Shark Detect Pro Robot Vacuum vs iRobot Roomba Plus 515 Combo

Buy the Roomba Plus 515 Combo if you want one machine to vacuum and mop, and you have pets or a mix of carpet and hard floors. Its AutoWash dock washes and hot-air dries the mop pads, lifts them 10 mm over rugs, and its LiDAR mapping avoids clutter. The Shark Detect Pro is a vacuum-only robot with a bagless self-empty base, HEPA filtration and a longer claimed runtime, but no mopping. Owners rate the Roomba higher, though from far fewer reviews.

  • Choose the Shark Detect Pro if you only need vacuuming, want HEPA filtration for allergies, and prefer a bagless base.
  • Choose the Roomba Plus 515 Combo if you want vacuuming and mopping in one run, with a dock that washes and dries the mop pads.

What reviewers say

Shark Detect Pro Robot Vacuum

  • 4.5 / 5222 ratings

Rated 4.5 out of 5 from 222 ratings, the Detect Pro draws praise for its self-emptying base and HEPA filtration. Owners of pets and allergies report less dust and less bin handling. Some find it loud at full power and slower to cover a room than wider robots.

What people mention
  • Self-emptyingPraisedOwners like that the base empties the bin so they go weeks without handling dust.
  • FiltrationPraisedThe HEPA filter is cited by allergy and pet owners as a reason they bought it.
  • NoiseCriticisedMax mode at 65 dB is described as loud enough to interrupt conversation.
  • Cleaning widthMixedThe 5.7-inch path covers less ground per pass, so rooms take longer.

iRobot Roomba Plus 515 Combo

  • 4.8 / 549 ratings

Rated 4.8 out of 5 from 49 ratings, the Plus 515 Combo is well received by owners who value the self-washing dock and strong pickup on pet hair. Complaints center on dock upkeep and the small onboard bin.

What people mention
  • Dock upkeepMixedOwners like the hands-free emptying and pad washing but note the dock still needs water refills and bag changes.
  • Pet hairPraisedRubber-and-bristle brushes pull in shedding fur without clogging, owners say.
  • MoppingPraisedDualSpin pads with extra pressure handle dried spills and kitchen splatter, and lift over rugs.
  • BatteryMixed

Questions and answers

Which is better for pet hair?
Both target pet hair. The Roomba adds tangle-resistant rubber brushes and a mop for muddy paw prints. The Shark relies on boosted suction and HEPA filtration to trap allergens.
Which is better for allergies?
The Shark Detect Pro, because it is HEPA certified. The Roomba's filtration is not listed as HEPA.
Do I need the Roomba's mopping?
Only if you have hard floors with dried spills or muddy prints. If you have mostly carpet, the Shark's vacuum-only design is simpler and has no mop pads to maintain.
Which lasts longer per charge?
The Roomba, at up to 295 minutes versus about 120 minutes for the Shark. Real runtime drops on max suction and with mopping.
Is the Roomba worth stepping up to?
Yes if you want mopping, carpet detection and a self-washing dock in one machine. The Shark is the better fit if HEPA filtration and a bagless base matter more.
