Vacuum cleaners

Trying to buy a new vacuum cleaner can be a pretty confusing experience. Do you go bagged or bagless? Corded or cordless? Is it worth paying extra for something with anti hair wrap tech? Or forking out for a robot to do it all for you? That's what listener Sally is tempted by - she wants to know if a robot will clean as well as a regular handheld version. Listener Rachel wants advice on which features are worth the extra cash. To help them navigate this complicated market, Greg consults Grace Forell, a consumer expert from Which? and host of its Get Answers podcast - and finds out all about dust with professor Hasan Arshad, who leads allergy research at the University of Southampton.
