Когда приходишь домой, лучше сразу разуваться в прихожей.

In Russian, the present tense is often used for habitual or general situations.

So Когда приходишь домой... means:

• When you come home...
• Whenever you come home...
• When one comes home...

It is not talking about one specific future occasion. It describes a general rule or routine.

If you wanted a one-time future meaning, Russian would more likely use a perfective future form, for example:

• Когда придёшь домой... = When you get home... / When you arrive home... on a specific future occasion.

So here приходишь shows a repeated, usual situation.

Russian often leaves out subject pronouns when they are clear from the verb form.

• приходишь = you come / you arrive
• the ending -ишь already shows ты

So the sentence does not need ты.

Also, this kind of sentence often has a general-you meaning, similar to English:

• When you come home, it’s better to take off your shoes right away in the entryway.

This you can really mean any person in that situation, not necessarily one specific person.

Домой is a very common adverb meaning homeward / to home / home.

Russian distinguishes between:

• домой = movement to home
• дома = being at home

So:

• Иду домой = I’m going home
• Я дома = I’m at home

You usually say приходишь домой, not приходишь в дом, unless you literally mean entering a house as a building in contrast to some other place.

Лучше literally means better, but in this kind of sentence it often means:

• it’s better to...
• you’d better...
• it is preferable to...

So:

• лучше сразу разуваться = it’s better to take your shoes off right away

This is a very common Russian pattern:

• Лучше подождать. = It’s better to wait.
• Лучше не спорить. = It’s better not to argue.

It sounds like advice or recommendation, not a strict command.

After лучше, Russian often uses the infinitive to say what action is recommended.

Structure:

• лучше + infinitive

Examples:

• Лучше уйти сейчас. = It’s better to leave now.
• Лучше сразу позвонить. = It’s better to call right away.

So лучше сразу разуваться literally means better to take off one’s shoes right away.

Разуваться means to take off one’s shoes.

It is reflexive because in Russian this action is commonly expressed as something you do to yourself:

• обуваться = to put shoes on
• разуваться = to take shoes off

The -ся ending often appears with verbs describing personal actions involving dressing, washing, getting ready, and so on.

Compare:

• одеваться = to get dressed
• раздеваться = to get undressed
• умываться = to wash one’s face

So разуваться is the normal everyday verb for taking your shoes off.

Both exist, but they differ by aspect:

• разуваться = imperfective
• разуться = perfective

In this sentence, the speaker is talking about a general repeated habit: whenever you come home, it is better to do this. For repeated or habitual actions, Russian usually prefers the imperfective:

• Когда приходишь домой, лучше сразу разуваться...

If you were talking about one specific occasion, the perfective could be more natural:

• Когда придёшь домой, лучше сразу разуться.

So the aspect matches the idea:

• repeated/general advice -> разуваться
• one completed occasion -> разуться

Сразу means right away, immediately, or straight away.

So:

• лучше сразу разуваться = it’s better to take your shoes off right away

It adds the idea that you should do it as soon as you enter, not later after walking farther into the home.

Because в прихожей here means in the hallway / in the entryway as the location where the action happens.

Russian uses:

• в + accusative for motion into
• в + prepositional for being in

So:

• идти в прихожую = to go into the entryway
• разуваться в прихожей = to take your shoes off in the entryway

Here the action of taking shoes off happens there, so Russian uses the location form в прихожей.

Прихожей is the prepositional singular form of прихожая.

Base form:

• прихожая = entryway / hallway

After в meaning in, Russian often uses the prepositional case:

• в прихожей = in the entryway

This noun belongs to the type of feminine nouns ending in -ая, so the prepositional singular ends in -ей.

Compare:

• новая комната -> в новой комнате
• большая прихожая -> в большой прихожей

Yes. That is exactly how it often sounds.

Russian frequently uses the second person singular for general statements, similar to English you meaning people in general.

So the sentence can mean:

• When you come home, it’s better to take your shoes off right away in the entryway.
• or more generally:
• When one comes home, it’s better to take off one’s shoes right away in the entryway.

In normal English, we usually still translate it with you, but grammatically and stylistically it is often a general principle.

Yes, Russian word order is fairly flexible, although different orders can change emphasis.

The original:

• Когда приходишь домой, лучше сразу разуваться в прихожей.

This is natural and neutral.

Other possible versions:

• Когда приходишь домой, в прихожей лучше сразу разуваться.
• Лучше сразу разуваться в прихожей, когда приходишь домой.

These alternatives are possible, but the original sounds very natural because it moves from:

1. the situation: when you come home
2. the recommendation: it’s better
3. the action: to take off your shoes right away
4. the location: in the entryway

Yes, but the meaning changes a little.

• лучше = it’s better / you’d better
  gives advice or recommendation

• надо / нужно = it is necessary / need to / should sounds stronger, more like necessity or obligation

Compare:

• Когда приходишь домой, лучше сразу разуваться в прихожей.
  = When you come home, it’s better to take your shoes off right away in the entryway.

• Когда приходишь домой, нужно сразу разуваться в прихожей.
  = When you come home, you need to take your shoes off right away in the entryway.

So лучше is softer and more like practical advice.

They are similar, but not always identical.

• приходить домой = to come home / arrive home
• возвращаться домой = to return home

Приходить домой focuses on the arrival itself.
Возвращаться домой emphasizes returning back from somewhere.

In many everyday contexts, both can work, but приходишь домой is very natural and simple in this sentence.

It can, but разуваться is more idiomatic for this everyday action.

Compare:

• разуваться = to take your shoes off
• снимать обувь = to remove footwear

Снимать обувь is understandable, but it sounds a bit more literal or formal.
For everyday speech, разуваться is the normal choice.

So in a sentence about household routine, разуваться sounds very natural.
