If you've never experienced the pleasure of a cordless vacuum cleaner, change that as soon as possible. The freedom to bring your vacuum anywhere — without tangled cords trailing behind you — can allow you to get into those dark corners you may have otherwise deemed impossible to clean. 

For a powerful (and inexpensive) option, consider the Inse N5S Cordless Vacuum Cleaner, which is a whopping 78 percent off at Amazon right now. The vacuum cleaner has a 145-watt motor that gives it strong suction power, so it easily picks up pet hair, cat litter, dirt, and debris on both hardwood floors and carpets. It also has an upgraded filtration system that captures particles as small as 0.2 microns, making it easier to breathe indoors.

It comes with several accessories, including a long crevice tool, two-in-one brush tool, retractable metal tube, and motorized brush head, letting you vacuum upholstery, carpeted stairs, and even the interior of a car. 

The vacuum can run for up to 45 minutes before it needs to be charged and has a dust cup that can hold up to 1.2 liters of dirt at a time.
