Families with low sofas or beds
If reaching dust beneath furniture is the main goal, measure each intended gap before comparing other features. Roborock and eufy publish different clearance figures for their named models.
Who needs under-furniture cleaning?
Busy households with floor clutter
Scheduled runs around cords, socks and toys call for both suitable obstacle handling and a habit of clearing the floor. Object recognition does not replace preparation.
Households balancing floors and upkeep
Where hard floors, rugs or carpet share a home, check how a vacuum-and-mop model handles each surface. A maintenance dock may reduce some routine handling, but it also needs space and care.
What matters when choosing?
Start with the tightest gap the robot must enter. If a model can reach it, consider household clutter, floor types and charging arrangements before choosing its other features.
| Concern | What to check | Who this matters to |
|---|---|---|
| Furniture clearance | Measure the lowest usable gap, including rails and uneven flooring. Compare it with the exact model’s stated access requirement, not just its body height. | If dust collects beneath my low sofa, reaching that space matters more than extra dock features. Roughly 46% of consumers put under-furniture access first. |
| Floor clutter | Check which objects the model claims to recognise, and keep cables and loose items out of its path before scheduled runs. | When the family leaves socks or toys on the floor, I want fewer interrupted runs without relying on detection alone. Around 27% of consumers prioritise clutter handling. |
| Mixed floors and upkeep | Check mop behaviour around carpet and what the supplied dock empties or washes; allow for dock space and compatible replacement supplies. | If I have both hard floors and carpet, I want mopping and routine maintenance to fit the way I clean each surface. About 18% of consumers make mixed-floor use and upkeep their primary concern. |
| Charging safety | Confirm the charger or base has a UK three-pin plug, and use the supplied charger or a replacement confirmed as compatible. | Because the robot will charge at home, I want confidence in its power parts and where replacements come from. Roughly 9% of consumers place safe charging and ongoing ownership first. |
Mistakes to avoid
-
Choosing by robot height alone
A slim body does not guarantee entry. eufy specifies at least 10.2 cm of furniture clearance for its 9.60 cm S1/S1 Pro, while Roborock cautions that Saros 20 may scrape when entering a tight gap.
Measure the narrowest usable space, compare it with the exact model’s access requirement and supervise initial runs near tight furniture.
If the robot cannot reach the intended space, that area will still need manual cleaning.
-
Using suction figures as a cleaning score
iRobot cautions that suction alone does not determine cleaning performance; brushes, debris type and the air path also matter.
Consider the flooring, brush design, navigation and furniture access alongside any stated suction figure.
-
Leaving cables out because the robot avoids objects
Object-recognition claims are model-specific. Electrical Safety First advises keeping wires and cables out of a robot vacuum’s way.
Pick up cables and small loose items before scheduled cleaning, even if the model advertises obstacle recognition.
-
Using an unsuitable charger or uncertain replacement parts
Electrical Safety First warns that second-hand batteries and chargers can present a serious fire risk.
Check for a UK three-pin plug and use the supplied charger or a compatible replacement from the manufacturer or a reputable supplier.
Relevant brands to consider
Roborock
Relevant when a measured furniture gap makes low-clearance access the deciding factor. Roborock states that Saros 20 can navigate spaces down to 7.95 cm; it lists Saros 10 with a 7.98 cm body.
- Roborock describes slim-body access and, for Saros 20, adaptive threshold crossing and anti-tangle features.
- Roborock cautions that entry into tight spaces may involve scraping and that actual access varies with the environment.
eufy
Relevant to households considering a vacuum-and-mop system with an automated station, provided their furniture has enough clearance for the chosen model.
- eufy specifies a 9.60 cm height and at least 10.2 cm of furniture clearance for S1/S1 Pro, giving buyers a model-specific figure to check.
- eufy warns that uneven, dark or reflective furniture undersides can affect height sensing.
iRobot
Relevant when handling floor obstacles and reducing routine dock tasks matter, after confirming that the chosen robot fits beneath the furniture.
- iRobot says the Roomba Plus 505 Combo recognises cords, socks and pet waste; its dock empties debris and washes and dries mop pads.
- iRobot cautions that suction figures alone do not establish cleaning performance. The named model’s furniture access and suitability for each floor still need checking.

Frequently asked questions
How much space does a robot vacuum need beneath furniture?
Use the clearance requirement for the exact model rather than a general height rule. Roborock states that Saros 20 can navigate spaces down to 7.95 cm, while eufy requires at least 10.2 cm for S1/S1 Pro. Measure the lowest point, including rails and uneven areas.
Can a robot still get stuck if the measured gap looks high enough?
It can, depending on the furniture and floor. eufy warns that uneven, dark or reflective undersides can affect S1/S1 Pro height sensing, while Roborock cautions that Saros 20 may scrape in tight spaces. Supervise the first runs around furniture that leaves little room.
Should I clear the floor before a scheduled run?
Yes: move cables and loose items out of the robot’s path. Electrical Safety First advises keeping wires and cables clear, even when a model advertises obstacle recognition.
What should I check about a robot vacuum’s charger?
Check that the charger or base has a UK three-pin plug and use the supplied charger or a confirmed compatible replacement. Electrical Safety First also warns about the risks of second-hand batteries and chargers.
