Cameras and optical sensors can help with obstacle recognition, and LiDAR-based navigation uses lasers to detect objects. These capabilities aren’t perfect, but vacuums are now more adept at finding their way back to charging docks than they were even a few years ago. Another new feature is self-emptying bins, which suck the debris out of the robot and into a canister in the charging dock. For example, I have several radiators in my house with a 3.5-inch clearance that slim vacuums can get under, while just-slim-enough models sometimes get stuck, and too-thick models bump up against and go elsewhere. If you want your robot vacuum to get under your low-clearance furniture, make sure you choose a model that is slim enough to do so. Whereas some robot vacuums sense carpeting and boost suction, the i3+ EVO provides consistently strong suction, and when it detects excess dirt, it automatically performs multiple passes.
This “smart mapping” tech is incredibly convenient, and one of the most compelling reasons to spend a little extra on a robot. They work and they’re useful, though fall a little short of life-changing. A self-emptying (or auto-emptying) robot vacuum comes with a big charging dock, which sucks debris out of the robot through a trapdoor in the dustbin, and stores it in a disposable irobot vacuum cleaner bag or bagless bin . Instead of emptying your bot’s bin after every cleaning session, you only have to empty the dock every month or two. The most noteworthy Roborock alternative is the Wyze Robot Vacuum. Wyze is known for selling good-enough and implausibly affordable smart-home gear like security cameras, locks, thermostats—and the laser-nav Wyze Robot Vacuum too.
While all of them have the ability to respond to virtual wall barriers, the company offers an additional device called the Dual Mode Virtual Wall that can create the virtual barriers to fence in a Roomba. Many robot vacuums are now smart, letting you start a cleaning session from an app or by asking a smart speaker. Some, like the iRobot Roomba s9+ Robot Vacuum, let you block off entire rooms in an app, so you don’t have to worry about them bissell crosswave cordless getting stuck on your kid’s clothing piles. A collection of smart sensors enhances the robot’s ability to maneuver obstacles and drive around furniture, as well as prevent it from accidentally tumbling down a flight of stairs. The robot vacuum will run up for up to 90 minutes before heading back to its charging station. All of this and more can be controlled via the iRobot Home App, where you’ll be able to easily schedule cleanings, too.
Bagless vacuums can potentially create problems for allergy sufferers when it comes time to empty the machine. The process can lead to some potentially sneeze-inducing dust clouds. According to Consumer Reports, HEPA (high-efficiency particulate air) filters can’t hurt – and they can help.
However, we still predict that Roomba bots on average will last longer than any of their competitors and work better at getting hair out of rugs. We haven’t tested the i3 EVO since its software was updated to include smart mapping, but when we do, we’ll report back with the dyson robot vacuum results. Most robot vacuums will get snagged on charging cables, which jam the brush roll or sometimes pull the bots off course. The key is that bots don’t procrastinate or get bored, so they spend more time cleaning, and clean more thoroughly, than almost any human.
