My Dyson vacuum is on its last legs so looking to replace it soon. We've just moved to a house with light tiled flooring and wooden floors downstairs and carpet upstairs. Light tiled flooring is a nightmare as it shows everything and I could do with hoovering everyday. Have a 3 year old and a 1 year old so needs to be quick and simple. My question is...is the cordless as effective? What's the battery like? Or should I get a normal shark vacuum?
