The robotic vacuum category has long been defined by a quiet technological arms race. For years, one of the most visible battlegrounds was navigation: how a robot finds its way around a home, builds a mental map of rooms, and decides where to clean. For much of that history, iRobot’s Roomba line relied on a camera-based system, while many competitors adopted lidar — light detection and ranging — which uses laser pulses to measure distances and construct precise floor plans. The debate over which approach was superior raged in enthusiast forums and review sections alike. Now, with a single announcement, iRobot has effectively ended that debate on its own terms.
In 2025-03, iRobot unveiled eight new Roombas, a release the company itself describes as the largest product launch in its history. The headline feature is not just the sheer number of devices, but the introduction of lidar mapping technology to the Roomba lineup for the first time. This is a significant shift. Lidar has been a staple among most of iRobot’s competitors for years, and its absence from Roombas was frequently cited as a drawback by reviewers and users who wanted faster mapping and more granular control over cleaning sessions. By adopting lidar, iRobot is not merely catching up; it is aligning itself with the current industry standard, which should translate into tangible benefits for consumers.
What does lidar actually change for the end user? The most immediate difference is mapping speed. According to the source material, the technology promises faster mapping. Older camera-based systems could take several cleaning cycles to build a reliable map of a home, sometimes getting confused by changing light conditions or moving objects. Lidar, by contrast, sweeps a laser beam around the room, measuring distances in real time. This allows the robot to construct a map much more quickly, often in a single pass. For a household that wants to set up the robot and start issuing room-specific commands right away, this is a meaningful upgrade.
Beyond speed, lidar enables a suite of features that have become expected in premium robot vacuums. The source material specifically mentions room-specific cleaning, which allows users to instruct the robot to clean only the kitchen or only the bedrooms, rather than the entire floor plan. It also mentions the ability to create clean zones and keep-out zones directly in the app. A clean zone might be an area that needs extra attention, such as the space in front of a pet’s food bowl. A keep-out zone might be a play area with small toys or a spot with tangled cables that the robot should avoid entirely. These features were previously available on many competitor models but were not part of the Roomba experience at this level. Now they are.
The source material also notes that iRobot has started publishing suction power specifications for its robots. This is another notable change. Historically, iRobot was somewhat opaque about raw suction numbers, preferring to talk about cleaning performance in broader terms. Competitors, particularly brands like Roborock and Ecovacs, have long advertised specific Pascal (Pa) ratings. By publishing these figures, iRobot is giving consumers a more direct way to compare models across brands. The source material cites a specific example: the Roomba Max 715 Vacuum Robot + Auto Empty Dock, priced at $699.99, which updates the Roomba Max 705 (previously $899.99) with increased suction power — 30,000Pa, up from 13,000Pa — and a lower price. That is a substantial jump in raw power, and the price drop makes it a more compelling proposition.
Another interesting detail from the source material concerns the physical design of the new robots. The midrange Roomba Plus 575 Combo Robot + AutoWash Dock, priced at $799.99, replaces the Roomba 505 (which was $999.99). The 575 is almost half the size of its predecessor, thanks to a new dual-lidar sensor. iRobot’s chief engineer and vice president Adam Pope told The Verge that this new technology enabled them to fit more tech into a smaller space. With 9 cm of clearance and a narrower width, the 575 should more easily fit under furniture and cabinets. This is a practical consideration for many homes where low-clearance sofas and bed frames are common. A smaller footprint also means the robot can navigate tighter spaces, such as between chair legs or into narrow alcoves.
The higher-end models also benefit from the lidar shift. The source material indicates that for the higher-end models, lidar should mean faster mapping and more agile navigation. This suggests that the top-tier Roombas will not just be more powerful in terms of suction, but also more efficient in how they move through a space. Agile navigation is not just about speed; it is about avoiding obstacles, not getting stuck, and covering the floor in a logical, systematic pattern rather than a random bounce. The source material also mentions that both the Roomba Plus 575 and the Roomba Max 715 have Roomba’s signature dual rubber roller brushes with anti-tangle tech, along with lidar navigation and AI-powered obstacle detection. The anti-tangle tech is particularly relevant for pet owners, as hair and fur are common culprits for jammed brushes.
There is also a new iRobot app. The source material states that the company is launching a new app that adds a real-time cleaning view aided by lidar. This means users can watch the robot’s progress on a live map as it cleans, seeing which rooms it has covered and where it is currently working. This is a feature that many competitor apps have offered for years, and its arrival on the Roomba platform is a welcome addition. Real-time views are not just a novelty; they provide peace of mind, especially when the robot is cleaning while the homeowner is away or in another room.
