I've got dyson, brilliant for cat and dog hairs the pet one upright with rolla ball good but heavy, there is a light one too still upright still rolla ball bit a bit slimmer and only weighs 5.4 k also new slim one advertised on tv is good and sits ona rechargeable unit and is great for hard floors and cobwebs, it's meant to only lasts for 20 use before its meant to lose its charge but I've had mine over a year now and it's not run out yet! Has separate tools for stairs etc it's really good!
