Robot vacuums are worth it for most UK homes with hard floors, pets or no time for daily vacuuming, and a self-emptying model costs £57.46 to £189.78 a year over a five-year life with compatible parts. They do not fully replace a vacuum cleaner, because none of the robots here climbs stairs.
The best value is the Dreame L40 Ultra AE, which empties its bin, washes its mops in 75°C water and dries them for £316.35 on Amazon UK at the time of writing (October 2026). The ranked shortlist, with 5-year running costs in the makers' parts, is in Best robot vacuum UK 2026.
| Home | Worth it? | Pick | Price |
|---|---|---|---|
| Small flat, mostly hard floors | Yes | iRobot Roomba 105 Combo + AutoEmpty | £179.00 |
| Hard floors that need mopping | Yes | Dreame L40 Ultra AE | £316.35 |
| Mixed floors with rugs | Yes | eufy X10 Pro Omni | £349.00 |
| Pets that shed | Yes, most of all | Ecovacs DEEBOT X11 OmniCyclone | £699.00 |
| Thick rugs and high thresholds | Yes, with the right chassis | Roborock Saros 20 Neo | £749.00 |
| Stairs and several floors | One floor per robot | A second Roomba 105 Combo | £179.00 |
How much does a robot vacuum cost to run each year?
A self-emptying robot costs £21.24 to £45.98 a year in compatible parts from Amazon UK, and £89.97 to £179.98 a year where the maker publishes its own UK parts prices. Compare Electronic's year of parts assumes daily cleaning: two main brushes, matching side brushes, filters and mop pads, and enough dust bags for each dock's stated emptying interval.
| Robot | Dock bags a year | Maker parts a year | Compatible parts a year (Amazon UK) |
|---|---|---|---|
| iRobot Roomba 105 Combo + AutoEmpty | 5 (75-day dock) | £100.95: 2 x Replenishment Kit at £25.99, washable mop pads at £18.99, 2 x 3 bags at £14.99 (iRobot UK) | £21.66: one 30-piece kit (3 roller brushes, 8 bags, 8 filters, 3 mop pads) |
| Dreame L40 Ultra AE | 4 (100-day dock) | No UK maker parts price found | £45.98: two 26-piece kits at £22.99 (1 main brush and 6 bags each) |
| eufy X10 Pro Omni | 6 (bag every 2 months) | £89.97: 2 x Replacement Parts Kit at £34.99, 6 bags at £19.99 (eufy UK) | £21.24: one 30-piece kit (2 roller brushes, 7 bags, 7 filters, 6 mop pads) |
| Ecovacs DEEBOT X11 OmniCyclone | None (bagless station) | No UK maker parts price found | £28.63: one 20-piece kit (2 main brushes, 6 filters, 3 roller mop pads) |
| Roborock Saros 20 Neo | 6 (65-day dock) | £179.98: 2 x Accessory Pack at £89.99 (Roborock UK, listed for the Saros 20) | £39.98: two kits at £19.99 (1 main brush and 4 bags each) |
Maker parts cost four to five times as much as compatible kits: iRobot's own parts for the Roomba 105 Combo come to £100.95 a year against £21.66, and Roborock's to £179.98 against £39.98. The bagless Ecovacs DEEBOT X11 OmniCyclone saves on bags but still needs brushes, filters and mop rollers, and the Dreame L40 Ultra AE's 100-day dock needs only four bags a year. Compatible parts carry a trade-off: iRobot states that non-genuine parts may cut corners on materials and quality control.
What does a robot vacuum cost per year over five years?
Over a five-year life, the iRobot Roomba 105 Combo + AutoEmpty costs £57.46 a year with compatible parts, the lowest of the five, and the Roborock Saros 20 Neo £189.78, the highest. Compare Electronic's figure adds five years of parts to the Amazon UK price and divides by five; five years is a planning life, not a maker figure.
| Robot | Price | 5 years, compatible parts | Per year | 5 years, maker parts | Per year |
|---|---|---|---|---|---|
| iRobot Roomba 105 Combo + AutoEmpty | £179.00 | £287.30 | £57.46 | £683.75 | £136.75 |
| eufy X10 Pro Omni | £349.00 | £455.20 | £91.04 | £798.85 | £159.77 |
| Dreame L40 Ultra AE | £316.35 | £546.25 | £109.25 | n/a | n/a |
| Ecovacs DEEBOT X11 OmniCyclone | £699.00 | £842.15 | £168.43 | n/a | n/a |
| Roborock Saros 20 Neo | £749.00 | £948.90 | £189.78 | £1,648.90 | £329.78 |
The Dreame L40 Ultra AE costs £18.21 a year more than the eufy X10 Pro Omni on compatible parts, because its kits hold one main brush each, yet it is £32.65 cheaper to buy and rated at more than twice the suction. At £109.25 a year it works out at about £2.10 a week.

Who is a robot vacuum worth it for?
