Compare your actual furniture route with the complete robot’s dimensions and instructions. There is no universal robot height or spare-clearance rule that proves every sofa or bed is accessible.
This guide provides a measurement worksheet. It does not claim that we tested navigation, cleaning performance or fit for a particular robot.
Read the height and width results separately
Use the calculator above with the lowest gap on the complete route. Enter the complete operating height, including the highest sensor and attached components, then your chosen reserve for the actual floor and instructions. A nominal body measurement is optional context; it never replaces an unknown complete height. Unknown reserves also stay unknown rather than becoming zero.
The starting example has a 95 mm gap, 98 mm complete robot height and an 85 mm body. The robot is already 3 mm taller than the opening before any extra reserve. The smaller body number cannot reverse that result. These are illustrative measurements, not a named product or an installation test.
The eufy Omni E25 T2353 User Guide, PDF page 14, lists robot dimensions of 346 × 327 × 111 mm. The manufacturer’s E25/E28 dimension support page separately lists 111.3 mm robot height for both models. The reference action uses the larger stated 111.3 mm figure for arithmetic, while leaving body, width and chosen reserves unfilled. Both sources were checked October 16, 2026. These are published figures, not our physical measurements or a guaranteed tolerance; confirm the exact configuration and route rather than rounding a close fit down to 111 mm. Its official support page identifies the exact T2353 guide. Confirm the configuration and current instructions before using any model dimension.
Entry width is a separate calculation: clear width minus the complete robot width in the intended orientation, minus the reserve at each side. A positive height result cannot resolve missing width measurements or prove there is room to turn around a center support. Zero spare is an exact arithmetic boundary with no extra tolerance. Download or print both checks with their actual inputs and unresolved fields; the diagram is a comparison of heights, not a navigation simulation.
Measure entry, interior and exit
Record the lowest opening along the intended route, including front rails, crossbars and center supports. Measure where the robot would travel, not only the largest visible gap. Include floor changes, rug edges, hanging fabric and obstructions.
Record width and turning space as well as height. A robot that passes through an opening may still have no workable route around a support or out of the space. Avoid relying on contact with the furniture to discover the fit.
Use the tallest part of the actual model
Check the complete operating height, including sensors and attached components. Product photographs and a nominal body height can omit the part that controls clearance. Do not remove a sensor or alter the robot to make it fit.
iRobot’s navigation guidance notes that a top-mounted LiDAR sensor on the models it discusses adds height that can affect access under furniture. That example shows why model-specific dimensions matter; it does not establish a dimension for every robot or brand.
Leave the clearance required by the manufacturer and account for the actual route’s variation. If dimensions or permitted clearance are unclear, ask the maker before buying. A universal half-inch allowance is not a substitute for the instructions.
Complete the room worksheet
| Record | Check against the exact model |
|---|---|
| Lowest route height | Complete operating height and permitted clearance |
| Entry width and interior layout | Body width, supports and space to navigate |
| Floor and thresholds | Supported surfaces and crossing limits |
| Hanging fabric and cords | Preparations required before a run |
| Navigation conditions | Lighting or other environmental requirements |
| Dock location | Power, access and the specified clear area |
| Service access | Bin, brushes, filters and permitted mop care |
Dock sizes for current self-cleaning models are listed on the self-cleaning robot vacuum page; leave room to open the lid and lift the tanks.
Dock placement is a separate check. A small robot can come with a larger station whose access and installation requirements determine whether the room works. Use the instructions for that station, not another model’s distances.
Include costs and maintenance after fit is established
Compare the complete purchase price with the accessories and recurring consumables you actually need. Check availability of compatible filters, brushes, bags and any supported mop parts. A budget label or a larger feature list cannot establish good value when the robot cannot reach the intended area.
For a wet-cleaning plan, check the floor-care document finder separately. Physical fit does not establish permission for the actual finish, method or cleaner.
After checking physical fit, use the running cost calculator to compare your purchase price and recurring supplies without inventing a service life.
Follow the cleaning and maintenance instructions, including what must be dry before reuse. Confirm navigation settings and floor restrictions rather than assuming all camera systems, mops or no-go zones behave alike.
If the route cannot meet the exact instructions, compare a suitable manual cleaning tool for that space. Do not change load-bearing furniture or bypass device safeguards to justify the purchase. Fit is a documented comparison to perform before spending, and successful navigation still needs to be observed after correct setup.
