Dirty-water tanks need emptying and cleaning even when the mop is washed automatically. Warm stored wastewater can develop odour between cleaning sessions.

Instrument stands, pedalboards and thin cables create a complex route. Protect equipment first and keep automated cleaning to the accessible floor.

Too much moisture is a floor-care issue as well as a cleaning setting. Stop first, especially around timber joints, and identify whether this is high flow or a leak.

Threads, pins and fabric offcuts are poor candidates for unsupervised robot pickup. Prepare the room thoroughly and reserve the robot for ordinary dry floor dust.

A litre figure or weeks-of-use claim cannot predict every household. Debris type, cleaning frequency and odour can matter before the bag is visibly full.
