It maps with LiDAR, sets no-go zones in an app and self-empties, washes and dries its mop at the dock, all things the gyroscope-driven Tikom cannot do. The Tikom G8000 Max answers with a slim 78 mm body, a 450ml onboard bin, a quiet 45 dB rating and a much lower asking price. Pick the Shark PowerDetect ThermaCharged RV2920XE for scheduled hands-off cleaning across rooms, and the Tikom G8000 Max if you want an affordable daily sweeper for a tidy, mostly hard-floor home.

What the differences mean

Navigation

The Shark PowerDetect ThermaCharged RV2920XE navigates with LiDAR, builds a saved map and offers app no-go zones. The Tikom G8000 Max uses a gyroscope, cleans in rows with no stored floor plan, and blocks areas with the supplied magnetic strip instead.

Docking

The Shark PowerDetect ThermaCharged RV2920XE self-empties, and washes and dries its mop pad with heat. The Tikom G8000 Max sits on a plain charging station, so the 450ml bin is emptied by hand and the mopping cloth is rinsed by hand.

Battery life

The Shark PowerDetect ThermaCharged RV2920XE is rated for 180 minutes and the Tikom G8000 Max for 150, and the Shark recharges in about four hours against six and a half on the Tikom.

Warranty

Shark backs the PowerDetect ThermaCharged RV2920XE for two years, while Tikom covers the G8000 Max for one, so the Shark carries the longer protection of the two.

Onboard bin

The Tikom G8000 Max holds a 450ml onboard bin, larger than the 379ml of the Shark PowerDetect ThermaCharged RV2920XE. Since the Tikom does not self-empty, that bigger bin is what lets it go a full run between hand empties.

What owners say

Owners of both robots are candid about what each is for. Shark PowerDetect ThermaCharged RV2920XE owners, parents and pet households among them, praise heated mop-pad washing, quiet operation, accurate mapping and whole-home coverage on one charge, and their recurring faults are docking, a mop self-clean that reports false obstructions and water dispensing that stops on some units. Tikom G8000 Max owners are equally clear: they are surprised by how much the 450ml bin holds and how quietly it runs, and they accept that a gyroscope steers it in rows with no saved map, that cables stop it and that the magnetic strip in the box is too short for a whole home.
