UV Reveal
Pick it for the newer obstacle/navigation platform, battery gains and UV stain detection.
The better robot and the better purchase are not always the same thing. UV Reveal is Shark's stronger current platform; ThermaCharged can win on value when UK discounts are large.

Pick it for the newer obstacle/navigation platform, battery gains and UV stain detection.

Pick it when the price saving matters more than UV stain detection and the latest obstacle-avoidance gains.
| Difference | UV Reveal | ThermaCharged |
|---|---|---|
| Current checked UK price | £639.99 | £469.99 |
| Vacuuming | Strong; 88% carpet deep-clean result in Vacuum Wars test | Strong hard-floor and carpet result in Tom's Guide hands-on review |
| Mopping | Excellent dried-stain removal; UV-triggered extra passes | Very effective everyday mopping; hot wash/dry dock |
| Water use | Major caveat: unusually wet in Vacuum Wars testing | Wet-floor caveat also noted in hands-on testing, but the UV model's extreme water result is the bigger concern |
| Obstacle avoidance | 20/24 objects in Vacuum Wars — best Shark result they had recorded | Older platform; capable navigation but occasional getting-lost behaviour reported |
| Battery | 180 min official; independent efficiency improved sharply | 180 min official |
| Multi-floor maps | No | Do not assume premium multi-floor map depth; verify app needs before buying |
| Best for | Shoppers who want Shark's strongest robot and value stain/obstacle improvements | Shoppers who want the premium Shark dock/cleaning package at the better price |
If the two are close in price, RightRobot would take UV Reveal because the independent obstacle, navigation and battery gains are meaningful. If ThermaCharged is hundreds of pounds cheaper, the decision changes: it still offers strong vacuuming/mopping and the premium hot-wash/hot-dry dock.
Neither answer should override your actual home. Carpet area, hard-floor mopping, clutter, thresholds, pets and budget can still push Home Fit toward a different Shark — or a different brand.
