Liectroux N7S-U (robot vacuum cleaner): our review

Crumbs beneath the dining chairs are annoying enough without turning every afternoon snack into another household job. The Liectroux N7S-U advertises suction of 4000 Pa, around the current average. That gives it a sensible starting point for routine vacuuming, but manufacturers measure suction differently, so the figure cannot promise clean carpet.

Is the sitting room rug where your dog's hair seems to settle permanently? We would keep expectations measured. Suction pressure says less about removing embedded hair than you might hope.

We like its everyday purpose. Fewer crumbs waiting when you return from work would make a useful difference. Our overall assessment places this robot favourably, with the practical demands of emptying and mop care still part of the decision.

The 90 min suggests a decent cleaning run before recharging. Think of a session fitted around an afternoon out, without treating the duration as a promise about how much of your house will be finished. Advertised endurance comes from the gentlest setting; stronger suction or mopping shortens it.

Want the whole home covered in a single session? DJI Romo A is better suited if you want to cover the whole home in one go, with higher battery life of 180 min. That longer advertised duration still cannot tell you the area cleaned per charge.

For this model, the practical choice is how much cleaning intensity you need. Increasing suction means allowing for an earlier recharge, so a longer available window gives you more breathing room than scheduling a run just before guests arrive.

With 400 mL available for collected crumbs and dust, the onboard bin sits in familiar territory for robot vacuum cleaners. It gives everyday dust and crumbs somewhere to go, with emptying frequency depending on what your household leaves behind. A home with shedding pets will give that container a different workload from a lightly used flat.

There is no station. Automatic emptying, mop washing and drying are therefore absent from this setup. Those jobs remain yours, so this is a better fit for someone seeking help with cleaning than someone seeking to remove upkeep from the week.

The dust still needs a forwarding address. Build a bin check into your routine, particularly when hair gathers around the sofa legs, and remember that the damp pad needs attention too.

Wooden flooring in the sitting room and tiles around the kitchen table create different cleaning needs. The dragged mop adds a damp wipe to suitable hard floors, useful in principle when vacuuming alone leaves you wanting a little more. It does not scrub like mopping by hand.

A sticky patch after supper may still send you to the cupboard for a mop. We would use this function to support regular floor care, rather than expect the pad to shift stubborn dried food.

For unfinished, waxed or poorly sealed wood, manufacturers advise checking that the flooring tolerates moisture before using a mop. Kitchen tiles and delicate wooden boards should not automatically get the same treatment simply because they share a doorway.

Navigation uses a gyroscope. That is worth knowing before buying, but it gives no basis for promising detailed room maps or precise room selection. If sending a robot to a particular room is central to your plans, confirm that function with the retailer before choosing.

App compatibility, Alexa compatibility and Google Assistant support are specified. These give you connected control options, which could be useful while your hands are busy preparing dinner. They do not, by themselves, establish which room controls the app offers.

Before a cleaning run, follow manufacturers' instructions by clearing charging cables, socks and small objects from the floor. Connected controls can make starting a chore more convenient; getting the room ready remains part of your contribution.
