Vacuum symptom guide

Why Is My Wet-Cleaning Vacuum Leaking?

A liquid leak means water or cleaning solution is escaping where it should remain contained. The source may be a clean-water tank, recovery container, cap, valve, hose, roller chamber, seal, or onboard liquid path, and it must be located before any part is chosen.

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 disconnect the machine

Turn the machine off and disconnect it from power before handling a leak. Do not energize a wet machine when liquid can reach its battery, motor, charger, dock power connection, or control housing.

Safe first checks

  • Empty and reseat owner-removable tanks, caps, trays, and rollers using the exact model instructions.
  • Inspect visible seals, valves, tank seams, and removable wet-capable hoses without opening an electrical housing.
  • Keep recovered liquid away from the battery, charger, motor, dock power input, and electrical contacts.

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 the liquid is clean solution, dirty recovery water, or an unknown spill
  • Whether it appears while filling, parked, dispensing, scrubbing, or recovering water
  • The exact tank, cap, valve, hose, roller chamber, dock, or body seam where it first appears
  • Whether a tank is cracked, overfilled, incorrectly seated, or missing a visible seal

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.
