Your choice of sweeper depends mostly on your budget and what special features you need. Do you have pets that shed a lot of hair, family members with allergies, do you prefer cord or cordless and do you need any special attachments? Cordless models have a rechargeable battery, so good to know how long you can sweep on a single charge and how expensive the battery is to replace when it no longer holds a charge. Sweepers sometimes have replaceable filters that can be pricey, so make sure to look into that when buying. They either have dust collection bags that you dispose of when full or some type of holder you empty periodically. There are some now sold that seem REALLY expensive and honestly they all have a motor to create suction and spin brushes. I am somewhat suspicious of those slick TV ads which imply what an amazing job their pricey product does compared to everyone else. Those robotic vacuums seems really small and have never used one, so hard to say if they are more of a gadget then a practical sweeper for home use.
