Ecovacs DEEBOT T30S Combo vs Shark PowerDetect ThermaCharged RV2920XE

Full Robot Vacuums comparison in 2026

Updated October 2026
Data from Amazon and official Ecovacs and Shark sites.
2026 verdict
When one box has to cover the whole home, the Shark PowerDetect ThermaCharged RV2920XE is the robot vacuum to buy of these two.
It is the better reviewed of the pair, carries a two-year warranty against one, holds a larger onboard bin and undercuts the Ecovacs DEEBOT T30S Combo on price. Heated 185F mop washing and whole-home coverage on a single vacuuming charge are its headline draws. The Ecovacs DEEBOT T30S Combo counters with a cordless handheld that shares its base, 200 minutes of runtime and a 3 L dock bag, so it is the pick for stairs, sofas and car interiors that no robot reaches. Choose the Shark PowerDetect ThermaCharged RV2920XE for floors alone and the Ecovacs DEEBOT T30S Combo when you need above-floor cleaning too.

What the differences mean

Above-floor cleaning

The Ecovacs DEEBOT T30S Combo bundles a cordless handheld that docks into and empties from the same base, so stairs, upholstery, car seats and vents are covered by the same purchase. The Shark PowerDetect ThermaCharged RV2920XE is a floor-only robot, so anything above floor level is a separate appliance.

Warranty

Shark covers the PowerDetect ThermaCharged RV2920XE for two years against one for the Ecovacs DEEBOT T30S Combo. For a machine whose owners report docking faults, the second year of cover is worth more than it looks.

Runtime

The Ecovacs DEEBOT T30S Combo is rated at 200 minutes against 180 for the Shark PowerDetect ThermaCharged RV2920XE, a modest edge. In practice the Shark's owners note a combined vacuum and mop run still needs a recharge partway, so the gap narrows further with mopping in the mix.

Mopping

Both lift the mop on carpet, and both wash and dry their pads at the station. The Shark PowerDetect ThermaCharged RV2920XE does it with 185F heated water, which its owners credit for cleaner pads, while the Ecovacs DEEBOT T30S Combo uses a roller-style self-cleaning mop on a 4 L tank.

Dock bin

The Shark PowerDetect ThermaCharged RV2920XE carries a larger 379ml onboard bin than the Ecovacs DEEBOT T30S Combo's 275ml, though the Combo's dock bag is slightly bigger at 3 L. Neither is a reason on its own, but both self-empty, so the difference is only how often you look at them.

Which one to buy if

What owners say

Owners of the Shark PowerDetect ThermaCharged RV2920XE are notably positive about its core promise: the base washes the mop pad with 185F water and dries it, which they describe as the difference between a pad that cleans and one that pushes dirt around, and they report covering a whole home on one charge when vacuuming only and about eight mopping runs per reservoir fill. Families with pets and young children are the most enthusiastic group, repeatedly calling it their best purchase. Their complaints are specific and worth weighing: the robot frequently fails to leave or return to the dock, the mop self-cleaning cycle falsely reports obstructions, and water dispensing stops entirely on some units within months.
