The iRobot Roomba i4 at £134.95 offers the best balance of cleaning performance and affordability for most homes, though budget hunters should consider the Lenovo T1s at £142, and those willing to spend more will see genuine improvements in navigation and dustbin capacity at the £300–£400 tier. Anything above £1,500 delivers premium features like advanced LiDAR, self-emptying stations, and hybrid mopping — but your floor type and home size should determine whether that investment makes sense.
Our Top Picks
iRobot Roomba i4 — Best value for everyday cleaning
£134.95 | Delivers reliable cleaning without the premium price tag.
The Roomba i4 strikes the sweet spot between cost and capability. It features Dirt Detect technology to concentrate cleaning effort on high-traffic areas, a 0.4L dustbin, and connectivity via the iRobot app for scheduling. Runtime is around 90 minutes, sufficient for most small to medium homes. You won’t get mopping, advanced obstacle avoidance, or self-emptying features at this price, but for essential daily cleaning, it’s unbeatable value.
Shark Ai Ultra 2-in-1 Robot Vacuum and Mop — Best budget hybrid system
£349.95 | Vacuum and mop in one without skimping on either function.
This model combines vacuuming and wet mopping with a 0.6L dustbin and 2-in-1 capability. The XL HEPA self-empty base means you’ll empty it roughly every 30 days rather than weekly, saving time. AI-powered room mapping avoids obstacles intelligently, and it works with Alexa voice control. Ideal if you need hybrid cleaning on a realistic budget — genuine value at under £350.
Eureka E10s Robot Vacuum and Mop — Best self-emptying entry point
£299 | Affordable self-emptying with mopping capability.
The E10s delivers both vacuuming and mopping with a self-emptying station, reducing hands-on maintenance to roughly monthly intervals. Its 2.2L dustbin capacity is generous for the price, and it offers room mapping and scheduled cleaning via app control. Slightly cheaper than comparable Shark models, making it excellent value for homes wanting automation without premium pricing.
Dreame X60 Ultra — Best premium performance
£1,499.99 | Delivers flagship-level navigation, suction, and convenience features.
This is where you get advanced LiDAR technology, 4000Pa of suction power, hot-water mopping (not just dampening), and a massive 4L self-empty dustbin. Runtime extends to 120 minutes, covering larger homes on a single charge. The premium price reflects real improvements in obstacle avoidance, multi-floor mapping, and reduced maintenance intervals. Only justified if you have a large home (2,000+ sq ft), multiple floor types, or pet hair challenges.
Dyson 360 Vis Nav Robot Vacuum Cleaner — Best for tech enthusiasts
£280 | Premium brand engineering in a mid-range price point.
Dyson’s offering combines their reputation for suction power with 360-degree camera navigation and whole-home mapping. Dust is ejected into a base station automatically (reducing full emptying frequency), and it integrates with smartphone control. Particularly suited to buyers who value Dyson’s engineering heritage, though suction power alone doesn’t always translate to faster cleaning times compared to slightly cheaper rivals.
Lenovo T1s — Best alternative budget pick
£142 | Competitive performance to the Roomba i4 at a similar price.
Offers basic LiDAR navigation, a 0.5L dustbin, and 90-minute runtime. Works with Alexa and Google Home for voice control. Slightly less brand recognition than iRobot, but nearly identical cleaning capability for homes under 100 square metres. Choose this if you find better availability or prefer a lesser-known brand.

How We Chose
- Value threshold: Prioritised models delivering ≥90-minute runtime and app control under £300, since most buyers don’t need premium features for basic cleaning.
- Self-emptying tiers: Featured at least one model at each price point (£299, £349, and £1,499) so you can see the genuine feature jumps that justify spending more.
- Real-world maintenance: Ranked by actual hands-on effort — dustbin size, emptying frequency, and mopping capability matter more than marketing claims about “AI” or “smart” features.
- Home size suitability: Matched each pick to a typical use case (small flat, medium semi-detached, large detached house) so you can skip models irrelevant to your needs.
The Bottom Line
Buy the iRobot Roomba i4 at £134.95 if you have a small to medium home and want reliable daily cleaning without fuss. If you need mopping or self-emptying capability, step up to the Shark Ai Ultra 2-in-1 or Eureka E10s at the £299–£350 mark — both offer genuine convenience improvements. Only consider the Dreame X60 Ultra at £1,499.99 if you have a large home (2,000+ sq ft) with multiple floor types or significant pet hair, since premium features justify the outlay only at that scale.
Frequently Asked Questions
What are the best robot vacuums under £150?
The iRobot Roomba i4 (£134.95) and Lenovo T1s (£142) are the top two choices. Both offer 90-minute runtimes, app control, and reliable suction for homes under 100 square metres. The Roomba has slightly better brand longevity (easier spare parts), whilst the Lenovo offers identical core performance at a similar price. For budget buyers, either is safe — the Roomba wins on resale value.
Do I actually need a self-emptying robot vacuum?
It depends on your tolerance for maintenance and home size. A self-emptying base becomes worthwhile if your home exceeds 1,500 sq ft or you have pets (larger dustbin requirements). Weekly manual emptying is fine for small flats; self-emptying reduces the task to roughly monthly intervals, which justifies the £100–£150 price premium for most users. If you forget maintenance tasks easily, a self-emptying model is worth the investment.
Are expensive robot vacuums worth buying, or is mid-range sufficient?
Mid-range models (£300–£400) deliver 90% of the value you need — mapping, self-emptying, and mopping. Premium models above £1,000 add features like hot-water mopping, superior obstacle avoidance, and multi-floor memory mapping. Spend premium only if you have a large home (2,000+ sq ft), multiple floor types, or significant pet hair challenges. For typical flats and small houses, a £300 model will serve you well for 3–4 years.
Which robot vacuum works best with pets?
Look for models with ≥3000Pa suction and large dustbin capacity (0.5L or larger). The Shark Ai Ultra 2-in-1 and Eureka E10s both handle pet hair well at mid-range prices. If budget allows, the Dreame X60 Ultra at £1,499.99 offers 4000Pa suction and a 4L self-empty dustbin specifically engineered for pet hair. Pet owners should prioritise suction power and dustbin size over navigation features — hair removal is more important than obstacle avoidance in pet households.
