Shark HydroVac MessMaster vs Kärcher FC 7 Cordless Hard Floor Cleaner

The Kärcher FC 7 is the stronger hard-floor cleaner: about 45 minutes of runtime, a 300 mm roller, 59 dB operation and roughly 2-minute drying. The Shark HydroVac MessMaster is the more versatile pick because it vacuums dry debris and cleans area rugs as well as sealed floors, with a HEPA filter and self-cleaning. Owners rate the Shark around 3.8 out of 5, so expect solid convenience but some complaints; Kärcher's hard-floor hardware is the more proven design for pure mopping.

• Choose the Shark HydroVac MessMaster if you want one cordless machine that picks up dry messes, washes sealed floors and refreshes area rugs, and you have pets.
• Choose the Kärcher FC 7 if your floors are mostly hard surfaces and you want longer runtime, a wider roller and faster drying.