A robot vacuum is worth most to pet owners and homes with large areas of hard floor, and least to homes where stairs take most of the cleaning. Compare Electronic's table matches each situation to the maker figures that matter for it.
| Situation | What matters | Best fit | Maker figures |
|---|---|---|---|
| Pets | Anti-tangle brushes, no bags to fill | Ecovacs DEEBOT X11 OmniCyclone, £699.00 | 19,500 Pa, 38 CFM airflow, ZeroTangle 3.0 brushes, bagless station (Ecovacs) |
| Stairs | No robot here climbs stairs | Roomba 105 Combo as a second robot, £179.00 | ClearView LiDAR mapping; AutoEmpty dock holds up to 75 days of debris (iRobot) |
| Rugs and thresholds | Climbing height, mop lift | Roborock Saros 20 Neo, £749.00 | Climbs double-layer thresholds up to 8.8 cm; detaches mops on carpets up to 4.6 cm thick (Roborock) |
| Small flats | Price, no mopping of rugs | iRobot Roomba 105 Combo + AutoEmpty, £179.00 | Carpet detection stops it mopping rugs (iRobot) |
| Mostly hard floors | Mop washing and drying | Dreame L40 Ultra AE, £316.35 | 19,000 Pa; mops washed in 75°C water and dried with hot air (Dreame) |
| Large homes to mop | Battery life, water tank | eufy X10 Pro Omni, £349.00 | 8,000 Pa; 180 minutes of battery life; a 3 L clean water tank mops a 150 m² home 2 to 3 times (eufy, Amazon UK listing) |
Suction in pascals is each maker's own peak rating, measured its own way, so it compares models within a brand better than across brands; iRobot publishes no pascal figure for the Roomba 105 Combo. Stairs are the hard limit: a robot cleans the floor its dock is on, so a two-storey home pays for a second robot or carries one upstairs.
Cluttered floors are the other case where a robot earns less. A floor covered in cables, socks and toys needs tidying before each run, and the makers' obstacle figures vary widely: eufy says the X10 Pro Omni identifies over 100 objects, Dreame says the L40 Ultra AE avoids up to 120 types, and Roborock says the Saros 20 Neo recognises over 300. A household that cannot clear the floor most days should weigh that before paying £316.35 or more.
Which robot vacuum is worth buying?
The Dreame L40 Ultra AE is the robot vacuum most worth buying, at £316.35 on Amazon UK at the time of writing (October 2026). Dreame rates it at 19,000 Pa, and its dock empties the bin for up to 100 days, washes the mops in 75°C water and dries them with hot air.
Dreame L40 Ultra AE specifications (Dreame)
- Suction: 19,000 Pa
- Dock: auto-empties the bin for up to 100 days
- Mop care: washed in 75°C water, dried with hot air
- Brushes: TriCut anti-tangle brush and a liftable rubber brush
- Mopping: MopExtend reaches edges and furniture legs; mops lift 10.5 mm on carpet
- Obstacle avoidance: up to 120 object types
- In the box: 200 ml of cleaning solution
The L40 Ultra AE suits a home with large areas of hard floor and some rugs, and pet owners who want the TriCut brush to cut wrapped hair. Over five years it costs £109.25 a year with compatible parts. The compromises are a bagged dock, unlike the bagless Ecovacs DEEBOT X11 OmniCyclone, and no UK maker parts prices that Compare Electronic could find, so its running cost rests on compatible kits.

Frequently asked questions
Are robot vacuums worth the money in the UK?
Yes, for most homes with hard floors, pets or little time to vacuum. Over a five-year life with compatible parts, the iRobot Roomba 105 Combo + AutoEmpty costs £57.46 a year and the Dreame L40 Ultra AE £109.25 a year, at Amazon UK prices at the time of writing (October 2026). A robot does not replace a vacuum cleaner for stairs.
How much does a robot vacuum cost to run each year?
A self-emptying robot vacuum costs £21.24 to £45.98 a year in compatible parts from Amazon UK, or £89.97 to £179.98 a year in the makers' own parts where they publish UK prices. Maker parts cost four to five times as much: iRobot's parts for the Roomba 105 Combo come to £100.95 a year, against £21.66 for a compatible kit.
Is a robot vacuum worth it with pets?
Yes, more than in any other home, because shed hair builds up every day. The Ecovacs DEEBOT X11 OmniCyclone suits heavy shedding: Ecovacs rates it at 19,500 Pa with ZeroTangle 3.0 brushes, and its bagless station means more hair never means more dust bags. It costs £699.00 on Amazon UK at the time of writing (October 2026).
Can a robot vacuum clean stairs?
No. None of the five robots here climbs stairs, and each cleans the floor its dock sits on. A two-storey home either carries the robot upstairs or buys a second one, and the iRobot Roomba 105 Combo + AutoEmpty is the cheapest second robot at £179.00 on Amazon UK in October 2026. The stairs themselves still need a vacuum cleaner.
Do robot vacuums work on rugs and thick carpet?
Most do, and the better ones keep the mop off rugs. Roborock says the Saros 20 Neo climbs double-layer thresholds up to 8.8 cm and detaches its mops for carpets up to 4.6 cm thick. eufy lifts the X10 Pro Omni's mops by 12 mm on carpet, Dreame lifts the L40 Ultra AE's by 10.5 mm, and iRobot says the Roomba 105 Combo will not mop rugs.
Are cheap compatible robot vacuum parts worth using?
They cost far less but are not the maker's parts. A compatible Roomba 105 Combo kit costs £21.66 a year on Amazon UK against £100.95 for iRobot's own parts. iRobot states that non-genuine parts may cut corners on materials and quality control, and that a dirty filter weakens suction, so buyers who mix the two should keep filters and brushes fresh.
