Window Cleaning Robot Checklist: Before Every Cleaning Run

1. Confirm this exact job is compatible

Open the exact model manual and confirm the pane type, clear width and height, angle, frame or frameless edge, coating, temperature and indoor or exterior use. Inspect the glass for cracks, looseness, chips, deep seams, decals, condensation, oil and heavy debris. Check the window hardware and make sure an opening sash is stable.

Do not start when a required specification is missing. Mark the job verify first and ask the robot or glass manufacturer. Past success on a different pane is not proof that today's surface and conditions are compatible.

• Exact model and regional manual available
• Clear pane dimensions pass
• Edge and frame type approved
• Surface and coating approved
• Glass and window structure intact

2. Inspect the robot and cleaning system

Check the housing, handle, attachment point, drive surfaces, sensors, spray nozzles and pads. Pads should be clean, correctly fitted and prepared with only the solution amount the manual specifies. Remove grit that could scratch glass. Do not operate a unit with cracks, unusual odor, damaged connectors or a persistent error.

Confirm maintenance intervals and pad orientation. A saturated pad is not extra cleaning power; it may smear or reduce traction. Keep spare clean pads ready for a large or dirty pane rather than extending one pad beyond a useful pass.

• Housing and handle undamaged
• Sensors and drive surfaces clean
• Pads clean and correctly seated
• Approved solution and amount used
• No unresolved alert or fault

3. Verify power and emergency protection

Fully charge the backup battery or station as instructed. Inspect the approved adapter, cable, connectors and strain relief. Connect components completely and keep them dry. Plan enough reach for the entire route without tension, unapproved extensions, pinch points or trip hazards.

Identify the normal-ready signal, low-suction warning, power-loss alarm and physical stop control. Know the exact retrieval steps before attachment. Any published emergency hold time is model- and condition-specific; it is not a cleaning countdown or proof of normal cordless runtime.

• Emergency system fully charged
• Approved power components intact
• Cable reaches without pulling
• Connections dry and protected
• Power-loss procedure understood

4. Set the tether and work zone

Inspect the supplied rope, connector, robot attachment and the exact manual's anchor arrangement. Attach it before placing the robot on glass, route it clear of sharp edges and use only the prescribed slack. Confirm that the selected object cannot move, tip or release under the manual's setup; do not assume that an object approved as an example for one model qualifies for another.

For exterior or elevated glass, clear and control the area below. Keep children, pets, neighbors, pedestrians, vehicles and fragile items away. Postpone the job if that area cannot be controlled or if wind, rain, condensation, frost or temperature falls outside the manual's limits.

• Tether and connector undamaged
• Exact-model anchor method verified
• Rope attached with correct slack
• Area below secured
• Weather dry, calm and within limits

5. Plan placement, supervision and retrieval

Before attachment, identify the documented start point, normal ready signal, full cable and restraint route, continuous supervision position and safe retrieval point. Confirm that changing conditions, people entering the area or an alert can be handled without leaning, climbing or standing below the unit.

Manuals conflict on whether attachment is stopped before or after the unit leaves the glass. Plan to secure the handle and follow the exact model's stop-and-removal order. Do not substitute the sequence from another model or improvise a normal retrieval with its power cord.

• Documented start point is safely reachable
• Normal ready or adhesion signal is known
• Continuous supervision position is planned
• Cord, restraint and retrieval route are clear
• Exact-model stop and removal order is understood

Five decision gates that stop the planned run

Do not begin—or stop and retrieve safely—when compatibility is uncertain, the tether or anchor fails inspection, weather or glass is wet, the work zone below is uncontrolled, or recovery would require leaning or climbing. A convenient cleaning cycle or highly rated robot does not make these conditions safe.

Print or save this checklist near the robot, but update it when the exact manual changes or a new model is purchased. General guidance supports the manual; it never replaces it.

Do I need the checklist for an indoor ground-floor window?

Yes. The consequences may be lower, but glass compatibility, pad condition, power, secure attachment and supervision still matter.

How often should I inspect the tether?

Before every run and after storage, abrasion, impact or any load event, following the manufacturer's replacement rules.

What is the most important reason to postpone cleaning?

Any failed safety gate: uncertain compatibility, damaged equipment or glass, unsafe weather, no manual-compliant stable anchor, uncontrolled space below or unsafe retrieval.
