What to expect from the iRobot Roomba 105 Vac+

The iRobot Roomba 105 Vac+ is the Roomba 105 Vac with an AutoEmpty dock: a vacuum-only robot with ClearView lidar mapping and a three-stage cleaning system with a multi-surface brush and an edge-sweeping brush, on a dock that empties the bin into a bag that traps allergens as small as 0.7 microns and holds up to 75 days of debris. The app sets schedules per room, suction levels, passes and keep-out zones, and it works with Alexa, Siri and Google Assistant.

On paper the dock is the whole difference from the plain 105 Vac, and it is the convenience that matters most with pets or a larger home: the robot empties itself into the dock, and the full bag goes in the bin without a cloud of dust. The 105 Combo+ is the same idea with a mop pad added.

Vacuum Wars has reviewed it, as iRobot's cheapest self-emptying Roomba, but its findings are not part of this text yet. Our specifications list no suction figure, run time or bag size. For a self-emptying lidar robot whose test results we have summarized, look at the Roborock Q7 M5+, Wirecutter's top pick.

Based on the maker's specifications and our price data; none of our test sources has tested this model.

7,000 Pa
Mopping 1 fact
Mop type

How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.

no mop
Dock 4 facts
Empties the dust bin

The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.

yes
Bagless

The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.

no
Dust bag lasts

How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.

up to 75 days
Dock size (w × d × h)

The width, depth and height of the dock. Measure the spot you have in mind, and leave room for the lid and for the robot driving in.

8.4 × 6.7 × 11.5 in (21.3 × 17 × 29.2 cm)
Navigation and obstacles 2 facts
Navigation

Robot height

Robot diameter

How wide the robot is. Narrower gets between chair legs more easily, wider usually means a bigger dust bin.

Robot weight

What the robot weighs. It counts most if you carry it up a staircase every day.

6.2 lb (2.83 kg)
Dust bin in the robot

How much dust the robot holds before you empty it. It matters less with a self-emptying dock, which empties the bin after every run.

240 ml
Battery 2 facts
Battery capacity

The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.

3,000 mAh

Alexa, Google Assistant, Siri
Warranty

The warranty the maker gives in the United States.
