How much water does it remove per day?

It is rated at 32 pints, or 0.6 gallons, per 24 hours at standard test conditions. Real-world output drops in cooler rooms, so expect less in a cold basement.

Do I have to empty the tank every day?

At full output the 0.6 gal tank fills in about a day. In a very damp room, plan on emptying it daily or connecting a drain hose if one fits.

What size room is it good for?

It is rated for up to 2,000 sq ft, but that assumes open, moderately damp space. For a wet basement or a large open floor, a 50-pint unit will do the job faster.

Is it loud enough to disturb sleep?

It uses a compressor, so it produces a steady hum plus fan noise. Most people keep it out of the bedroom at night or run it during the day.

Does it have a drain hose option?

The listed features cover only the display and dehumidifying function, so confirm continuous drainage with the seller before relying on it for unattended use.

Is it worth it over a larger dehumidifier?

For a bedroom, bathroom or closet, yes: it is smaller and easier to move. For a whole basement, a higher-capacity unit with a bigger tank or a drain hose is the better fit.
