Miele Triflex HXI: from £479: Miele's first cordless vacuum cleaner is powerful and well designed, a potential Dyson-beater. It's a 3-in-1 vac with a difference: it's truly convertible. Use as a bottom-heavy upright, top-heavy stick cleaner or compact handheld, all with the same power. Battery life is up to 60 minutes and some models boast HEPA filtration. miele.co.uk/triflex
