Choose Roomba Max 705 Vac (W155020) if…

A vacuum-only package is the deliberate requirement and a suitable current W155020 purchase is verified.
You accept regular inspection and brush/dock care rather than assuming anti-tangle means maintenance-free.

Choose Roborock Q7 M5+ (auto-empty dock) if…

You actually want occasional mopping and accept the detachable module’s upkeep.
The Q7 M5+ auto-empty configuration fits the dry-run and dock routine you have checked.

Keep what you have if…

Keep the existing robot if it already handles hair and rugs and you do not want another maintenance system.
Pause if heavy pet hair on carpet is the deciding problem: the available evidence does not establish a universal winner for that task.
Do not pick on suction claims alone; test the actual floor, brush cleanup, caster and dock bag routine.

Editorial scope

United States buying scope: iRobot Roomba Max 705 Vac with AutoEmpty dock, black model W155020, Best Buy SKU 10202351 versus Roborock Q7 M5+ with RockDock Plus auto-empty dock, black; not the charge-only Q7 M5 or water-refill Q7 M5 Max+. Other sizes, bundles or regional versions require a separate check.

The differences that matter

3 decision factors shown. Unknowns remain visible.

Decision factorRoomba Max 705 Vac (W155020)Roborock Q7 M5+ (auto-empty dock)

Does the buyer want a robot mop at all?

Roomba Max 705 Vac is a vacuum-only package. Q7 M5+ is a hybrid with detachable mopping hardware, so it can run without the mop module but still brings a mop workflow into the purchase.

How often will a pet home need to handle dock debris?

Both manufacturers advertise long periods between bag changes, but shedding volume, floor area and cleaning frequency alter the actual routine. Compare bag replacement and robot brush upkeep together.

Check before you buy

Confirm that a vacuum-only device is the goal; if considering Q7 M5+, decide whether to remove and store its detachable mop module.
Name the pet's hair length, shedding level, floor type and rug pile; verify them during an actual run rather than using suction figures as a proxy.
Inspect brush ends, side brush, caster wheel, filter and dock bag after several runs to understand real maintenance.
Check model/color: iRobot W155020 black (not W155220 white); Roborock Q7 M5+ black with auto-empty dock (not M5 or M5 Max+).
Check current seller, stock, return window and availability of replacement bags/brushes before ordering.

What remains uncertain

This is an exploratory comparison; demand evidence supports the task more strongly than the exact pair.
No usable matched pet-hair test establishes a winner; placeholder review values are not scores.
Manufacturer dock-emptying maxima do not establish the interval in a particular pet home.
The cited Roomba retailer page showed no new-condition stock; verify exact item condition and seller.

Decide whether you want to own mopping equipment at all

A pet-hair household may want automated dry pickup without water tanks, wet pads or another mop-care routine. That makes the distinction between a vacuum-only robot and a vacuum-and-mop hybrid worth examining even when the hybrid can run with its mop removed.

This comparison covers the black Roomba Max 705 Vac W155020 with AutoEmpty Dock and the black Roborock Q7 M5+ with RockDock Plus. The comparison is an exploratory purchase task: the demand evidence supports the household problem more clearly than a frequent exact A/B buying choice. It is not a popularity ranking or a controlled pet-hair test.

For a home that only wants dry pickup

Consider the Roomba when the actual requirement is a vacuum-only package and you have confirmed a suitable current seller. iRobot describes the selected 705 Vac with dual rubber brushes and an AutoEmpty dock, without a robot mop. That can fit a buyer who deliberately does not want to own or maintain wet-cleaning attachments. Exact iRobot model

Do not turn the brush description into a promise of zero hair maintenance. The relevant question is whether the brush, caster, bin and station care suit the hair and surfaces in your home. This research does not contain a usable matched test establishing that the exact Roomba reliably solves those conditions better than Q7 M5+.

Availability also matters. The cited Best Buy page showed no new-condition stock when checked. Treat a product page as an identity reference and verify the current seller, condition and support route before considering it an available purchase. The black W155020 should not silently become the differently identified white variant.

For occasional mopping with the option to remove the attachment

Consider Q7 M5+ when you actually want its hybrid arrangement and accept the extra equipment. Roborock documents a detachable mop module and an auto-empty dock. Removing the mop for a dry run is a different proposition from buying a vacuum-only product: you still own the attachment and need to understand its care and setup. Q7 M5+ configuration

Confirm the plus model and dock. The charge-only Q7 M5 and differently configured Q7 M5 Max+ should not be substituted into the comparison because the family names look similar. The dock and water-handling arrangements change the ownership routine.

If you never want to mop, decide whether keeping unused equipment is acceptable rather than assuming a longer feature list is automatically beneficial. If you occasionally do, test the floor and rug routine with the module configured according to the instructions.

For long-haired pets and carpet

Keep the performance question open until you have relevant evidence. TechGearLab's Q7 M5+ review reports brush tangling and limitations for carpet or pet hair in its test. That is a reason to examine the cleanup routine, not proof that the Roomba wins the same job. Q7 M5+ test context

The research did not obtain a usable public Roomba pet-hair result from the cited comparison material. A placeholder number on a page is not a result and is not used here as a zero score. We do not fill the missing result with a manufacturer suction claim or an assumption about brush material.

Where a suitable trial is available, check the actual rug pile and hair, including what remains in the brush and dock after the run. Your evaluation should include the owner work that matters to you, not only whether the robot finishes moving around the room.

For fewer trips to empty a dust container

Both selected docks describe extended intervals between bag changes under their respective conditions. Those maximum estimates do not tell you the interval in a particular pet home. Shedding, floor area and the material collected change the load. iRobot dock description · Roborock dock description

Check access to the bag and the availability of the consumables you will need. An automatic-emptying feature is useful when its complete maintenance path is simpler for you; it does not establish that no manual inspection or cleaning remains.

When to keep the vacuum that keeps up

Keep it if daily fur and debris are already under control and the new purchase has no specific job to improve. A suction headline cannot establish pickup on your carpet or eliminate an unidentified maintenance problem.

If a replacement is justified, select a vacuum-only or detachable-mop routine deliberately, confirm the exact dock and current item condition, and leave unsupported performance claims out of the decision. That is more useful than declaring a pet-hair winner from two product descriptions and unrelated review conditions.
