<p><strong>Milwaukee</strong></p><p>amazon.com</p><p><strong>$149.99</strong></p><p>Milwaukee really makes everything these days, so we had to try the <strong>Milwaukee</strong> <strong>M18 Cordless Vacuum</strong>. Right off the bat, you're looking at the winner of our battery-life test—the M18 RedLithium XC5.0 beating all of the contenders with a healthy 23-minute, 24-second time.</p><p>The collection chamber is nice and large, and emptying it is simple. The vacuum doesn't produce that much noise, either—but all the excess air blows out from the top, so expect a warm breeze as you use it. </p><p>The crevice attachment is sadly skinny, and it struggled against Cheerios and Cheez-Its, as seen in the photo below. Weighing in at nearly six pounds, it does get the forearms burning after extended use.</p><p>The other knock is you'll need Milwaukee's proprietary M18 battery and charger, sold separately. But if you already have other Milwaukee M18 tools, the battery works with this vacuum like a charm. For a long cleaning session, this is the way to go.</p>
