## Verdict

A simple, low cost LiDAR robot that vacuums well and empties itself into a bag that lasts months. Android Authority and PCWorld both liked its navigation and value. Skip it if you have loose rugs, cables or toys on the floor, or want real mopping, since it has no camera and only a basic drag pad.

## Pros

- Strong claimed suction for the price
- Bag holds up to 120 days per Dreame
- Reliable LiDAR navigation in two reviews
- Low 3.7 in height fits under furniture
- 3 year warranty

## Cons

- No camera, so it pushes small rugs and objects
- Basic drag mop with no lift or washing
- Louder than average per both reviewers
- Ongoing cost of dust bags

## Questions buyers ask

### How often do I change the dust bag?

Dreame says the 4 L bag holds up to 120 days of debris, based on its own lab calculation. Heavy use fills it sooner.

### Does the dock wash the mop?

No. The dock only empties the bin and charges. The mop is a flat pad you wash yourself, and it does not lift over rugs (PCWorld).

### Will it avoid cables and socks?

Not reliably. It has no camera, and Android Authority saw it push a tub and fold a small mat. Pick up the floor first.
