Compatibility comes first: inclusion is never proof that a model supports your glass or setup.
A window cleaning robot with spray can wet its pad or glass during a pass, reducing stops for manual dampening. Compare how the spray is triggered, which fluid the reservoir accepts, and how the nozzles are cleaned. Automatic application and remote-triggered application are different workflows. Neither tells you whether the robot fits your pane, and more nozzles alone do not establish a better finish.
What a product must document
- Exact product source explicitly confirms an integrated spray system
- Supported fluid and fill instructions are captured
- Nozzle count or spray direction is described only when sourced
- Current model variant is matched to the evidence
Questions readers ask
Is spray better than damp pads alone?
It can reduce manual wetting, but results still depend on soil, pad condition, fluid, route, and glass temperature.
Can any cleaner go in the reservoir?
No. Use only fluid permitted by the exact-model instructions.
