Best self-emptying robot vacuums

In its favour

• Compact 32.6 cm base is 59% smaller than the previous generation, according to Xiaomi.
• 4 L bag lasts up to 90 days, so emptying is rare.
• 10,000 Pa suction and a five-step anti-tangle system aimed at long-haired pets.

Good to know

• Runtime of 100 minutes is the shortest listed here, though enough for many flats.
• Mopping is a basic pad and tank; the base does not wash or dry it.

In its favour

• Bagless base needs no disposal bags, and Shark says it holds up to 45 days of dirt and debris.
• Self-cleaning, anti hair wrap brushroll designed to pick up more hair from carpets and hard floors.
• Matrix Clean takes multiple grid passes, and Recharge and Resume picks up where it left off.

Good to know

• No suction figure or runtime appears in the listing, which makes direct comparison difficult.
• Vacuum only, with no mopping, and a bagless bin has to be tipped out by hand.

In its favour

• Bagless base holds 90 days of debris, and can switch to bagged mode if you prefer.
• Boosts suction on carpet automatically when the mop is removed.
• dToF lidar works in darkness, and PSD sensors detect objects as close as 4 cm.

Good to know

• When mopping it avoids carpets completely, so rugs need a separate vacuum run.
• The listing does not give base station dimensions.

In its favour

• 2.85 inch (7.2 cm) body reaches under desks, beds and low furniture where taller robots stop.
• Auto-empty station with a 3 L bag that needs replacing about every 60 days, says eufy.
• Edge expansion brush helps clean corners and improves coverage.

Good to know

• 4,000 Pa suction is far below the flagship models here, and no mopping is described.
• Navigation is described as point laser and multi-infrared, with no AI camera for object recognition.

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

• 200 minutes and up to 230 m² per charge, so a flat is easily covered in one run, per the listing.
• Bagless 4 L base holds up to 90 days and needs no spare bags.
• Quiet mode runs as low as 65 dB, according to Proscenic.

Good to know

• Small 300 ml dustbin and 200 ml water tank in the robot itself.
• The listing lists only three suction and water levels, fewer controls than some rivals.

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.
