This is my review of iRobot Roomba 620 Vacuum Cleaning Robot.
We purchased the robotic cleaner to get underneath beds. It is effective in removing dust where a conventional vacuum cleaner cannot reach and lifting heavy furniture is a chore. It is good at detecting and avoiding toppling over the top of the stairs, which unfortunately it cannot vacuum. Carpets and tiled floors are left looking clean, although I am unsure how efficient this machine is. It takes a long time – 30 minutes or so – to clean an entire level of house or a flat, and often misses small areas. Does it waste electricity by going over some surfaces with unnecessary frequency, wearing out carpet in the process?
As an aside, it is entertaining to watch it in action. You may like to view the Youtube videos of a cool cat taking a ride on and apparently operating the vroomba as opposed to the dog which barks and growls at but steers well clear of this apparent alien being. It is worth checking there is no soft mess on the floor before switching on the machine, which will otherwise spread it systematically over the entire floor area.
