How useful can a cordless vaccuum cleaner really be? The answer is, more than you might realise. The Vax Life is very small, very light, and very easy to give the house a quick once over with. It's surprising how much the cable slows you down on a normal vaccuum, and I was able to complete a full sweep of the house in about half the time it usually takes.
However there are of course, some limitations. Chiefly the lack of suction power. Compared to, for example, a Dyson, the Vax struggles to pick up anything more than hairs and dust, and when it comes to carpet it doesn't really pick up much of anything at all. On wood floors it works a lot better, but even then is limited to tiny objects.
Also the design of the Vax locks the brushes in place, and they cannot be removed (without taking the whole thing apart by the looks of it) which makes cleaning it up time consuming and fiddly. If you have people with long hair in the house, this will quickly get annoying.
A useful but flawed product then, and one I would recommend primarily for people with lots of wood flooring, short hair, and a desire to clean often.
