# iRobot Roomba models compared: Combo, j series and s9+ Source: https://dockandmop.co.uk/best/irobot-roomba-models-compared 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 iRobot's lineup now spans two generations. The older j7, j7+ and s9+ are vacuum-only robots that rely on a camera or sensors, with a Clean Base on the plus models to empty the bin. The newer Roomba Combo and numbered models (205, 505, 705) add mopping and ClearView LiDAR, and the higher ones sit on an AutoWash Dock that washes and dries the mop as well as emptying debris. So the useful questions are simple: do you need a mop at all, do you want the robot to clean its own mop, and how much do you care about it steering round cables, socks and pet mess? iRobot does not quote suction in Pa, so this comparison sets that aside and focuses on the mop, the base, avoidance, navigation and runtime, using only the details each Amazon listing gives. ## 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. iRobot Roomba Combo 10 Max Robot Vacuum and Mop + AutoWash Dock - Multi-Functional Base, Refills Bin, Washes & Dries It's Pad, Self-Emptying, Auto-Retract Pad, Avoids Obstacles Suction: Not stated; Mop on carpet: Retracts to top of robot; Main brush: Dual rubber brushes; Dock: AutoWash, self-empty, refill, pad wash and dry; Runtime: Not stated The best answer to wet rugs here: the Auto-Retract Mopping System lifts the pad right up onto the top of the robot. Dual rubber brushes resist pet hair tangles on carpet. In its favour: - Auto-Retract Mopping System lifts the pad to the top of the robot, so carpets stay dry, according to iRobot. - Dual Rubber Brushes avoid pet hair tangles while strong suction pulls embedded dirt from carpet. - AutoWash Dock empties debris, refills the tank, and washes and dries the pad. Good to know: - The listing gives no suction figure in Pa, so raw power is hard to compare. - Runtime is not stated in the listing, so coverage per charge is unclear. ### 3. 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. ### 4. iRobot Roomba Max 705 Combo Robot Vacuum & Mop + AutoWash Dock – Extending self-cleaning Roller Mop, Retractable Cover, Dual Brushes, Self-empties, Heat-Washes & Dries, Avoids Obstacles, LiDAR (White) Suction: 13,000 Pa; Anti-tangle: Dual rubber brushes; Auto-empty: Up to 75 days; Mopping: PowerSpin roller, heated; Runtime: Not stated PrecisionVision AI recognises pet waste, socks and cords and steers round them, a real plus with a puppy in the house. Dual rubber brushes handle fur and the AutoWash Dock gives up to 75 days of auto-emptying. 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. ### 5. iRobot Roomba j7 Wi-Fi Connected Robot Vacuum - Identifies and avoids Obstacles Like pet Waste & Cords, Smart Mapping, Works with Alexa, Ideal for Pet Hair, Carpets, Hard Floors Mop type: No mop; Base or dock: Charging base only; Obstacle avoidance: PrecisionVision camera; Navigation: Smart Mapping; Runtime: 75 minutes The j7 has the same PrecisionVision obstacle avoidance as the j7+, with Dirt Detect and dual rubber brushes, but no self-emptying base. Suits smaller homes where emptying the bin by hand is fine. In its favour: - PrecisionVision Navigation spots hazards such as pet waste and charging cords in real time - Dual Multi-Surface Rubber Brushes flex to floor type and resist pet hair tangles - Spot cleaning lets you send it to one area, such as in front of the kitchen counter Good to know: - 75 minute runtime is short for larger homes, and there is no mopping - No self-emptying base included, so the bin must be emptied after runs ### 6. iRobot Roomba s9+ (9550) Robot Vacuum with Automatic Dirt Disposal- Empties Itself, Wi-Fi Connected, Smart Mapping, Powerful Suction, Anti-Allergen System, Corners & Edges, Ideal for Pet Hair, Black Mop type: No mop; Base or dock: Automatic dirt disposal; Obstacle avoidance: Not stated; Navigation: Smart Mapping (details not stated); Runtime: Not stated The s9+ is an older vacuum-only Roomba with automatic dirt disposal, smart mapping and an anti-allergen system. Its listing is thin, so it suits buyers who already know the model. In its favour: - Automatic dirt disposal means the robot empties itself into its base - Listing mentions powerful suction and an anti-allergen system with a HEPA filter - Stated cleaning path width of 35.1 cm, aimed at corners, edges and pet hair Good to know: - Obstacle avoidance, runtime and navigation type are not stated on this listing - Vacuum only with no mopping, unlike the Combo models in this guide As an Amazon Associate we earn from qualifying purchases.
