Quick answer

A cordless stick vacuum suits most flats and smaller homes: grab it, clean, put it back on the charger. A robot vacuum is best for keeping floors tidy day to day, especially with pets or hard floors, but it rarely replaces a main vacuum for stairs, corners and deep carpet cleaning. A corded upright is still the choice for larger homes with lots of carpet, because it never runs out of battery and usually has a bigger bin. Many households end up with a stick or upright as the main cleaner and a robot for maintenance.

How each type works

  • Cordless stick: a lightweight vacuum powered by a rechargeable lithium-ion battery, usually with a detachable handheld section for sofas, stairs and the car.
  • Robot vacuum: a low, round or D-shaped unit that cleans on a schedule and returns to a charging dock. Navigation ranges from simple bump sensors to lidar or camera-based mapping. Some include mopping, and some docks empty the bin automatically.
  • Corded upright: a traditional mains vacuum you push along. It runs as long as you need, and often has a wide brush bar suited to carpets.

If you are only choosing between two of these, our existing guides go deeper: cordless stick vs corded upright and how to choose a robot vacuum.

Side-by-side comparison

Cordless stick Robot vacuum Corded upright
Run time Limited by battery; manufacturers quote run times that usually drop on the highest power setting Limited by battery, but returns to the dock to recharge and can resume on many models Unlimited while plugged in
Effort Low; light to carry Very low once set up Higher; heavier to push and carry upstairs
Stairs Good, especially in handheld mode Can’t climb stairs Possible, but awkward on many models
Deep carpet cleaning Varies by model and power mode Usually lighter cleaning Usually strong
Bin size Small Very small (larger if the dock self-empties) Usually largest
Storage Wall dock or stand Dock needs a spot near a socket Needs a cupboard or corner
Upkeep Battery wears over years; check if replaceable Brushes, filters, sensors and dock bags Belts, filters and bags (if bagged)

These are general traits of each type, not results from our own testing. Check the manufacturer’s specification for the model you are considering.

Which suits which home?

Home or situation Usually a good fit Why
Flat or small house, mostly hard floors Cordless stick, optionally plus a robot Quick cleans; robot keeps crumbs and dust down
Large house with lots of carpet Corded upright, or a stick with a spare battery No run-time worries for long sessions
Pets that shed Robot for daily pickup plus a stick or upright Little-and-often helps with hair; look for tangle-resistant brushes
Allergies Any type with a sealed system and HEPA filter Electrical Safety First lists HEPA filters as useful for allergens and fine dust
Limited mobility or a bad back Robot plus a light stick Less lifting and pushing
Lots of stairs Cordless stick Handheld mode makes stairs easier

Running costs: how to work them out

The formula is the same for any appliance:

Cost = power in kW × hours used × unit rate

Under the Ofgem price cap for 1 October to 31 December 2026, the average electricity unit rate on Direct Debit is 26.32p per kWh. Battery vacuums are easier to estimate from the battery’s capacity in watt-hours (Wh), which is often printed on the battery or in the manual. If it shows volts and mAh instead, Wh = volts × mAh ÷ 1,000. Charging uses a little more energy than the battery holds, so we add a rough allowance for losses.

The figures below use example ratings, not any specific model:

Example Energy per use Cost per use at 26.32p
Corded upright rated 0.75kW, used for 30 minutes 0.75 × 0.5 = 0.375kWh about 9.9p
Cordless stick, 25.2V 2,500mAh battery (about 63Wh), full charge with about 20% losses about 0.076kWh about 2p
Robot vacuum, 14.4V 5,200mAh battery (about 75Wh), full charge with about 20% losses about 0.09kWh about 2.4p

In every case the electricity cost is small. The bigger long-term costs are usually replacement filters, brushes, dock bags and, for battery models, an eventual replacement battery. Robot docks also draw a little power while waiting, so check the standby figure if it is listed. Your own unit rate depends on region and tariff, and Ofgem will announce the January to March 2027 cap on 25 November 2026.

Safety points worth knowing

Electrical Safety First’s advice for vacuum cleaners and robot vacuums includes:

  • Buy from a reputable retailer rather than an unknown third-party seller, and make sure the charger or dock has a UK 3-pin plug. Don’t use a travel adaptor for a robot vacuum’s charger.
  • Only use the original charger or one the manufacturer confirms is suitable, and only use batteries approved by the manufacturer. Second-hand batteries and chargers can be a serious fire risk.
  • Check plugs and cables for damage or scorch marks, and don’t use a vacuum with visible damage.
  • Register the vacuum with the manufacturer so you can be told about any safety recall.
  • Recycle old lithium-ion batteries properly; don’t put them in household bins.

Which should you buy?

  • One vacuum for a flat or small home: a cordless stick with a removable battery if you can find one in your budget.
  • Bigger home, lots of carpet, or you hate charging things: a corded upright.
  • You want floors to stay tidy without thinking about it: a robot vacuum, plus a stick or upright for stairs and deeper cleans. Read robot vacuum and mop combos: are they worth it? if you have lots of hard floor.
  • Pets or allergies: look for HEPA filtration, a sealed system and tangle-resistant brush rolls whichever type you choose.

Black Friday checklist for vacuums

  1. Check the battery spec, not just the headline run time. Quoted run times are usually on the lowest power mode. Look for the run time on the mode you’ll actually use.
  2. Ask whether the battery is replaceable and whether spare batteries and filters are sold in the UK.
  3. For robots, check navigation and app features. Lidar or camera mapping, no-go zones and obstacle avoidance make a big difference in a cluttered home. Our Black Friday robot vacuum guide has a fuller checklist.
  4. Compare model numbers carefully. Some ranges come in near-identical variants with different accessories.
  5. Watch “was” prices. See how “was” prices work, and check our Black Friday deals page. Small extras such as spare filters often turn up in deals under £10.

Frequently asked questions

Can a robot vacuum replace my normal vacuum?

For some small homes with mostly hard floors, it can cover daily cleaning. Most people still need a stick or upright for stairs, sofas, corners and deeper carpet cleans, because robots have small bins and can’t climb stairs.

Are cordless vacuums as powerful as corded ones?

It depends on the model and power mode. Many cordless sticks have a boost mode, but it drains the battery quickly. A corded upright delivers its power for as long as it is plugged in, which helps on large carpeted areas.

How long do cordless vacuum batteries last?

Lithium-ion batteries gradually lose capacity with use and age. Manufacturers give their own guidance and warranty terms, so check these and whether a replacement battery is available before you buy.

Is it safe to leave a robot vacuum charging all the time?

Robot vacuums are designed to sit on their docks. Electrical Safety First advises using only the supplied charger, keeping an eye on charging, and making sure the dock has a UK plug. Follow the manufacturer’s instructions for your model.

How much electricity does a vacuum use?

Not much. Using example ratings at the 26.32p per kWh cap rate, a 30-minute clean with a 0.75kW corded upright is about 9.9p, and a full charge of a typical cordless or robot battery is about 2p to 2.5p.
