Robot Vacuums price comparison UK
Robot vacuums have quietly become one of the most competitive categories in home tech — and the price spread tells the whole story. With models ranging from 175 £ to 1,199 £, the gap between a basic bump-and-go unit and a fully autonomous cleaning system with LiDAR navigation, self-emptying station, and AI obstacle avoidance is enormous. Knowing where to draw the line for your home is what separates a smart purchase from an expensive disappointment.
Dreame leads the pack in sheer volume here, with 36 models averaging around the premium end of the market. Roborock, despite fewer listings, commands the highest average price — a reflection of its reputation for best-in-class SLAM navigation and robust mopping systems. At the other end, Xiaomi and Hoover offer genuine value for money, particularly for hard-floor households that don't need the full suite of autonomous features. The median price sits at 381 £, which is roughly where the market's sweet spot lies: you get LiDAR mapping, decent suction (typically 3000+ Pa), and app-based scheduling without paying over the odds.
One thing worth flagging: suction power figures quoted by manufacturers are often measured under ideal conditions. A robot claiming 4000 Pa on hard floors may struggle considerably on thick-pile carpet — always cross-reference with independent tests from sources like Which? or TechRadar before committing. Similarly, "mopping" on cheaper models often means little more than a damp cloth dragged across the floor at fixed pressure. If mopping is a priority, look for vibrating mop heads and dual-tank systems, features that only start appearing reliably above 299 £.
Self-emptying stations have shifted from luxury to near-standard at the top of the market, and for good reason — they reduce your interaction with the dustbin from weekly to roughly monthly. If you have allergies or pets, this feature alone can justify the premium. For a broader look at floor care, our Vacuums and Stick Vacuums & Electric Brooms categories cover complementary options, whilst Vacuum Accessories & Supplies is worth bookmarking for replacement brushes and filters down the line.
Our comparison across 212 products tracks live prices from retailers including Amazon, Currys, and John Lewis — so if you spot a model you like, it's worth setting a price alert before Black Friday or the January sales, when this category typically sees its sharpest discounts.
How to Choose a Robot Vacuum: What Actually Matters
Most buyers fixate on suction power, but navigation technology is the single biggest factor separating a robot that cleans your whole home efficiently from one that misses corners and gets stuck under the sofa. Here's what our analysis of the market actually points to.
Navigation: LiDAR vs Camera vs Random
LiDAR-based navigation (used by Roborock, Dreame, and higher-end Xiaomi models) uses laser pulses to build a precise room map before cleaning. The result is systematic, row-by-row coverage with far fewer missed patches. Camera-based SLAM (common in mid-range iRobot models) is effective but can struggle in low light. Random-pattern navigation — still found on models below 299 £ — is genuinely inefficient: it covers most of the floor eventually, but wastes battery and time doing so. For homes larger than two rooms, LiDAR is worth the premium.
Suction Power for Your Floor Type
Entry-level robots (1500–2000 Pa) handle hard floors and light dust perfectly well. The jump to 3000+ Pa makes a real difference on low-pile carpets and for pet hair. Above 4000 Pa, you're in premium territory — useful for thick carpets, but overkill for a flat with laminate floors. Be sceptical of headline figures: manufacturers measure peak suction, not sustained performance. If your home is mostly hard floors, don't pay extra for suction you won't use.
Mopping Capability: Genuine or Gimmick?
Basic mopping — a fixed damp pad — is largely cosmetic. It removes light surface dust on hard floors but won't tackle dried-on marks or grout lines. Genuine mopping starts with vibrating mop heads (measured in oscillations per second) and adjustable water pressure. Dual-tank systems that keep clean and dirty water separate are the gold standard. These features appear consistently above 381 £. If mopping is a core requirement rather than a nice-to-have, budget accordingly — or consider pairing a mid-range robot vac with a dedicated steam cleaner.
Self-Emptying Station: Worth It for Allergy Sufferers
A self-emptying station automatically transfers dust from the robot's small onboard bin into a larger bag or container at the dock — reducing your hands-on emptying from every few days to roughly once a month. For pet owners or allergy sufferers, this is transformative. The trade-off is cost: self-emptying models typically start above 381 £, and replacement bags for the station are an ongoing expense. Check bag availability and pricing before buying — some brands make this proprietary and expensive.
Obstacle Avoidance: Protecting Your Cables and Furniture
Basic robots use bumper sensors — they detect obstacles by hitting them, which means repeated low-speed collisions with chair legs and skirting boards. Mid-range models add infrared sensors for better proximity detection. Premium systems use camera or LiDAR-based AI to identify specific objects — cables, socks, pet waste — and route around them. If your home has cables on the floor or a dog, investing in proper obstacle avoidance saves considerable frustration. Models with AI avoidance tend to sit above 719 £.
Battery Life vs Home Size
Most robots quote runtime in minutes (typically 90–180 minutes) rather than square footage, which makes comparison tricky. A 120-minute runtime covers roughly 100–150 m² on a single charge under normal conditions — adequate for most UK flats and smaller houses. Larger homes need either a longer-running model (5000+ mAh battery) or one that supports auto-resume: returning to charge mid-clean and picking up where it left off. Auto-resume is standard on most models above 299 £, but worth confirming before purchase.
- Entry-level (From 175 £ to 299 £) : Expect random-pattern or basic gyroscope navigation, manual emptying, and limited app functionality. Brands like Hoover and MEDION sit here. Fine for small, clutter-free flats with hard floors — but don't expect systematic room coverage or reliable carpet cleaning.