The source material also provides context on why iRobot made this change now. In an interview with The Verge, a company representative named Fernandez said that iRobot had been evaluating lidar technology for some time and decided to make the switch because they believe lidar is finally mature enough and affordable enough to fit into their product roadmap. This is an important admission. It suggests that iRobot was not opposed to lidar on principle, but rather was waiting for the technology to reach a point where it could be integrated without compromising on cost or reliability. That time has now come. For consumers, this means that lidar-equipped Roombas are available across a range of price points, not just on the flagship models.
One more detail worth noting from the source material: the Roomba 775 has a retractable mop cover. This is a design feature that allows the mop pad to be lifted or covered when not in use, preventing it from dragging on carpets or rugs. This is a common issue with combo vacuum-mop robots, where the mop can inadvertently wet carpeted areas. A retractable cover is a thoughtful solution that adds versatility, allowing the robot to transition from hard floors to carpets without requiring the user to manually remove the mop pad.
Practical steps
If you are considering upgrading to one of the eight new Roombas, or if you are simply curious about what lidar brings to the table, there are several practical steps you can take to make the most of the new technology.
First, assess your home’s layout and your cleaning habits. Lidar mapping is most beneficial in homes with multiple rooms, distinct zones, or areas that you want to exclude from cleaning. If you live in a small studio apartment, the benefits may be less pronounced, but you will still benefit from faster mapping and the ability to set keep-out zones around cables or delicate items. Take a mental inventory of your floors: where are the rugs, where are the hard floors, and where are the areas you never want the robot to go? This will help you configure the app once you set up the robot.
Second, when you unbox your new Roomba, give it time to complete an initial mapping run. The source material indicates that lidar enables faster mapping, but it is still a process. Do not interrupt the first cleaning cycle. Let the robot explore the entire accessible floor plan. This initial map will serve as the foundation for all future commands. If you have multiple floors, you will likely need to run the mapping process on each floor separately. The robot will store these maps, and you can switch between them in the app.
Third, after the initial map is created, spend some time in the app to set up clean zones and keep-out zones. This is where lidar really shines. Identify areas that need extra cleaning, such as the space around a dining table or a high-traffic entryway, and mark them as clean zones. Conversely, mark areas that the robot should avoid, such as a pet’s water bowl, a child’s play mat, or a tangle of charging cables. The source material specifically mentions the ability to create these zones in the app, so this is a core feature of the new system.
Fourth, take advantage of the real-time cleaning view. The new iRobot app adds a live map that shows the robot’s position and progress. Use this feature during the first few cleaning sessions to monitor how the robot navigates. If you notice it struggling in a particular area, such as getting stuck under a low piece of furniture or hesitating near a threshold, you can adjust the keep-out zones accordingly. The real-time view is not just for entertainment; it is a diagnostic tool that helps you refine the robot’s behavior.
Fifth, pay attention to the suction power specifications. Now that iRobot is publishing these numbers, you can make more informed comparisons. The source material cites the Roomba Max 715 with 30,000Pa of suction, up from 13,000Pa in the previous model. If you have wall-to-wall carpeting or pets that shed heavily, higher suction is likely worth the investment. If you have mostly hard floors, a lower-suction model may be sufficient, and you can save money. The key is to match the robot’s capabilities to your actual cleaning needs.
Sixth, consider the physical dimensions of the robot. The source material highlights that the Roomba Plus 575 is almost half the size of its predecessor, with 9 cm of clearance. Before purchasing, measure the clearance under your furniture. If you have low sofas or beds, a slimmer robot will be able to clean under them, which is a significant advantage. A narrower width also helps in tight spaces. If your home has many obstacles, such as chair legs or narrow doorways, a smaller robot will navigate more easily.
Seventh, if you are upgrading from an older Roomba, be prepared to set up the new app from scratch. The new app is a separate launch, and you will likely need to create a new account or link your existing one. The source material does not specify migration details, so it is best to assume a fresh setup. This is a minor inconvenience but worth it for the new features.
Eighth, if you have a combo vacuum-mop model like the Roomba Plus 575, familiarize yourself with the AutoWash Dock. The source material mentions that the dock washes and dries the mop after use with hot water and hot air. However, it also notes that you need to drain, clean, and refill the water tank. This is a maintenance task that you will need to perform regularly. Factor this into your routine. The convenience of an auto-washing dock is offset by the need to manage the water supply.
