(We like to call them bump-and-run bots.) That’s fine for cleaning three or four rooms per session (or a little more if you’re patient), though the bumbling aimlessness gets on some people’s nerves and makes such models inconsistently effective at tidying larger areas. IRobot also sells a few models that are very similar to the Roomba i4 EVO and are worth buying instead if you find them on sale, including the iRobot Roomba i3 EVO and Roomba i3+ EVO (with dock), which are identical to the i4 EVO and i4+ EVO but have smaller batteries, and the older Roomba 900 series.Ĭheaper robots usually have semi-random navigation systems. The downside is that it doesn’t work quite as fast as some competing models.Īnother neat option: The iRobot Roomba i4+ EVO adds a charging dock that automatically sucks the debris out of the robot and stores it in a disposable bag.
You can remotely turn the robot on or off and optionally set an automatic cleaning schedule. It’s also better at cleaning rugs than most other bots, and hair doesn’t get tangled in its brushes as quickly. The Roomba i4 EVO is sturdy and repairable-you can reasonably expect to own it and use it regularly for years. It also has smart mapping, so you can tell it to clean or avoid specific rooms. The iRobot Roomba i4 EVO works well in most homes, large or small, because it drives in orderly, back-and-forth rows, keeping track of where it has or hasn’t been, so that it doesn’t miss any big patches of flooring.
