Mapping and auto-empty are the features worth paying for
The £250–£500 band gets proper mapping and strong suction; auto-empty docks add real convenience. Mopping is a bonus, not a deep-clean replacement.
The jargon, decoded
| Spec | What it actually means | Does it matter? |
|---|---|---|
| LiDAR / mapping | Lets it navigate logically and save room maps/no-go zones. | Yes — get it |
| Auto-empty dock | Empties itself for weeks — big convenience. | Worth it for most |
| Suction (Pa) | Pickup power; higher helps on carpet. | Yes for carpet |
| Mopping | Wipes hard floors — light maintenance, not deep clean. | Bonus |
| App / no-go zones | Schedules and keeps it out of rooms. | Useful |
What actually matters
- 1Navigation is everything. LiDAR/camera mapping cleans in tidy rows and remembers your home; cheap "random bounce" bots miss patches and get stuck. This is the single biggest difference between a helper and a frustration.
- 2An auto-empty dock is the feature people love most. It empties the bin into a bag for weeks at a time — the difference between "set and forget" and emptying a tiny tray every day. It's where a lot of the step-up cost goes, and it's usually worth it.
- 3Mopping is a bonus, not a deep clean. Robot mops are great for daily light passes on hard floors; they won't replace a proper mop. Self-washing mop docks are convenient but pricey.
- 4Suction (Pa) matters most for carpet and pet hair. All-hard-floor homes don't need the highest numbers; carpets and pets do.
Typical UK price bands (2026)
| Budget | What you get |
|---|---|
| £130–£250 | Decent mapping, app control, no auto-empty. Great for smaller, mostly-hard-floor homes. |
| £350–£600 | Strong navigation, auto-empty dock, basic mopping — the sweet spot for most homes. |
| £700+ | Self-washing mop docks, top suction and obstacle avoidance — premium convenience. |
Buy this if · think twice if
Buy it if…
- ✓You have mostly hard floors or low-pile carpet
- ✓You want hands-off daily tidying
- ✓You'll use the app for schedules/no-go zones
Think twice if…
- ✗You have deep-pile carpet everywhere (uprights still win)
- ✗You expect mopping to replace a real mop
- ✗Your home is very cluttered with cables/small objects
Common mistakes to avoid
- ✕Buying on suction (Pa) alone — navigation and brush design matter more for real cleaning.
- ✕Paying for a self-washing mop dock if you've mostly carpet — you won't use it.
- ✕Forgetting running costs — replacement dust bags, brushes and filters add up; check they're cheap and available.

FAQ
Do robot vacuums replace a normal vacuum?
For day-to-day maintenance, mostly yes. For deep cleans, stairs and edges you'll still want a cordless or upright occasionally.
Is the auto-empty dock worth it?
For most people, yes — it's the feature that turns the robot from a chore into genuinely hands-off. Budget for replacement bags.
Are they good with pet hair?
Mid-range and up handle pet hair well; look for higher suction and anti-tangle brushes, and read pet-specific reviewer notes.
