I think it say's somewhere on the website that they can be lifted one handed, take that as a bit tongue in cheek, they weigh around 38 KG, which is lighter than some. Not sure if you will get in the back of estate car though, and that could be said for most machines. That been said the Scorpion is a great machine and at around £20 per week is very affordable, just don't forget all the extra's you will need like wand, hoses, spray pump's, brushes, chemicals / solutions, vacuum cleaner, agitator ie sebo duo, dryer, and other bits and pieces!!
