While robot vacuums are fantastic in keeping your floors clean but they aren't able to substitute for a larger vacuum. Even the best vacuums struggle to get deep into carpets or rugs, and can often get caught in cords and socks.
Maintaining a regular schedule of maintenance (replacing filters, cutting tangled hair from brushes and emptying the dust bin) will make your robot last longer.
Battery Life
most expensive robot vacuum robot vacuums are able to handle a few cleaning sessions without having to be charged. The Ecovacs Q30S Combo is the runner-up of our top picks. It has batteries that last up to 180 minute (3,230 square feet) on a single charge. That amount of runtime is more than enough time to clean smaller homes with carpets that are hard and carpets with low pile or a bigger home with rooms that are roughly the same size.
A longer battery life also means that the robot is able to spend more time cleaning, and less time charging on its dock. It's worth opting for an auto-emptying dust bin, since those models are more efficient in cleaning up debris and returning to the dock for charging. It is important to clean or replace filters and clean the sensors and camera on a regular schedule so they can be seen clearly.
Smart mapping technology is a great feature to look for because it allows you to program your robot to only clear certain rooms or areas where it's more likely to bump into furniture or other obstacles. It's also helpful for ensuring your robot is able to get under and around sofas, beds and other furniture that is tall. A few robovacs are cheap and have boundaries that you can put on the floor to block off areas while others use cameras and sensors to achieve this goal.
Even the most powerful robot vacuums can't replace a conventional vacuum for heavy-duty, large-pile dirt and debris. It's best to keep an electric vacuum in your home for these tasks and schedule robot vacs for light cleanings throughout the week.
Navigation
A robot should be able to navigate your home without getting stuck or crashing into things like metal screws, loose pet hair, or sand. In our tests, we use a tracking device to track the robot as it travels through a multiroom lab and shows its surroundings. We also check how well the robot avoids obstacles like power cords, furniture leg, and pet waste.
The top robots are able to map out multiple floors, and recognize landmarks like windows and doors. The most advanced robots such as the Roborock S8 Pro Ultra have a dual sensor navigation system which uses a LIDAR to create a floor plan and a structured-light camera mounted on the front to detect objects in real-time. The S8 is able to avoid obstacles like power cords as well as legs of furniture. It also has the ability to store up to four floor maps.
The majority of the models that are affordable use bump sensors, which aren't as precise. In my testing they cut right through dog poop, cords, and even the shoes that were placed in the middle of the room. The best value pick the Dreametech D10+, is an exception to this. It has excellent carpet and hard floor pickup, excellent tangle and hair pickup, and a near perfect auto empty score.
Another feature worth mentioning is a large onboard dustbin that doesn't require manually emptied, and for models that mop, a water tank that can last for weeks of mopping sessions. The Karcher RCV 5 has this and a big enough footprint that it can go under furniture, but not so large that it can't fit into the space between your bathtub and toilet.
Apps
Robot vacuums are like upright robotic vacuums, and it takes lots of technology to bring them up to speed. There are many options in a market that is a mature. But even the top models still require some interaction with their users, particularly when cleaning schedules are being planned and establishing a floor plan and establishing virtual barriers.
To lessen the chance of this interaction, consider looking for a model that has its own app to determine the design of your home and save those settings for future use. This will allow the robot vacuum to continue where it began on subsequent runs rather than having the mapping process restarted each time.
It is also recommended to look for models that offer zone or spot cleaning. You can instruct the robot vacuum cleaner to focus on a specific area, for example, under the table after a huge family meal. You can do this using the app or voice commands.
Object avoidance is another feature that's included in many models. It lets the robot see something in its path, for instance the shoe box or a crate of dog toys, and guide itself around it. This prevents it from running into things that might damage its sensors or cause jams.
Some of the more expensive models we've tested come with this feature. However, they usually rely on bump sensors for this, and they weren't always able to stay clear of things in my test homes.
Pet Hair
Look for the best vacuum cleaner designed to pick up hair from pets. The most effective models come with powerful suction capabilities, a brush that avoids getting caught in a knot, and an emptying mechanism that will automatically empty hair into the trash bin when necessary. Some are also able to detect dirt levels and adjust the cleaning intensity accordingly. They are able to detect objects that aren't a part of your home's flooring like furniture, toys, food bowls cords, and much more.
Some robot vacuums come with extra pet-friendly features. These include a water dispenser that is used to mop floors, and a HEPA filtering system that eliminates allergens like pet dander. They may also offer the option of a quieter operation, which will reduce the amount of noise generated during cleaning sessions.
Robot vacuums with maps are a great option for pet owners, as they're designed to evaluate your home and create plans of attack according to the layout and obstacles in each room. For instance, the Shark Matrix Plus 2-in-1 Robot Vacuum is a smart vacuum that has the impressive capability to map rooms and navigate around furniture and other obstructions using accelerometer and gyroscope sensors that work together to learn the layout of your home.
Other advanced models allow you to define no-go zones that are areas that the robot is meant to stay clear of, such as fragile items or pet feeding spots--by adjusting settings via an app. This feature can be especially beneficial for families with a lot of activity because it allows you to schedule cleaning time and make adjustments without having to be in the same room as the vacuum. Spot cleaning is an additional fantastic feature. You can direct the vacuum cleaner to clean a spot that is particularly filthy or is brimming with pet hair.
Dust Bin
If you don't need something tiny, choose a robot with a large bin, or even a self-emptying bin. We recommend picking a model that has a large bin or a trash bin that automatically emptys. The former will help you keep up with emptying the bin often enough to ensure you are on top 5 robot vacuum of its performance and the latter will help you save time and effort by automatically dumping the contents into an internal bin every few cleanings.
Look for models that have smart mapping capabilities, which allow them to "learn" the layout of your home and plan more efficient routes. They can also sense and avoid objects that could hinder their routes (like shoelaces or tangled charging cables). Find models with intelligent mapping capabilities, which allow them to "learn" the structure of your home and devise more efficient routes, as well as ones that can sense and avoid objects that could hinder their routes (like shoelaces or strangling charging cables).
Some models also provide spot cleaning, which allows users to select specific areas of your home for intense cleaning. We've discovered that many of the top performers in our tests are able to pick up fine particles like baking soda and sand, along with heavier debris like oatmeal orzo pasta, metal screws and pet hair.
According to the brand, robots can last years and continue to perform well as long as they're maintained. For instance, cleaning tangled hair out of brushes, emptying dust bins after each use, and wiping cameras and sensors down as needed. The most reliable robots are more modular. This allows you to repair or replace parts such as wheels and batteries as they wear out.
