Robot vacuums, by floor problem
Start with your floor problem, not a model number
Most robot vacuums quit at a doorway sill of about 20mm. Most roundups will not tell you that, because they are ranking products rather than answering a problem. We compile what the manufacturers actually publish, and link every number to the page it came from.
- Models covered
- 23
- Specs with a source link
- 115
- Figures makers withhold
- 44
- Units we claim to have tested
- 0
Everyone in this category says they tested twenty machines this year. We have not tested any, and we say so. What we did instead was read every manufacturer page we could reach, put 115 published figures in one place with a link on each, and record the 44 they decline to publish rather than filling those in from a guess. The full method.
What we would buy, by problem
The top pick from each roundup. Prices are live where we have them and absent where we do not — we never print a remembered number.

Six floor problems
Every competitor organizes by product rank and buries the problem in a subheading. The measured search data says buyers do the opposite, so this site is organized the way people actually shop.
Pet hair
Robot vacuums for pet hair
Shedding, long hair, litter and dander. The brush spec matters more than the suction number.
Carpet
Robot vacuums for carpet and rugs
High pile, area rugs, fringe and the suction figures that do not mean what you think.
Hard floors
Robot vacuums for hard floors
Hardwood, laminate, tile and the dark-floor sensor problem nobody warns you about.

Mopping
Robot vacuums that mop
Pad, roller or retracting arm — three mop mechanisms and what each one is actually good at.

Why this site is different
Every number is a link
Each published figure carries the URL it came from and the date it was retrieved. Click one. If it does not match, tell us and we will correct it.
The gaps are shown
Where a manufacturer publishes nothing, the cell reads Not published. We never substitute a rival's number or a review site's estimate.
Criteria before products
Every roundup states what it ranked on before it names anything, and every roundup names a pick to skip.
Prices are live or absent
A price renders only from a live feed while that feed is fresh. Otherwise the button says Check price and shows no number.

How Bristle & Bot is funded
Affiliate commission. When you buy through a link here we earn a percentage at no extra cost to you, as an Amazon Associate. That is the whole business model — no sponsored placements, no paid inclusion, and no free units accepted from manufacturers. Commission cannot change the rankings, because the criteria are published before the products are chosen and every figure is linked to its source so you can check the reasoning yourself.
