Winner
MOVA E40 Ultra
Buy on Amazon GermanyCheck price
It runs 260 minutes against 180, is covered for three years against two, and states its suction at 19000 Pa, a figure Shark does not publish for its robot. The Shark PowerDetect ThermaCharged RV2920XE is a close rival: its dock washes the mop with heated water and dries it, it has a larger 379 ml onboard bin, and owners praise its mopping on wood and tile. Both robot vacuums self-empty, lift their mops and work with Alexa, Google Home and Home Assistant. Choose the MOVA E40 Ultra for endurance and warranty, and the Shark PowerDetect ThermaCharged RV2920XE if hard-floor mopping is your priority.

What the differences mean

Battery

The MOVA E40 Ultra runs 260 minutes and the Shark PowerDetect ThermaCharged RV2920XE 180. Shark owners say theirs needs a recharge mainly when it vacuums and mops in the same run, so the extra time counts most on combined jobs.

Warranty

Three years for the MOVA E40 Ultra, two for the Shark PowerDetect ThermaCharged RV2920XE. Both are longer than the usual one year.

Suction figures

MOVA rates the MOVA E40 Ultra at 19000 Pa. Shark does not publish a figure for the Shark PowerDetect ThermaCharged RV2920XE, so the two cannot be compared on numbers.

Bin and water

The Shark PowerDetect ThermaCharged RV2920XE has a 379 ml onboard bin. The MOVA E40 Ultra publishes a 4.5 L water tank and a 3.2 L dock bag, where Shark lists neither.

Which one to buy if

What owners say

Owners of both robots say they cover a whole home on one charge and praise accurate mapping and quiet running. MOVA E40 Ultra owners single out how fast it maps a large floor, steady pet hair pickup from multi-dog homes and a station that washes pads, empties the bin and refills during a job, and their complaints are mop pads detaching mid-run, side-brush and motor failures within months and slow support escalation. Shark PowerDetect ThermaCharged RV2920XE owners call its mopping on wood and tile outstanding and like that it tells carpet from hardwood, but report failures to leave or return to the dock, false obstruction alerts from the mop self-cleaning, water dispensing that stops on some units and instructions that are hard to follow.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
