A testing lab has evaluated dozens of vacuums and identified top performers. The best vacuums include models from brands such as Shark, Dyson, and Bissell, with prices starting at $65, although the exact number of top-rated vacuums and their specific features are unclear. The testing appears to have covered various types of vacuums, including upright, robot, and canister models, as well as their effectiveness on different surfaces and with pet hair.
