Reviews last updated: July 2026 · How we calculate this

What customers like about BISSELL 2931N

  • Excellent mopping functionality with dual active spinning pads
  • Effective at automatically avoiding carpets and area rugs while in mop mode
  • Operates very quietly compared to many other robot vacuums
  • Performs well at sweeping up loose debris and surface dust on hard floors
  • The dustbin and water tanks are straightforward to remove, swap, and clean
  • Offers a user-friendly companion mobile application for scheduling and controls

What customers don't like about BISSELL 2931N

  • Lacks advanced LiDAR or camera mapping, relying on basic gyroscope navigation
  • Prone to getting stuck in narrow spaces, on furniture legs, or on loose rug tassels
  • Inefficient cleaning patterns that can leave some areas missed while over-cleaning others
  • Mediocre vacuum suction power on thick or heavy pile carpets
  • Battery charging issues and fatal power defects reported by multiple users out of the box
  • No digital no-go zones or virtual boundaries supported in the software

Verdict

The BISSELL SpinWave Robot 2931N is a versatile 2-in-1 wet and dry robotic cleaner utilizing a 14.4V Li-Ion battery that provides up to 130 minutes of run time, recharging fully in 4 hours. Key technical specifications include a 1500 Pa maximum suction power, an 8.5 cm low-profile height, a 0.4-litre dirt tank capacity, and structured gyro-navigation technology operating at a quiet 52 decibels. Main performance pros include its dual-tank flexibility to switch between dry vacuuming and active wet mopping with dual rotating scrub pads, alongside automated carpet avoidance sensors during wet cycles and convenient scheduling via the BISSELL Connect app. However, primary cons include its reliance on basic gyroscopic tracking over advanced LiDAR mapping, which limits complex zone division, and a relatively small dustbin capacity that requires frequent emptying.
