Like all geeks I love gadgets, and I was thinking it could be cool to get one of those robotic vacuum cleaners you often see advertised in stores or on the Web. However, based on many reviews I’ve read, I believe the time to get rid of the old manual upright vacuum cleaner has not yet come. Let’s take a look at two of the main crawling cleaner lines today.
The iRobot Roomba, pictured above, possibly the most well-known item in this category. Unfortunately it seems to have harder to clean parts and a certain “dumbness”: it works around a room, changing direction when it bumps into a wall or other obstacle, but without really “knowing” where it’s going (it uses simple movement algorithms like spiraling, wall following and random walk). The result is the cleaned surface is not going to be homogeneous at all times. Newer generations also try to detect a recharge station via an infrared sensor and go to it to recharge themselves, if they find it. These come at around $160 to $200.
The Electrolux Trilobite, which seems to be smarter than the Roomba in that it employs ultrasonic and infrared sensors, and maps rooms to know where it has cleaned and where it has not. It can also return to its recharging station more effectively than the Roomba (having mapped its location), and has removable and more easily cleanable parts. However, sharp corners may give the built-in radar some headaches, and the added artificial intelligence comes at a price of around $1800, ten times the Roomba price.
Both kinds apparently have batteries that don’t last overly long before they need to be recharged, but their biggest problems are they don’t fit into corners (both being round), they take quite longer than a human would to vacuum clean a floor (making battery duration an issue) and they don’t always cover all the surface they should. They’re also as noisy as a regular vacuum cleaner, so you wouldn’t use them while sleeping at night, but rather when you’re out doing something else.
In short, I think I’ll stick to old-fashioned, “analog” upright vacuum cleaners and brooms, until something more reliable, efficient and maybe cheaper comes out. Or I might invest in an expensive upright Dyson one day. Any thoughts?