Ninth, if you are considering the Roomba 775 with the retractable mop cover, think about your floor types. The retractable cover is designed to lift the mop pad when the robot is on carpet, preventing it from getting wet. This is a useful feature for homes with a mix of hard floors and rugs. If your home is entirely hard floors, the retractable cover is less critical, but it is still a nice feature to have.
Tenth, keep an eye on firmware updates. The source material does not specify a release schedule, but iRobot has historically pushed updates to improve navigation and add features. After setting up your new Roomba, check the app periodically for updates. Lidar-based systems can be refined over time, and firmware updates may improve mapping accuracy or add new zone options.
Common mistakes to avoid
The transition to lidar is a significant change for iRobot, and there are several common mistakes that users might make when adopting the new technology.
One mistake is assuming that lidar eliminates the need for preparation. While lidar is more accurate than older camera systems, it is not magic. The robot still needs a clear path to navigate. Do not leave loose cables, small toys, or clothing on the floor and expect the robot to avoid them. The source material mentions AI-powered obstacle detection on some models, but it also notes that other robots in the market have a tendency to get stuck on laundry, bath mats, and other obstacles. The new Roombas have obstacle detection, but it is not infallible. Clear the floor of obvious hazards before starting a cleaning cycle.
Another mistake is ignoring the keep-out zone feature. With lidar, you have the ability to mark areas that the robot should avoid. If you do not set these zones, the robot will attempt to clean everywhere, including areas where it might get stuck or cause damage. For example, if you have a rug with long fringes, the robot might get tangled. If you have a pet’s water bowl, the robot might knock it over. Take the time to set up keep-out zones during the initial setup. This is one of the primary benefits of lidar, and failing to use it is a missed opportunity.
A third mistake is not understanding the difference between clean zones and keep-out zones. A clean zone tells the robot to focus extra attention on a specific area. A keep-out zone tells the robot to avoid an area entirely. Some users confuse the two and end up with the robot avoiding the very areas they wanted cleaned. Read the app instructions carefully. The source material explicitly mentions both features, so they are distinct and should be used appropriately.
A fourth mistake is neglecting the maintenance of the AutoWash Dock. The source material is clear that the dock washes and dries the mop, but it also requires manual intervention: you need to drain, clean, and refill the water tank. If you ignore this task, the dock may stop functioning properly, or the mop may not be cleaned effectively. Set a reminder to check the water tank regularly. The convenience of an auto-washing dock is real, but it is not a zero-maintenance solution.
A fifth mistake is overestimating the suction power. The source material cites 30,000Pa for the Roomba Max 715, which is a high number. However, suction power is not the only factor in cleaning performance. The brush design, the seal of the vacuum, and the navigation pattern all matter. Do not assume that a higher Pa rating automatically means better cleaning. Read reviews and consider your specific floor types. The source material notes that the Roomba Max 715 has dual rubber roller brushes with anti-tangle tech, which is a good feature, but it is the combination of suction and brush design that determines effectiveness.
A sixth mistake is ignoring the size of the robot. The source material highlights that the Roomba Plus 575 is almost half the size of its predecessor, with 9 cm of clearance. If you have furniture with low clearance, this is a major selling point. However, if you have very high-pile carpets, a smaller robot might have difficulty climbing over them. The source material does not specify the climbing ability of the new models, so it is best to check the specifications before purchasing. Do not assume that a smaller robot is universally better; it depends on your home.
A seventh mistake is expecting immediate perfection from the mapping system. While lidar is faster than camera-based systems, the first mapping run may not be perfect. The robot might miss a corner or misinterpret a room boundary. The source material does not specify how many runs are needed for a perfect map, but it is reasonable to expect that the map will improve over time. Do not be frustrated if the first map is not flawless. Let the robot run a few cleaning cycles, and the map should become more accurate.
An eighth mistake is forgetting to update the app. The new iRobot app is a key part of the lidar experience, as it provides the real-time cleaning view and the zone controls. If you do not update the app, you may miss out on new features or bug fixes. The source material does not specify a release schedule for updates, but it is a good practice to check for updates regularly.
A ninth mistake is buying a model with more features than you need. The eight new Roombas span a range of prices and capabilities. The source material mentions the Roomba Plus 575 at $799.99 and
