Why this won
Robot vacuums fail in two ways, and neither of them is suction. They fail at navigation — getting stuck under the same chair every night, missing a third of the room, or dying in a corner — and they fail at the human interface, meaning you have to empty a thimble-sized bin every second run until you stop bothering.
The Q7 Max+ solves both at a price that does not require a conversation with your partner. Everything above it in the range is buying you mopping, and mopping is where this entire category is still writing cheques it cannot cash.
The mopping problem, stated plainly
Almost every robot vacuum sold above $500 advertises mopping. Almost none of them mop. The mechanism on most is a water reservoir that dampens a microfibre pad which is then dragged across the floor at walking pace with roughly no downward pressure. On a lightly dusty floor this looks like it is working. On anything sticky it is redistribution.
The exceptions are the machines with spinning or oscillating pads and real downforce, and those start around $1,200. If mopping is the actual requirement, that is the price of entry, and we would rather tell you that than sell you a $700 compromise.
What the specs actually mean
| Spec | Figure | What it actually means |
|---|---|---|
| Suction | 5,500 Pa | Above roughly 4,000 Pa the differences stop being visible on domestic floors. Manufacturers keep raising it because it is the easiest number to raise. |
| Navigation | LiDAR mapping | The feature that decides whether it cleans the room or wanders it. Camera-only navigation is cheaper and worse in the dark. |
| Dock capacity | ~7 weeks | The real metric is how often you are involved. Seven weeks means you forget it exists, which is the entire point. |
| Height | 96 mm | Measure under your sofa before you buy anything. This is the specification that most often ruins the purchase. |

The rest of the field
How we decided
- 01Coverage: does it actually clean the whole floor, repeatedly, over weeks.
- 02Intervention rate: how often a human has to rescue, empty or reset it.
- 03Pet hair on low-pile carpet, the most common domestic failure case.
- 04Dock behaviour and long-term consumable costs.
- 05Honest assessment of mopping, weighted to nothing above $500 unless it works.
The bottom line
Buy the Q7 Max+ — but if you can hold out until the autumn refresh lands, hold out. If your budget is under $200 and your floors are mostly hard, the Eufy is a genuinely sensible purchase that we would not sneer at.
