When we test, we don’t just look at suction power. If you want smart features, look elsewhere in this list, but for pure suction power in a cordless form factor, the Halo Capsule X is an excellent choice. It aced all of our suction tests, and is our pick for the best vacuum for carpet, but it’s equally impressive on hard floors. We have one foam cleaner on our list, the Sprayway Glass Cleaner, our best for shower doors pick.

We enjoyed how it minimized the hassle of cleaning, and would be a good pick for allergy-sufferers too, as it means less manual emptying and less chance to dust to escape back into the air.

In our survey, the Method Glass Cleaner received high praise for smelling good. They have relatively low iodine values and consist of glycerides containing high percentages of such saturated acids as lauric, myristic, and palmitic. Our picks for top glass cleaners took all of this into account, so you can have shiny, streak-free, pleasant-smelling surfaces with no residue left behind.
