Best robot vacuums under £300

In its favour

• 20,000 Pa Vormax suction is the highest figure among these seven robots.
• The base empties into a 4 L bag, claimed to hold up to 120 days of debris.
• Dual anti-tangle design on the main and side brushes is aimed at long hair and fur.

Good to know

• The mop is a pad fed by the tank, not rotating pads, and the base does not wash it.
• Obstacle avoidance details are not stated beyond lidar navigation.

In its favour

• Lidar laser mapping lets you clean by room and set boundaries in the app, according to the listing.
• Runs for up to 2.5 hours on its 3,200 mAh battery, enough for most flats in one pass.
• The compact charging station takes up far less floor space than a self-emptying base.

Good to know

• No suction figure appears anywhere on the listing, so you cannot compare it on power.
• There is no self-emptying base and the dust box holds only 325 ml, so you empty it by hand.

In its favour

• Dual pads rotate at 180 RPM with pressure to lift coffee stains and kitchen spills.
• Station auto-cleans the pads, air-dries them and empties dust in about 10 seconds.
• 4 L clean water tank and up to 75 days hands-free, with a UK model number on the listing.

Good to know

• Mop lift height and water-flow settings are not stated in the listing.
• 6,000 Pa is the lowest suction in this guide, so it is better suited to hard floors than carpets.

In its favour

• Auto-empty base with a 4 L bag that the maker says holds up to 90 days of debris.
• Stores up to 5 maps and climbs thresholds up to 2 cm, useful in multi-floor homes.
• Control by app, voice, remote or buttons, and the listing gives a 2-year warranty.

Good to know

• The mop is a static cloth, and the base does not wash it.
• Less established brand than Dreame, Roborock or Shark, so check UK support before buying.

In its favour

• The bagless base holds up to 60 days of debris and needs no disposal bags.
• Self-cleaning brushroll is designed against hair wrap on carpets and hard floors.
• Detects and avoids objects in its path, and resumes cleaning after recharging.

Good to know

• Runtime is listed at 60 minutes, the shortest here, so larger homes may need a recharge mid-clean.
• There is no mopping function and no Pa figure, only a comparison against a rival.

In its favour

• The 5,200 mAh battery is rated for up to 150 minutes and the robot resumes where it left off after charging.
• Carpet boost raises suction automatically when it moves from hard floor onto carpet.
• Listing dimensions give a height of 9.6 cm, low enough for many sofas and beds.

Good to know

• At 4,000 Pa it has the lowest stated suction here, so expect less pull on thick rugs.
• No self-emptying base, and the app only works on 2.4 GHz Wi-Fi.

In its favour

• Rated for up to 200 minutes on a charge, the longest stated runtime in this guide.
• Saves 5 maps and up to 10 no-go zones, with auto carpet boost.
• The listing gives a 2-year UK warranty once you register.

Good to know

• No self-emptying base, and the dust bin is 340 ml.
• Model naming on the listing is vague, so the exact model is hard to match against other sellers.
