iRobot Roomba 205 vs Shark PowerDetect ThermaCharged RV2920XE

The Shark PowerDetect ThermaCharged RV2920XE takes the overall win, with a longer battery life, a longer warranty, a higher owner rating, and full mopping with auto mop washing, auto mop drying and self-emptying. The iRobot Roomba 205 answers back with a lower price, broader WiFi connectivity and more app integrations, but it does not mop.

The Roomba 205 is vacuum-only, using an internal DustCompactor and a compact charging base instead of a self-emptying tower. The Shark PowerDetect ThermaCharged RV2920XE is a full vacuum-and-mop system with a self-emptying dock that also washes and dries its own mop pad, which is the core reason it wins this matchup.

Yes. It supports 5GHz WiFi in addition to 2.4GHz and connects to IFTTT, neither of which the Shark PowerDetect ThermaCharged RV2920XE offers, and it is the more affordable option of the two. Both models otherwise share the same LiDAR navigation, obstacle and cliff detection, multi-room mapping and no-go zones.

The Shark PowerDetect ThermaCharged RV2920XE ships with a two-year warranty and a 180-minute battery, both longer than the iRobot Roomba 205's one-year warranty and 120-minute battery. This gap is part of why the Shark model wins the overall comparison.

Buyers who only need vacuuming, want a compact charging base instead of a bulky auto-empty dock, and prefer to pay less should choose the iRobot Roomba 205.

Households that want an all-in-one vacuum and mop robot with self-emptying and heated mop pad washing, and that value a longer battery life and warranty, should choose the Shark PowerDetect ThermaCharged RV2920XE.
