Its NeverTouch Pro base washes the mop pad with 185 F water and dries it with heat, which owners say is the difference between a pad that cleans and one that smears, and the robot covers a whole home on one charge when vacuuming only, with a 379 ml onboard bin against 325 ml for the Roborock Qrevo S5V. The Roborock Qrevo S5V answers with the lower price, a published 12,000 Pa suction rating where the Shark does not document one, and a self-emptying dock that washes and warm-air dries the mop. Choose the Shark PowerDetect ThermaCharged RV2920XE for heated mop care and warranty, and the Roborock Qrevo S5V for price and a documented suction figure.

What the differences mean

Heated mop washing

The Shark PowerDetect ThermaCharged RV2920XE washes the mop pad with 185 F water and dries it with heat at the base. The Roborock Qrevo S5V washes and warm-air dries its mops but does not publish the water temperature, so the heated cycle belongs to the Shark.

Warranty

The Shark PowerDetect ThermaCharged RV2920XE carries a two-year warranty against one year for the Roborock Qrevo S5V. For a robot with a dock and a motor, the extra year of cover is a concrete difference.

Onboard bin

The Shark PowerDetect ThermaCharged RV2920XE carries a 379 ml onboard bin against 325 ml for the Roborock Qrevo S5V. Both empty into their docks, so the larger bin helps most on an interrupted run.

Single-charge coverage

Owners report the Shark PowerDetect ThermaCharged RV2920XE covers a whole home on one charge when vacuuming only, needing a mid-run top-up if it vacuums and mops together. The Roborock Qrevo S5V is rated for 180 minutes and also recharges and resumes.

Published suction

The Roborock Qrevo S5V is rated at 12,000 Pa, while the Shark PowerDetect ThermaCharged RV2920XE does not publish a suction figure. With no number on the Shark side, buyers who want a documented rating have only one to compare.

Water reservoir

Owners report the Shark PowerDetect ThermaCharged RV2920XE water reservoir lasting around eight mopping runs. The Roborock Qrevo S5V publishes a dock tank but leaves the volumetric capacity undocumented, so the two are hard to line up on refill frequency.

Which one to buy if

What owners say

Owners of both robots describe a dock that removes most of the weekly work, and both groups include pet households who say it keeps up with hair. Shark PowerDetect ThermaCharged RV2920XE owners single out the heated 185 F mop washing, the whole-home coverage on a single vacuuming charge, and mopping on wood and tile they call outstanding, with parents running it nightly around a crawling baby. Roborock Qrevo S5V owners focus on pet-hair pickup, quiet running and the improvement over older robots. Their complaints part sharply: Shark owners report frequently failing to leave or return to the dock, a mop self-clean cycle that falsely reports an obstruction, water dispensing stopping on some units within months and hard-to-follow instructions. Roborock Qrevo S5V owners mostly fault the app's map and room tools.

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.

Frequently Asked Questions

Which is better overall: Roborock Qrevo S5V or Shark PowerDetect ThermaCharged RV2920XE?

The Shark PowerDetect ThermaCharged RV2920XE wins on heated mop washing, warranty and single-charge coverage. The Roborock Qrevo S5V is the better buy on price, has a published suction rating, and its owners report fewer dock-related faults.

What is the biggest difference between the Roborock Qrevo S5V and the Shark PowerDetect ThermaCharged RV2920XE?

The Shark PowerDetect ThermaCharged RV2920XE washes its mop in 185 F water and dries it with heat, and carries a two-year warranty, where the Roborock Qrevo S5V does not publish a wash temperature and comes with one year.

Does the Shark PowerDetect ThermaCharged RV2920XE publish a suction rating?

No, it does not document one. The Roborock Qrevo S5V is rated at 12,000 Pa, so if a published suction figure matters to you, that is the one of the pair to compare against.

What faults do owners report on the Shark PowerDetect ThermaCharged RV2920XE?

Docking is the most common: owners report it frequently failing to leave or return to the base, needing to be placed back by hand. Others report the mop self-cleaning cycle falsely signalling an obstruction, and some units stop dispensing water for the mop within a few months.

Do both robots empty and dry their mops?

Yes. Both the Shark PowerDetect ThermaCharged RV2920XE and the Roborock Qrevo S5V self-empty, wash the mop and dry it. The Shark also heats its wash water to 185 F, and neither dispenses detergent automatically.

Who should buy the Roborock Qrevo S5V?

Buyers who want a lower price, hands-off emptying and mop cleaning, and a documented suction rating, and who do not need heated mop washing or a two-year warranty.

Who should buy the Shark PowerDetect ThermaCharged RV2920XE?

Homes that prioritise heated mop care and a longer warranty, want whole-home coverage on a vacuuming charge, and can live with the docking and self-clean faults owners report.
