Best robot vacuums under £500

In its favour

• At about 8 cm (3.2 in) tall it can reach under low sofas, beds and cabinets.
• TruEdge 2.0 pushes the side brush and mop out towards walls and into corners.
• The Omni station self-empties, washes the mop, dries it with hot air and fills water.

Good to know

• The listing does not say whether the mop uses rotating pads or another design.
• Dust bag size and how many days it lasts are not stated.

In its favour

• Compact base tucks under cabinets, and still empties into a 3.2 L bag for up to 90 days.
• Washes mops with 45°C water and dries them with cool air, according to Lefant.
• Dual-band 2.4GHz and 5GHz Wi-Fi, useful in flats with crowded networks.

Good to know

• The listing does not give the base station's height or width in cm, so measure your cabinet gap carefully.
• A washing dock needs water tanks refilled and emptied by hand.

In its favour

• Roller brush reverses and the Pro-Detangle Comb flips down to remove wrapped hair automatically.
• Station dust bag holds 2.5 L and only needs replacing every 2 months, per eufy.
• Recognises over 100 objects such as wires, shoes and toys, even at night.

Good to know

• 8,000 Pa is the lowest stated suction in this guide, so thick carpets may need extra passes.
• Only 2.4 GHz Wi-Fi is supported, and pet waste is not listed among the recognised objects.

In its favour

• Bagless base holds up to 60 days of debris and uses True HEPA filtration.
• Matrix Clean makes a grid of passes over dirty areas for more thorough carpet cleaning.
• Sonic mopping scrubs hard floors 100 times per minute, with a Matrix Mop option for stains.

Good to know

• The base does not wash or dry the mop pads, so they need rinsing by hand.
• No Pa figure is listed and runtime is a shorter 110 minutes.

In its favour

• PrecisionVision AI recognises pet waste, cords and socks and navigates around them.
• Dual rubber brushes plus dual edge-sweeping brushes for hair along skirting boards.
• AutoWash Dock gives up to 75 days of auto-emptying and heated roller washing and drying.

Good to know

• Runtime and battery capacity are not stated in the listing.
• The 13,000 Pa figure comes from the spec table only, as the bullets compare suction with older Roombas.

In its favour

• Rated for 300 minutes per charge, the longest runtime in this guide.
• The bagless station removes the need for dust bags and holds up to 45 days.
• Carpet detection raises suction and avoids mopping on rugs automatically.

Good to know

• The listing gives conflicting mop descriptions, so the mop design is unclear.
• No camera or structured light avoidance is mentioned, only laser mapping.

In its favour

• Empties into a 5 L bag claimed to last up to 150 days, the longest interval here.
• 13,000 Pa suction with the anti-tangle DuoBrush for long hair and pet fur.
• 32 water levels and editable multi-floor maps in the app.

Good to know

• The base does not wash or dry the mop, so it is behind the full stations on mopping.
• No obstacle avoidance camera or sensor is described beyond anti-collision.
