Hoover HG2 Hydro ProTurboSlim Robot Vacuum Cleaner Review – A Smart Cleaning Companion for Pet Owners and Allergy Sufferers

Third-party reviews

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

What customers like about Hoover HG2 Hydro

  • Ultra-slim design fits easily underneath low-profile furniture like beds and sofas
  • Strong 5000 Pa suction power effectively picks up hidden dust, crumbs, and pet hair
  • Convenient 2-in-1 functionality that vacuums and mops simultaneously in a single pass
  • Long battery runtime of up to 160 minutes allows it to clean large spaces on a single charge
  • User-friendly HG Robots app makes it easy to control suction power, mopping moisture, and schedules
  • Self-emptying station (on Pro/Turbo models) provides up to 60 days of hands-free maintenance
  • Quiet operation while vacuuming

What customers don't like about Hoover HG2 Hydro

  • Struggles with obstacle avoidance and can get tangled on small items like cables, strings, or toys
  • May miss certain spots or struggle to adapt if there are frequent changes in the home environment
  • Lacks an automatic alert notification to inform the user when the on-board dustbin is completely full
  • The 3-liter self-emptying dock takes up extra physical space, making storage difficult in smaller homes
  • Initial app setup can occasionally be tricky or unintuitive for some users

Verdict

The Hoover HG2 Hydro is a low-profile, 2-in-1 robot vacuum and mop featuring a notable 5,000 Pa suction power and a runtime of up to 160 minutes on a single 5-hour charge. Its primary advantages include an ultra-slim 8.3 cm height that easily slips under low furniture, simultaneous vacuuming and sweeping with adjustable water levels via the HG Robots App, advanced Point-Laser mapping navigation, and a 60-day hands-free self-emptying base station with a 3-litre dust capacity. On the downside, the device is prone to leaving light wheel track marks on damp floors, exhibits mixed accuracy with its obstacle recognition and no-go zone compliance, and lacks the deeply intense scrubbing motion found on premium dedicated mopping competitors.
