The dearest model here, and that high price eats into the points. Although this marginally trumped the Shark in our carpet and hard floor tests, it lacks Shark’s ingenuity. With the extra battery and charging pod, the Bosch gives almost 20 minutes’ use at top power. But so does the Shark. The crevice tool is great, but the unit’s floor head is less sophisticated than the Shark’s.
