How often will the dust bin need emptying?

The robot holds 570 mL of debris in its onboard bin, which is generous for a robot vacuum. Since there is no automatic dust emptying, you empty it by hand, roughly every few cleanings depending on how much your home sheds.

Will it fit under my furniture?

The robot stands 3.8 inches tall, so it slides under sofas and cabinets with at least that much clearance. Its charging dock is compact at 5.1 inches wide and 3.7 inches tall, needing very little floor space.

Can it climb thresholds between rooms?

It clears obstacles up to 20 mm high, so it handles most standard door sills and low transitions between rooms. Taller thresholds above that may stop it.

Can I control how wet the mop is?

Yes, the mopping system offers 3 moisture levels, letting you choose a lighter pass on sealed wood or a wetter one on tile. Water comes from the 235 mL onboard tank.

Does it support scheduling and app control?

It connects to the app for scheduling and mapping, and it works with Amazon Alexa, Google Assistant, and Apple for voice commands. You can also set no-go zones and manage multi-level maps for up to 3 floors.

Is it good for large homes on a single charge?

The 5,200 mAh battery runs up to 285 minutes and covers around 2,411 sq ft per run, enough for most homes in one pass. It also supports off-peak charging.

The trade-offs

Cons

Stationary mop pad just drags moisture, offering the weakest scrubbing of any mop type.
6,000 Pa suction struggles to pull embedded dirt from thicker carpet.
No automatic dust emptying, so you empty the onboard bin by hand.
Lacks smart obstacle avoidance, so it can bump into cords and small objects.
Mop pad stays wet on carpet since it cannot lift or detach.

How the numbers stack up

Performance vs the category

Suction comes in at 6,000 Pa, below the typical robot (category median 15,000 Pa).
At 285 min, runtime is among the longest we track, ahead of about 91% of robots (median 200 min).
Single-run coverage of 2,411 sq ft is about average for the robots we track (category median 2,150 sq ft).
Threshold clearance of 20 mm is about average for the robots we track (category median 20 mm).

Who it's for

People with mostly hard floors who want dependable, mapped cleaning across a couple of levels without spending much. A solid pick for hands-on owners comfortable with routine emptying and refilling.

Who should skip it

Carpet-heavy homes and anyone wanting a fully hands-off dock that empties dust and washes mop pads. Those needing deep scrubbing of stuck-on messes should look elsewhere.

The bottom line

Our take

The D9 Max Gen 2 brings genuine LiDAR mapping and multi-floor support to a budget-friendly package, and it handles hard floors and light mopping well. Suction and the basic stationary mop pad limit deep cleaning, and the dock leaves emptying and refilling to you.
