Robot vacuums can be great to keep your floors clean however they aren't a replacement for a traditional vacuum. Even the most advanced robots have difficulty getting deep into carpets and rugs and they can become tangled with cords and socks.

Maintaining a regular schedule of maintenance (replacing filters cutting hair tangled from brushes and emptying the dust bin) will make your robot last longer.
Battery Life
Most robot vacuums can handle one or two cleaning sessions before needing to recharge. The runner-up of our top picks is the Ecovacs Deebot Q30S Combo is rated to last up to 180 minutes (3,230 square feet) of cleaning time on a single charge. This will be more than enough for the majority of small homes with a mixture of hard floors and carpets with low pile or larger homes where the rooms are about the same size.
A longer battery lifespan also means that the robot is able to spend more time cleaning, and less time charging on its dock. It's recommended to select a model with a self-emptying dust bin, as they are more efficient in picking up debris and returning to the dock to recharge. It is essential to clean or replace filters and clean the sensors and the camera regularly so that they can see clearly.
Smart mapping technology can be a valuable feature, as it allows you to program your robot to ensure it only cleans specific rooms or avoids areas where it's likely to crash into furniture and other obstacles. It's also beneficial for ensuring your robot is able to get under and around sofas, beds and other furniture with a high height. Some cheap robovacs come with boundary strips you can use to block certain areas. Other high-end models depend on sensors and cameras.
Even the best robot vacs aren't able to replace a traditional vacuum for heavy-duty large-pile dirt and debris. It's wise to keep a standard power vac in reserve for those tasks and to schedule robot vacuums regularly for cleaning up light chores throughout the week.
Navigation
A robot should be able to navigate around your home without getting stuck or crashing into objects like metal screws, loose pet hair, or sand. In our tests we used a tracking device used to track the robot through the multi-room lab. It then analyzes its surroundings. We also look for the extent to which it can avoid obstacles like furniture legs, power cords and pet waste.
The most advanced robots can create several floors and recognize landmarks, like doors and windows. The most advanced robots, such as the Roborock S8 Pro Ultra have a dual sensor navigation system which utilizes an LIDAR to draw a room's layout and a structured-light camera on the front to detect objects in real-time. The S8 can avoid obstacles such as power cords and furniture legs. It also has the ability to store up to four
automatic floor cleaner maps.
The majority of the models that are affordable depend on bump sensors that are not as accurate. In my testing they were able to rip through dog poop, cords, and even the shoes that were placed in the middle of the room. The most affordable choice the Dreametech D10+, is one exception to this. It has excellent carpet and hard floor, tangle and hair pickup. It also has an auto empty score that is near-perfect.
A large dust bin onboard, which does not need to be emptying manually, is also a feature that's important. If you have models that mop the floor, this water tank is able to hold enough water for several weeks of cleaning. Karcher's RCV 5 is an excellent illustration of this. It has a large enough footprint to be able to be placed under furniture, but not too big that it cannot fit in the space between your toilet and tub.
Apps
Robot vacuums are similar to their upright counterparts and require lots of technology to keep them up-to-date. The result is a mature market with plenty of options. But even the best models require some interaction with their users - particularly when cleaning schedules are being planned, establishing a home floor plan, and setting up virtual barriers.
Think about a model that has its own app that can recognize the layout of your home and save these settings for future use. This will let the vacuum start where it left off in subsequent runs, without having to start the mapping process every time.
It's also worth keeping an eye out for a vacuum that comes with zones or spot cleaning options. You can tell the robot vacuum cleaner to focus on an area, like under the table after a huge family meal. You can typically do this via the app or via voice commands.
A lot of models also offer object avoidance. It lets the robot detect objects in its path, such as the shoe box or a crate filled with dog toys, and then guide itself around it. This prevents it from crashing into objects that could harm its sensors or cause jams.
Some of the more expensive models in our tests include this feature. However, they usually rely on bump sensors for this and weren't always able to stay clear of things in my test homes.
Pet Hair
Find an upright vacuum cleaner specifically designed to collect pet hair. The
best robot hoover models have powerful suction capabilities, a brush that avoids the tangling and an emptying mechanism that will automatically dump hair into the trash bin when necessary. Some models can also determine dirt levels and adjust the cleaning intensity according to the amount of dirt. They can also detect objects that aren't part of your home flooring, like toys, furniture and food bowls.
Certain robot vacuums come with features that are pet-friendly, such as a small water dispenser that can be used for mopping floors and an HEPA filter that can reduce allergens like pet dander. They may also have a quieter mode of operation to minimize the amount of noise produced during cleaning sessions.
Robot vacuum Cleaner cheap vacuums that have mapping capabilities are a great option for pet owners. They are designed to analyze your home and develop an attack plan based on the layout of each room as well as obstacles. Shark Matrix Plus is a dual-purpose robot vacuum that can create a map of a room, and navigate around furniture, and other obstacles using accelerometer and gyroscope sensors.
Apps allow you to set up zones that are not allowed. These are areas where the robot should not be permitted, such as areas that contain delicate items or pet feeding areas. This feature is especially useful for families with busy schedules, since you can schedule cleaning times without having to be present in the space where the vacuum is. Spot cleaning is an additional excellent feature. You can direct the vacuum cleaner to clean an area that is particularly dirty or filled with pet hair.
Dust Bin
If you don't need something small, consider a robot with a large bin or even a self-emptying trash bin. That's why we recommend opting for a model with a large bin, or perhaps self-emptying bins. The former will help you keep up with emptying the bin often enough to ensure you are on top of its performance and the latter will help you save time and effort by automatically dumping the contents into an internal container every few cleans.
Find models that have smart mapping capabilities, which enable them to "learn" the layout of your home and plan more efficient routes. They also can detect and avoid objects that could block their paths (like shoelaces or tangled charging cables). Find models with intelligent mapping capabilities. This lets them "learn the layout of your house and plan an efficient route.
Certain models also offer spot cleaning, which lets you to manually target a particular area of your house for intensive cleaning. In our tests, we discovered that the top models are able to remove fine particles such as baking soda, sand, orzo, screws made of metal and pet hair, as well as heavier debris such as oatmeal, orzo, and screws made of metal.
According to the manufacturer, robots can last years and perform well as long as they are properly maintained. For example cleaning hair tangled of brushes cleaning dust bins after each use as well as wiping cameras and sensors down as required. The
best robot hoover-performing robots also tend to be more modular which makes them simpler and less costly to repair or replace parts such as wheels and batteries when they wear out.
