About Smart VacuumsThere are those of us who clean once a week, and there are those of us who clean when the in-laws come to visit. The appeal of the robotic vacuum reaches both camps: Either way, the house is a bit more spotless with minimal human input. Today's robotic vacuums are a far cry from the first models that you had to track down, stranded somewhere in your house, by their melancholy, "I'm out of power" beeping. The latest products clean your house, remember the layout to increase efficiency, dump their own dirt in a receptacle and find their way back to the charging station so they can juice up. |
SizeThe dimensions of a robot vacuum matter for a couple of reasons. First, they will determine how well it can get into tight spots, such as under your kitchen cabinets and low-clearance furniture (couches and recliners). If it’s too tall, it won’t be able reach into these spots, or worse, it will get in and get stuck until physically free it. Second, the bigger the robot vacuum, the larger the dustbin. Robot vacuums don’t use expandable bags like many of their stand-up brethren do, so when it comes to debris capacity, what you see is what you get. There is no sweet spot for robot vacuum dimensions that we could determine—it really depends on your particular room layout—but a diameter of 13- to 14 inches and a height of 3.5 to 4 inches are the most common measurements we encountered. Wi-FiWi-Fi-enabled robot vacuums allow you to control them with a smartphone app instead of, or in addition to, a physical remote. That convenience alone doesn’t really warrant the extra cost these models command, but some model’s apps also provide other perks, such as detailed cleaning histories and the ability to save and edit floor maps for better navigation. Those models are worth considering if you’re cleaning large, intricate spaces. Features & FunctionsFundamentally, the robot vacuums in our guide all operate the same way: They autonomously maneuver around your home on a couple of wheels suctioning debris from your floors. Two to four brushes on the bottom—both rolling-style agitators and spinning side brushes—grab dirt from the floor and wall edges respectively, and guide it into the suction area or direct it straight to a small, filtered dustbin. When cleaning is complete, or their battery is running low, they return themselves to their charging dock. But just how they get the job done can differ across manufacturers and models. Here are some features and functions to consider beyond the basics. MappingManufacturers are increasingly including mapping capabilities in some of their robot vacuums. These models use an on-board camera or laser reflections to produce a 360-degree view of the room. This allows the robot vacuum to create a map of the space and locate itself within that map. The advantage of mapping is the vacuum will know which areas it has already cleaned and which it hasn’t, to avoid going over the same spot unnecessarily. It also lets it know where to resume cleaning if it must stop and recharge midway through the task. This makes it ideal for larger rooms and—because it’s still something of a premium feature—larger budgets. |
NavigationThe allure of robot vacuums is their promise to complete their task with minimal management from you. In order to do that, they must be able to navigate a room’s unique layout, maneuver around furniture and other obstacles, and avoid hazards such as falling down stairs and getting tangled in electrical cords. Robot vacuums “see” the world through a combination of sensors. Cliff sensors let it know when there is an increase in distance to the floor—e.g., stairs or a sunken living room—so it doesn’t tip over the edge. Other sensors tell it when it has bumped into an object, so it can change direction, or is near a wall, so it can follow it. Still other sensors help the robot vacuum track how far it has traveled. Depending on the manufacturer and model, a robot vac might also include sensors that determine the amount of dirt present so it can adjust its cleaning mode accordingly. Boundary BlockersIn an ideal world, you’d clear all your floors of clutter before using your robot vacuum. But we live in the real one and that’s not always possible or desirable. Knowing this, many robot vacuums include some way to block off areas you don’t want it venturing into, whether it’s a pet’s area, your kids’ room, or a cluster of device cords in the corner. Often it’s just a length of magnetic tape you stretch in front of or on a forbidden area that the vacuum’s sensors will detect and tell it to avoid. But some models employ virtual barriers, such as the ability to designate boundaries on a floor plan that signal the robot to steer clear. Choose From different Cleaning ModesJust as your stand-up vacuum can be adjusted to clean either carpet and hard flooring, so to can a robot vac. Most feature the ability to change suction and other cleaning functions to adapt to different floor surfaces, either automatically or with input from you. They may also have a spot mode for more concentrated cleaning on a small area (cleaning up a spill, for example), include options for single- and double-passes of a room, or offer an option to focus just on cleaning along wall edges and baseboards. Control Virtually, all models include an “automatic” mode that requires you to do nothing more than press a button on a remote, in an app, or on the vacuum itself to clean a room. This is great for ad-hoc cleaning, but most models can also be programmed to clean on a schedule. The latter scenario is great if you want them to work when you’re not home or to create a regular cleaning routine. Some higher-end models also integrate with smart speakers, such as the Amazon Echo and Google Home, which allows to control them using voice commands.
Smart Vacuums Are Not CheapSmart vacuums can cost as much as $1,000 at the high end, with many of the best models running no less than half that. When determining which ones are worth the expense, make sure to give a test drive before you buy it. |
