The Ultenic U10 enters a saturated market, but the company hopes to set its vacuum apart with its 'infrared dust detection technology', HEPA Filtration System and its 23,000 Pa of suction power. The U10 retails for US$189, but Ultenic is currently selling it for just US$149. The Ultenic U10 is available in the UK and the Eurozone, too.

So a vacuum that takes 3 hours to charge, and operates on high for 15 minutes... that's a trifle funny. Also seems direct from Aliexpress. Also that accessories holder should be on the wall mount, not wiggling around when you are using the vacuum..
I own a $100 BISSELL® ICONpet I bought from lowes. It was on clearance, the run time is about 30 minutes on the highest setting, with a 4 hour charge time. It's OK, I wouldn't pay full price tho.
Wirecutter recommends the $300 Dyson V7 Motorhead (30 min runtime, 3.5 hour charge), with the upgrade pick being a $500 Miele Triflex HX1 (60 min run time, 4 hour charge.. battery is removable/replaceable.)
I plan on trying the Samsung Jet 70 next, when the ICONpet stops working. Comes with a replacable battery with 40 minute run time, and recharges in 1.5 hours. Fastest I've seen..