- The sweet spot (From 299 £ to 381 £) : This is where LiDAR navigation becomes accessible. Models from Xiaomi, Eufy, and entry-level Dreame offer proper room mapping, app scheduling, and decent suction. The Eufy L60 and Xiaomi S20 are representative — solid performers without the premium price tag.
- For the genuinely demanding (From 381 £ to 719 £) : Self-emptying stations, advanced mopping with vibrating heads, and AI obstacle avoidance start appearing here. Dreame and iRobot dominate this segment. A good choice for larger homes, pet owners, or anyone who wants to genuinely set-and-forget their floor cleaning.
- Premium and flagship (Over 719 £) : Roborock and top-tier Dreame models occupy this space. Expect the full package: LiDAR + AI avoidance, self-emptying with mop-washing capability, multi-floor mapping, and integration with Google Home, Alexa, and Apple HomeKit. Justifiable for large homes with mixed flooring — harder to justify for a two-bedroom flat.
Top products
- Eufy L60 Hybrid Robot Vacuum with Self Empty Station (Eufy) : The best value self-emptying robot in the comparison — LiDAR navigation, hybrid mopping, and an auto-empty station at a price that undercuts most rivals. The mopping is basic rather than vibrating, so don't buy it primarily for hard floors.
- Dreame L40 Ultra 3.5 L Combi White (Dreame) : Dreame's flagship combi unit with a generous 3.5 L station capacity and advanced mop-washing functionality. Excellent for large homes with mixed flooring. Overkill — and overpriced — for a small flat.
- Xiaomi S20 0.4 L Bagless White (Xiaomi) : The most accessible LiDAR-equipped model in the top 15. Solid navigation and app integration at a price well below the median. No self-emptying station and mopping is rudimentary — but for a no-fuss daily cleaner on hard floors, it's hard to beat at this price.
- Dreame L10s Ultra Gen 2 Bagless White (Dreame) : A strong mid-to-premium performer with upgraded obstacle avoidance over its predecessor. Better real-world mopping than most in this price bracket. The Gen 2 refinements are genuine improvements, not just a rebrand.
- TP-Link Tapo LiDAR Navigation Robot Vacuum (TP-Link) : The outsider pick. TP-Link's Tapo ecosystem integration is genuinely well-executed, and LiDAR navigation at this price is competitive. Less proven than Dreame or Roborock for long-term reliability, but worth considering if you're already in the Tapo smart home ecosystem.

Frequently Asked Questions
What is the difference between LiDAR and camera-based navigation in robot vacuums?
LiDAR uses laser pulses to build a precise map of your home before cleaning, resulting in systematic, efficient coverage regardless of lighting conditions. Camera-based navigation relies on visual data and can struggle in dim rooms or at night. For most UK homes, LiDAR is the more reliable choice — it's faster, misses fewer areas, and handles furniture rearrangements better. Camera systems can be equally capable in well-lit environments, but LiDAR is the safer bet if you plan to run the robot overnight.
Is mopping on a robot vacuum actually effective, or is it just a marketing feature?
On most budget models, mopping is little more than a damp cloth dragged at fixed pressure — it removes surface dust but won't tackle dried spills or grout. Effective mopping requires a vibrating mop head and adjustable water pressure, features that only appear reliably on models priced above 381 £. If clean hard floors are a priority, look specifically for dual-tank systems and vibration frequency specs rather than just the presence of a water tank.
How often does a robot vacuum actually need emptying?
Without a self-emptying station, most robots need their dustbin emptied every 1–3 cleaning sessions, depending on home size and how much debris is present. With a self-emptying station, that drops to roughly once a month. For allergy sufferers, the self-emptying feature is particularly valuable as it minimises contact with collected dust and allergens. Bear in mind that replacement bags for self-emptying stations are an ongoing cost — check availability before buying.
Can a robot vacuum replace a traditional hoover entirely?
For most households, no — at least not completely. Robot vacuums excel at maintaining day-to-day cleanliness on hard floors and low-pile carpets, but they struggle with deep carpet cleaning, stairs, and corners. The realistic use case is using a robot for daily or every-other-day maintenance, with a traditional upright or cylinder vacuum for a thorough weekly clean. Homes with thick carpets or lots of pet hair will notice the limitation most acutely.
What should I watch out for when buying a cheap robot vacuum?
The biggest pitfall with budget models is random-pattern navigation — it sounds minor but means the robot can spend 90 minutes cleaning the same areas repeatedly whilst missing others entirely. Also watch for inflated suction figures, minimal obstacle avoidance (bumper-only sensors cause repeated collisions), and proprietary apps that are poorly maintained or discontinued. Brands with limited UK presence can also make spare parts — replacement brushes, filters, side brushes — difficult to source. Check accessory availability before committing.
Do robot vacuums work well on carpets?
It depends heavily on carpet pile height. Most robot vacuums handle low-pile and medium-pile carpets well, provided suction is 3000 Pa or above. Thick-pile or shag carpets are genuinely problematic — the robot can struggle to transition onto them, and brush rolls can get tangled. Models with automatic carpet detection and boost mode (which increases suction when carpet is detected) perform significantly better. If your home is predominantly carpeted, prioritise suction power and carpet detection over mopping features.
Which robot vacuum brands offer the best after-sales support in the UK in 2026?
iRobot and Shark have the strongest UK after-sales infrastructure, with accessible customer support and widely available spare parts through major retailers like Currys and Amazon. Roborock and Dreame have improved significantly, with UK-specific support lines and parts available online. Xiaomi's support can be inconsistent depending on where the product was purchased — buying from an authorised UK retailer rather than a grey-market import is important. Smaller or less-established brands are the highest risk: if the UK distributor changes, warranty claims can become very difficult to pursue.
