Cordless vacuums: the downsides, first

TechRadar found the AI adjustments hit and miss: it ignored a bath mat and room edges, and TechRadar says it doesn't justify its $1,099.99 list price. Samsung.com reviewers rate its AI functionality 1.3 out of 5. Good Housekeeping calls it very expensive.

TechRadar says hair quickly wrapped the main floorhead and the Pet Tool+, and the vacuum was hard to change direction on and get moving on carpet. The motor unit is on the heavier side.

Samsung.com's review summary says some owners report brush-roll failures and malfunctions within the first year, and several criticize the lack of accessory storage and having to clean the microfilter after every use. TechRadar notes you can't turn off auto-empty and must buy dust bags.

The lowest-rated Walmart reviews are dominated by battery complaints: one owner says it ran about 20 minutes, another says it lasts no more than 15 minutes on low, and others say it can't finish a 3-bedroom house. Walmart's AI summary says the battery lasts about 60 minutes in normal modes but only minutes on max. Wirecutter measured more than 40 minutes in medium mode.

Wirecutter says the 45-inch handle can't be adjusted, shorter users may find it awkward, and some testers' thumbs and wrists felt strained after long sessions.

Amazon's review summary says cleaning feedback is mixed, with some owners finding it terrible on carpet and customers disagreeing on quality. Several low-star Walmart owners say suction is poor. Wirecutter notes it comes with only two attachments and has no display or battery countdown.

A low-star Walmart owner says it runs 30 minutes at most in eco/auto and about 15 on max. Amazon's summary says some owners report the battery dying in ten minutes. Good Housekeeping got just over 50 minutes in Eco and wished it included a second battery.

Wirecutter says its bin is 30% smaller than the V10 Konical's and it lacks the newer anti-tangle brush head. Vacuum Wars lists a 440 ml bin.

Low-star Walmart owners describe problems within the first few months, a sticky wand-to-brush connection, and units that arrived looking used or damaged. Amazon's summary says reliability is mixed, including a motor that failed after three years.

Amazon's review summary calls durability concerning, with multiple owners saying it stopped working within a year or broke within three months. Low-star Walmart owners say it stopped sucking up anything after about six weeks, shuts off after 10 seconds, or stopped after a few uses.

Levoit's official runtime with the floorhead is 30 minutes on low and 12 minutes on max; Vacuum Wars saw about 20-25 minutes on max in real use. Amazon's summary says some owners report the battery stops charging.

Vacuum Wars found its bin (580 ml) smaller than average, some suction and airflow numbers below average, an awkward center of gravity in handheld mode, and no battery indicator. Several Walmart owners report poor suction, especially at edges. Good Housekeeping says one tester struggled to get dog hair off sofas with the brush tool.

Wirecutter says it ramps up power too much on medium- and high-pile carpet and seizes, so testers had to turn the power down manually. Walmart's review summary says it struggles on thick or high-pile carpets, and a 1-star owner says it won't roll over rugs.

Tineco claims up to 60 minutes, but Wirecutter got about 30 minutes in auto mode and close to 40 on low. Replacement batteries must be requested by email or phone. A 1-star Walmart owner says it holds a charge for only about 21 minutes, and another says it wouldn't charge out of the box.

Wirecutter says emptying can cause more dust plume than its other picks, and the bin is tricky to reattach. Low-star Walmart owners say it spits debris back out, doesn't pick up dog hair, stopped working after a month, and that the base wouldn't lock in.

Wirecutter says it feels heavy and can tire hands and wrists because the battery sits under the handle. Vacuum Wars measured 1,900 g and notes awkward handheld balance and above-average length. A Walmart owner says it is very heavy, and Amazon owners are split on weight.

Wirecutter says its bin of just over 13 ounces is the smallest of its picks and fills fast with pet hair. The self-standing mechanism limits pivoting, so it misses edges and corners. Vacuum Wars also calls the 400 ml bin small.

Vacuum Wars measured 84 dB (against a 77 dB average) and about 13 minutes on max power. Low-star Walmart owners report 10-20 minutes of battery life, and Amazon battery feedback is mixed.

Wirecutter says it weighs 8 pounds, 2 more than the Dyson V10 Konical, is less maneuverable and can feel heavy on longer sessions. Tom's Guide calls the Clean & Empty version top-heavy. Amazon's summary says several owners find it doesn't glide easily, and a low-star Walmart review calls it too heavy and awkward to handle.

At full power Wirecutter measured 85 dB, the loudest vacuum it tested, and says the noise is annoying. Vacuum Wars lists the Clean & Empty version at 82 dB, and Tom's Guide says auto-emptying is loud.

Amazon's summary says some owners find it doesn't pick up debris well, and others say the battery doesn't last and suction is weak. Low-star Walmart owners say it lost suction after three months and clogs easily. Wirecutter adds that longer hair can tangle in its dual rolls, and Tom's Guide says the sensors need extra cleaning.

Amazon's review summary says durability gets negative feedback, with multiple customers saying it broke within two months. Low-star Walmart reviews call the quality very poor and say it 'just didn't work' from the start.

Amazon's summary says suction, cleaning and pet-hair pickup get mixed feedback: some owners praise the suction, while others say it doesn't pick up debris effectively. A 1-star Walmart owner says it doesn't pick up dirt at all, and another says it had no suction after 5 minutes.

Amazon owners are split between a long-lasting charge and short battery life. A Walmart owner says it barely lasts 15 minutes, and Walmart's summary says runtime can drop to about 20 minutes. Vacuum Wars notes Shark's 40-minute claim is measured on the hand vac in standard mode with no accessories.
