Do you need a robot vacuum with mapping?
Mapping isn't essential, but it's worth paying for if you have a larger home, several rooms or areas you don't want your robot to enter. Rather than wandering around until it encounters an obstacle, mapping allows a robot vacuum to learn your home's layout, clean rooms more systematically and return to its dock efficiently.
More advanced models also let you create no-go zones, clean individual rooms and set different cleaning routines through an app. If you're buying a robot vacuum for one or two straightforward rooms, a cheaper model without mapping, such as the Lefant M210P, may be perfectly adequate.
How much should I spend on a robot vacuum?
You can buy a decent robot vacuum for around £100, but expect to pay more for features such as intelligent mapping, mopping, obstacle avoidance and self-emptying. How much is worth spending depends largely on how much of the cleaning you want the robot to handle for you.
Budget robot vacuums (around £100–£250) are best for straightforward everyday cleaning. You'll usually sacrifice sophisticated mapping, obstacle avoidance and automated maintenance, but models such as the Lefant M210P can still keep on top of crumbs, dust and hair.
Mid-range robot vacuums (around £250–£600) tend to add better navigation and mapping, stronger suction and more capable mopping. This is where we'd look if you want a robot to clean several rooms regularly rather than simply maintain one area.
Premium robot vacuums (£600+) increasingly automate the jobs around the cleaning, too. Features can include advanced obstacle recognition, self-emptying dust bins and docks that wash and dry mop pads. Models such as the eufy X10 Pro Omni and Dyson Spot+Scrub AI cost considerably more, but you're largely paying for better cleaning plus less day-to-day intervention.
