Which Roborock Qrevo model should I buy — the Ultra or the Plus?

Regarding the Roborock: Get the Qrevo Plus ($700-800) if you want premium features at a reasonable price — it’s the smart choice for most first-time owners. Get the Qrevo Ultra ($1,200-1,400) only if you want to press one button and forget cleaning exists, since it washes its own mop pads and handles everything itself. The extra $400-600 buys you amnesia about your floors.
