A strong pick for carpet and pet hair for about $310. Vacuum Wars measured 93% embedded sand and 91% pet hair pickup with zero hair wrap, plus a 5 L bag dock and a three year warranty. It avoided none of the test obstacles and the mop is basic, so it suits tidy homes.

A low cost way to get auto empty and mop washing with long battery life. Vacuum Wars measured strong carpet cleaning and about 1,831 sq ft per charge. Skip it if you have pets or clutter, since it avoided only 8 of 24 objects and struggled with stains and pet hair.
