Best cordless vacuums for hassle-free cleaning

If you or a family member suffer from allergies, you know the importance of keeping the house dust- and dander-free. And you also know that a simple Dustbuster just don’t cut it. Consider the Black+Decker Powerseries Pro Cordless Anti-Allergen Vacuum.
With a high-performance filter, this 2-in-1 vacuum is optimized to capture 99.99 percent of allergens, such as pet dander and dust particles. The filter is washable and reusable and you can purchase replacement filters to improve vacuum performance (its FILTERSENSE technology notifies you when it’s time to replace the filter). 
But there’s more to this vac than an effective filter. Its 60 minutes of run time (with canister in low speed) means you can tackle more messes in the house, and its swivel steering design makes it easy to maneuver in tight spaces. It’s equipped with other smart features, including AUTOSENSE technology, which automatically adjusts suction from bare floor to thick carpet to optimize run time, and an LED light which illuminates cleaning surfaces and ensures you bust the dust more thoroughly. 
Amazon reviewer writes:

“[This] works great at grabbing up dust and pet fur from our hardwood floors! As an allergy person, this is very important to me. Not as heavy and loud as our lightweight electrical vacuum and is easy to clean. I’ve had this product for awhile and it still works really well—I use it everyday!”

“Black+Decker’s Powerseries Pro Cordless Lithium 2in1 Stick Vacuum is a great little machine to have around the house. Being cordless, yet able to clean up messes with a decent amount of power really makes it handy… You can adjust the power level (which also shortens battery life), which is nice. Sometimes you are cleaning up a small mess that does not require much power. But other times, you need the extra suction, for instance pet hair. I find myself using it more on the higher power settings and more for spot cleaning than full cleaning sessions. It’s also great for stairs, although, again, I use it on the highest power setting. It’s nice and light and easy to operate… There are plenty of attachments to cover just about any job that you have. The container is a good size and will hold a decent amount before having to empty. I often find myself using the removable canister. I just love the ease of use without cords. I really like having this little guy around the house!”
