How Do Roomba Robot Vacuum Cleaners Work?

The machine bumps around the floor like a slow-motion ping-pong ball, changing direction when it encounters an object or obstacle. As a result it took a long 91 minutes to finish its cleaning cycle in our test room. For a dependable, versatile, and affordable cleaner, we prefer a bagless upright, but we have recommendations for other types of vacuums as well. We also tested the EcoVacs T8 AIVI, which did not avoid any objects. It just informed us in the app, after the session was over and the Nutella smeared everywhere, that there were many objects on our floor and that we should pick them up.

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.

Introduced in September 2002, the first-generation Roomba had three buttons for room size. The first-generation units comprised the original silver-colored Roomba, the blue Roomba Pro, and the maroon Roomba Pro Elite. The later two models included additional accessories, but all three used the same core robot and cleaning system. Roombas are driven irobot vacuum cleaner by two independently-operating side wheels, which can drive the Roomba forwards and backwards as well as perform turns of any radius, including 360° turns in place. Rotary encoders on the wheels can detect the rate at which the wheels are spinning so it can determine if they’re slipping or stuck, and drop sensors detect if a wheel is too low .

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 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.
