Wyze Cordless Vacuum S vs Black+Decker dustbuster FLEX Cordless Stick Vacuum with Floor Head
Quick take: The Wyze Cordless Vacuum S costs $43 less; the Wyze Cordless Vacuum S runs longer per charge (40 vs 20 min).
Which one to buy
At $130 each, the Wyze Cordless Vacuum S is the floor vacuum and the Black+Decker dustbuster FLEX is a handheld that reaches the floor. The Wyze has a brushless motor rated at 20,000 Pa in Turbo, a 0.7 L bin and a 40-minute Eco rating; owners say Eco gives a real 40 minutes for daily passes and Turbo does the work on rugs in short bursts. Its battery is removable and Wyze sells spares, so a second pack takes you to about 100 minutes, and owners report units running two years without problems.
The FLEX's strengths are versatility and staying power. The same 3.2 lb body works as a handheld, with a 4-foot hose, or on its pivoting floor head, and owners say its pet brush leaves clean lines on carpeted stairs and pulls hair out of car seats. Some report units still running after 7 years. But its 502 ml bin and 20-minute rating limit it to quick jobs, owners say floor mode still asks you to bend or angle the handheld body, and the battery is sealed in, so a worn cell means a new vacuum. Its thin filter needs frequent washing or suction fades and dust blows back into the room. It does carry a 2-year warranty to the Wyze's 1 year, which Wyze owners call the shortest in its class.
Wyze owners are clear about their machine's limits too: it's scoped to hard floors and low-to-medium pile, it has no anti-tangle comb so long hair winds the roller, and some report brushroll wear under heavy use. Even so, for an apartment that needs one vacuum, the Wyze is the better buy. The FLEX makes sense as a second machine for stairs, the car and upholstery.
Wyze Cordless Vacuum S
For an apartment or hard-floor home that needs one daily stick, with a 0.7 L bin, up to 40 minutes and spare batteries you can buy.
Black+Decker dustbuster FLEX Cordless Stick Vacuum with Floor Head

Wyze Cordless Vacuum S vs Black+Decker dustbuster FLEX Cordless Stick Vacuum with Floor Head: common questions
Can the Black+Decker dustbuster FLEX replace the Wyze Cordless Vacuum S as a main vacuum?▾
Not for most homes. The FLEX is rated for 20 minutes with a 502 ml bin, and its owners say floor mode still means bending over a handheld body. The Wyze is rated for 40 minutes in Eco with a 0.7 L bin that owners say finishes a whole apartment on one empty.
Which battery lasts longer in the life of the vacuum, the Wyze Cordless Vacuum S or the Black+Decker FLEX?▾
The Wyze's battery is removable and sold as a spare, so a worn pack never retires the vacuum. The FLEX's battery is sealed into the handle, so when it fades the practical fix is a new unit, though some owners report going 7 years before that happens.
Which has the better warranty, the Wyze Cordless Vacuum S or the Black+Decker FLEX?▾
The Black+Decker, at 2 years against Wyze's 1. Wyze owners call that the shortest in its class, though the replaceable battery takes away the most common reason a budget stick dies early.
