# Best robot vacuums for small flats Source: https://dockandmop.co.uk/best/best-robot-vacuum-for-small-flats Publisher: Dock and Mop. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://dockandmop.co.uk/how-we-pick In a small flat, the robot itself is rarely the problem. It is the dock. Full-size mopping stations hold clean and dirty water tanks, so they are bulky and need clear space either side, which is hard to find in a one-bed with a narrow hallway. The good news is that a flat rarely needs a huge battery either: almost any modern robot covers a few rooms on one charge, so you can put the focus on a compact base, sensible suction and lidar mapping that copes with tight doorways. This guide compares seven models for flats, from a Roomba that compacts dust inside the robot with no self-emptying station at all, through compact self-empty bases, to a small all-in-one dock that washes the mop. Each is compared on dock, runtime, suction, mopping and navigation, using the details in its Amazon listing. ## Products ### 1. iRobot Roomba® 205 DustCompactor Combo Robot - Vac + Mop - Auto Compacts Debris Within The Robot - No Emptying For 60 Days - Bagless - Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Dock: None needed: compacts debris inside robot; Runtime: Not stated; Suction: Not stated; Mopping: Microfibre pad, carpet detection; Navigation: ClearView lidar The space-saver of the group: the 205 crushes debris inside the robot so there is no separate self-emptying station, yet iRobot says it still goes up to 60 days without emptying. In its favour: - Onboard DustCompactor removes the need for a separate self-emptying station, and needs no emptying for up to 60 days. - Bagless design, so there are no bags to buy or store in a small flat. - ClearView lidar maps in neat rows even in the dark, and automatic carpet detection stops it mopping rugs. Good to know: - The listing does not state runtime or a suction figure in Pa (only 70x a Roomba 600). - Mopping is a simple pad with a micro-pump; there is no mop washing or drying. ### 2. XIAOMI H40 Robot Vacuum Cleaner with Self Empty Station, 10000 Pa Suction Dock: Compact 32.6 cm self-empty base, 4 L bag; Runtime: 100 minutes; Suction: 10,000 Pa; Mopping: Mop pad and water tank included; Navigation: LDS laser Xiaomi shrank the base to a compact 32.6 cm, which it says is 59% smaller than the previous generation, while the 4 L bag lasts up to 90 days. A tidy fit for a hallway or under a desk. 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. ### 3. Tapo RV30 Max Plus 5300Pa Robot Vacuum Cleaner with Mop,Auto Empty/Charging Dock: Auto-empty, 3 L sealed bag, up to 2 months; Runtime: 150 minutes; Suction: 5,300 Pa; Mopping: Adjustable water flow; Navigation: Lidar and IMU A sensible flat robot from Tapo with lidar and IMU mapping, 22 mm climbing and a self-emptying base with a sealed 3 L bag. The 3 year manufacturer warranty stands out. In its favour: - Self-empties into a 3 L sealed bag for up to two months, according to Tapo. - Climbs up to 22 mm, enough for most door bars between rooms. - Listing states a 3 year manufacturer warranty and a UK support line. Good to know: - 5,300 Pa suction is lower than most rivals here, best for hard floors and low to medium pile carpet. - The listing does not give the base station's dimensions, so check the space it needs. ### 4. Lefant Robot Vacuum and Mop, 12000Pa Suction, 90-Day Self-Emptying, Obstacle Avoidance, Auto Mop Washing&Drying, All-in-One for Pet Hair Carpet, 5G WiFi Alexa/APP/iWatch Control, M3 Dock: Self-empty 3.2 L bag, 45°C mop wash, air drying; Runtime: Up to 220 minutes; Suction: 12,000 Pa; Mopping: Auto mop washing and drying; Navigation: 360° lidar The M3 brings mop washing and drying to a base that Lefant says tucks neatly under cabinets. With 12,000 Pa and up to 220 minutes, it is the most capable mopper for a small kitchen. 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. ### 5. Lefant M2 Pro Robot Vacuum Cleaner with Mop — 90-Day Bagless Self-Emptying Dock: Bagless self-empty, 90 days; Runtime: 140 minutes; Suction: 6,000 Pa; Mopping: 300 ml tank, 3 flow levels; Navigation: dToF lidar Lefant's M2 Pro holds 90 days of debris in a bagless base, so there are no bags to store. dToF lidar maps in the dark and PSD sensors spot objects as close as 4 cm. 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. ### 6. iRobot Roomba® 505 Combo + AutoWash Dock Robot Vacuum Cleaner with Mop Function Dock: AutoWash, 75-day emptying, heated drying; Runtime: 120 minutes; Suction: Not stated; Mopping: DualClean pads, auto-lift on carpet; Navigation: ClearView Pro lidar A full washing dock from iRobot with mop pads that auto-lift on carpet and PrecisionVision AI that avoids cords, socks and pet waste. Worth the space if your flat has hard floors and a pet. In its favour: - AutoWash Dock gives 75 days of emptying, pad washing and heated pad drying. - Mop pads auto-lift when carpet is sensed, so rugs in a living room stay dry. - PrecisionVision AI recognises cords, socks and pet waste and steers around them. Good to know: - A washing and drying dock is bulkier than the compact self-empty bases here, and the listing gives no dock size. - No suction figure in Pa is given, only a comparison with older Roombas. ### 7.

A low-hassle pick if you never want to recharge mid-clean. 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.
