It brings almost double the suction, 25,000Pa against 13,000Pa, runs a rated 230 minutes against 120, holds a 4.5L water tank and a 3.2L dock bag, and backs it with a three-year warranty against the Combo's one year. The iRobot Roomba Max 705 Combo counters with the broadest smart home list of the pair, adding Apple HomeKit, Samsung SmartThings and Matter, plus dual-band Wi-Fi and Bluetooth the Dreame does not carry. Both self-empty at the dock and wash, dry and lift their mops, and the Combo alone dispenses detergent automatically. Choose the Dreame D30 Ultra for suction, stamina and warranty; choose the iRobot Roomba Max 705 Combo if Apple Home, SmartThings or Matter support decides it for you.

What the differences mean

Suction power

The Dreame D30 Ultra moves 25,000Pa against the iRobot Roomba Max 705 Combo's 13,000Pa, close to double. On carpet and heavy pet hair that gap decides how many passes a room needs.

Battery life

The Dreame D30 Ultra is rated for 230 minutes and the iRobot Roomba Max 705 Combo for 120, so the Dreame cleans a larger home in one run while the Combo returns to recharge.

Warranty

The Dreame D30 Ultra carries a three-year warranty against one year on the iRobot Roomba Max 705 Combo, meaningful cover on a machine that carries a motor, a pump and a wash dock.

Connectivity

The iRobot Roomba Max 705 Combo supports both 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth; the Dreame D30 Ultra is 2.4 GHz only and has no Bluetooth. Setup on a dual-band network is more forgiving on the Combo.

Smart home support

The iRobot Roomba Max 705 Combo adds Apple HomeKit, Samsung SmartThings and Matter to the Alexa, Google Home and Home Assistant both share; the Dreame D30 Ultra supports only the latter three. Apple and Matter homes need the Combo.

Detergent

The iRobot Roomba Max 705 Combo dispenses cleaning solution automatically, while the Dreame D30 Ultra has no automatic detergent dispenser, so solution is added by hand. That is a small but daily convenience in the Combo's favour.

What owners say

Owners of the two split sharply on reliability. Dreame D30 Ultra owners describe a workhorse that runs quietly, maps accurately and lifts long pet hair without the brushes catching, and their complaints are mostly about money rather than function: the ongoing cost of pads, bags and brushes, and, after about a year, mop-pad detection failing on some units. iRobot Roomba Max 705 Combo owners who got a good unit praise the accurate mapping, smooth navigation and the AutoWash dock that empties, heat-washes and dries the mop; a large share, though, report failures in the first weeks, from false bin and tank errors and leaking docks to unfinished jobs and a buggy app, which is why its owner sentiment is the lower of the two.
