Most and Least Reliable Vacuum Cleaners

Nonrobotic Vacuums
We also surveyed our members on any problems they have experienced with their vacuums. According to the results, the most common problem was hair tangling in the rollers. Overall, 18 percent of vacuums have had this problem, with upright models (20 percent) being especially prone to entanglements. It was also a major problem for corded stick vacuums (17 percent), cordless stick vacuums (15 percent), and canister vacuums (13 percent).

Other notable problems that could be found in any type of vacuum included clogged dirt receptacles (11 percent), weak or broken suction (7 percent), and the need to clean the filters too often (7 percent). Additionally, 6 percent of upright vacuums had broken belts.

While these problems also plague cordless vacuums, a trio of battery issues predominated in this particular category: The battery life got worse over time (17 percent), batteries died completely (10 percent), and battery life was never good to begin with (7 percent). 

Dyson, Hoover, and Dirt Devil are three cordless stick vac brands whose battery issues were higher than average compared with other brands in our ratings. Whereas with Miele, Samsung, and LG, the battery issues seemed less prevalent.

Robotic Vacuums
Like their nonrobotic kin, the biggest problem for robotic vacuums is hair getting tangled in the rollers. Nearly one out of three robotics (32 percent) has had this problem. Three other problems, each affecting 12 percent of robotics, are clogs in the hoses or receptacles, deteriorating battery life, and excessively dirty filters.

When it comes to internet-related problems—WiFi connection problems and problems with the app or online functions—each occurred with 9 percent of robotic vacuums.
