Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What we like about Shark CH951

  • Excellent suction power for quick cleanups, especially on low-pile carpets and hard floors
  • Effective at picking up both pet and human hair without easily tangling or clogging
  • Cordless and highly portable, making it incredibly convenient for cleaning cars, upholstery, and small spaces
  • Generous dust cup capacity for a handheld device, requiring less frequent emptying
  • User-friendly design with a simple, one-touch button for hygienic debris emptying

What we don't like about Shark CH951

  • Short battery life, typically yielding around 10 to 14 minutes of continuous runtime per charge
  • Can take a significant amount of time to fully recharge when the battery dies
  • Some users report that the turbo brush attachment struggles with deeply embedded pet hair
  • Can be perceived as slightly bulky and lacking that 'touch more power' compared to premium alternatives

Verdict

The Shark UltraCyclone Pet Pro+ (CH951) is a lightweight 2.8-pound cordless handheld vacuum equipped with two cyclical air streams, a 10.8V lithium-ion battery, an 80-watt motor, and a 0.45-quart dust cup. Key characteristics and advantages include its motorized self-cleaning Pet Power Brush that effectively eliminates hair wrap, a crevice tool, an upholstery tool, and a one-touch button for hygienic, hands-free debris emptying. However, the device is constrained by a short 10-to-15-minute runtime per charge, a prolonged 4-to-6-hour battery recharging cycle, and the absence of a wall-mountable charging dock.
