Robot vacuum or cordless stick vacuum: which is right for you
A robot keeps the floor clean every day without you thinking about it; a cordless stick cleans more deeply and reaches where a robot cannot. If you can only have one, it depends on how much clear floor you have and who sheds in your home.
Quick verdict
- Buy a robot vacuum if… you have plenty of clear hard floor, pets that shed every day or little time, and a 'maintenance clean' is enough. With a self-emptying dock you can forget about it for weeks.
- Buy a cordless stick vacuum if… your home has thick carpets, stairs, lots of low furniture or steps, or you also want to do the sofa, the car and the corners. It cleans more deeply in fewer passes.
- Have both if… you have children or pets and want the floor clean every day without effort: the robot does the daily run and the stick does the weekly once-over and everything the robot misses.

Which one really cleans better
A cordless stick has more suction and a larger motorised brush: in one pass it lifts more dust and grit, especially from carpets and floorboard gaps. A robot has less power, but it runs every day, so dust never gets the chance to build up.
In practice, a hard floor a robot vacuums daily is often cleaner by midweek than one given a thorough going-over on Saturday. What robots do badly: corners, skirting boards, under very low furniture and deep-pile rugs.
Do not compare robots and sticks by the pascals (Pa) or air watts (AW) on the box: they are not measured the same way. Look for real tests with grit and hair.
Which home suits each one
- A flat with hard floors, little furniture and few cables on the floor: ideal robot territory.
- A house with stairs: a robot cleans one floor (or you carry it up); a stick does them all.
- Lots of thick or deep-pile carpet, common in UK homes: a stick. Robots get stuck or leave it half done.
- Pets: a daily robot run picks up hair before it forms clumps; look for a rubber brush roll, which does not tangle.
- Toddlers and toys on the floor: a robot needs a tidy floor. If that is not going to happen, go for a stick.
Is a mopping robot worth it?
Cheap mopping robots drag a damp pad: they lift fine dust and footprints, not a dried-on spill. Mid-range and premium ones have spinning mops that press down, lift when they reach a rug, and get washed and dried in the dock.
If your home is mostly tiles, laminate or wooden floors that you mop often, a robot with spinning mops and a washing dock really does save work. If you only want to vacuum, do not pay for mopping.
The work they leave you
A robot without a dock needs emptying every day or two and its brush cleared of hair every week. With a self-emptying dock, the dock's bag lasts four to eight weeks, and replacement bags cost around £2–£4 each.
A cordless stick is emptied after each use and its filter washed every month. The battery is the part that wears out first: after three or four years it runs noticeably shorter. A removable battery sold on its own extends its life a lot.
What to look for when buying
- Robot: laser navigation (LiDAR) so it cleans room by room and does not bump around; camera or gyroscope models are cheaper and clumsier.
- Robot: height (under 10 cm if you have low sofas and beds) and a rubber brush roll if there is long hair.
- Robot: an app with no-go zones and schedules; a self-emptying dock if you do not want to empty it yourself.
- Stick: removable battery, anti-tangle motorised brush and a tool for the sofa and crevices.
- Stick: under 3 kg if you will use it daily or on stairs and ceilings.
- Both: easy-to-find spares (brushes, filters, bags) and UK customer support.

Frequently asked questions
Can a robot vacuum replace a normal vacuum?
In a flat with clear hard floors, almost entirely. In homes with thick carpet, stairs or lots of low furniture, no: you will still want a stick for the weekly once-over and the places the robot cannot reach.
Is a self-emptying dock worth it?
Yes, if you have pets or a large home: the robot empties itself and the bag lasts four to eight weeks. In a small flat without pets, emptying it by hand every couple of days is not much work.
How long does a cordless vacuum battery last?
Between 25 and 70 minutes depending on the model and power setting; much less on maximum. It loses capacity over the years, so it is worth choosing one with a removable battery you can buy separately.
Which robot vacuum is best for dog or cat hair?
One with a rubber brush roll (not bristles), strong suction and a self-emptying dock, because the bin fills faster. Scheduling it daily stops hair from building up.
Do mopping robots mop well?
Fixed-pad models remove dust and footprints, not dried-on marks. Models with pressurised spinning mops and a dock that washes them do a much better job and come close to hand-mopping for everyday cleaning.
