Dyson R1 Nurovi Dry · iRobot Roomba 205 DustCompactor Combo

At $549 the R1 keeps the R2’s navigation and the same 21,000 Pa suction on the same 352 mm chassis. What the lower price removes is wet cleaning, not sensing: the R2 costs more for mop hardware and a washing dock, and both robots map the same way.

Onboard compaction removes the auto-empty base, not the dock: the 205 still ships with and charges on a dock, and what it drops is the bag compartment and the bags. The saving is real but modest. iRobot’s Dirt Disposal Bags run about $17 to $20 for a 3-pack and each bag is rated at up to 75 days, so feeding a bagged model costs on the order of $30 to $35 a year.

Retractable mop reduces manual toggling, yet the arm mechanism adds mechanical complexity and scheduled maintenance that fixed-dual-tank combos avoid.

Anyone needing mopping in the same device

The R1 has no mop hardware at all. Buyers wanting wet cleaning need the R2 Wash+Dry or the R3 Spot+Scrub UV instead.

US buyers wanting to purchase immediately

No confirmed US ship date or retailer listing existed at launch; UK availability began same-day but the US window trails into later September.

Buyers who want independent verification first

No independent reviews, owner reports, or teardowns exist yet; every published figure so far traces back to Dyson's own launch materials.

Buyers comparing on published battery or sound figures

Dyson publishes run time and charge time but no battery capacity, no sound rating, and no onboard bin volume for the R1. Anyone shopping on those numbers has nothing to compare.

Homes with extensive high-pile carpet or shag

Retractable mop design conflicts with high-pile texture. Compaction capacity is tuned for typical homes; excessive shedding on shag may exceed seasonal capacity.

Owners requiring same-day multi-room wet-cleaning depth

Single water tank and mop pad limit wet-pass coverage per charge. Multi-floor or large wet-surface cleaning needs dedicated floor-cleaning passes.

Pet homes with daily hair volume needing auto-empty

Onboard compaction reduces but does not eliminate hair entanglement. High-shedding households may benefit from auto-empty docks despite dock footprint.
