Vacuum symptom guide
Why Is My Wet Cleaner Not Moving Water?
No liquid flow means the machine does not dispense, hydrate, collect, or recover water as designed; it is different from liquid escaping onto the floor or into the housing. Tank seating, valves, onboard tubing, pumps, wet rollers, recovery paths, sensors, and controls can each stop flow.
Important distinction
A symptom is not a repair diagnosis
The same symptom can come from several assemblies. Use the evidence below to choose a repair path, then confirm the failed part and exact model compatibility before ordering.
Safety first
Stop and inspect before using it again
Stop and disconnect the machine if a pump runs dry, a roller drive stalls, an error repeats, or liquid appears near electrical parts. Do not prime a pump or bypass a tank sensor unless the exact owner guide permits it.
Safe first checks
- Fill, close, and reseat only the documented tank with the permitted water or solution and correct fill level.
- Clean owner-accessible valves, channels, trays, and wet rollers using the exact model procedure.
- Do not open a pump, powered wet head, battery housing, control board, robot, or dock enclosure.
Narrow the cause
What to observe before choosing a repair
Record these details without bypassing an interlock or opening a sealed electrical assembly. They help distinguish repair targets that can produce a similar symptom.
- Whether clean water fails to dispense, dirty water fails to recover, or both functions stop
- Whether the tank empties, the roller becomes evenly wet, or liquid remains trapped in one path
- Any exact flow, tank, pump, roller, or recovery error shown by the machine
- Whether the problem began after storage, cleaning solution residue, scale, a jam, or tank removal
Possible repair paths
Repairs that can fit this symptom
These are possibilities, not a definitive diagnosis. Select the repair whose evidence fits the exact machine and behavior.
Repair intake
Still not sure which repair fits?
Start with the make, exact model, photos, and what the vacuum is doing. Inspection confirms the failed assembly before final parts or repair decisions.
