The ONEPWR Blade 4 shows how far budget cordless models have come. It handles day-to-day cleaning across carpet and hard floors competently, its removable ONEPWR battery clicks out to charge or swap for a spare, and the 0.6L bin is larger than several pricier rivals so you empty less often. Run time is around 45 minutes, and while you miss out on the sensors, sealed HEPA filtration and outright suction of the flagships, the core cleaning is solid and the washable filter keeps running costs down. For a spare-room, first-home or second-vacuum purchase, it is hard to beat on value.
The good & the bad
Pros
- Excellent value with a removable, swappable battery
- Larger 0.6L bin than many premium rivals
- Simple and light enough for quick everyday jobs
Cons
- No dust sensing and filtration is basic rather than sealed HEPA
- Suction and deep-carpet performance trail the premium models
