Window robot calculator: panel fit and manual moves
A robot can travel across a pane, but a person still organises the job. Suction figures and minutes per square metre are only part of the buying decision. The smallest unobstructed panel, access to the outer side, cable reach and a suitable securing point can matter more in daily use.
This calculator combines dimensional selection with a count of manual handling. Enter groups of differently sized panels, their quantities and one or two sides. It reports placements, moves between surfaces and glass area. It does not turn these inputs into an invented time-saving claim.

How much work will your windows still need?
Count separate glass panels, check their size and see the manual moves required. The robot does not transfer itself to another pane or the other side.

ECOVACS WINBOT W3 OMNI
OMNI bundle with station and 2-in-1 cable. Check the manual for the regional variant.
Open model profile →HOBOT S7 Pro
The manufacturer specifies >50 × 50 cm, not ≥50 × 50 cm. Prepare the power supply and tether.
Open model profile →Dreame C1 Station
C1 Station GCJZ2419 manual, p. 17: maximum 400 cm width and 250 cm height per side; 5.5 m station cable. Minimum for the exact variant is unconfirmed.
Open model profile →HOBOT SP10 iScraper
The official table specifies width >40 cm. It does not state a minimum height here; we do not turn this into a 40 × 40 cm claim.
Open model profile →How to read the result?
Fits dimensionally means the entered measurements match, not that the product was tested. Conditional requires a further check. Rejected identifies a mismatch or unsafe setup. Missing data is not a pass. A two-step claim never becomes a single-edge limit.

One window can create many separate tasks
Eight identical panels cleaned on both sides mean 16 placements and 15 moves between successive surfaces. These are geometric minimums: they exclude restarting after an error or an additional pass. The initial placement is not a transfer from a previous pane; the robot must also be removed after the last cycle.
Raised muntins divide the working surface. Muntins sealed inside a glazing unit generally do not obstruct its outer surface. Measure the area the robot will travel across, not the entire sash including its frame. Do not assume that the machine can cross raised strips.
A minimum size is a requirement, not a cleaning guarantee
The official German WINBOT W3 OMNI listing specifies a minimum of 30 × 40 cm. HOBOT specifies >50 × 50 cm for S7 Pro. The greater-than sign matters: a panel exactly 50 × 50 cm does not meet that wording. An unconfirmed number for a specific variant is labelled as missing evidence.
A suitable size does not establish sealing, glass condition, slip resistance, cleaning-solution compatibility or edge-cleaning performance. This method does not qualify damaged glass, unknown surfaces or unusual inclinations. The exact version’s manual defines the final operating conditions.
The outside face needs a separate decision
Confirm safe access, the anchor and the securing arrangement required by the manufacturer. Check cable reach, weather and the area below the window. Without those conditions we do not recommend starting, even on a sufficiently large pane. Do not lean out to place or retrieve the robot.
What should you compare after shortlisting?
Count pad handling, filling and emptying, side changes and finishing work. Try one safely accessible pane first. Record machine-running time separately from your active handling time. That is the basis for deciding whether this workflow suits your home.
