a screwdriver makes things worse. ApplianceClinic is not a repair company and will not send an engineer to you.
Do not charge it. Do not put it in household rubbish. Follow local battery disposal. A puffed pack is not a “keep using until it dies” part.
Stop. That is not a filter.
A dry vacuum that has sucked water is an electrical risk. Do not switch it back on to “dry it out”.
Names you may hear in a diagnosis, in plain language. This is identification, not a strip-down guide.
The only moving part that makes vacuum. It fails, but far less often than blockages. Replacing it varies wildly by brand and is often uneconomic on cheap cylinder vacs.
Protect the motor. A missing filter is how motors die young.
On cordless, a pack that holds seconds of charge is a wear part. It is not the same as a blocked head.
A burnt, slack belt stops the brush. Visible once the sole plate is off — only if your model is meant to be opened that way.
Look on the underside of the head, on the motor housing, or near where the hose enters the cylinder. Cordless sticks often hide the model in the battery well or on the wand.
When you start a diagnosis, use the camera button on the composer to photograph the plate. Conversations stay in your browser — they are not published as web pages.
UK Office for Product Safety and Standards notices that may affect vacuum cleaners. ApplianceClinic does not issue recalls — check the official record before you act.
